Abstract: A waterproof mechanism, for a robot hand, includes a cover covering at least a part of a main body portion of the robot hand, covering a driving portion, and including an opening; and an extension member protruding from the opening, wherein the driving portion is held so as to be driven with respect to the main body portion, a proximal end portion of the extension member is fixed to the driving portion, a distal end portion of the extension member is fixed to a claw member of the robot hand, a first fixing member that fixes the extension member and the driving portion to each other is covered by the cover, and a second fixing member that fixes the extension member and the claw member to each other is detachably exposed from the cover.

Abstract: A robot hand includes a motor with a rotary shaft, an accommodating member accommodating a distal end of the rotary shaft, a plurality of swing members swinging with respect to the accommodating member due to rotation of the rotary shaft, and a plurality of claw members swinging with the plurality of swing members.

Abstract: A robot hand includes a motor, claws configured to grip a workpiece in accordance with rotation of the motor, an encoder configured to detect a rotational position of the motor, and a control device configured to control a torque of the motor such that the claws grip the workpiece in accordance with the rotational position.

Abstract: The method of assembling a light scanning apparatus is capable of fine-adjusting a scanning angle and resonance frequency of a mirror section. The method comprises: a step of measuring the scanning angle and resonance frequency of the mirror section, with actuating a vibration source, in a state where a substrate holding member is temporarily fixed on a base member; a step of moving the substrate holding member, in the longitudinal direction of a substrate after releasing the temporarily-fixed state of the substrate holding member; a step of fine-adjusting a substrate-holding position by repeating the step of moving the substrate holding member; and a step of fixing the substrate holding member after the substrate-holding position is set.
