The present disclosure is directed to robotic laundry devices, systems, and methods.
Automating and outsourcing mundane, time-consuming household chores to robotic devices is increasingly common. Time saving home robots include, for example, floor vacuuming and floor washing robots. Outsourcing responsibilities include, for example, engaging grocery shopping and delivery services, and manually operated and human-operator dependent laundry washing and dry-cleaning pick up and return services.
Many homes are appointed with a dedicated washer and dryer for family use. Domestic washers and dryers are increasingly sophisticated and include IoT connectivity features and push notifications for alerting users about cycle progress and energy and resource usage. These technologically advanced machines, however, require human interaction and cannot eliminate the time required for processing loads of laundry in the home. Although more modern, “high efficiency” machines are equipped with sensors for metering water usage and dryer temperatures, the efficiency gains are capped by the constraints of sequentially processing single loads of laundry. Grey water is output to the city water and sewer system for mitigation with each load of laundry processed. Energy is consumed with each load of laundry washed and dried.
Households can outsource laundry chores to gig worker services and/or laundromat facilities for a fee in exchange for time. Laundromats and gig services offering residential mixed load laundering services, however, require human interaction for intake and sorting of dirty laundry, transferring loads from washer to dryer, and then manually folding clean laundry. These are costly processes as measured in time, energy consumption, water consumption, and wastewater output, and they rely on human intervention to keep the process running at every transition and throughout several process steps. This invites delays at every stage. Because these processes are human-dependent and inefficient, the costs are passed along to customers outsourcing their laundry for cleaning. Human-reliant laundering services also require that employees touch the belongings of the customer, potentially exposing the employee to contaminants in the dirty laundry and potentially exposing the clean laundry to transferable pathogens, dust, hair, and other debris emanating from a laundromat employee. In addition to potentially introducing undesirable contact contamination from the employees processing the loads of laundry, a privacy barrier is breached. Outsourcing household laundry to a laundromat or gig economy worker involves employees interacting with customers' personal belongings including bodily worn garments.
Industrial laundry services exist for handling uniform, batched business-related items, such as batches of hospital or hotel bed sheets, batches of medical scrubs, and batches of hotel towels, each batch having consistent characteristics between and within loads for determining expectedly consistent washing and drying processes. Such industrial machines are tailor-made to accept one type of laundry item of one size or style. For example, unique folding machines exist to accept a dedicated one of washed flat sheets, fitted sheets, hotel towels, and hotel bathrobes. These machines require human operators to load the washed article into its dedicated machine, which is sized and designed to fold that one type and size of article. This type of process line relies on a human operator for properly aligning and loading the clean article into the machine, which could introduce bodily contaminants, bacteria, and viral matter into the clean articles. Like laundromat services and gig workers washing in their home appliances, these industrial services rely on human intervention and potentially introduce bio-contaminants into clean loads of laundry. Because these services are only profitable by processing large volumes of like items, these industrial processors are generally subscription-based services for large clients like hotels and hospitals producing standard-size, repeat laundry articles and are not available to consumers at an individual household level. Additionally, these services are configured to combine laundry from more than one source and are not configured to isolate and process separate loads for individual households.
Autonomous robotic devices are provided to process loads of household laundry. Such devices eliminate human contact with deformable laundry articles. As such, the devices need to be designed to be efficient and reliable for replacing the common, human-dependent chore of laundry.

In this way, the gripper 3120 is able to grasp small articles successfully, articles such as baby socks and children's gloves, for example, without driving into them at full speed and potentially pushing them out of reach of the gripper fingers 3107a-b.
The controller 3005 is configured to instruct the at least one drive 3125a-c to raise the closed terminal gripper 3120a and the grasped at least one 12a of the plurality of deformable articles 12a-n to a hoist height H1 above the stationary floor 3110, leaving behind articles 12b-n in the received load, where “n” represents the maximum number of separable deformable articles in the received load of deformable laundry articles. As will subsequently be described with regard to implementations, the first gripper 3120a nearest the inlet end I can grasp more than one deformable article 12a-n from the pile of dirty laundry to hand off to the next arm 3115b in an adjacent work volume 3105b. As will be described in detail, the plurality of arms 3115a-c operate in sequence to grasp and release articles down the length of the channel 3100 such that by the third grasp by the third arm 3115c, the more than one initially grasped deformable articles are separated and a single article 12a is held aloft by the final arm 3115c adjacent the outlet O.
In implementations, the device 3000 can include one or more weight sensors disposed each of the plurality of arms 3115s-c, the one or more weight sensor being in operative communication with the controller 3005 and being configured to continuously detect a rate of change as each one of the plurality of deformable laundry articles is raised. The controller 3005 can then determine that one of the plurality of deformable laundry articles is raised to a hoist height when the one or more weight sensors detect an unchanging rate of change of measured weight because the article is lifted completely off the floor 3110 and is no longer supported by the floor 3110, therefore imparting a maximum downward force on the engaged arm 3115a. Additionally or alternatively, the at least one sensor of at least one of a downward angled sensor 3140a-c, a transversely angled sensor 3145a-c (e.g., having a field of view aimed across the channel from one side wall 3112c-d to another), and an upwardly angled sensor 3147a-c, can detect a position of the terminal gripper above the floor 3110 and output a signal to the controller indicative of this height position. Upon receiving the signal, the controller 3005 can then determine that the gripper 3120a is at a hoist height conducive for moving the article into an adjacent work volume 3105b for dropping there. Additionally or alternatively, one or more encoders (e.g., motor encoders 3157a-c, a′-c′, a″-c″,
As shown in
In implementations, the controller 3005 is configured to determine whether a terminal gripper 3120a-c missed grasping the article prior to hoisting to the hoist height H1. For example, after the first arm 3115a has hoisted, rotated, and opened the terminal gripper 3120a in a second work volume 3105b, the controller 3005 of the device 3000 can determine that the article is not present on the floor 3110 within the second work volume based on one or more sensor signals from the at least one sensor 3140a-c. The controller 3005 can then at least one of query and receive a signal from the at least one sensor 3140a in the first work volume 3105a and determine a location of the deformable article on the floor 3110 within the first work volume 3105a. The controller 3005 can then repeat the instructions of positioning the terminal gripper 3120a of the first arm 3115a at the determined location to grasp the at least one article 12a of the plurality of deformable articles 12a-n, grasping, raising, rotating, and releasing the article in the second work volume 3105b.
In implementations, as will be described subsequently with regard to the method of operation, the controller 3005 can execute a miss recovery routine. In implementations, the miss recovery routine comprises moving the target grip point 15 inward from an edge by a distance in a range of between about 10-20 mm (e.g., 10 mm, 1 mm, 12 mm, 13 m, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, 20 mm) in a direction toward the inlet end I with each subsequent attempt after a missed grab. Additionally or alternatively, in implementations, the controller 3005 can determine a center of mass of the mask of the at least one article 12a on the floor 3110 and move the targeted grip point 15 the toward the center of mass with each subsequent attempt after a missed grab. Alternatively, in implementations, the controller 3005 is configured to move the target grip point 15 to some other location within the area of the garment mask (e.g., mask 3800).
In implementations, the controller 3005 selects the alternate grip point locations randomly, or by iterating attempted grasps at alternate locations in a deterministic manner. This ensures that the gripper 3120 will find a graspable portion of the article 12, accounting for any spacing between extensions and the core of a garment, such as between sleeves and the torso portions of a shirt, which may place a center of mass in an open location not occupied by the article 12. Additionally or alternatively, in implementations, the controller 3005 is configured to create a bounding box 3805 around the mask 3800 of the article 12 as shown in
Additionally or alternatively, in implementations, after selecting the target grip point within the bounding box, the controller 3005 is configured to instruct the one or more drive motors 3125a-c to transit the gripper 3120 to a target location above the determined grip point, then slowly move down at a fraction of the transit speed in arriving at the target location. The controller 3005 instructs the at least one drive motor 3125a-c to press the gripper 3120 into the article and then retract to a distance at or around 2 cm while closing the fingers 3107a-b of the gripper 3120 around the grip point of the article. In this way, the gripper 3120 is able to grasp small articles successfully, articles such as baby socks and children's gloves, for example, without driving into them and potentially pushing them out of reach.
Each of the subsequent arms in the plurality of sequential arms 3115a-c similarly performs a grasp, rotation, and drop down the line of sequential arms 3115a-c and work volumes 3105a-c from the inlet end I to the outlet end O of the channel 3100. By performing sequential grasps, rotations, and drops the device 3000 increases the likelihood that each subsequent grasp will result in the terminal gripper 3120 of an arm 3115 retaining only a single article 12 in the final work volume 3105d for dropping through the outlet orifice 3135. By separating the load of the plurality of deformable articles 12a-n into single articles, the device 3000 is able to sort each one of the plurality of deformable articles 12a-n into a receiving bin 3202 configured to receive a single load of laundry having one or more common characteristics for improved washing and drying. Each article of the plurality of deformable articles 12a-n can be independently detected by the at least one sensor (at least one of a downward angled sensor 3140a-c, a transversely angled sensor 3145a-c, and an upwardly angled sensor 3147a-c), and the controller 3005 can determine one or more characteristics for batching the article into an associated bin 3202a-n. As shown in
Also as shown in
In implementations, as shown in
In this implementation, after an arm performs an article 12 hoist, the controller 3005 will evaluate a population count of an output sensor signal (e.g., one or more sensors 3140a-c, 3145a-c, 3147a-c) to determine whether an article is detected in an area under the engaged arm 3115. In implementations, the population count comprises the number of points in a point cloud, and the points comprise at least one of points that have been voxelized and points that have not been voxelized. Alternatively, in implementations, determining a population count indicative of a successful hoist comprises the controller 3005 identifying correlated points between 3D points in a depth map with RGB pixels in an RGB image of the hoisted article based on the output signal of one or more sensors (e.g., one or more sensors 3140a-c, 3145a-c, 3147a-c). This implementation of determining population count can also be used by the controller 3005 for classifying an article at the last hoist above the outlet orifice 3135 before dropping the article into a bin based on at least one of a detected article size and color.
If the population count is detected as large (e.g., at or above a threshold value indicative of an article 12 being detected), the controller 3005 determines that the arm 3115 and gripper 3120 grabbed and hoisted at least one article 12. If the population count is below a threshold value, the controller 3005 determines that the grab missed grasping an article, in which case the article is still on the floor 3110, or the article wasn't missed but is smaller than a threshold population count, e.g., a sock. The controller 3005 determines whether an article is on the floor by evaluation the mask 3800. If the mask processing indicates an empty floor, the controller 3005 determines the grab was successful and the article 12 in the gripper 3120 is small, therefore the floor beneath that arm is available for receiving a new article. If the controller 3005 analyzes the mask and determines the floor is not empty (e.g., an article 12 is detected on the floor 3110), the controller 3005 determines the floor 3110 is not available for receiving another article. In this instance when an article is detected in the gripper and on the floor 3110, either more than one article 12a-n had been deposited on the floor 3110 in the work volume 3105 and one article was hoisted and another left behind on the floor 3110, or the article in the hoisted gripper is large and extends down onto the floor 3110.
If the population count is below a threshold value and the floor mask does not indicate an article being present on the floor 3110, the floor 3110 is available to receive an article. This condition can indicate that the grab was successful, and the item hoisted is small (e.g., below a population count threshold). If the population count is below a threshold value and the floor mask indicates an article being present on the floor 3110, the work volume is not available for receiving another article. This condition indicates either a missed or dropped article or that a small item was successfully grabbed but another article remains on the floor 3110.
Additionally or alternatively to the above described conditions, in implementations, the controller 3005 is configured to account for shadows. For example, if an article is supposedly detected on the floor 3110 of the work volume 3105a of a hoisted arm 3115a, but the arm 3115b corresponding to the next sequential work volume 3105b is stowed, the controller 3005 determines the detected article is a shadow of the hoisted article 12 the engaged arm 3115 is waiting to move to the adjacent work volume 3105b. The controller 3005 can assume this is a shadow and not an article because the arm 3115 for the adjacent work volume 3105b would have tried to pick up the article 12 and would be in a hoisted position.
In implementations, the controller 3005 is configured to stop iterating the sequential grasps, hoists, rotations, and drops when each one of the plurality of deformable articles 12a-n exits the enclosed channel 3100 through the outlet orifice 3135 as a solitary deformable article and no deformable articles remain in the enclosed channel 3100 as detected by the one or more sensors (e.g., at least one of one or more downward angled sensors 3140a-c, one or more transversely angled sensors 3145a-c, and one or more upwardly angled sensors 3147a-c). As will be subsequently described, the controller 3005 is configured to determine that the enclosed channel 3100 is clear of any deformable articles before accepting a new load of dirty laundry (e.g., a new pile of deformable articles 12a′-n′) onto the stationary floor 3110 adjacent the intake end I.
Although the above implementations describe each of the plurality of arms 3115a-c rotating a grasped article 12 into an adjacent work volume and the associated terminal gripper 3120a-c releasing the article onto the floor 3110 in the adjacent work volume, additionally or alternatively, in implementations, one or more of the terminal grippers 3120a-c of the plurality of arms 3115a-c can simultaneously grasp at least one article 12a of the plurality of deformable articles 12a-n at a hoist height H1 without releasing the article onto the floor 3110 so that the article 12a is spread out. For example, as shown in
As shown in
Although
Turning to
In implementations, the sliding trap door 3131 is actuated by a drive motor 3320 in operable communication with the controller 3005 for selectively sealing and exposing the inlet orifice 3130a on demand. The drive motor 3320 can be configured to rotate a movable track 3325 to which the spring loaded hinge 3315 is attached. In implementations, the drive motor 3320 can be a low profile linear drive that enables the trapdoor assembly 3300 to have a low profile atop the enclosed channel 3100. As will be subsequently described, the low profile enables a box tipping assembly 3400 to be mounted in close proximity with the inlet orifice 3130a thereby minimizing or eliminating exposure of the box contents (e.g., one or more dirty articles 12, 12a-n) to the exterior and surrounding environment external to the enclosed channel 3100. This prevents the load of one or more deformable articles 12, 12a-n therein and any dirt, detritus, debris, and/or biological matter from falling outside the enclosed channel 3100. As will be described subsequently with regard to implementations, the box tipping assembly is designed to avoid contamination of the process line 100 at large and the exterior of the enclosed channel 3100 in particular by dirty laundry (e.g., one or more dirty articles 12, 12a-n). Only the cleanable interior surfaces of the enclosed channel 3100 are touched by dirty laundry released from a customer box.

Although the inlet orifice 3130a is describe as a selectively exposed orifice in the ceiling 3111 of the enclosed channel 3100 configured to receive a plurality of deformable articles from a box 3500 disposed above the orifice 3130a, other intake assemblies and methods are contemplated. As shown in

As described previously with regard to implementations, as shown in the system schematic of
Turning now to the outlet end O of the enclosed channel, the outlet orifice 3135 is configured to receive individually sorted articles therethrough for batching into sorted loads of laundry for washing. In implementations, such as that of
In implementations, as shown in
As previously described, in implementations, such as shown in
The autonomous separating and sorting robot 3000 is configured to provide the at least one deformable article 12 to one or more washing and drying devices 4000, and in implementations the autonomous separating and sorting robot 3000 comprises sensors configured to determine one or more characteristics of the at least one deformable article 12. The one or more characteristics can be, for example, material composition, fabric finish, load weight, color, size, volume, article type, and degree of dirtiness. In implementations, the autonomous separating and sorting robot 3000 communicates these characteristics to the controller 4005 of the one or more washing and drying devices 400 for determining parameters for a washing and drying cycle, parameters such as wash cycle temperature, cleaning and rinse agent amounts and concentrations, wash cycle duration (e.g., one or more soak and agitation cycles), number and duration of rinse cycles, soak cycle duration, washing cycle agitation speed (e.g., for delicate, normal, and heavy loads), maximum spin speed during fluid (e.g., water and/or chemicals) extraction, wash detergent selection and concentration, number of rinse cycles, drying air temperature, drying airflow rate, and a minimum size device 4000 in a cluster 4002 for receiving each load of at least one deformable article 12. Additionally or alternatively, in implementations, the autonomous separating and sorting robot 3000 is configured to estimate cycle duration and wash water requirements (e.g., for plant load balancing purposes across one or more clusters 4002).
In implementations, the wash parameters associated with the identified one or more characteristics are stored in a memory in communication with the controller 3005. The memory can be a memory 3010 of the separating and sorting device 3000 and additionally or alternatively can be a memory storage or database 235, 250, 240 in remote communication with the controller 3005 via the communication network 230. Because each load of household laundry contains articles of various types, sizes, materials, stains, and related wash requirements, each load may comprise more than one associated wash parameter. The wash parameters can be stored in a look up table cross referenced with one or more characteristics along with a default hierarchy for selecting washing and drying parameters based on two or more characteristics. For example, water temperature and agitation cycle duration associated with material type can trump parameters associated with load volume or weight. For example, a large load of laundry comprising several heavy cotton towels can be washed on warm water with vigorous agitation while a large load of thing cotton undergarments can be washed at more slow, gentle agitation speeds. The controller 3005 thus can be configured to determine wash parameters for each individual load of laundry based on the characteristics of the one or more deformable articles 12 in each individual load and communicate at least one of the one or more characteristics and washing and drying parameters associated with a bin 3202 to the one or more washing and drying devices 4000 receiving the bin 3202. Additionally or alternatively to the autonomous separating and sorting robot 3000 determining one or more characteristics of the at least one deformable article 12 for cross referencing with associated wash parameters, the wash parameters can be communicated to and received by a remote terminal 205 in communication with the communication network 230. A user of the remote terminal, e.g., the customer owning the one or more deformable articles, can provide predetermined wash parameters associated with a tagged (e.g., RFID label, bar code, QR code, etc.) container of dirty laundry articles 12a-n on an input screen of the remote terminal 205 or handheld device 245, and the provided predetermined parameters can be communicated to and stored in the memory 4010, 235, 240, 255 in communication with the controller 3005.
Because the one or more characteristics can include at least one of load size, fabric type, fabric finishes, wash cycle temperature, and article type (e.g., thick, water retaining items such as towels and jeans and thinner fabric items such as t-shirts and underwear), in implementations, at least one of the controller 4005 of the washing and drying device 4000 and remote terminal 205 determines optimum conditions for airflow, air temperature. and drying duration based on the load characteristics detected by the separating and sorting robot 3000. For example, the load characteristics can comprise two or more of the following load characteristics: the size of the load of laundry articles 12a-n relative to a size of a drum of a washing and drying robot 4000a-n, the fiber composition and fabric type (e.g., weave/knit type and looseness, length of fibers (staple) from which the fiber/yarn is spun, spin quality of the fiber/yarn, fuzziness, etc.) of one or more articles 12 in the load, fabric finishes of one or more articles 12 in the load, wash cycle temperature, and article type and thickness. The two or more load characteristics can be determined by the dirty laundry separating and sorting robot 3000 and communicated to the controller 4005 of the washing and drying robot 4000 and/or the remote terminal 205 by a controller 3305 of the dirty laundry separating and sorting robot 3000 via a wired or wireless network 230.
Turning to the system schematic of
The one or more deformable articles 12, 12a-n in a common bin 3202a-e are routed to a single washing and drying device 4000. In implementations, more than one bin 3202a-e can be routed to a single washing and drying device 4000 if the characteristics of the deformable articles therein are matching and/or compatible for washing together and without exceeding a load capacity of a washing and drying device 4000, as will be described subsequently with regard to implementations of load construction parameters. In implementations, the device 3000 comprises at least one fill sensor in communication with the controller 3005, and the at least one fill sensor is configured to detect an occupied volume of the one or more bins. In implementations, the fill sensor is an optical sensor focused on a minimum threshold fill line and a maximum threshold fill line disposed on an interior surface of one of the one or more bins 3202a-e positioned beneath the exit orifice. The optical fill sensor can be configured to detect whether the of one or more of the plurality of deformable articles received in the one of the one or more bins reaches or surpasses the minimum threshold fill line. In implementations, the maximum threshold fill line comprises a top edge of the one of the one or more bins 3202a-e. Additionally or alternatively, the fill sensor is configured to output a signal indicative of the occupied volume of the one of the one or more bins being with a threshold range between the minimum threshold fill line and maximum threshold fill line. Upon determining an occupied volume of the one of the one or more bins is within a threshold range indicative of being filled, the controller 3005 is further configured to instruct the load constructor 3200 to unload the filled one of the one or more bins 3202a-e containing the sorted plurality of deformable articles 12a-n to the autonomous combination washing and drying device 4000. In implementations, a filled volume of all deformable articles in a single bin 3202 should be less than a washing and drying device capacity. For example, the washing and drying device capacity can be in a range of between about 0.10 m{circumflex over ( )}3 to 0.20 m{circumflex over ( )}3. In implementations, the washing and drying device capacity can be at or about 0.17 m{circumflex over ( )}3. In implementations, the controller 3005 is configured to determine whether additional items can be added to a collection bin 3202. The controller 3005 can determine whether a deformable article 12 fits into the available bin based on a size estimate and previous bin fill level. For example, the controller 3005 can be configured to stop loading a bin 3202 that is in a range of between about one half to three quarters full.
Additionally or alternatively, as shown in
In implementations, the fill sensor is configured to output a signal indicative of the bin full condition. Upon receiving the bin full condition output signal, the controller 3005 is further configured to instruct the load constructor 3200 to unload the filled one of the one or more bins 3202a-e containing the sorted plurality of deformable articles 12a-n to one or more autonomous combination washing and drying machines 3000. In implementations, each of the one or more bins 3202a-e comprises an identification marker 3220a-e for associating with at least one of a identity of the bin and one or more characteristics of the one or more deformable articles sorted into the each of the one or more bins 3202a-e.
In implementations, as shown in
The parameters for determining combining bins can be stored on a local and/or remote memory in wired or wireless communication with a least one controller 3005, 4005. To prevent overfilling a washing and drying device 4000, the parameters can include one or more of the following limitations: ‘¾’ full bins shall not be combined with any other bins, a ‘½’ full bin may only be combined with a single ‘¼’ full bin, a ‘¼’ full bin may be combined with another ‘¼’ full bin or an ‘E’ bin, three “E” bins may be combined and a combined weight of all bins must be less than a threshold weight. For example, the threshold weight can be in a range of between about 10-20 kg. In implementations, the threshold weight is at or about 16 kg.
As previously described, in implementations the device 3000 comprises an actuatable load constructor 3200 in operable communication with the controller 3005. As shown in
Turning now to
In implementations, each of the maximum number of bins 3202 can be positioned on the load constructor 3200 at the start of a separating and sorting process for a load of deformable laundry articles 12a-n. Alternatively, the load constructor processor 3221 can call for the autonomous loading of a bin 3202 onto the load constructor 3200 upon receipt of a signal communicating of a detected condition comprising at least one of a start of a separating and sorting process, the identification of a new article characteristic associated with newly identified washing and drying parameters (e.g., color, fabric type, material thickness, stain identification, etc.) within a load of dirty laundry articles 12a-n, and detection of a bin full condition of a bin 3202 disposed on the load constructor 3200 prior to completing separating and sorting of a load of deformable laundry articles 12a-n.
For example, as shown in
As previously described, each of the one or more bins 3202a-e comprises an identification marker representative of the contents of the bin and linkable with a customer ID. In implementations, the identification marker comprises at least one of a machine-readable serial number, a bar code, a machine-readable QR code, an RFID code, NFC tag, a WIFI enabled tag, a ZIGBEE enabled tag, and an active radio telemetry system. In implementations, the controller 3005 can create a virtual tag in memory associated with a known location of one or more bins based on an initial location and subsequent locations as the one or more bins move through the process line 100, 100a-c. In implementations, the controller 3005 is in communication with a memory configured to store at least one relation comprising one of the one or more characteristics associated with the bin, the bin identification marker for each of the one or more bins, and a customer identity shared by the plurality of deformable articles received into the enclosed channel. In implementations, the controller 3005 is in communication with a communication network 230, and a remote terminal 205 in communication with the communication network is configured to receive a customer input comprising the one or more characteristics associated with the plurality of deformable articles.
Additionally or alternatively, in implementations, at least one sensor (e.g., one or more sensors 3140a-c, 3145a-c, 3147a-c) is configured to detect the one or more characteristics of each one of the plurality of deformable articles 12a-n and output a signal to the controller 3005 comprising the detected one or more characteristics. In implementations, the at least one sensor comprises at least one of a 3D camera, an IR sensor, a 2-D camera, LIDAR, LADAR, a sonar proximity sensor, an ultrasonic ranging sensor, a radar sensor, a pair of stereo depth cameras, a colorimeter for determining color of an article 12, and a spectrometer for determining fiber type of a deformable article 12. In implementations, the at least one sensor comprises at least one of a colorimeter and spectrometer disposed on or in the fingertips of the gripper fingers 3107a-b because these points come into close contact with the material of the article 12 for successful evaluation. Additionally or alternatively, the at least one sensor comprises at least one of a colorimeter and spectrometer disposed at least one of in a wall 3112a-d of the channel 3100 and along the floor 3110 such that an arm 3115 can hold a hoisted article against or immediately proximate the sensor. The one at least one sensor can further detect one or more stains disposed on a deformable article and flag the article in software for delivering to a bin 3202 marked for stain treatment in the washing and drying device 4000. In implementations, the at least one sensor comprises a camera (e.g., one or more sensors 3140a-c, 3145a-c, 3147a-c) associated with one or more of the plurality of work volumes outputs at least one of depth map, RGB images, and IR images. In implementations, the at least one sensor comprises a camera (e.g., one or more sensors 3140a-c, 3145a-c, 3147a-c) associated with one or more of the plurality of work volumes, the camera being configured to output 3-D image data to the controller 3005. Additionally or alternatively, the at least one sensor comprises a camera (e.g., one or more sensors 3140a-c, 3145a-c, 3147a-c) associated with one or more of the plurality of work volumes and the camera is configured to output one or more 2-D images to the controller 3005. As previously described, in implementations, the at least one sensor is a camera, and the camera is calibrated to at least one of the floor of the enclosed channel 3100 and one or more of the plurality of arms 3115a-c.
In implementations, the controller is configured to determine, based on a comparison of a received output signal of the at least one sensor to data stored in a memory in communication with the controller, at least one of an article type, an article color, an article size, and an article fabric. In implementations, at least one sensor is a 2-D camera, and the data associated with the deformable laundry article is size invariant image data comparable with database images of tagged articles and/or classes of articles.
In implementations, the memory comprises a neural network 300, and determining the one or more characteristics of each one of the plurality of deformable articles comprises processing the received output signal of the at least one sensor with a neural network classifier. In implementations, as shown in
For example, size is a particularly important characteristic of a deformable article because a large item (e.g., a bed sheet, comforter, tablecloth, large bathrobe, etc.) can envelop smaller items, preventing them from being washed or dried effectively. Therefore the controller 3005 will prevent mixing these items in a common (e.g., shared) bin 3202 for washing. The neural network 300, therefore can be used to determine whether a deformable article in the enclosed channel 3100 is of a large garment class. For example, in implementations such as that of
In other implementations, such as that of
As previously described with regard to implementations, the at least one of the controller 3005 and load constructor processor 3221 can determine a bin full condition based on at least one of a weight and a volume of each of the plurality of loaded bins 3202 on the load constructor 3200. As previously described with regard to implementations shown in
Additionally or alternatively, in implementations, the controller 3005 executes a crumple predictor routine for determining a volume of a separated article 12. The crumple predictor is trained by taking a picture of a suspended article, dropping the articles on the floor 3110 of the channel 3100 and taking a picture of the article on the floor 3110. The controller 3005 then computes a volume of the article on the floor 3110 from point cloud voxels of the detected article 12. The crumple predictor can be trained on a plurality of articles comprising a plurality of shapes, sizes, and volumes, and the controller 3005 can store that information in memory 3010 or database for estimating volumes of subsequently separated articles 12 suspended in the channel 3100.
Because articles 12a-n can pile in a pyramid during loading, the driven rollers 2145a-d of the plurality of conveyors 3105a-n are configured to rotate rapidly in opposite directions to “shake” the bin 3202 thereon and settle the contents therein from a pyramid to a more uniform height across the length and width of the bin 3202. Additionally or alternatively, the device 3000 comprises one or more plungers for pushing a just loaded article 12 into a bin 3202 and compressing the peak of any pyramid shaped deposited article.
As previously described with regard to implementations, at least one of the controller 3005 and load constructor processor 3221 can intelligently shift bins 3202a-n on the load constructor 3200 such that the plurality of deformable articles 12a-n are sorted into one or more bins based on what percent of the load of deformable articles 12a-n has been separated and sorted and what percent remains. Additionally or alternatively, the load constructor 3200 can fill each bin 3202a-n to a “bin full” state before starting to fill a second bin of the same type. Alternatively, the load constructor can fill two or more bins of the same article type (e.g., two light article bins), alternating between the two or more bins with each addition of an article of that type. When the separation and sorting process completes, the at least one of the controller 3005 and load constructor processor 3221 determines if the two or more bins of the same article type can be combined into a single washing and drying device 4000 without exceeding a threshold capacity.
As described previously, once the controller 3005 determines that all deformable articles of a plurality of deformable articles 12a-n received into the enclosed channel 3100 from a customer box 3500 are sorted into the one or more bins 3202a-e, the controller 3005 instructs the load constructor 3200 to convey the remaining bins thereon to one or more washing and drying devices 4000a-n. The controller 3005 then prepares the enclosed channel 3100 for receiving a next load of one or more deformable articles 12a-n. In implementations, as shown in
In implementations, the retractable cleaner 3600 comprises an actuatable cleaning drive motor in operable communication with the controller 3005. Upon determining that none of the plurality of deformable articles 12a-n remain on the stationary floor 3110 in any of the sequential work volumes 3005a-d, the controller 3005 is configured to instruct the retractable cleaner 3600 to advance from the inlet end I to the outlet end O of the enclosed channel 3100. In implementations, the drive motor extends a telescoping plunger 3612 or pusher arm disposed on an external face 3616 of the retractable cleaner 3600. As shown in
Additionally, in implementations, the device 3000 further comprises one or more UV lights in operable communication with the controller 3005 for cleaning the enclosed channel 3100. The one or more UV lights are configured to illuminate the one or more sequential work volumes 3105a-d of the enclosed channel 3100 after the retractable cleaner 3600 advances to the outlet end O and then retracts to the inlet end I. In implementations, the one or more UV lights are disposed on one or more interior surfaces of the enclosed channel 3100, and the controller 3005 is further configured to instruct the plurality of arms fully extend into the enclosed channel before the one or more UV lights are illuminated, thereby also cleaning the fully extended arms 3115a-c. This sanitizes the enclosed channel surfaces and the arms 3115a-c and associated grippers 3120a-d between separating and sorting successive loads of one or more dirty deformable articles 12a-n, thereby preventing the potential introduction of contaminants, pathogens, and other debris and dirty between loads of articles.
Turning back to
In implementations, the service line 3625 further comprises at least one of a vacuum line and a power conduit. Additionally, in implementations, the retractable cleaner 3600 further comprises a plurality of evacuation ports 3630a-n disposed along the continuous outer surface 3620 of the retractable cleaner facing the one or more interior surfaces of the enclosed channel. The plurality of evacuation ports 3630a-n is in operative communication with the vacuum line for suctioning remaining moisture from the one or more interior surfaces of the enclosed channel 3100 upon advancement of the retractable cleaner 3600 through the enclosed channel 3100. Additionally, in implementations, the retractable cleaner 3600 comprises a squeegee 3635 on a trailing edge of the continuous outer surface 3620 of the retractable cleaner 3600 facing the one or more interior surfaces of the enclosed channel.
As described with regard to implementations, the device 3000 comprises a plurality of arms 3115a-c for separating a plurality of deformable articles and intelligently sorting the articles one at a time into one or more batches for washing. As previously described, each of the plurality of arms 3115a-c is configured to pan, tilt, extend, and retract within an associated work volume 3105a-c of the enclosed channel 3100.
As shown in
Turning to
In implementations, the enclosed channel 3100 comprises a plurality of openings in a sidewall, each opening being configured to receive one of the plurality of arms 3115a-c therethrough. Implementations, as described with regard to
In implementations, as shown in
In the implementation of
As previously described with regard to implementations, each of the plurality of arms 3115a-c comprises at least one drive motor 3125a-c, a′-c′, a″-c″ schematically represented in
In implementations, each arm 3115 of the plurality of arms 3115a-c can include a tilt motor 3125b, b′, b″, c for raising and lowering the arm 3115 and associated terminal gripper 3120 with respect to the floor 3110, wherein the floor 3110 is in a plane defined by axes LHX and LHY as shown in
As shown in
The one or more drive motors 3125a-c, a′-c′, a″-c″ associated with each arm 3115a-c can operate simultaneously, in some sub-combination, or alternate operating to move the each gripper 3120a-c to a location within the enclosed channel 3100 for engaging a deformable laundry article 12 disposed therein. Each gripper 3120a-c is configured to releasably engage the deformable laundry article 12 and operate at least one of independently of and in tandem with another of the grippers 3120a-c to at least one of raise and suspend the deformable laundry article above the floor 3110 of the enclosed channel 3100.
In implementations, each arm 3115, 3115a-c can comprise a rod, such as an extruded beam, configured to extend from an associated base 3118, 3118a-c. In implementations, an arm 3115 can have no joints along its length, and a length from end to end that measures between about 0.25 m and 4 m (e.g. 0.25 m, 0.5 m, 1.0 m, 1.25 m, 1.5 m, 1.75 m, 2.0 m, 2.25 m, 2.5 m, 2.75 m, 3.0 m, 3.25 m, 3.5 m, 3.75 m, 4.0 m). In implementations, each arm 3115 of the plurality of arms 3115a-c is an extendable arm comprising a fully extended length of between about 0.25 m and 4 m (e.g. 0.25 m, 0.5 m, 1.0 m, 1.25 m, 1.5 m, 1.75 m, 2.0 m, 2.25 m, 2.5 m, 2.75 m, 3.0 m, 3.25 m, 3.5 m, 3.75 m, 4.0 m). In examples, the extendable arm can include at least one of one or more flexible and/or compliant joints and two or more telescoping sections. In implementations, the at least one compliant joint comprises a compliant wrist disposed between the extendable rod of the arm 3115 and the terminal gripper 3120. Additionally or alternatively, the wrist of an arm 3115 comprises one or more of a swivel joint and hinge joint for bending the wrist and aligning the terminal gripper to close on a grippable edge of a hoisted article 12 rather than trying to pinch a planar surface.
Joints and telescoping arms can be implemented to accommodate space constraints, but the additional moving sections can create pinch points for potential entangling the deformable laundry article 12. Therefore, in implementations, each arm of the plurality of arms 3115a-c comprises no joints. In implementations, the motions of each arm 3115, 3115a-c have a resolution of +/−5 mm in all three cardinal directions (LHX, LHY, LZ). This precision enables alignment of an associated gripper 3120, 3120a-c before grabbing a grip point 15a-f on a deformable laundry article 12. In implementations, each arm 3115, 3115a-c moves the associated gripper 3120, 3120a-c within a spherical work volume having a radius defined by the arm 3115, 3115a-c. In implementations, the linear error introduced by degrees of pan and/or tilt at a full extension of the arm 3115, 3115a-c is +/−5 mm.
As previously described, in implementations, the two or more arms 3115, 3115a-c comprises three arms anchored along a length of the enclosed channel. In implementations, as shown in
In addition to pan, tilt, and extend motions, in implementations, additionally or alternatively, the controller 3005 is further configured to drive the at least one drive of an arm 3115 of the plurality of arms 3115a-c in at least one of alternating side-to-side and alternating up and down motions to shake one or more grasped deformable article 12 of the plurality of deformable articles at the hoist height. By shaking the terminal gripper 3120 at the hoist height, the arm 3115, 3115a-c can free any articles 12a-n that may be stuck together, e.g., statically attracted, or entangled. This is possible because the terminal grippers 3120 are designed to securely grasp an article 12.
As shown in the system schematic of
Additionally, each arm 3115, 3115a-c comprises a gripper drive 3172a-c and a gripper actuator 3174, 3174a-c in communication with at least one of the respective processors 3155, 3155a-c and the at least one controller 3005 of the system 400 (via a wireless or wired communication network 230). Additionally, in implementations, each arm 3115, 3115a-c comprises one or more gripper sensors 3176, 3176a-c (e.g., a Hall sensor for detecting an angular position of a gripper wrist that flexes relative to the longitudinal arm axis E) and fingertip pressure sensors disposed in the fingers of the gripper for detecting contact forces with an article of clothing and/or the workspace floor 3110.
As previously described, each arm 3115 of the plurality of arms 3115a-c terminates at an associated gripper 3120, 3120a-c. In implementations, each gripper 3120, including gripper fingers, can be manufactured from a lightweight, impact resistant material, such as aluminum or steel. In implementations, as shown in
In implementations, as shown in
The at least two actuatable fingers 3707a-b can rotate about parallel pivot points 3706a-b. In implementations, the at least two actuatable fingers 3707a-b are configured to be actuated by a drive assembly 3709 (e.g.,
In implementations, a gripper 3120 can comprise the following design factors shown in table 2:
In implementations, the following definitions apply to the design factors of table 2. Grip strength is the maximum force that can be applied to moving the deformable article 12. It can also be thought of as the force required to pull a deformable laundry article 12 out of a gripper 3120. The at least two actuatable fingers 3107a-b make contact with the deformable laundry article 12 and directly impart the force that moves the deformable laundry article 12 (grip strength). This force is due to a combination of friction (when the force is generally parallel to the gripping surface) and normal tension (for instance, when the deformable laundry article 12 is wrapped over one of the two or more fingers 3707a-b). In implementations, such as that depicted in
Grip force is the force the two or more fingers 3707a-b push against each other (when empty) or the deformable laundry article 12 (when engaged). The grip force is determined by the grip torque and the contact distance (distance between finger pivot 3706 and contact point with the deformable laundry article 12). If the deformable laundry article 12 is engaged at a single point, the grip force equals the grip torque divided by the contact distance. In embodiments, calculations are based on the center of the contact area defining the contact point. Strength-to-force ratio is the ratio between grip strength and grip force. In implementations, grip strength and grip force are directly proportional so that the ratio is fixed for a given combination of finger 3707, deformable laundry article 12 type and shape. In other implementations, grip strength and grip force have a sigmoidal relationship. For example, this applies to grippers 3120 that create a normal force or otherwise ‘lock’ the deformable laundry article 12 into place between the fingers 3707a-b. Grip torque is the torque on the joints of the fingers 3707a-b. This is dependent on the cable tension and gripper geometry and can be increased by increasing the lever arm in the gripper 3120, but this increases the gripper size. Cable tension is dependent on the motor torque and lever arm at the motor. This sets the minimum diameter of the cable. Cable tension can be increased by decreasing the motor lever arm, but in implementations using a pulley wheel, a minimum diameter is required to ensure the cable does not break. Motor torque is minimized to reduce cost and weight of the motor.
In other implementations, the grippers 3120, 3120a-b can comprise pneumatic actuators. A cable, or pneumatic tube, is snaked through the arm 3115. The gripper mechanism is driven by a linear motion, which is translated into finger rotation by linkages or pulleys. In implementations, the fingers 3107a-b are joined by linkages to one another and an actuatable cylinder. The pneumatic gripper 3120 is lightweight, quickly actuated, and built to withstand cycles on order of magnitude in the millions or higher. In implementations, at least one pneumatic tube runs through a hollow conduit extending the length of the arm 3115. In implementations, two pneumatic tubes run through the hollow conduit, each one of the pneumatic tubes configured to be in fluid connection with one of two sides of a pneumatic actuator. In implementations, the controller 3005 actuates the gripper 3120 to close (e.g., clamp shut) the fingers 3107a-b by pressurizing one side of a pneumatic actuator. In implementations, the controller 3005 actuates the gripper 3120 to open (e.g., spread apart) the fingers 3107a-b by pressurizing the other side of the pneumatic actuator. Additionally or alternatively, in implementations, the fingers can be held open by a cylinder and return spring assembly, which can be weak enough to allow any tangled deformable laundry article 12 to slip off the fingers. Pneumatic actuators have the advantage of being easy to seal against ingress of dirt and germs. Pneumatics actuators have the advantage of being easy to seal against ingress of dirt and germs. In implementations comprising a pneumatic cylinder at 100 psi, a gripper 3120 can comprise the following design factors shown in table 3:
Turning to
In implementations, the controller 3005 receives one or more signals from the plurality of sensors 3755a-d, 3765 and determines the application of a side-to-side force indicative of a deformable article being snagged on a first arm or terminal gripper while the terminal gripper of a subsequent arm of the plurality of arms grasps the article. In implementations, the controller 3005 receives one or more signals from the plurality of sensors 3755a-d, 3765 and determines the application of a threshold amount of axial force applied as the terminal gripper 3120 pushes against the floor 3110 of the channel 3100 to sweep up and grasp an article resting on the floor. For example, and article such as a thin silk scarf, may be smooth and comprises a low profile. The terminal gripper 3120 can comprise flexible fingers 3707a-b and be configured to accommodate being driven into the floor with a threshold amount of force (e.g., 1 lbf, 2 lbf, 3 lbf, e.g., 4.4N, 8.9N, 13.3N) while enabling the flexible fingers 3707a-b to be actuated in a grasping motion. In implementations, the controller 3005 receives one or more signals from the plurality of sensors 3755a-d, 3765 and determines the application of a threshold amount of axial force applied as the terminal gripper 3120 pushes against a pile of deformable articles to ensure the terminal gripper 3120 is positioned with the pile of deformable articles for successfully grasping at least one article.

Referring now to
In implementations, a method 3900 of autonomously (e.g., robotically) sorting a plurality of deformable laundry articles 12a-n into loads for washing, comprises receiving S3905, at a controller, a signal from at least one sensor disposed at least one of on, adjacent to, and within at least one of a plurality of sequential work volumes within an enclosed channel, the signal being indicative of at least one of the plurality of deformable laundry articles being disposed within at least one of the plurality of sequential work volumes. In implementations, the at least one sensor is disposed in a first bay or work volume of a continuous, enclosed channel comprising a plurality of sequential work volumes. The method comprises determining S3910, based on the received signal, a location of the at least one of the plurality of deformable articles on a stationary floor of the associated one of the plurality of sequential work volumes.
At the start of the separating and sorting process, all of the at least one of the plurality of deformable articles are disposed in a first work volume of the enclosed channel. As described previously with regard to implementations, the plurality of sequential work volumes 3105a-d are constituent to an enclosed channel 3100 and the stationary floor 3110 of the enclosed channel 3100 extends between an inlet end I and an outlet end O of the enclosed channel. A portion of the stationary floor 3110 adjacent the inlet end I is configured to receive thereon the plurality of deformable laundry articles 12a-n when introduced into the channel 3100. If the controller 3005 determines, based on the received signal, that a laundry article is not detected, in implementations, the method comprises receiving S3912 a second signal from another of the at least one sensor. For example, in implementations, the first signal can be at least one of a 2D and 3D image and the second signal can be another at least one of a 2D and 3D image. In implementations, the first and/or second signal can be, for example as shown in
The method comprises determining S3913 wherein at least one article 12 is detected in each of the work volumes. If no article is detected, the method concludes by sending a collection bin containing one or more separated and sorted deformable laundry articles 12 to one or more washing and drying robots 4000. If an article is detected in a work volume, the method comprises identifying S3915 a grip point on the article and instructing S3920 at least one drive of at least one of a plurality of arms 3115a-c disposed in series along the enclosed channel 3100 to at least one of rotate, tilt, extend, and retract a terminal gripper 3120 configured to selectively grasp at least one of the plurality of deformable laundry articles at the determined grip point. As described herein with regard to implementations, each one of the plurality of arms is associated with one of the plurality of sequential work volumes. The controller instructs an actuator of the terminal gripper to close on the at least one of the plurality of deformable laundry articles. The method comprises instructing the at least one drive to raise S3925 the closed terminal gripper and the grasped at least one of the plurality of deformable laundry articles to a hoist height above the stationary floor 3110, and move S3940 the gripper 3120 (e.g., at least one of pan, tilt, and extend, e.g., rotate) toward the outlet end O into an adjacent work volume 3105b-d. In implementations, the method comprises determining S3930 whether the gripper missed grasping the grip point and repeats the instructions of identifying S3915 a grip point, instructing the arm to pan, tilt, extend and/or retract the gripper to the grip point, instruct the gripper to grasp the grip point, and instruct the arm S3925 to raise the gripper and grasped article to a hoist height.
As described previously with regard to implementations, the method can comprise the controller 3005 executing a subroutine for a miss recovery if the controller 3005 determines the gripper has not grasped the article 12. In implementations, the miss recovery routine comprises moving the target grip point 15 inward from an detected edge of the one or more articles 12a-n by a distance in a range of between about 5-10 mm with each subsequent attempt after a missed grab (e.g., grasp by the gripper). Additionally or alternatively, in implementations, the controller 3005 can determine a center of mass of the mask of the at least one article 12 on the floor 3110 of the work volume and move the targeted grip point 15 from the outer most edge of the at least one article 12 toward the center of mass with each subsequent attempt after a missed grab.
In implementations, method comprises the controller 3005 selecting the alternate grip point locations randomly, or by iterating attempted grasps at alternate grip point locations in a deterministic manner. This ensures that the gripper 3120 will find a graspable portion of the article 12, accounting for any spacing between extensions and the core of a garment, such as between sleeves and the torso portions of a shirt, which may place a center of mass in an open location not occupied by the article 12. Additionally or alternatively, in implementations, the controller 3005 is configured to create a bounding box 3805 around the mask 3800 of the article 12 as shown in
Additionally or alternatively, prior to instructing the at least one drive to move or rotate S3940 the arm toward the outlet end into an adjacent work volume, the method comprises determining 3935 whether the arm holding the article at the hoist height is adjacent a collection bin at an outlet end of the enclosed channel. If the arm is not adjacent the collection bin, the method comprises instructing S3945 the actuator of the terminal gripper to open the gripper to release the at least one of the plurality of deformable laundry articles in the adjacent work volume (e.g., the receiving work volume). The method comprises receiving S3950 a signal from at least one sensor in the receiving work volume of the plurality of sequential work volumes, and determining S3955, based on the received signal, a state comprising at least one of one or more of the plurality of deformable laundry articles are present on the stationary floor, and one or more of the plurality of deformable laundry articles are not present on the stationary floor.
If the controller determines, based on the received signal, that the laundry article is not detected, in implementations, the method comprises receiving S3960 a second signal from another of the at least one sensor. For example, in implementations, the first signal can be at least one of a 2D and 3D image and the second signal can be another at least one of a 2D and 3D image. In implementations, the second signal can be, for example as shown in
The method comprises determining S3962 whether the second signal indicates an article being detected in the receiving work volume. If any article is not detected, the method returns to determining S39390 whether the previous gripper missed the grab or potentially dropped the article prior to entering the receiving (adjacent) work volume. If the article is on the floor of the prior work volume, the method returns to identifying S3915 a grip point, instructing S3920 the gripper to travel to the grip point, and instructing S3925 the previous arm to hoisting the article.
If the article is determined S2962 to be in the receiving work volume, either detected from the signal of a first of the at least one sensor or a second signal of the at least one sensor, the method comprises identifying S3965 a grip point of the laundry article and instructing S3970 a gripper of the arm associated with the receiving work volume (e.g., the “adjacent work volume”) to travel to and grasp the grip point. The method comprising instructing S3975 the arm to raise the article engaged in the gripper to a suspension height and confirm S3980 whether the laundry article is raised. If the article is not detected in the gripper at the hoist height, the method comprises repeating the steps of identifying S3965 a grip point of the laundry article, instructing S3970 a gripper of the arm associated with the receiving work volume to travel to and grasp the grip point, and instructing S3975 the arm to raise the article engaged in the gripper.
The method comprises determining 3980 whether the gripper missed grabbing the grip point. If the gripper missed, the method comprises executing a miss recovery subroutine as previously described. If the gripper did not miss, the method comprises determining 3935 whether the arm holding the article at the hoist height is adjacent a collection bin at an outlet end of the enclosed channel. If the arm is not adjacent the collection bin, the method iteratively repeats S3940-S3980 until the arm holding the article is the arm closes to the outlet orifice and collection bin. The method comprises determining S3985 at least one characteristic of the laundry article 12 and instructing S3990 alignment of a collection bin (e.g., sorting bin) associated with the at least one characteristic within reach of the arm and engage gripper. As described previously with regard to implementations, the collection bin can be one of a plurality of bins disposed on a carousel or load constructor in operable communication with the controller for shuffling bins beneath the channel for receiving separated articles into one or more bins containing articles of matching one or more washing and drying characteristics. The method comprises instructing S3992 the arm to rotate and the gripper to release the article into the collection bin associated with the at least one characteristic. The robot 3000 thus intelligently batches one or more articles into loads for washing and drying with appropriate collective washing and drying cycle parameters (e.g., water temperature, air temperature, cycle durations, agitation speed, etc.).
In implementations, the method comprises receiving a signal indicative of at least one of a weight and an occupied volume of the collection bin receiving the laundry article. The method comprises determining whether the at least one of weight and volume are above a threshold value. If at least one of the weight and volume exceeds a threshold, the method comprises sending S3998 the collection bin to a washing and drying robot 4000 for laundering.
In implementations, the method comprises stopping iterating the grasps, rotations, and releases when each one of the plurality of deformable laundry articles exits the enclosed channel through the outlet orifice as a solitary deformable article. In implementations, the method comprises instructing two or more of the plurality of arms to operate simultaneously within each associated one of the plurality of sequential work volumes. In implementations, the method comprises instructing terminal grippers of two or more of the plurality of arms operating simultaneously to simultaneously grasp at least one of the plurality of deformable articles. In implementations, the method comprises instructing the at least one drive of the arm with an engaged terminal gripper to move the terminal gripper in at least one of alternating side-to-side and alternating up and down motions to shake a grasped deformable article at the hoist height. In implementations, the method comprises receiving a contact sensor signal from at least one contact sensor on a gripping surface of the terminal gripper indicative of none of the plurality of deformable laundry articles being grasped in the terminal gripper at the hoist height. In implementations, the rather than an engaged gripper releasing each article 12 on the floor 3110 of an adjacent work volume 3105 following a hoist, the gripper 3120 of an available arm 3115 in a receiving work volume 3105 can grip an edge of the article 12 (e.g., a lowest hanging point), hoist the gripped edge to the hoist height and the longest engaged gripper can release the article 12.
