Robotic grasping device with multi-force sensing at base of fingers

Abstract

A robotic grasping device (10) has a first finger (20), a second finger (30) and an actuator (40). The first finger has a first fingertip (22), a first base (24) and a first actuator engagement end (26). A first gripping surface (21) of the first finger lies between the first fingertip and the first base. Similarly, the second finger has a second fingertip (32), a second base (34), a second actuator engagement end (36). A second gripping surface (31) of the second finger is between the second fingertip and the second base. The actuator (40) mechanically engages with the first actuator engagement end and the second actuator engagement end to open and close the fingers. A first force sensor (28) is disposed on the base of the first finger to measure a first operative force on the first finger, and a second force sensor (38) is disposed on the base of the second finger to measure a second operative force on the second finger.
