A robot hand comprising:
- a plurality of fingers;
- a first electromagnet;
- a second electromagnet facing the first electromagnet;
- and
- a movable part made of a magnetic material and configured to be movable between the first electromagnet and the second electromagnet,
- the plurality of fingers including:
- respective gripping parts located at tips of the fingers and configured to grip an object;
- and
- respective rotating parts configured to rotate around rotating shafts in accordance with movement of the movable part,
- the respective gripping parts of the plurality of fingers being configured to perform:
- a closing operation in which the rotating parts rotate in a first direction in accordance with movement of the movable part toward the first electromagnet with magnetic attraction of the first electromagnet, so that the gripping parts move closer to each other;
- and
- an opening operation in which the rotating parts rotate in a second direction opposite to the first direction in accordance with movement of the movable part toward the second electromagnet with magnetic attraction of the second electromagnet, so that the gripping parts move away from each other.
