• a pair of opposed rigid unitary swing fingers pivotally mounted to a swing finger actuator mounted on a hand base member attached to said wrist unit,
• the swing finger actuator including a hydraulic cylinder having a piston rod fastened to said hand base member and adapted to cause swing fingers to operate by the sliding movement of the cylinder tube,
• said swing fingers having a U-shaped cross section and being formed from sheet metal by a pressing process,
• a position detecting means for detecting a terminal position of the sliding movement of said actuator cylinder tube including a signal whereby the fully closed position of said swing fingers is indicated by a signal;
• and
• the pivotal connections of said swing fingers being made by chain pin links.
