  • Publication number: 20230321835
    Abstract: Methods, apparatuses, systems, and computer readable media for tuning a robot system. In a method, sensed positions of a target that is processed by the robot system are collected from a sensor of the robot system during a movement of the robot system at a predetermined velocity and a predetermined accuracy. Robot positions of the robot system are collected from a controller of the robot system during the movement. Robot position estimations are obtained based on the robot positions and the sensed positions, the robot position estimations being associated with a sensor delay of the robot system caused by the sensor. The sensor delay is determined based on the sensed positions and the robot position estimations. Further, embodiments of present disclosure provide apparatuses, systems, and computer readable media for tuning a robot system.

  • Publication number: 20230047834
    Abstract: Systems, devices, and methods for controlling a robot. Some methods include, in response to determining that an object enters a reachable area of the robot, triggering a first sensor to sense a movement of the object; determining first position information of the object based on data received from the first sensor; determining second position information of the object based on second data received from a second sensor; and generating a first prediction of a target position at which the object is operated by the robot. In this way, the robot can complete an operation for the object on the AGV within a limit operation time during which the AGV passes through the reachable area of the robot. Meanwhile, by collecting the sensing data from different sensor groups, a target position at which the object is handled by the robot may be predicted more accurately.
