ABSTRACT:
In a control method for a power assist apparatus, a pressing force acting on a workpiece held by a workpiece holding apparatus is detected, a determination is made as to whether or not the detected pressing force exceeds a preset threshold, a determination is made as to whether or not a dead man switch provided on the workpiece holding apparatus is ON, and a determination as to whether or not to release a rotation restriction applied to a joint portion for connecting the workpiece holding apparatus rotatably to an arm is made in accordance with a result of the determination as to whether or not the detected pressing force exceeds the preset threshold and a result of the determination as to whether or not the dead mean switch is ON.
