1. A robot hand for gripping and operating a pipette, the robot hand comprising:
an electric gripper including a motor that controls movement of the robot hand;
a pair of first finger members opened and closed by the electric gripper;
a pair of second finger members provided on the first finger member and having a pipette gripping surface; and
an operating mechanism installed on the first finger member to operate an operation target of the pipette;
the operating mechanism includes an actuator and an operation member driven by the actuator;
the operation member protrudes from the first finger member to a side on which the pipette is gripped, and is movable in a longitudinal direction of the pipette by the actuator;
the operation member has a first protrusion on a surface of the pipette facing the operation target; and
the second finger member has such a thickness that, when the pipette is gripped, the operation target of the pipette is equal to a position of the first protrusion of the operation member.
