The present invention relates to a modular robotic system for processing biological samples, and methods of using the same.
Automated sample processing systems can receive samples (such as biological test samples) and process the samples for various purposes, such as extracting DNA from a biological sample, preparing a nucleic acid sample for sequencing, or conducting one or more assays on the sample. For example, the QIAGEN QIAsymphony® system is an automated system that can receive biological samples and isolate DNA. While such automated systems are useful in an experimental laboratory setting or a low-throughput laboratory, such systems do not scale well for a large-scale clinical diagnostic laboratory. For example, a large-scale clinical genetic sequencing laboratory may process hundreds or thousands of samples per day, including extracting nucleic acids from a sample and preparing the extracted nucleic acids for sequencing.

In some embodiments, the method further comprises routing the plate from the sample processing module to the second node using the second robotic arm; and routing the plate from the second node to the first node.

In some embodiments of the methods described above, the method further comprises monitoring a liquid waste volume in a plurality of liquid waste containers; and disposing of liquid waste contained with the plurality of liquid waste containers according to a liquid waste prioritization schedule.
In some embodiments of the methods described above, the plate is routed using a bidirectional plate transportation track.
The modular robotic system described herein can be quickly scaled-up to allow for high-throughput sample processing. The system includes a plurality of sample processing modules, and samples can be routed from one sample processing module to another sample processing module using a network of robotic arms and a bidirectional plate transportation track. The system can be divided into a plurality of cells, with a robotic arm routing plates within the cell. The multiple cells are interconnected by a bidirectional plate transportation track, which can transport a plate from a node within one cell to a node within another cell, which need not be adjacent. One or more sample processing modules are arranged along the perimeter of a cell, and the robotic arm can route a plate to or from a sample processing module within the cell. For example, the robotic arm can route a plate from a first sample processing module to a second sample processing module within the cell. The robotic arm can also route a plate to or from a node on the bidirectional plate transportation track within the cell to or from a sample processing module.
The modular robotic system can also include one or more support systems, such as a water supply system, a liquid waste disposal system, a vacuum system, or a compressed gas system. One or more of these support systems can interconnect the cells within the modular robotic system to provide laboratory infrastructure if needed to operate any one or more sample processing modules.
The modular robotic system described herein can be easily expanded to increase sample processing capacity by adding cells without needing to add substantial infrastructure or suspend operation of the modular robotic system. For example, the water supply system, the liquid waste disposal system, the vacuum system, and/or the compressed gas system can include a terminus through which the support system can be expanded to support an adjacent cell. In some embodiments, the bidirectional plate transportation track is expandable through a terminus, or an additional bidirectional plate transportation track can be installed (for example, above, below, or adjacent to the existing bidirectional plate transportation track). The relatively easy expansion of the modular robotic system allows for rapid scale-up of the system, which relieves an otherwise substantial burden on a quickly growing clinical laboratory.
The configuration of the modular robotic system can also allow for rapid routing of plates (for example, sample plates) from a first sample processing module in a first cell to a second sample processing module in a second cell, which may be non-adjacent (that is, spaced by one or more cells). A robotic arm can route a plate to a first node of a plate transportation track (which may be bidirectional). Once the plate is at the first node of the plate transportation track, it can be transported to any other node on the plate transportation track in a single step. That is, to transport the plate from a first node to a second node, there is no need for the plate to stop at an intermediate node or robotic arm. For example, in some embodiments, a first robotic arm routes a plate to a first node; the plate is transported from the first node to a second node, the second node being inaccessible by the first robotic arm; and a second robotic arm routes the plate to a sample processing module, wherein a third robotic arm is disposed between the first robotic arm and the second robotic arm (the third robotic arm being accessible to a node between the first node and the second node), and the third robotic arm is bypassed when the plate is transported from the first node to the second node. Using this method, efficiency is maximized because no plate is more than three movement steps from any sample processing module in the modular robotic system. In a first step, a plate is routed from a first sample processing module to node i by robotic arm i within cell i. In a second step, the plate is transported along the plate transportation track directly from the node i to node n within cell n. In the third step, the plat is routed from node n to a second sample processing module by robotic arm n.
In some embodiments, there is a method of processing a biological sample in a modular robotic system, comprising: sending movement information to a first robotic arm to route a plate to a first node; transporting the plate from the first node to a second node inaccessible by the first robotic arm; and sending movement information to a second robotic arm to route the plate to a sample processing module; wherein a third robotic arm is disposed between the first robotic arm and the second robotic arm, and the third robotic arm is bypassed when the plate is transported from the first node to the second node.
In another advantage of the modular robotic system described herein, samples can be processed bidirectionally. In previous automated systems, samples are processed in a unidirectional manner; the sample is processed in a first sample processing module, then a downstream second sample processing module, then a downstream third sample processing module. In contrast, using the modular robotic system described herein, a sample can be processed in a first sample processing module in a first cell, be transported to a second cell and processed by a second sample processing module in the second cell, then be transported back to the first cell to be processed by a third sample processing module in the first cell. In some embodiments, there is provided a method of processing a biological sample in a modular robotic system, comprising: sending movement information to a first robotic arm to route a plate to a first node; transporting the plate from the first node to a second node, the second node inaccessible by the first robotic arm; sending movement information to a second robotic arm to route the plate to a sample processing module; sending movement information to the second robotic arm to route the plate from the sample processing module to the second node; and transporting the plate from the second node to the first node.
The modular robotic system utilizing the bidirectional plate transportation track provides several advantages over previous automated systems. First, the modular robotic system can efficiently process multiple sample plates with different defined workflow processes. For example, if a first sample plate is processed by sample processing module A, then sample processing module B, then sample processing module C, then sample processing module D, whereas a second sample plate is processed by sample processing module A, then sample processing module D, then sample processing module B, a unidirectional system would require an additional sample processing module B downstream of sample processing module D. In contrast, in the modular robotic system describe herein, sample processing modules A, B, and C can be located in a first cell and sample processing module D can be located in a second cell. The second sample plate can be processed at sample processing module A in the first cell, transported to the second cell to be processed by sample module D, then returned to the first cell using the bidirectional plate transportation track to be processed by sample processing modules B and C in the first cell.
The configuration of the modular robotic system also allows for load balancing when one or more of the sample processing modules operates at a lower throughput rate than other sample processing modules in a given defined workflow process. For example, if a defined workflow process requires a sample be processed by sample processing module A, then sample processing module B, then sample processing module C, but sample processing module B operates at half the throughput as sample processing modules A and C, then twice the number of sample processing module B would be required to utilize the full capacity of sample processing modules A and C. Full capacity may not be necessary at the initial stage of operation of the modular robotic system; however scale up would require the addition of a second sample processing module B. Adding a second sample processing module B to the same cell that contains sample processing module A, sample processing module C, and the first sample processing module B may not be practical due to special limitations or the need to suspend operation of automated system (for example, due to safety reasons during the addition of infrastructure). Using the configuration of the modular robotic system described herein, the second sample processing module B can be added to a different cell without needing to suspend operation of the other sample processing modules or cells.
In another advantage, the modular robotic system described herein can remain in operation if a given sample processing module breaks down or needs to be suspended for maintenance by including a redundant sample processing module elsewhere in the modular robotic system. For example, using the workflow process described above (A→B→C), the modular robotic system can be equipped with a redundant sample processing module B. If the first sample processing module B is suspended for any reason, the modular robotic system can continue to operate using the redundant sample processing module B.
The modular robotic system can dynamically route a sample plate to a sample processing module based on stateful data and a defined workflow process. The sample processing module to which the sample plate is routed can be selected based on a real-time load of the sample processing module. That is, if the sample processing module is in use (e.g., by processing a different sample plate) or suspended (e.g., due to malfunction or maintenance), the sample plate is routed to a holding nest or a redundant sample processing module. The holding nest or redundant sample processing module can be located in any cell within the modular robotic system, and the sample plate can be transported to the cell using the bidirectional plate transportation track. In some embodiments, there is a method of processing a biological sample in a modular robotic system, comprising sending movement information to a first robotic arm to receive a sample or consumable; and dynamically routing the sample or consumable to a first sample processing module based on stateful data and a defined workflow process, the first sample processing module selected from a plurality of redundant sample processing modules based on a real-time load of each of the redundant sample processing modules, wherein a first portion of the plurality of redundant sample processing modules is accessible by the first robotic arm and inaccessible by a second robotic arm, and wherein a second portion of the plurality of redundant sample processing modules is accessible by the second robotic arm and inaccessible by the first robotic arm. In some embodiments, the second portion of the plurality of redundant sample processing modules comprises the first sample processing module, and dynamically routing the sample comprises transporting the sample from a first node accessible by the first robotic arm and inaccessible by the second robotic arm to a second node accessible by the second robotic arm and inaccessible by the first robotic arm.
Another advantage of the modular robotic system described herein is the adaptability of modular robotic system to incorporate new defined workflow processes. Equipment in a clinical laboratory may be upgraded, new sample processing modules introduced, and new workflow processes developed. New sample processing modules can be added to the modular robotic system without suspending operation of the system by adding a new cell including the new sample processing module(s) or by adding the new sample processing module to the perimeter of an existing cell, if space allows.
As used herein, the singular forms “a,” “an,” and “the” include the plural reference unless the context clearly dictates otherwise.
Reference to “about” a value or parameter herein includes (and describes) variations that are directed to that value or parameter per se. For example, description referring to “about X” includes description of “X”.
The term “cell” refers to a section of the modular robotic system that includes a robotic arm and node on a bidirectional plate transportation track. The perimeter of the cell includes one or more modules (e.g., a sample processing module, input/output module, holding nest, etc.) that are directly accessible by the robotic arm of that cell, but not to a robotic arm of an adjacent cell.
A module or node that is “inaccessible” to a robotic arm means that the module or node is not directly accessible, and the robotic arm cannot directly move a plate to that module or node. A module or node that is accessible by a first robotic arm only through a plate transportation track or a second robotic arm is considered “inaccessible” to the first robotic arm.
An “input/output module” is any module or device that allows for (1) input, (2) output, or (3) both input and output of one or more plates in the modular robotic system. The plates can be transferred to or from (depending on the configuration) the input/output module by a robotic arm so that the plates can be routed throughout the modular robotic system. A user can also receive plates from or send plates to an input/output module so that they can be routed. Thus, direct interaction between a user and a robotic arm is not necessary for the modular robotic system to function.
A “manifold” is any device that provides a junction for a conduit, and can divide the conduit into two or more, three or more, four or more, five or more, six or more, seven or more, or eight or more conduits.
A “node” is a predetermined location on a plate transportation track that is associated with a particular cell of the modular robotic system.
It is understood that aspects and variations of the invention described herein include “consisting” and/or “consisting essentially of” aspects and variations.
Where a range of values is provided, it is to be understood that each intervening value between the upper and lower limit of that range, and any other stated or intervening value in that stated range, is encompassed within the scope of the present disclosure. Where the stated range includes upper or lower limits, ranges excluding either of those included limits are also included in the present disclosure.
It is to be understood that one, some or all of the properties of the various embodiments described herein may be combined to form other embodiments of the present invention.

The modular robotic system includes a plurality of sample processing modules (for example, modules for DNA extraction, sequencing library preparation, or sample preparation for one or more assays, modules for conducting assays), a bidirectional sample transportation track, and two or more robotic arms. The modular robotic system can further include a water supply system, a power supply system, a compressed gas system, a vacuum system, a data network, and/or a liquid waste disposal system. The water supply system is connected to the plurality of sample processing modules, and comprises a main water supply conduit, a plurality of water supply manifolds, and a main water supply conduit terminus. The liquid waste disposal system is also connected to the plurality of sample processing modules and comprises a main liquid waste disposal conduit, a pump, a plurality of liquid waste disposal manifolds, and a main liquid waste disposal conduit terminus. The bidirectional sample transportation track is configured to transport a sample (which may be contained within a plate) between two or more nodes, and the two or more robotic arms are configured to transport the sample between at least one of the nodes and at least one sample processing module. The power supply system is connected to a main power supply line (e.g., a building power supply) and to at least one of the sample processing modules. In some embodiments, the first robotic arm is configured to transport the sample between a first node and a first sample processing module, and a second robotic arm is configured to transport the sample between a second node and a second processing module. In some embodiments, the first robotic arm is not configured to not access the second node or the second sample processing module, and the second robotic arm is configured to not access the first node or the first sample processing module. In some embodiments, the robotic system comprises one or more safety features, such as one or more light curtains or a plate input/output module.
The modular robotic systems can receive one or more samples, such as biological samples, and process the samples using one or more sample processing modules. The sample processing modules can include automated equipment modules for extracting DNA from a sample, adding one or more reagents to a sample, or performing one or more assays on a sample. For example, the sample processing modules can include a liquid handling apparatus (such as a pipette system, a liquid dispenser, or a liquid aspirator), an incubator, a shaker or orbiter, or a device to perform an assay (such as a fluorimeter, a camera, or other imaging device). To operate, the sample processing modules generally rely on one or more sample processing support systems, such as a water supply system, a power supply system, a liquid waste disposal system, a data network, or a vacuum system, as further described herein. Further, the one or more sample processing systems may use one or more consumable components (such as reagents, pipette tips, or sample tubes), which can be routed through the modular robotic system as described herein.
The samples can be contained within a plate, such as a 24-sample plate, a 96-sample plate, or a 386-sample plate. The plate can hold the sample, for example, in an individual sample well or an individual sample tube. The plate or sample tube can include an identifier, such as a barcode, which can be used to associate the sample with stateful data, sample position (e.g., sample position within the plate, or sample position within the modular robotic system). The modular robotic system can receive the sample or plate through an input/output module, which can limit interaction between the robotic arms of the modular robotic system and a human user.
The modular robotic system can also receive one or more consumable components (for example, via the input/output module), and route the consumable components to a modular processing system. For example, in some embodiments, a plate includes one or more reagents or a plurality of pipette tips that are used by a sample processing module to process a sample. The consumable components can also be contained in a vial or other container.
The modular robotic system includes a backbone along the length of the system. One or more of the sample processing support system components, such as the main water supply conduit of the water supply system, the main power supply line of the power supply system, or the main liquid waste disposal conduit of the liquid waste disposal system can be disposed along the length of the modular robotic system. The plurality of sample processing modules can also be disposed along the length of the modular robotic system, for example along the perimeter of the backbone. The backbone also includes a bidirectional sample transportation track, which is configured to transport a sample between two or more nodes along the backbone. The two or more robotic arms are spaced along the backbone, and are each configured to transport a sample between at least one of the nodes and at least one of the sample processing modules.
The sample processing modules interface with one or more sample processing support systems, for example a water supply manifold, a power connector, or a liquid waste disposal manifold. The modular robotic system can modified, for example by adding a new sample processing module or replacing a first sample processing module with a second sample processing module, by joining or removing the sample processing module from the interface of the sample processing support system.
The modular robotic system can include two or more cells, each cell including a robotic arm. The cells are interconnected by a bidirectional plate transportation track, which includes a node within each cell that is accessible by the robotic arm within that cell, but not accessible by a robotic arm in any other cell. The cells include one or more modules around its perimeter, which are accessible by the robotic arm of that cell, but may not be accessible by the robotic arm of any adjacent cell. One or more support systems (e.g., a water supply system, a power supply system, a compressed gas system, a vacuum system, a data network, and/or a liquid waste disposal system) can run along the length of the modular robotic system, which can supply infrastructure to each of the cells within the robotic system. The modular robot support systems (e.g., the vacuum system, the compressed gas system, the liquid waste disposal system, and the water supply system) include one or more termini through which the system can be connected or expanded to an adjacent cell.
One or more support systems can interconnect the cells of the modular robotic system.

As illustrated in
The bidirectional plate transportation track allows for transportation of plates (such as sample plates or consumable plates) between cells of the modular robotic system. Each cell includes a robotic arm that can remove a plate from or place a plate on a node on the bidirectional plate transportation track. Once a plate is at a node on the bidirectional plate transportation track, the bidirectional plate transportation track can transport the plate to any other node on that track. The modular robotic system can include one or more (such as two or more, three or more, four or more, five or more, or six or more) bidirectional plate transportation tracks, which can provide additional nodes for a given cell. When the modular robotic system includes a plurality of plate transportation tracks, the tracks can be positioned above/below each other, adjacent to one another, or on either side of the robotic arm.
In some embodiments, the bidirectional plate transportation track includes a stationary track and a moveable component. The bidirectional plate transportation track can receive information to position the movable component to a node. A robotic arm can then place a plate on the movable component at the node, and the movable component can transport the plate to a second node along the plate transportation track. The bidirectional plate transportation track can be operated using an automation system, as described herein, which can route the plate based on defined workflow process and/or real-time workload of sample processing modules (for a sample plate) or based on consumable inventory levels of the sample processing modules (for a consumable plate).
In some embodiments, the modular robotic system includes one or more input/output modules. The input/output module allows plates to be safely placed in or removed from the modular robotic system without suspending operation of the modular robotic system or any component of the modular robotic system. In some embodiments, a given cell includes two or more input/output modules. In some embodiments, a given cell does not include an input/output module. In some embodiments, the input/output module is configured to receive one or more plates from a user, and the one or more plates can be routed within the modular robotic system by a robotic arm. In some embodiments, the input/output module is configured to receive one or more plates from a robotic arm. In some embodiments, the input/output module can hold 1 or more, 2 or more 5 or more, 10 or more, 25 or more, 50 or more, or 100 or more plates.
The plates inputted into the modular robotic system can include a barcode or other identifier. The plate can be placed on the input/output module and identified (for example, by scanning the barcode). Stateful data or a defined workflow process assigned to the plate, which can be stored in a database, can be accessed, and the plate can be routed to a location within the modular robotic system based on the stateful data and/or defined workflow process. Plates can also be summoned by user to remove the plate from the modular robotic system. For example, a user can input a plate identifier into a computer system. The computer system can determine the location of the plate with that plate identifier based on the stateful data of that plate. The computer system can then route the plate to the input/output module, where it can be removed by the user.
The input/output module is disposed along the perimeter of a cell of the modular robotic system, and can be accessed by the robotic arm associated with that cell. In some embodiments, the input/output module includes one or more trays, which can serve as input trays, output trays, or combination trays (i.e. for input and output). In some embodiments, the input/output module includes an input button or switch, which can be activated by a user to alert the system of a plate to be inputted into the system. Upon receiving an input signal, the modular robotic system can route the plate to a location within the modular robotic system based on stateful data and/or a defined workflow process for the plate. A robotic arm can remove the plate from the input/output module and route the plate to a sample processing module within the cell, a node on the bidirectional plate transportation track, or a holding nest.
A plate can be summoned to the output nest by identifying a plate in a computer system. The computer system identifies the location of the plate within the modular robotic system and sends movement data to the robotic arm of the cell that contains the plate. If the plate is in the same cell as the input/output module, the robotic arm can route the plate to the input/output module. If the plate is in a cell other than the cell having the input/output module, the robotic arm can route the plate to a node on a bidirectional track, and the plate can be transported using the bidirectional track to a node within a second cell comprising the input/output module. A robotic arm within the second cell can then route the plate to the input/output module.
As a robotic arm can retrieve plates from or place plates on the input/output module, and a user can retrieve plates from or place plates on the input/output module, in some embodiments the input/output module is equipped with a safety feature to prevent a collision between a user and a robotic arm. In some embodiments, a first light curtain is placed on one side of the input/output module and a second light curtain is placed on the opposite side of the input/output module. The light curtain is penetrated by the robotic arm when the robotic arm is routing a plate to or from the input/output module, and the second light curtain is penetrated by the user when the user is placing a plate on or retrieving a plate from the input/output module. When both light curtains are penetrated, motion of the robotic arm is suspended, which can avoid a collision between the robotic arm and the user.
In some embodiments, the modular robotic system includes a plate input/out module comprising a plate identifier configured to identify a plate or a type of plate; a plate nest, wherein at least one of the robotic arms is configured to retrieve a plate from the plate nest or transport a plate to the plate nest; and an input signaler configured to submit a request to a computer system, which operates the robotic arm to retrieve the plate from the plate nest. In some embodiments, the plate nest is positioned between a first light curtain and a second light curtain, and the first light curtain is positioned between the plate nest and the robotic arm, wherein simultaneous penetration of the first light curtain and the second light curtain suspends operation of the robotic arm. In some embodiments, in response to the computer system receiving a user request for an identified sample or an identified plate, the robotic arm is operable to retrieve the identified sample or the identified plate and position the identified sample or the identified plate within the plate nest of the input/output module.
In some embodiments, the modular robotic system includes a plate loading module. The plate loading module can be used to load a plurality of plates into the modular robotic system without the need to individual signal the computer system of a plate input. In some embodiments, the loading module is configured to determine how many plates of a particular plate type are in the plate loading module, for example, based on the height of a plate stack or a weight of a plate stack.
In some embodiments, the input/output module includes a temperature controlled compartment, which can hold one or more plates. A robotic arm can retrieve a plate or to place a plate within the compartment. Samples may be temperature sensitive, for example, and sample plates can be stored within the temperature controlled compartment. In some embodiments, the temperature controlled compartment is held at a temperature of about 15° C. or lower (such as about 10° C. or lower, about 4° C. or lower, about 0° C. or lower, about −10° C. or lower, or about −20° C. or lower). In some embodiments, the temperature controlled compartment is held at an elevated temperature, such as above 15° C. or lower (such as between 15° C. and about 100° C. or lower, between 20° C. and about 65° C., or between about 30° C. and about 40° C.). The temperature controlled compartment can optionally be used for temporary storage or incubation of one or more plates (i.e., as a holding nest). For example, in some embodiments, a sample is processed by a processing module, and the plate containing the sample is routed to the temperature controlled compartment for a period of time, and is then routed to a second sample processing module.
One or more of the input/output modules may be configured only for plate input into the modular robotic system. The module can accept one or more plates (for example, one or more stacks of plates), and a robotic arm can receive a plate from the module. The robotic arm may receive the plate from the module on an as-needed basis, routing the plate to a destination within the modular robotic system.
In some embodiments, one or more input/output modules are configured only for plate output. For example, used sample plates or consumable plates may be disposed of in a waste container. The modular robotic systems may include different waste containers to receive different types of waste. For example, one or more of the input/output modules may be a waste container configured to receive hazardous waste, non-hazardous waste, wet waste, or dry waste. In some embodiments, one or more of the waste containers receive clean or reusable waste, such as plate lids.
The sample processing modules are configured to receive a sample or sample plate from a robotic arm based on stateful data and the defined workflow process associated with the sample. The sample processing module can process the sample, and a robotic arm can retrieve the sample or sample plate form the sample processing module after completion of the sample processing. In some embodiments, a sample processing module transmits a signal to a computer system indicating that the sample has been received or the sample has been processed (or that one or more sample processing steps is complete). Upon receipt of the signal that the sample has been processed, the computer system can send instructions to the robotic arm to retrieve the sample from the sample processing module.
In some embodiments, the plurality of sample processing modules includes a nucleic acid (such as DNA or RNA) extraction module. The nucleic acid extraction module can receive a sample plate or sample that contains a patient sample (such as blood, saliva, or plasma) and isolates the nucleic acid in the sample. This can be done, for example, by adding one or more reagents to the sample, such as a lysis buffer, nucleic acid binding beads (which can be magnetic), a wash buffer, an elution buffer, water, or one or more other buffers. Nucleic acid extraction may also include a mixing step or an incubation step. After extraction of the nucleic acid, the completed processing step can be recorded by the computer system in the stateful data and the sample or sample plate can be transported to a second sample processing module according to the stateful data and the defined workflow process.
The plurality of sample processing modules can include a module for forming a nucleic acid library. For example, the sample processing module can received a sample or sample plate from a robotic arm after the sample has been processed by a nucleic acid extraction module, and processes the sample to attach sequencing adapters to the nucleic acid molecules. Formation of the nucleic acid library can include combining the sample with one or more reagents (such as buffers or enzymes), one or more adapter libraries (comprising adapters, which can optionally include a sample index molecular barcode, a specific nucleic acid sequence present in the sequencing adapter that can be used to identify the sequencing library of origin), or water. Formation of nucleic acid molecule may also include a mixing step (wherein the sample processing module comprises a mixer) or an incubation step (wherein the sample processing module optionally comprises an incubator, such as a heating block incubator). After formation of the nucleic acid sequencing library, the completed processing step can be recorded by the computer system in the stateful data and the sample or sample plate can be transported to an additional sample processing module, identified as processed by the processing module, and retained by the sample processing module or transported to an output bay or an input/output module of the modular robotic system, according to the stateful data and the defined workflow process.
In some embodiments, the sample processing modules can perform one or more pipetting functions (e.g., aspirating, dispensing, or mixing of liquids), shaking functions, heating functions, chilling functions, spinning functions (e.g., centrifugation), labeling functions (e.g., applying a barcode to a plate), sonicating functions, imaging functions, DNA quantization functions, applying or removing a heat seal, or applying or removing a plate lid.
The plurality of sample processing modules can also include a module for obtaining sample data. For example, the sample processing module can quantify an amount of nucleic acids in the sample, perform a real-time PCR assay, collect sample images, or a perform any other suitable assay step. Data collected from the sample can be sent to the computer system, which can be analyzed, for example, in the analytics results managements system (ARMS).
In some embodiments, one or more sample processing modules can combine the features described above. For example, in some embodiments, a single sample processing module can both extract nucleic acids and prepare a nucleic acid sequencing library.
Some or all of the sample processing modules in the modular robotic system can include specialized equipment for processing samples. Specialized equipment can include, a mixer, an incubator, a thermal cycler (i.e., a PCR machine), a pipette system (e.g., an automated multi-channel pipette), one or more liquid handlers (e.g., a liquid dispenser or a liquid aspirator), or one or more reagent troughs.
One or more of the sample processing modules can use reagents or consumables to process the samples. In some embodiments, one or more reagents (such as buffers, sequencing adapter libraries, or capture probe libraries) are contained in a reagent plate (which may be a multi-well reagent plate). The multi-well reagent plate may be useful, for example, when sample processing includes the use of several different reagents or when several samples within a sample plate are processed using different reagents. The contents of each well of the reagent plate (such as volume and type of reagent) can be reflected in a database, and the database can be updated when reagent is withdrawn from the plate. The reagent plate can be received by the sample processing module in a similar manner as the sample or sample plate. For example, the reagent plate can be received by from a robotic arm. The reagent plate can remain at the sample processing module, or it can optionally be transported to a second sample processing module (such as a redundant sample processing module). For example, a second sample processing module can submit a request for the reagent plate to the computer system, and the computer system can send instructions to a robotic arm to retrieve the reagent plate from the first sample processing module, and the reagent plate can then be transported to the second sample processing module. In some embodiments, the reagent plate is inputted into the modular robotic system using the input/output module or a plate loading module. In some embodiments, the reagent plate, once used or emptied (or emptied below a predetermined threshold as monitored by the computer system) is transported to an output bay or the input/output module of the modular robotic system.
Consumables, such as disposable pipette tips (which can be used by the pipette system) or sample tubes, can also be received by the sample processing module. The consumable may be arranged in a plate, which allows for easy transportation throughout the modular robotic system. A plate comprising a consumable can be referred to as a “consumable plate” (although the plate itself may be reusable). In some embodiments, a sample is transferred from a sample plate to a consumable plate (for example a consumable plate containing sample tubes), after which the consumable plate can be referred to as the sample plate for purposes of the stateful data and the defined workflow process. A sample processing module can receive a consumable plate from a robotic arm. The consumable plate may be inputted into the modular robotic system using the input/output module or a plate loading module. The contents of the consumable plate can be reflected in a database, and the database can be updated when a consumable from the plate is used or a sample is transferred to the consumable plate. The consumable plate can remain at the sample processing module, or it can optionally be transported to a second sample processing module (such as a redundant sample processing module). For example, a second sample processing module can submit a request for the consumable plate to the computer system, and the computer system can send instructions to a robotic arm to retrieve the consumable plate from the first sample processing module, and the reagent plate can then be transported to the second sample processing module. In some embodiments, the consumable plate, once used or emptied (or emptied below a predetermined threshold as monitored by the computer system) is transported to an output bay or the input/output module of the modular robotic system.
In some embodiments, the modular robotic system includes a vacuum system, which can supply vacuum to one or more sample processing modules. The vacuum system includes a main vacuum conduit connected to a vacuum source (such as a pump) and one or more vacuum manifolds. In some embodiments, each cell of the modular robotic system includes a vacuum manifold, although it is contemplated that a vacuum manifold could provide vacuum to two or more cells. When the modular robotic system includes two or more vacuum manifolds, the main vacuum conduit can connect the vacuum source to the first vacuum manifold, and the main vacuum conduit can continue from the first vacuum manifold to a second vacuum manifold. The vacuum system can also include a terminus at the end of the main vacuum conduit, which can be a valve or cap (which may be threaded). The main vacuum conduit can be extended from the terminus to extend the modular robotic system and provide vacuum to another cell. The vacuum system optionally includes a pressure gauge (e.g., a pressure transmitter) or pressure regulator disposed along the main vacuum conduit. The pressure gauge or pressure regulator can send or receive pressure information to or from the automation system.
The modular robotic system optionally includes a vacuum modular integration unit, which may be part of the vacuum system or part of the sample processing module, which is disposed between the vacuum manifold and the functional components of the sample processing module. The vacuum modular integration unit can include a filter, a pressure gauge (e.g., a pressure transmitter) or a pressure regulator, and/or an overflow container. The filter limits aerosolized debris from entering the vacuum source, and the overflow container can limit liquids from the sample processing module from entering the vacuum source. The pressure gauge and/or pressure regulator ensures proper function of the vacuum in the sample processing module.
The vacuum system can include a plurality of valves disposed between the sample processing modules connected to the vacuum system and the one or more vacuum manifolds, which may be part of the vacuum module integration unit. The valve can be operable (for example, by the automation system) selectively open only when vacuum to another sample processing module from the vacuum system is prevented. Simultaneous use of the vacuum system by too many sample processing modules may result in an unreliable decrease in vacuum pressure. This fluctuation in vacuum pressure can be minimized by restricting the number of sample processing systems that can simultaneously access vacuum system by controlling the valve. In some embodiments, only three or fewer, or only two or fewer sample processing module may simultaneously accesses the vacuum from the vacuum system. In some embodiments, only one sample processing module at any time can access the vacuum from the vacuum system. The valve can be operable to selectively open according to a vacuum system prioritization schedule, which can be managed by the automation system.
In some embodiments, the modular robotic system comprises a vacuum system connected to two or more sample processing module, which may be in the same cell or in different cells of the modular robotic system, the vacuum system comprising a main vacuum conduit and one or more vacuum manifolds. In some embodiments, each cell of the modular robotic system comprises a vacuum manifold. In some embodiments the vacuum system further comprises a vacuum system terminus, such as a valve or a cap, which can be used to extend the vacuum system, and may be disposed at the end of the main vacuum conduit. In some embodiments, the vacuum system further comprises a valve disposed between one of the one or more vacuum and one of the two or more sample processing modules. In some embodiments, the valve is operable to selectively open only when vacuum to any other sample processing module from the vacuum system is prevented. In some embodiments, the valve is operable to selectively open according to a vacuum system prioritization schedule.
In some embodiments, the modular robotic system includes a compressed gas system, which can supply compressed gas to one or more sample processing modules. The compressed gas may be, for example, air or an inert gas (such as nitrogen). The compressed gas system includes a main compressed gas conduit, which is connected to a compressed gas source (such as a compressed gas tank or a pump) and one or more compressed gas manifolds. In some embodiments, each cell of the modular robotic system includes a compressed gas manifold, although it is contemplated that a compressed gas manifold can provide compressed gas to two or more cells. When the modular robotic system includes two or more compressed gas manifolds, the main compressed gas conduit can connect the compressed gas source to the first compressed gas manifold, and the main compressed gas conduit can continue from the first compressed gas manifold to a second compressed gas manifold. The compressed gas system can also include a terminus at the end of the main compressed gas conduit, which can be a valve or a cap (which may be threaded). The main compressed gas conduit can be extended from the terminus to extend the infrastructure of the modular robotic system and provide compressed gas to another cell. The compressed gas system optionally includes a pressure gauge (e.g., a pressure transmitter) and/or a pressure regulator disposed along the main compressed gas conduit. In some embodiments, the pressure gauge or pressure regulator can send or receive pressure information to or from the automation system.
The compressed gas manifold is fluidly connected to one or more sample processing modules by a conduit. A valve is disposed along the conduit connecting the compressed gas manifold to the sample processing module, which can be opened when the sample processing module is connected to the compressed gas manifold, or closed when the conduit is not connected to a sample processing module.
The compressed gas system can include a plurality of valves disposed between the sample processing modules connected to the compressed gas system and the one or more compressed gas manifolds. The valve can be operable (for example, by the automation system) selectively open only when compressed gas to another sample processing module from the vacuum system is prevented. Simultaneous use of the compressed gas system by too many sample processing modules may result in an undesirable fluctuation in gas pressure. This fluctuation in pressure can be minimized by restricting the number of sample processing systems that can simultaneously access compressed gas system by controlling the valve. In some embodiments, only three or fewer, or only two or fewer sample processing module may simultaneously accesses the compressed gas from the compressed gas system. In some embodiments, only one sample processing module at any time can access the compressed gas from the compressed gas system. The valve can be operable to selectively open according to a compressed gas system prioritization schedule, which can be managed by the automation system.
In some embodiment, the modular robotic system comprises a compressed gas system connected to two or more sample processing modules, which may be in the same cell or in different cells, the compressed gas system comprising a main compressed gas supply conduit and one or more compressed gas manifolds. In some embodiments, the compressed gas system comprises a compressed gas system terminus, such as a valve or a cap, which may be used to connect or extend the compressed gas system to an adjacent cell, and which may be located at the end of the main compressed gas supply conduit. In some embodiments, the compressed gas system further comprises a valve disposed between one of the sample processing modules and one of the compressed gas manifolds. The valve may be operable to electively open only when compressed gas to any other sample processing module from the compressed gas system is prevented. In some embodiments, the valve is operable to selectively open according to a compressed gas system prioritization schedule.
In some embodiments, the modular robotic system described herein includes a liquid waste disposal system, which can receive liquid waste generated by one or more sample processing modules and transport the liquid waste to a sewer system or liquid waste container. The sample processing modules generate liquid waste from, for example spent reagents or biohazardous waste from the samples, which is periodically or continuously removed from the sample processing module to allow for continuous operation. The liquid waste can be manually removed from the sample processing modules; however such manual removal risks spills and/or contamination, or may require temporary suspension of the sample processing module. The liquid waste disposal system described herein promotes continuous operation of the modular robotic system.
The liquid waste disposal system includes a main liquid waste conduit and one or more liquid waste disposal manifolds. The main liquid waste conduit is connected at one end to a sewer system or a liquid waste container. In some embodiments, each cell of the modular robotic system includes a liquid waste manifold, although it is contemplated that a liquid waste manifold could be interconnected to two or more cells. The main liquid waste conduit is connected to the liquid waste manifold, and can continue to extend beyond the liquid waste manifold to a terminus or to a second liquid waste manifold at an adjacent cell. The terminus or the main liquid waste conduit can be a valve or a cap (which may be threaded). The main liquid waste conduit can be extended from the terminus, for example to provide the liquid waste disposal system to an additional cell of the modular robotic system. The liquid waste manifold can also be connected to one or more sample processing modules by a conduit, which may include a valve disposed along the conduit.
In some embodiments, a liquid waste module integration unit connects the liquid waste manifold to the sample processing module (or the liquid waste module integration unit may be part of the sample processing module itself). A liquid waste module integration unit is provided for each sample processing module connected to the liquid waste management system. The liquid waste module integration unit includes a container and a pump. Liquid waste flows from the sample processing module to into the container via a conduit. The liquid waste container is connected to the pump by a second conduit, which is connected to the liquid waste manifold by a third conduit. Liquid waste accumulates in the container until a signal is received by the module integration unit to dispose of the liquid waste. Liquid waste, such as biohazardous liquid waste, may accumulate in the container for treatment, which may require an incubation period prior to disposal. Upon receiving a signal, the pump operates to pump the liquid waste from the container and into the liquid waste manifold. Optionally, the module integration unit includes a control valve which opens when the pump is in operation to control flow of the liquid waste into the liquid waste disposal system. In some embodiments, the control valve is located along the conduit connecting the modular integration unit and the waste manifold. The container can include a level sensor (such as a scale, conductive sensor, mechanical sensor, or any other level sensor), which can measure the volume of the liquid waste in the container. The module integration unit can also include a pressure gauge (e.g., a pressure transmitter) or pressure regulator disposed along conduit connecting the pump to the liquid waste manifold. Optionally, the modular integration unit includes a spill sensor, which can detect an overflow or spill from the container.
Optionally, the liquid waste disposal system is controlled to avoid overloading the liquid waste disposal system or a connected sewer system. During operation of the modular robotic system, liquid waste is disposed of through the liquid waste disposal system. If too much liquid waste is disposed of at the same time, the liquid waste system or sewer system could become overwhelmed, resulting in dangerous liquid waste backflow or overflow. To alleviate this risk, the liquid waste (which may be stored in the liquid waste containers) can be disposed of through the liquid waste system according to a liquid waste prioritization schedule. When the liquid waste prioritization schedule permits disposal of liquid waste from a liquid waste container (either in one of the sample processing modules or one of the liquid waste module integration unit), the pump in the liquid waste module integration unit is operated and/or the control valve is opened to allow the liquid waste to flow into the liquid waste manifold. The liquid waste can then flow through the main liquid waste conduit and to the drain, sewer or main liquid waste container.
In some embodiments, the liquid waste prioritization schedule limits the number of liquid waste containers from which liquid waste can simultaneously flow. In some embodiments, the liquid waste prioritization schedule allows liquid waste to flow from a single liquid waste container at a time. In some embodiments, the liquid waste prioritization schedule allows liquid waste to simultaneously flow from a maximum of two, three, four, five, or six liquid waste containers at a time. The liquid waste prioritization selects the liquid waste container from which liquid waste flows out of based on one or more factors, such as, but not limited to: fullness of the liquid waste container; rate of liquid waste generation by the associate sample processing module; time the liquid waste has incubated in the liquid waste container; and frequency of use of the associated sample processing module.
In some embodiments, the modular robotic system comprises a liquid waste disposal system connected to two or more sample processing, which may be in the same cell or in different cells, the liquid waste disposal system comprising a main liquid waste disposal conduit and done or more liquid waste disposal manifolds. In some embodiments, each cell has its own liquid waste disposal manifold. In some embodiments, the liquid waste disposal system comprises a liquid waste disposal system terminus, such as a valve or a cap, which can be used to connect or extend the liquid waste disposal system to an adjacent cell, and which can be disposed at the end of the main liquid waste disposal conduit. In some embodiments, the liquid waste disposal system comprises a valve, pump, or regulator disposed between one of the one or more liquid waste disposal manifolds and one of the sample processing modules. The valve, pump or regulator may be operable to electively open or pump liquid waste only when the flow of liquid waste from any other sample processing module is prevented. In some embodiments, the valve, pump, or regulator is operable to selectively open according to a liquid waste disposal system prioritization schedule.
In some embodiments, the modular robotic system described herein includes a water supply system, which can deliver water (such as filtered or deionized water) to one or more sample processing modules. The water supply system includes a main water supply conduit and one or more water supply manifolds. The main water supply conduit is connected to a water source and a water supply manifold. The main water supply conduit can be extended from the water supply manifold to an adjacent cell (where it can connect to a water supply manifold in that cell) or to a terminus (such as a valve or a cap, which may be threaded). The water supply system includes one or more conduits branching from the water supply manifold, which can be connected to a sample processing module, a water supply module integration unit (which may be part of the sample processing module) or a terminus (such as a valve or a cap, which may be threaded). When the conduit is connected to a sample processing module or a water supply module integration unit, a valve or threaded connector is optionally disposed along the conduit. The water supply system optionally includes a pressure gauge (e.g., a pressure transmitter) and/or a pressure regulator disposed along the main water supply conduit, preferably upstream of the first water supply manifold connected to the main water supply conduit. In some embodiments, a spill sensor is disposed on or adjacent to the water manifold, which is configured to detect water leaking from the water supply conduit.
The water supply module integration unit includes a water manifold, which is connected to the water supply manifold disposed along the main water supply conduit. One or more conduits can branch from the water manifold in the water supply module integration unit to connect to one or more components of the sample processing module (such as a dispenser). A valve can be disposed along the conduit connecting the water manifold in the water supply module integration unit to the component of the water supply module. The valve can be closed when no component is connected to the water manifold and opened when a component is connected, thereby allowing water to be supplied to the component. The water supply module integration unit can include a pressure gauge (e.g., a pressure transmitter) or pressure regulator, which monitors or controls the water pressure delivered to the water manifold within the water supply module integration unit. In some embodiments, the water supply modular integration unit includes a spill sensor, which is configured to detect water spilled with in the water supply modular integration unit.
In some embodiments, the modular robotic system comprises a water supply system connected to one or more sample processing modules, which may be in the same cell or in different cells, the water supply system comprising a main supply conduit and one or more water supply manifolds. In some embodiments, each cell in the modular robotic system comprises a water supply manifold. In some embodiments, the water system supply system includes a water system supply terminus, such as a valve or a cap, which can be used to connect or extend the water supply terminus to an adjacent cell, and which may be disposed at the end of the water supply system. In some embodiments a valve and/or a pressure regulator is disposed between a water supply manifold and a sample processing module. In some embodiments, the water supply system comprises a flow sensor and/or a pressure regulator disposed along the main water supply conduit.
In some embodiments, the modular robotic system includes a power supply system configured to provide power and/or a data network connection to one or more sample processing modules. The power supply system includes a main power line (e.g., a building power line) connected to one or more main control panels. Each cell of the module robotic system can be associated with a separate main control panel, although it is contemplated that a single main control panel can be configured to provide power and/or a data network to two or more cells. The power line can provide three-phase power to the main control power. For example, the main power line can provide three-phase 208 VAC power to the main control panel. The main control panel can include a power distribution module (PDM), one or more circuit breakers (AC/DC), a transformer, and/or a direct current power supply (for example a 24 VDC power supply). The main control panel can output three-phase alternating current, single-phase alternating current (at one or more frequencies), and/or direct current, one or more of which may be connected to one or more sample processing modules or one or more modular integration units (which may be part of the sample processing module). For example, in some embodiments, the main control panel can output three-phase 208 VAC, single-phase 120 VAC, single-phase 240 VAC, and/or 24 VDC power, one or more of which may be connected to one or more sample processing modules or one or more modular integration units (which may be part of the sample processing module). The main control panel can optionally include an uninterruptible power supply, which can provide power to the cell in the event of a power interruption. The main control panel can also be configured to receive information from a data network (such as an Ethernet connection), and can include a managed network switch that distributes the data network to one or more sample processing modules and/or a power supply module integration unit.
A power supply module integration unit can receive power and/or data from the main control panel, and provide the power and/or data to a sample processing module. In some embodiments, the power supply module integration unit is configured to receive the three-phase alternating current, single-phase alternating current, and/or direct current power from the main control panel. In some embodiments, the power supply module integration unit is configured to receive the three-phase 208 VAC, single-phase 120 VAC, single-phase 240 VAC, and/or 24 VDC power from the main control panel. For example, in some embodiments, the power supply module integration until includes an AC power strip, which can receive 120 VAC power (or 240 VAC) from the main control panel. The sample processing module and/or one or more components of the sample processing module can plug into the AC power strip to receive the 120 VAC power (or 240 VAC). The power supply module integration unit can include a DC power distribution panel and/or DC power circuit breakers. The power supply module integration unit can receive the 24 VDC power from the main control panel, and the sample processing module and/or one or more components of the sample processing module can plug into the DC distribution panel to draw 24 VDC power. The power supply module integration unit can also include a data switch (e.g., an Ethernet switch), and optionally a serial (for example, a RS232 connection) to Ethernet converter, which can connect to the sample processing module and/or one or more components of the sample processing module. Optionally, the power supply module integration unit can be configured to supply three phase 208 VAC to one or more sample processing modules and/or one or more components of the sample processing module.
An exemplary main control panel is illustrated in
In some embodiments, the modular robotic system includes one or more power supply systems connected to a main power supply line and one or more sample processing modules, which may be in the same cell or in different cells. In some embodiments, the power supply system comprises a transformer configured to receive power form the main power supply line and supply three-phase 208 VAC, single-phase 120 VAC, single phase 240 VAC, or 24 VDC power. In some embodiments, the power supply system includes a battery.
In some embodiments, the modular robotic system includes a data network configured to provide communication between one or more sample processing modules and a computer system, and may include one or more data switches. In some embodiments, the data network is configured to provide communication between the computer system and one or more of the liquid waste disposal system, the water supply system, the vacuum system, and/or the compressed gas system. The data network can be part of the power supply system or a separate system.
Operation of the modular robotic system can be guided by an automation system. The automation system can provide management of the workflow processes, location of samples, location of plates (including sample plates and consumable plates), real-time workload of sample processing modules, and commands for moving the robotic arms in three-dimensional space.
The samples that enter the modular robotic system can have a defined workflow process. The workflow process indicates the steps for processing the sample using the sample processing modules, including the order of steps and order of sample processing modules that process the samples. In some embodiments, a sample plate containing samples is entered into the modular robotic system and all samples in that sample plate have the same workflow process. In some embodiments, the samples have different workflow processes (that is, one of the sample processing modules can reassign the samples contained within a sample plate to a new sample plate, or sample processing module may processes a portion of the samples in a given sample plate). The automation system may permit the deployment of a custom laboratory workflow processes. For example, the automation system may provide functionality for a user to create a graphical diagram to model different laboratory equipment and diagnostics, and may permit the user to customize the timing, decision-making, and other test variables of laboratory analytics. The automation system may further provide functionality to permit a user to define and/or deploy one or more workflow processes based on user-generated diagrams, and such workflow processes may be modified dynamically by the user. As a sample or plate progresses through a defined workflow process, the completed processing steps can be recorded as part of the sample and/or plate's stateful data.
The automation system may generate and send commands to the one or more robotics arms to allow the robotics arms to move in three-dimensional space, or generate and send commands to the bidirectional plate transportation track to transport a plate from a first node to a second node within the modular robotic system. Such commands may also permit the one or more robotics arms to interface with a pneumatics system to utilize pressurized air for grasping and releasing one or more plates. The commands can also provide movement information to a robotic arm and/or bidirectional plate transportation track to route or transport a plate to a location within the modular robotic system, such as a node on a plate transportation track, a sample processing module, a holding nest, and/or an input/output module.
The automated system can further include a lab tracker, which facilitates physical location management of the one or more robotic arms and/or plates (including sample plates and consumable plates). For example, the lab tracker may be configured as a database which stores positional information of all physical objects for a given point in time. When a plate is transported or routed within the modular robotic system, the location of the plate can be recorded as part of the stateful data of the sample and/or plate.
The automation system can further manage operation of the sample processing modules, for example by managing when the sample processing module is in use or when the sample processing module is available to process additional samples. Plates can be dynamically routed to a particular sample processing module based on the real-time load of the sample processing module. Managing operation of the sample processing modules may also include monitoring the consumables inventory of a sample processing module. When a particular sample processing module is low or empty on a particular consumable (for example, pipette tips), a plate containing that consumable can be routed to the sample processing module. If a defined workflow process for a sample or sample plate includes the use of a particular sample processing module, the plate is routed to an available sample processing module. For example, if a sample plate is to be processed by DNA extraction sample processing module, and the modular robotic system includes two redundant DNA extraction sample processing module, and the first DNA extraction sample processing module is unavailable (such as due to its being in use, a malfunction, or unavailability of one or more consumables), the plate is routed to the second DNA extraction sample processing module even if not the most proximal DNA extraction sample processing module.
In some embodiments, there is provided a method of processing a biological sample in a modular robotic system, comprising sending movement information to a first robotic arm to receive a sample plate; and dynamically routing the sample plate to a selected sample processing module based on stateful data and a defined workflow process, the sample processing module selected from a plurality of sample processing modules (which may be redundant) based on a real-time load of each of the sample processing modules, wherein a first portion of the plurality of sample processing modules is accessible by the first robotic arm and inaccessible by a second robotic arm, and wherein a second portion of the plurality of sample processing modules is accessible by the second robotic arm and inaccessible by the first robotic arm. In some embodiments, the second portion of the plurality of sample processing modules comprises the selected sample processing module, and dynamically routing the plate comprises transporting the sample from a first node accessible by the first robotic arm and inaccessible by the second robotic arm to a second node accessible by the second robotic arm and inaccessible by the first robotic arm. Once the plate is routed to the sample processing module, one or more samples contained by the plate can be processed.
The automation system can also provide additional functions for monitoring and/or controlling the modular robotic system. For example, the automation system can monitor and/or control pressure sensors, regulators, valves, spill sensors, and volumes in waste containers. If an undesirable condition is detected, such as a triggered spill sensor, the automation system can suspend operation of a sample processing module or a robotic arm. The automation system can further control the liquid waste management system to operate pumps and/or control valves to allow emptying of liquid waste held in a liquid waste container based on a real-time monitoring of the liquid waste container emptying of other liquid waste containers in the modular robotic system, as further described herein. In some embodiments a method described herein includes monitoring a liquid waste volume in a plurality of liquid waste containers; and disposing of liquid waste contained with the plurality of liquid waste containers according to a liquid waste prioritization schedule.
The modular robotic system can further receive one or more consumable plates, and route the one or more consumable plates to a sample processing module. The consumable plates can contain, for example, items consumed by the sample processing modules during sample processing or priming of equipment on the sample processing module. For example, the consumable plate can include sample tubes, pipette tips, or one or more buffers. The consumable plates can be inputted into the modular robotic system, for example via the input/output module. The automation system can receive consumable inventory information from one or more sample processing modules, which indicates the inventory level of one or more consumables at the sample processing module. Once the inventory level is at or below a predetermined threshold for a particular consumable at a given sample processing module, the automated system can route a consumable plate containing that consumable to the sample processing module with the low inventory. For example, the automation system can send movement information to a robotic arm, which receives the consumable plate, and routes the consumable plate to the designated sample processing module. For example, the robotic arm can directly deliver the consumable plate to the sample processing plate when the robotic arm is contained within the same cell as the sample processing module. If the sample processing module is in a different cell, the robotic arm can route the consumable plate to a node on a bidirectional plate transportation track, and the consumable plate be routed to the appropriate cell along the bidirectional plate transportation track (for example by the automation system sending movement information to the bidirectional plate transportation track). Once the consumable plate is transported to the appropriate cell (that is, the cell with the sample processing module with low inventory for that consumable), the robotic arm within that cell can route the consumable plate from the node within the cell to the sample processing module, thus delivering the consumable to the sample processing module. The robotic arm can also retrieve the spent consumable plate from the sample processing module, and the spent consumable plate can be routed to the output nest to be removed from the modular robotic system. In some embodiments, the method further comprises monitoring a liquid waste volume in a plurality of liquid waste containers; and disposing of liquid waste contained with the plurality of liquid waste containers according to a liquid waste prioritization schedule.
The modular robotic system can receive or output plates (such as sample plates or spent consumable plates) through the input/output module. The input/output module can receive a single plate or a plurality of plate (e.g., a stack of plates). In some embodiments, the input/output module determines the number of plates in a stack of plates based on the weight or the height of stack. In some embodiments, the input/output module includes a plate identifier (e.g., barcode) reader, which can read a plate identifier on the one or more plates, and transmit the plate identifier to the automation system. The automation system can access a database to determine the type of plates and/or the samples or type of consumable contained within the plate. Based on the contents of the plate and any defined workflow process associated with the sample on the plate, the automation system can route the plate to a sample processing module or a holding nest by sending movement information to one or more robotic arms or a bidirectional plate transportation track. In some embodiments, the method further comprises monitoring a liquid waste volume in a plurality of liquid waste containers; and disposing of liquid waste contained with the plurality of liquid waste containers according to a liquid waste prioritization schedule.
