Abstract

A method of moving an object to a target position by an industrial robot is provided, wherein the robot includes at least one arm and an actuator unit mounted at an end of the at least one arm. The method includes causing the robot to pick up an object at a first location via an actuator unit and moving the picked object to a second location; and causing the robot to pass through the actuator unit in response to a deviation between the second location and a target location. Motion correction bias.

Description

technical field [0001] Embodiments of the present disclosure relate to industrial robotic systems, and in particular, to methods, devices, and robotic systems for moving objects to target locations. Background technique [0002] With the development of robotics, automatic handling by picking up objects and moving them to target locations by industrial robots is widely used in various scenarios. The robot picks up the object at the first station and moves it to the second station for subsequent actions, such as placing it on a conveyor or performing assembly tasks, etc. However, the main problem with automatic processing is that the precision of the robot cannot meet the requirements of the system. This problem is especially prominent for assembly robots. For example, this type of system requires very high precision to assemble, eg <0.05mm. However, generally speaking, the absolute accuracy in the robot coordinate system may be 0.5-1.0 mm in the overall workspace, which...
