ABSTRACT:
A highly reconfigurable end effector employing three digits, each having two pivoting degrees of freedom and a rotational degree of freedom. The digits have an asymmetrical configuration where two of the digits rotate about an offset axis and the third digit about a substantially non-offset axis allowing the digits to reconfigure about a payload. Each digit employs a strong, tendonless digit actuation mechanism for driving the pivoting degrees of freedom. A differential transmission in the digit actuation mechanism, in conjunction with a double parallelogram configuration formed by the moving segments, provides a selective enveloping or parallel vise grip grasping action of the end effector.
