In some embodiments, since it is possible that part of the components could partially concealed from the QA system (or only partially visible), the Deep Learning (D/L) algorithms of the system uses previously learned process to identify the parts and estimate their location.
In some embodiments, the D/L algorithms are used to predict a possible error in the routing system, for example, if a ground wire typically goes to port A in certain connectors but in one instruction-set a ground wire is (mistakenly) routed to port B—the system provides a warning or alternatively use other logic to see if port B can also accept the ground wire.
In some embodiments, the automated wiring systems utilizes reinforced learning for flexible wire insertion with impedance control, which potentially increases the insertion of wires in their correct location.

Before explaining at least one embodiment of an exemplary wiring arms module 206 and an exemplary wiring end-effector module 208 of the invention in detail, the inventors would like to convey one of the many possible challenges in the robotic automation performance in general, and specifically, in the robotic automation for electrical wiring and robotic wiring manipulation. The inventors have found that in order to perform correct wiring of electrical wires into an electrical cabinet a certain level of dexterity and/or sensibility (meaning high levels of wire manipulation capabilities) is required and, apparently, in some instances, at least two hands. For example, a technician and/or a user, utilizing his somatosensory system (for example: touch), needs to hold the wire with one hand, insert the wire as is or the wire with a wire head in the electrical socket or electrical terminal connector of a component, and with the other hand perform the locking actions to lock the wire in the socket. The terms “electrical socket” and “electrical terminal connector” are interchangeable and should either of them be mentioned, it should be understood that either refer to the same thing, which is an object in a component configured to receive a wire for purposes of connecting and/or holding an electrical wire to the component. Furthermore, depending on the type of wire end, the user must use just the necessary force when inserting the wire into the socket for, on one side, inserting and keeping the wire in the socket while it is being locked and, on the other side, avoiding deformation of the wire due to the application of excessive force. It is also common in the art for the user to “feel” that the wire is secured in location by slightingly pulling it after the locking action has been performed. In the following paragraphs exemplary actions performed by a human will be described to allow a person having skills in the art to understand the challenges when translating apparent easy tasks performed by humans into robotics.
In some embodiments, the robotic systems comprise fine motor skills (or dexterity). In some embodiments, the automated wiring system (in general) and the wiring arms modules of the present invention comprises one or more of the following technical characteristics:

In some embodiments, this allows a higher variability in gripping force control. In some embodiments, the software comprises information regarding payload weights/stiffness and structure and program that enhances the correct function (grasp planning) of the grippers without overshoot.
In some embodiments, parts of the arms and or grippers may be automatically changed for specific tasks for example to hold different tools such as tweezers or cutters.

In some embodiments, these actions are performed using capabilities that are referred herein as Grip and Slip capabilities.

In some embodiments the wiring-end effector module 300 includes one or more optical sensors, for example, one or more cameras and/or lasers scanners. In some embodiments, the wiring-end effector module 300 includes multiple 2D and/or 3D cameras.

In some embodiments, electrical mechanism 912 includes sensors that can measure moments that are applied by the elongated extensions 910a-b during insertion, for example moments at a value of from about 0.01NM to about 0.1NM.
Referring now to FIGS. 9C2-9C3, showing schematic representations of exemplary gimbal blocks to which the extensions are connected, according to some embodiments of the invention. In some embodiments, the gimbal block 970 comprises a plurality of parts that allow the monitoring of forces applied on the extensions 910a-b. In some embodiments, the plurality of parts are one or more gimbals mounted on top of each other but having different axis of movement. In order to facilitate the explanations, two axis of movement will be described. It should be understood that more gimbals can be use, thereby providing more than two axis of movement that can be monitored. These are also part of the scope of the invention. Returning to FIG. 9C2, the gimbal block 970 comprises a top block 972, which connects the gimbal block 970 to the rest of the device. In some embodiments, below the top block 972 there is a top connector 974, which is connected to the top block 972 by means, for example, of screws 976. In some embodiments, one or more damping springs 996 in communication with one or more Button Axis Load Cells 978 are housed between the top block 972 and the top connector 974. In some embodiments, calibration of the Load Cells is performed by actuating the Damping Force Calibrating set screw 980. In some embodiments, below the top connector 974 there is a center block 982. In some embodiments, inserted in the top side of center block 982 there is a first gimbal axis 984, which confers the axis of movement perpendicular to the pin of the first gimbal axis 984 in the horizontal direction (see below explanations about the movement of the gimbal block). In some embodiments, inserted on the bottom side of the center block 982 there is a second gimbal axis 986 (shown in an inserted position). In some embodiments, the second gimbal axis 986 is perpendicular to the first gimbal axis 984. In some embodiments, the second gimbal axis 986 confers the axis of movement perpendicular to the pin of the second gimbal axis 986 in the horizontal direction (see below explanations about the movement of the gimbal block). In some embodiments, below the center block 982, there is a bottom connector 988, which is connected on the top to the center block 982 and on the bottom to a bottom block 990. In some embodiments, not shown in FIG. 9C2, another set of one or more damping springs in relation/interface with another set of one or more Button Axis Load Cells are housed between the bottom connector 988 and the bottom block 990. In some embodiments, the extensions 910a-b are connected to the bottom block 990.
In some embodiments, the device comprises one gimbal block 970 to which both extensions 910a-b are connected. In some embodiments, the device comprises two gimbal blocks 970, one gimbal block 970 for each extension, as shown for example in FIG. 9C3.
Referring now to FIG. 9C3, showing schematic representation of the exemplary movements of the gimbal block 970 and an exemplary embodiment of a device comprising two gimbal blocks, according to some embodiments of the invention. In some embodiments, as mentioned above, the gimbal block 970 comprises a first gimbal axis 984, which provides the gimbal block 970 movement in a first axis, and a second gimbal axis 986, which provides the gimbal block 970 movement in a second axis. In FIG. 9C3, a side view of the gimbal block 970 is shown, showing the movement (arrow 992) enabled by the first gimbal axis 984. Additionally, in FIG. 9C3, a front view of the gimbal block 970 is shown, showing the movement (arrow 994) enabled by the second gimbal axis 386. In some embodiments, the first gimbal axis 984 and the second gimbal axis 986 provide the gimbal block 970 with dual rotational axes at different locations. In some embodiments, these rotational axes are used with the single axis load cell to measure moments and force applied on the extensions. In some embodiments, as shown in FIG. 9C3, the two extensions are each separately connected to a gimbal block 970, therefore allowing measurement of different forces on each extension. In some embodiments, when the gimbal mechanisms reach their limit of rotation (movement), which optionally implies an access of force applied on an extension (for example during a possible collision of the device with the electrical panel), the system may halt the insertion operation of the wire and/or take corrective actions (moving the device).

In some embodiments, the wire locking element 904 comprises a torque sensor configured to monitor the torque forces applied by the actuator on the locking mechanism of the electrical terminal connector in the component. In some embodiments, the system comprises a database where specific torque forces related to specific locking mechanisms of electrical terminal connectors are saved. In some embodiments, the system comprises instructions to actuate the actuator according to specific parameters which specifically match the torque requirements of specific locking mechanism of specific electrical terminal connectors and specific wire gauge.
Referring now to FIGS. 9E2-9E3, showing schematic representation of ferrules, according to some embodiments of the invention. In some embodiments, the wires used in the automatic wiring system are wires that comprise a built-in ferrule at the distal end (ferrule wire head). Ferrules are a ring or cap 9002, optionally having a metal distal end 9004, used to enclose the distal end of the exposed wire in order to facilitate the handling and connection of the distal end of the wire into the electrical terminal connector of the component. In some embodiments, the ferrule is stiff. In some embodiments, the ferrule is stiffer than the wire itself. In some embodiments, the ferrule is between about 2 and about 10 times stiffer than the wire. In some embodiments, ferrules can have different dimensions, as shown for example in FIG. 9E2. In some embodiments, the ferrules can have a different form of the metal part 9004 at the distal end, as shown for example in FIG. 9E3. In some embodiments, since the ferrule comprises the cap 9002, which is stiffer than the wire itself, the wiring-end effector module 208 pinches the cap 9002 instead of directly pinching the wire. In some embodiments, a potential advantage of pinching the cap 9002 is that it eases the manipulation of the wire during the insertion into the electrical terminal connector of the component. Since the wire is pliant, it can happen that the wire bends during the insertion causing a deviation in the directionality of the head of the wire that needs to be inserted in the electrical terminal connector. Pinching the cap 9002 potentially helps avoiding this. In some embodiments, ferrules are configured to be completely inserted into the electrical terminal connectors of the components, meaning that the cap 9002 needs to be completely inserted inside the electrical terminal connector of the component in order to be correctly connected. In some embodiments, during the use of wires with ferrules, the method of insertion of the wire into the electrical terminal connector of the component comprises additional steps, as will be further disclosed below. In some embodiments, the additional actions needed to be performed during the insertion of a wire including a ferrule include one or more of: the partial insertion of the ferrule into the electrical terminal connector of the component, release or partial release of the ferrule, moving backwards of the device, re-pinching the wire at a distal location in the wire in relation to the ferrule, finishing the insertion of the wire and ferrule in the electrical terminal connector of the component. In some embodiments, before the release of the ferrule, the system optionally partially closes the locking mechanism of the electrical terminal connector in the component to partially hold the ferrule in place and potentially avoid the ferrule from exiting the electrical terminal connector. In some embodiments, in this case, after re-pinching the wire and before further inserting the wire in the electrical terminal connector, the system releases the locking mechanism of electrical terminal connector to allow further insertion of the wire into the electrical terminal connector. In some embodiments, the wiring-end effector module 300 comprises an additional element configured to hold the wire in place while the extensions are moved to a more distal position on the wire. In some embodiments, the additional element can be a third extension configured to be extended when needed and to hold in place the wire.
In some embodiment the extensions/end effector can insert ferrules of complex shape such as fork type ferrule or ring type ferrule into the connector.

In some embodiments, the parameters sensed by the one or more sensors, either in the extensions, on the gimbal block or anywhere else in the system, for example force, thresholds, motion values relating to the wire and the insertion process are saved in a data base.
In some embodiments, when a wire is held by two wiring arm modules, the system comprises instructions to hold the wire in a certain way. For example, the wire is held in a certain position relative to the electrical cabinet. Another example a wire is held with a certain tension between the two points on the wire that are being held by the two arms. In some embodiments, a series of instructions are prepared and provided to each of the arm modules during the wiring planning process. In some embodiments, this is performed to allow the robotic arms to act potentially without causing damages to each other, without causing damages to the electrical cabinet, without causing damage to the wire and/or without causing tangling of the wire during the wiring process. In some embodiments, the tension on the wire is directional. For example, while one mechanical arm holds the wire on one end, the other mechanical arm holds the other end while keeping tension and in the direction of the location where it will be allocated in the electrical cabinet, optionally above the duct/DIN.
In some embodiments, the role of holding and tensing the wire is interchangeable between the two mechanical arms. For example, at the beginning of a wiring action, a first mechanical arm holds the wire and does not move, while a second mechanical moves while sliding the wire towards the location where the wire will be allocated. Once the second arm arrives at the destined location on the electrical cabinet it stops, the first arm then releases the wire and goes to where the second mechanical arm is located to continue the wiring process. At this point the second mechanical arm is the one holding the wire while not moving, while the first one will be the one sliding the wire and moving it towards the location in the electrical cabinet where it will be positioned.
In some embodiments, during the wiring process, one of the two arms slides over the wire when laying it on a duct/DIN. For example, as explained above when describing when the wiring-end effector module 208 reduces the radial force on the wire and allows the wire to slip while the mechanical arm moves (see
In some embodiments, the distance between the two wiring arms is maintained. In some embodiments, optionally, the distance is adjusted during the placing of a cable in relation to the route of the cable in the duct(s). In some embodiments, optionally, the distance between the arms provide clearance from the components located on the board. In some embodiments, the motion of the arms is slowed down or stopped if the tension is above certain threshold, for example, 15% more than the desired tension and/or the predetermined threshold. In some embodiments, thresholds are set according to the wiring arm capabilities, the type of wire and any combination thereof. In some embodiments, the system monitors the distance between the arms and keeps a certain distance between the wiring arms. In some embodiments, if the distance between the arms exceeds a certain predetermined distance, the motion of the arms is adjusted or stopped.
In some embodiments, when the system senses that a level of tension in the wire and/or a distance between the arms is out of tolerance and/or above or below a predetermined value, for example, ±20% of the predetermined value/tolerance value, the wiring end effector releases the wire to avoid possible damage to the arms and/or the panel/component.
In some embodiments, before placing the wire in a duct, a vision system is used to validate the process.
In some embodiments, operation of two wiring arms for the wiring of a cabinet requires high levels of synchronization and precision in the operation of the arms in a plurality of levels, for example (not an exhaustive list), the operation of one arm with respect to the other, operation of the arms with respect to the cabinet, operation of the arm with respect to the wire, operation of the arms with respect to the wire and the wiring routing plan of the wire in the panel.
In some embodiments, an example of dual arm coordination during wire routing operation comprises that during the routing a first arm will lead the way, meaning the arm that will insert the end of the wire to the relevant terminal connector in the component, while a second arm will follow and support the first arm during the routing process. In some embodiments, a lead wiring arm can become a support arm during the wiring process, and vice versa. In some embodiments, during the wiring process the support arm keeps the wire at certain tension in relation to the lead wire arm by maintaining a certain force on the wire (e.g. 2N, 4N, 8N). In some embodiments, during the wiring process the support arm keeps part of the wire in tension, for example the part of the wire held between the two wiring arms, while other part is left without tension (the wire slacks and/or dangles behind the wiring-end effector). In some embodiments, the length of the slack is from about 10% to about 30% of the total length of the wire being wired. Optionally from about 5% to about 40% of the total length of the wire being wired. Optionally from about 1% to about 50% of the total length of the wire being wired. For example 15%, 20% or 25% of the total length of the wire being wired). In some embodiments, during the wiring process, the slacked wire is held above (when the wiring is performed from above on a panel arranged in an horizontal direction, see for example
In some embodiments, the wiring process comprises inserting a first end of a wire into a terminal connector in a component in the cabinet and then taking the cable along a planned path inside the cabinet, towards a second component inside the cabinet where the other end of the wire will be connected to a second terminal connector in the second component. In some embodiments, once the first end of the wire has been inserted into the first component, for example, by the first arm, then the second arm will become the leading arm, taking the wire towards the second component, while the first arm will become the support arm.
In some embodiments, the support arm performs one or more of the following actions: securing the wire in the duct (optionally with other tools, for example a passive finger a stapler, a gluer and/or a latching element; or may be used to place a plastic holding strip (“a bridge”) clearing the way to the leading arm; validating routing process using one or more sensors, for example, a camera, a force sensor, a laser line sensor and/or a proximity sensor). In some embodiments, a safe zone is defined, for example, above component level (when the wiring is performed from above on a panel arranged in an horizontal direction, see for example
In some embodiment where multiple wires are placed in same duct, the position of the manipulated wire that is being held, is in relation to the already placed wire, for example, if the center of the duct is occupied by other wires, the support arm will place and/or will nudge the wire being currently placed to one side of the duct. In some embodiments, the software takes into account the load on the ducts and can, optionally, add to the wire length to compensate for added distance required due to wire loads in the ducts, for example adding 1%, 2% or 5% to wire length.
In some embodiments, the system comprises one or more features configured to optimize the automated wiring process performed by an exemplary horizontal/vertical automated wiring system.
In some embodiments, as explained above, while the lead wiring arm is positioning the wire along the planned path in the cabinet, the support wiring arm provides support to the actions performed by the lead wiring arm. In some embodiments, one of those support actions is to hold the rest of the wire that the lead wiring arm is “dragging” while moving the end of the wire through the wiring path. In some embodiments, the wiring arms optionally comprise a dedicated cartridge where lose wire is rolled and/or kept, when a specific wire arm acts as support wiring arm. In some embodiments, since the roles of lead and support might change during the wiring process, both arm optionally comprise the dedicated cartridge. In some embodiments, the wire that is kept in the dedicated cartridge is released when necessary during the wiring process, for example, when a motion of an arm requires more lose wire, while considering ducts and/or obstacles in wiring path. In some embodiments, a potential advantage of having the dedicated cartridge is that long wires are kept contained during the wiring process thereby potentially avoiding the lose wire to cause damage or get entangled during the wiring process.
In some embodiments, if and when during a wiring process, there is a possibility that the wire, being positioned in the cabinet by the lead wiring arm, might get entangled and/or could not be correctly positioned in the destined place along the path, the system is configured to activate the support wiring arm to perform actions to solve these problems. For example, the support wiring arm will move the obstacle (for example other wires already positioned in the cabinet) away from the wire being positioned, optionally using a dedicated tool that allows interaction with other wires without damaging them (for example a tweezer, an elongated rod). In some embodiments, optionally, during the clearing of obstructions, the support wiring arm does not hold the wire being positioned. In some embodiments, optionally, the wire is routed with the two arms around an obstacle. In some embodiments, alternatively, a new path is calculated to provide a detour around the obstacle.
Use of One Wiring Arm when Possible
In some embodiments, the system is not obligated to use two wiring arms for the wiring process. In some embodiments, for example when wiring short wires (e.g. having 1 cm, 2 cm, 5 cm length), the system is configured to allow one wiring arm to do the whole wiring process, leaving the second arm to perform other tasks related to the overall wiring process of the cabinet. In some embodiments, optionally for a short wire, the wiring arm secures one end of the wire in the object/component and then slides along the wire (while possibly “feeling” the sliding motion) to the other end and then insert it in the required position. In some embodiments, optionally, after the 1st insertion, the arm releases the wire and re-grabs it at the other end optionally with aid of sensors for example a vision camera.
In some embodiments, the system utilizes its ‘grip and slip’ capabilities for the allocation of the wires on the planned path. For example, wiring arm can hold the wire on top of the surface where it is needed to be positioned, and slowly moving along the wire (the ‘slip’ component of the ‘grip and slip’ capabilities) while positioning the wire in the destined path.
In some embodiments, the wire end effectors are configured to actuate, for example, moving upwards/downwards and/or pushing, circuit breakers in the panel. In some embodiments, the actuation is perform using the extensions. In some embodiments, actuation is performed using a dedicated actuation device. In some embodiments upon switching on/off a component certain tests are performed, for example, continuity test, load test, logical test (of circuit logic).
In some embodiments, the system is configured to manipulate not only single wire wires, but also wires comprising one or more splits in the wire, providing a multi-wire wire and/or harnesses. In some embodiments, for example, wires with a T-like harness having three ends, the supporting arm holds the location on the wire where the split in the wire is located while the leading arm inserts one end of the wire to a component and then a second end of the wire to a second component.
In some embodiments, the extensions of the end-effector are configured to hold a wire head that needs to be inserted into a component. For example, a network cable comprises a dedicated wire head (also known as RJ45 connector). In this example, the extensions of the end-effector are configured to hold the RJ45 connector of a network cable and connect it to a dedicated component in the cabinet. In some embodiments, the system comprises information about the sensory feedback that will be recorded when connecting these types of wire heads, for example, force, torque and visual feedback. In some embodiments, sensory feedbacks are used to validate proper insertion of the wire head in place. In some embodiments, after insertion of the wire head in place, the locking actuator is used to secure the wire head in place, for example by tightening the screws of the connector in the component. In some embodiments, a dual push action is used (i.e. pushing releasing and re-grabbing) to insert the wire head.
In some embodiments, the system is configured to perform a part of a task, stop, perform a different task, and then pick up the previous task and finish it. For example, connecting one end of a wire to one connector and positioning the wire along the planned path, release the wire, perform different tasks and then return to the wire previously left and continue with the positioning and/or connection to a connector. In some embodiments, re-grabbing a wire is done using vision system and/or by going to a known position (a component a clip a corner) and slipping along the wire to its end.
In some embodiments, the wire end effectors are provided with multiple degrees of freedom (DOF) to allow overcoming of obstacles and/or wire overcrowding. In some embodiments, the wire end effectors or the manipulating arms are provided with 6 degrees of freedom: three rotations and three translations about each perpendicular axis. In some embodiments, the wire end effectors are provided with 7 or more degrees of freedom. In some embodiments, a potential advantage of providing more than 6 degrees of freedom is that, while it may cause redundancy (or over-redundancy) problems in the software, it may also potentially allow the solving of wire manipulation to overcome obstacles and/or when positioning a wire during a wire overcrowding situation.
In some embodiments, components to be used in an electrical cabinet will comprise a smart identification marker on top of it so it can be read by the automated wiring system during the wiring process. For example, markers along the ducts, which will provide reference for the wiring arms regarding their location along the duct. For example, a specific connector, called connector X for this example, is located at specific coordinates in the electrical cabinet and it comprises a smart identification marker. In some embodiments, the mechanical arm will comprise a reader or a camera or a sensor for the smart identification marker, which will be used to corroborate the correct arrival at the correct location of the mechanical arm.
In some embodiments, the electrical cabinet will be provided with dedicated location markers, which will be added to the information stored in the designing console 102 to be used and identified by the mechanical arms, using for example a camera or a reader, during the wiring process.
In some embodiments, the electrical panel is provided with components which do not comprise connectors comprising screws for locking the wires in place, for example by using self-locking mechanisms.
In some embodiments, the electrical panel is provided with smart ducts, alternatively with smart DIN rail (or both), configured to assist in the automatic wiring process. For example, the ducts may comprise one or more clips and/or holders and/or reversible attachable connectors for the wire, which hold the wire that was placed in them once they are placed. In some embodiments, a potential advantage of this is that it allows already placed wires to not interfere with the rest of the wiring process. In some embodiments, the ducts/DINs comprise one or more location markers, which are also stored in the designing console 102 to be used and identified by the mechanical arms. In some embodiments, the smart ducts/DINs are configured to receive smart wires as explained below. In some embodiments, the electrical panel is configured to allow positioning wires and then positioning an inverted duct on top of the positioned wires so the wires will be covered. In some embodiments, the ducts/DINs are positioned at an angle that helps with the automated wiring by the mechanical arms. For example are positioned at an angle of from about 1 degree to about 15 degrees in relation to the electrical cabinet. In some embodiments, the ducts/DINs comprise tightening strips configured to tighten the wires to the ducts/DINs once in place. In some embodiments, the ducts have side opening in order to provide an easy access for the robot to locate and/or to pass the wire through the side. In some embodiments, the ducts may have marking that will potentially ease the duct alignment/location relative to the rest of the panel, for example it can include scale/color, etc. In some embodiments, the ducts comprise one or more attachments for allowing the wire assembly robot to place them before/during or after placement of the wires. For example, the ducts may have adhesive at the bottom to secure the duct to the panel once placed.
In some embodiment the DIN rail has marking at one or two ends to allow accurate location and identification of a position in the rail relative to the panel. In some embodiments, optionally, at the end of each array of components mounted on the DIN rail, a marking component is added to identify the end and/or a beginning location of the components placed on the DIN rail.
In some embodiments, wires are positioned in a duct-less panel, and, after finishing a part or all of the positioning of the wire, an inverse duct (meaning having an opening on the bottom and it is covered on the top) is positioned on top of the wires, thereby closing the wires in a closed duct.
In some embodiments, the electrical panel is wired with smart wires configured to assist in the automatic wiring process. For example, the wires may comprise one or more clips and/or holders and/or reversible attachable connectors for the wire, which hold the wire in place once installed in the duct/DIN. In some embodiments, a potential advantage of this is that it allows already placed wires to not interfere with the rest of the wiring process. In some embodiments, the wires comprise one or more location markers, which are also stored in the designing console 102 to be used and identified by the mechanical arms during the wiring process. In some embodiments, the wires may comprise a connecting material (for example glue) and once the wires are positioned the connecting material will keep the wire in place optionally the adhesive on the wire can be cured after placement. In some embodiments, the wires comprise a roughed surface to help the elongated member with the grabbing of the wires. In some embodiments, the wires comprise different cross sections that support better arrangement of the wires in the duct, for example a square cross section.
In some embodiments, the electrical cabinet may not comprise ducts at all, for example by providing smart wires that can be attached to one another, and the wires are those who keep the wires in place.

In some embodiments, at this point, the system generates a sequence of routing of wires based on the electrical schematic and the mechanical drawing 1111. In some embodiments, as explained herein elsewhere, the generation of a sequence of routing of wires comprises the virtual generation of a series of possible sequences of inserting the wires in the electrical cabinet, and evaluating possible problems that could occur during the actual wiring of the electrical cabinet. In some embodiments, optionally, the system performs simulations to optimize the sequence of routing the wires, optionally according to determined parameters.
In some embodiments, the abovementioned actions comprises a continuous exchange of data between the computer of the user planning the electrical and the server 1112.

In some embodiments, the exemplary horizontal automated wiring system 1700 comprises another two automated mechanical arms 1718, similar to the mechanical arms as disclosed above. In some embodiments, the wire preparation system 1704 can optionally prepare in advance a plurality of wires, which are left near the two automated mechanical arms 1718. In some embodiments, similar to the other systems, this system optionally comprises a depth camera configured to monitor the wiring actions of the system. In some embodiments, the wiring methods are the same as disclosed herein elsewhere. In some embodiments, each of the two automated mechanical arms 1718 are mounted on a base 1724 that is configured to move horizontally on the base 1702. In some embodiments, the exemplary horizontal automated wiring system 1700 comprises a drawer like panel handling module 1720 that is moved to insert and/or remove the electrical cabinet 1722 before and/or after has been wired, as shown for example in
In some embodiments, in addition to the automated wiring system, the system of the present invention can be configured to mount electrical components into the electrical cabinet prior to the automated wiring process. In some embodiments, a potential advantage of doing this is that all the preparations of the electrical cabinet are performed and monitored at the same location.
In some embodiments, the system comprises one mechanical arm configured to perform all automated action of the wiring process.

As stated above, in the following example a wire needs to be placed between Component A and Component B. For the matters of this example, it was decided that the chosen path from Component A to Component B will be by extending the wire from reference point 1, which is the wire connected to Component A, to reference point 2, into duct 1808-3 following reference point 3. Then the wire will need to be turned to be then extended inside duct 1808-3 towards reference point 4 and into duct 1808-5. Then the wire will need to make a turn into duct 1808-5 towards reference point 5. Then the wire will need to make a turn into duct 1808-4 towards reference point 6. Then the wire will exit duct 1808-4 at reference point 7, and will be inserted into Component B following reference point 8.
The following table summarizes the actions of arm one 1802 and arm two 1804 during the placement of the wire from reference point 1 to reference point 8.

Phase A: movement forward towards the electrical terminal connector of a component. In some embodiments, at this phase, the wire is held by the gripper 1308 and the gripper 1308 is moving forward towards the electrical terminal connector of the component. In some embodiments, at the beginning the sensed force is the same as the wire has not met any obstruction. In some embodiments, at some point, the wire meets the electrical terminal connector of the component, and the sensors begin to sense an increase in the sensed force. Once reached a certain peak, the system will move to the next phase. In some embodiments, the peak may depend and optionally set based on type of wire and/or the type of electrical terminal connector. In some embodiments, the relation between the type of wire, the type of connector of the component and the “sensed” forces is learned by the system and stored in a dedicated database. In some embodiments, an AI algorithm is used to generate these peak values based on learned data.
Phase B: movement backwards from the electrical terminal connector of the component. In some embodiments, once a certain peak has been reached, the gripper 1308 will begin moving backwards while still holding the wire but without actually pulling the wire with it. In some embodiments, as shown in the graph, the sensed forces decrease drastically, as the gripper loosens the grip.
Phase C: movement backwards from the electrical terminal connector of the component while pulling the wire. In some embodiments, in order to assess correct connection between the wire and the electrical terminal connector of the component, the gripper gently holds the wire while continuing moving backwards from the electrical terminal connector of the component. In some embodiments, at this point, two possible things can happen: 1. the wire is correctly connected and will not move causing the gripper to slip over the connected wire; or 2. the wire is not connected correctly and will be pulled out the electrical terminal connector. In some embodiments, as mentioned above, the values are learned and/or adjusted after each attempt.
In some embodiments, different types of electrical terminal connectors and different types of wires will be characterized with different forces, which will be characterized by different forces sensed by the gripper. In some embodiments, the system comprises a database in which the different combinations of different types of electrical terminal connectors and different types of wires are kept, and according to the input provided by the user, the system will actuate the gripper accordingly.

The term “consisting essentially of” means that the composition, method or structure may include additional ingredients, steps and/or parts, but only if the additional ingredients, steps and/or parts do not materially alter the basic and novel characteristics of the claimed composition, method or structure.
As used herein, the singular forms “a”, “an” and “the” include plural references unless the context clearly dictates otherwise. For example, the term “a compound” or “at least one compound” may include a plurality of compounds, including mixtures thereof.
Throughout this application, embodiments of this invention may be presented with reference to a range format. It should be understood that the description in range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the invention. Accordingly, the description of a range should be considered to have specifically disclosed all the possible subranges as well as individual numerical values within that range. For example, description of a range such as “from 1 to 6” should be considered to have specifically disclosed subranges such as “from 1 to 3”, “from 1 to 4”, “from 1 to 5”, “from 2 to 4”, “from 2 to 6”, “from 3 to 6”, etc.; as well as individual numbers within that range, for example, 1, 2, 3, 4, 5, and 6. This applies regardless of the breadth of the range.
Whenever a numerical range is indicated herein (for example “10-15”, “10 to 15”, or any pair of numbers linked by these another such range indication), it is meant to include any number (fractional or integral) within the indicated range limits, including the range limits, unless the context clearly dictates otherwise. The phrases “range/ranging/ranges between” a first indicate number and a second indicate number and “range/ranging/ranges from” a first indicate number “to”, “up to”, “until” or “through” (or another such range-indicating term) a second indicate number are used herein interchangeably and are meant to include the first and second indicated numbers and all the fractional and integral numbers therebetween.
Unless otherwise indicated, numbers used herein and any number ranges based thereon are approximations within the accuracy of reasonable measurement and rounding errors as understood by persons skilled in the art.
It is appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention, which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable subcombination or as suitable in any other described embodiment of the invention. Certain features described in the context of various embodiments are not to be considered essential features of those embodiments, unless the embodiment is inoperative without those elements.
Although the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims.
It is the intent of the applicant(s) that all publications, patents and patent applications referred to in this specification are to be incorporated in their entirety by reference into the specification, as if each individual publication, patent or patent application was specifically and individually noted when referenced that it is to be incorporated herein by reference. In addition, citation or identification of any reference in this application shall not be construed as an admission that such reference is available as prior art to the present invention. To the extent that section headings are used, they should not be construed as necessarily limiting. In addition, any priority document(s) of this application is/are hereby incorporated herein by reference in its/their entirety.
