Abstract
A robot hand equipped with a function of gently pinching an object may include a single degree of freedom joint for allowing bending or stretching at a connecting portion between a distal phalange section and a middle phalange section. The robot hand may further include a driving mechanism for causing this joint to make a rotating motion within a predetermined angular range. This driving mechanism is constituted by a motor and a speed reducer. The joint and the driving mechanism are configured so that the distal phalange section is rotated relative to the middle phalange section in two directions, namely, an inward direction and an outward direction within the predetermined angular range from a state where the distal phalange section is arranged in a straight line with the middle phalange section.
