1. A robot hand comprising:
a first proximal end finger having a first protrusion at a distal end of the first proximal end finger;
a first distal end finger connected to the first proximal end finger in a relatively rotatable manner, the first distal end finger having a first cutout allowing the first protrusion to pass;
a second proximal end finger having a second protrusion at a distal end of the second proximal end finger;
a second distal end finger connected to the second proximal end finger in a relatively rotatable manner, the second distal end finger having a second cutout allowing the second protrusion to pass;
an opening and closing drive unit that relatively moves the second proximal end finger with respect to the first proximal end finger;
a first rotation drive unit that relatively rotates the first distal end finger with respect to the first proximal end finger;
a second rotation drive unit that relatively rotates the second distal end finger with respect to the second proximal end finger; and
a controller that actuates the opening and closing drive unit, the first rotation drive unit, and the second rotation drive unit.
