Abstract: When a substrate is held by a first hand, a servomotor is operated to move each guide to an outer peripheral surface of the substrate. When a tactile sensor detects that each guide abuts on the outer peripheral surface of the substrate, the servomotor adjusts a biasing force by each guide to the outer peripheral surface of the substrate according to the shape of the substrate. Therefore, the grasping force can be adjusted according to the shape of the substrate such as warpage and a thickness of the substrate. As a result, it is possible to prevent the substrate from being damaged during transportation regardless of the shape of the substrate.

The robot control unit changes the gripping force for gripping the substrate placed on the four guides, by controlling the pusher actuator depending on the weight measured by the weight sensor unit.
