Robot system, calibration method in robot system, and position correcting method in robot system

摘要

A robot system includes a robot including a main body and a hand. An imaging device picks up an image of a workpiece held by the hand. Image pick-up control means sends movement information to robot control means to move the workpiece held by the robot to a plurality of positions, controls the imaging device to pick up the image of the workpiece at the plurality of positions, recognizes a registered portion of the workpiece at the plurality of positions, and performs a calibration based on the movement information and based on a result of recognizing the registered portion of the workpiece held by the robot at the plurality of positions. The calibration includes correlating positional information of the image picked up by the imaging device to positional information of the robot.
