  • Publication number: 20240140712
    Abstract: A method and system for obtaining an identifier from an item is disclosed. The method includes autonomously operating a robotic structure having a robotic arm to pick an item using an end effector of the robotic arm along a predetermined path from a source location to a destination location according to a plan. The picked item is moved according to the plan. An active measure is determined to be performed at least in part to obtain an identifier determined to be missing based on information received via the communication interface from one or more sensors. The robotic structure is autonomously operated to place the item at the destination location based at least in part on the plan.

  • Publication number: 20240042613
    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.
