Abstract: A robot having seven or more degrees of freedom is disclosed. In various embodiments, the robot includes a positioning robot having m degrees of freedom and a manipulator robot having n degrees of freedom coupled to the positioning robot. The robot is configured to be operated in a first mode of operation, in which the positioning robot is controlled to position move the manipulator robot into a position to perform a task and the manipulator robot is controlled independently of the positioning robot to perform the task; and in a second mode of operation, in which at least a subset of the m degrees of freedom of the positioning robot and at least a subset of the n degrees of freedom of the manipulator robot are controlled together, by a single controller, to perform the task.

Abstract: A robotic line kitting system is disclosed. Data indicating for each of a plurality of operating zones comprising a workspace with which the robotic line kitting system is associated a corresponding safety state information is stored. The data is used to dynamically schedule and perform tasks associated with a higher level objective, including by operating the one or more robotic instrumentalities in one or more operating zones, if any, indicated by the data to currently be available to perform tasks using the one or more robotic instrumentalities and by not operating the one or more robotic instrumentalities in one or more operating zones, if any, indicated by the data to not currently be available to perform tasks using the one or more robotic instrumentalities.

Abstract: A robotic system comprising a mobile chassis, a conveyor oriented substantially parallel to a longitudinal axis of the chassis, one or more robotic arms disposed adjacent to the conveyor, and one or more cameras positioned to view at least a portion of a top surface of the conveyor is disclosed. The system uses the mobile chassis, the conveyor, and the robotic arms to load items into a truck or other container, including by using image data generated by the one or more cameras to assess a state of items on the top surface of the conveyor; determine based at least in part on the image data that an additional item is to be added to the top surface of the conveyor; and operate a robotically controlled structure to cause an item to be added to the top surface of the conveyor.

Abstract: A robotic system to control multiple robots to perform a task cooperatively is disclosed. A first robot determines to perform a task cooperatively with a second robot, moves independently to a first grasp position to grasp an object associated with the task, receives an indication that the second robot is prepared to perform the task cooperatively, and moves the object independently of the second robot in a leader mode along a trajectory determined by the first robot. The second robot assists the first robot in performing the task cooperatively, at least in part by moving independently to a second grasp position, grasping the object, and cooperating with the first robot to move the object, at least in part by operating in a follower mode of operation to maintain engagement with the object as the first robot moves the object along the trajectory.

Abstract: A robotic loading/unloading system is disclosed. In various embodiments, sensor data is received via a communication interface. The sensor data is used to determine a position and orientation of an extendable conveyor relative to a robotic loader comprising one or more robotic arms mounted on a robotically controlled rover. The determined position and orientation of the extendable conveyor relative to the robotic loader are used to control one or both of the extendable conveyor and the robotic loader to place the extendable conveyor and robotic loader to position a distal end of the extendable conveyor within reach of the one or more robotic arms at a location within a work area from which one or more pick or placement locations within the work area are within reach of at least one of the one or more robotic arms.
