Abstract: The robot system for which the position of a camera attached to the arm is changeable to multiple positions. The robot system memorizes offset information between the arm and the camera for each of multiple positions. Further, the robot system moves the arm to the position offset by the offset information corresponding to the attachment position of the selected camera. As a result, even when the mounting position of the camera is changed, the robot system can move the camera to an appropriate position when imaging and perform imaging without requiring troublesome teaching.

Abstract: In a work machine which includes a working head including a lifting and lowering unit including a working device and a first lifting and lowering device which lifts and lowers the working device, and a second lifting and lowering device which lifts and lowers the lifting and lowering unit, a positional deviation (?x, ?y) of the working device in a direction which is perpendicular to a lifting and lowering direction is eliminated. Since the positional deviation is caused by both an inclination of a lifting and lowering axis line L1 of the working device by the first lifting and lowering device and an inclination of a lifting and lowering axis line L2 of the lifting and lowering unit by the second lifting and lowering device, based on positional deviation data a target moving position is corrected.
