A robot comprising a hand that comprises a finger, the finger comprising:

• a phalanx portion comprising two phalanxes rotatably coupled to each other, one of the two phalanxes being rotatable about a rotation axis with respect to the other one of the two phalanxes;
• and
• a stopper structure comprising a first stopper member connected to the one of the two phalanxes and a second stopper member connected to the other one of the two phalanxes, the first stopper member extending around the rotation axis, a circumferential space being defined between the first stopper member and the second stopper member and allowing the first stopper member to rotate together with the one of the two phalanxes in a predetermined range,
• wherein the finger further comprises a rope and a transmission assembly, the rope being connected to the one of the phalanxes and the transmission assembly, and the transmission assembly being configured to Dull the rope to move so as to enable the rope to pull the one of the phalanxes to rotate.
