Abstract
A finger unit of a robot hand has a first rotational actuator, a first finger joint part, a first finger linkage, a second finger joint part, and a second finger linkage that are connected in this order. A second rotational actuator is attached to the first finger linkage. The first finger linkage swivels about the first finger joint part by the first rotational actuator, and the second finger linkage swivels about the second finger joint part by the second rotational actuator. The second rotational actuator is attached to the first finger linkage so as to be in a slantwise orientation relative to a straight line connecting a center of rotation of the first finger joint part and a center of rotation of the second finger joint part. With this configuration, an axial length of the finger unit of a robot hand can be shortened.
