The invention discloses a five-finger
robot hand driven by pneumatic muscles. The five-finger
robot hand comprises a connecting
flange which is connected to industrial machinery as well as four bent single fingers and one
thumb, which are mounted on the connecting
flange, wherein each bent single finger comprises a bent single finger metacarpal bone, a bent single finger near finger end, a bent single
finger middle finger end and a bent single finger far finger end; joints are hinged through hinges; a bent single finger return
torsion spring is arranged outside the hinge shaft of each hinge ina sleeving mode; one side of the hand back of the bent single finger metacarpal bone is equipped with a bent single finger pneumatic
muscle a, one side of the hand back of the bent single finger nearfinger end is equipped with a bent single finger pneumatic
muscle b, and a bent single finger
muscle tendon c is further tied on the bent single finger near finger end; and the
thumb comprises a
thumb metacarpal bone, a thumb near-finger end and a thumb far finger end. The five-finger
robot hand driven by the pneumatic muscles provided by the invention is the five-finger
robot hand which has an original state as a holding state under a state of not applying drive force; and after the five-finger
robot hand applies drive force, fingers are opened.
