Abstract
A robot system includes a robot including a main body, an arm and a hand as a movable unit, a control unit, and a storage unit. A teaching position is registered in the storage unit. In advance preparation of the robot installed in a working position, the control unit moves the movable unit based on the control amount registered in the storage unit, and registers in the storage unit reference position data representing a positional relation between a workpiece picked up by the movable unit and the main body or a positional relation between the main body and the movable unit. When the robot is reinstalled and when the robot is relocated, the control unit moves the movable unit based on the control amount, registers a difference between position data and the reference position data in the storage unit, and corrects the teaching position based on the difference.
