Abstract
Robotic hands and finger modules include an underactuated finger with multiple joints including a distal joint, an intermediate joint, and a proximal joint. A brake subsystem in communication with each of the joints selectively locks and unlocks the joints individually. A robotic hand can selectively lock the joints of a finger individually such that one or more joints are locked while one or more joints are unlocked. In addition, the finger module can drive a tendon coupled to the joints to flex the underactuated finger in a manner determined by which of the joints is locked and which of the joints is unlocked. A robotic hand can move an underactuated finger with its distal and proximal joints unlocked until the finger makes contact with an object, and lock the proximal joint, in response to contact made with the object, while the distal joint remains unlocked.
