Problems solved by technology

However, this improvement is not enough to meet the precision requirements of robotic systems such as assembly systems
[0004] From the above it can be seen that there is a lack of efficient methods and devices for robotic systems to move objects to target locations with high precision

Abstract

A method of moving an object to a target position by an industrial robot is provided, wherein the robot comprises at least one arm and an effector unit mounted at the end of said at least one arm. The method comprises: causing the robot to pick the object at a first position by means of the effector unit and move the picked object to a second position; and in response to a deviation between the second position and the target position, causing the robot to correct the deviation by a motion of the effector unit.

Description

Technical field [0001] The embodiments of the present disclosure relate to an industrial robot system, and in particular, to a method, device, and robot system for moving an object to a target position. Background technique [0002] With the development of robotics, automatic processing of picking up objects by industrial robots and moving them to target positions 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. However, the main problem of automatic processing is that the accuracy of the robot cannot meet the requirements of the system. This problem is particularly prominent for assembly robots. For example, this type of system requires very high precision to be assembled, such as <0.05 mm. However, generally speaking, in the overall work space, the absolute accuracy in the robot coordinate system may be 0.5-1.0 mm...
