Abstract
A robot arm includes a robot hand including a hand base to which first and second finger connection portions are connected, and a finger moving portion to move the first and second finger connection portions with respect to the hand base such that a distance between a first finger and a third finger increases or decreases. A rotation axis rotating the hand base passes through a midpoint between fingertips of the first finger and the third finger while the first finger and the third finger are perpendicular to the hand base. the robot arm includes a forearm and a wrist joint to connect the robot hand to the forearm rotatably with two rotational degrees of freedom or one rotational degree of freedom. The forearm is rotatable around a forearm rotation axis that passes through the forearm and is the rotation axis that allows the hand base to be rotated.
