Abstract: The present application describes a mechanical hand comprising a plurality of finger assemblies each selectively moveable by a respective finger drive assembly about a finger pivot axis along a finger flexion/extension plane and between a finger open position and a finger closed position; a thumb assembly selectively rotatable by a first thumb drive assembly about a first thumb axis between an opposed position and a non-opposed position with respect to the finger assemblies, and selectively moveable by a second thumb drive assembly about a second thumb axis along a thumb flexion/extension plane and between a thumb open position and a thumb closed position; a controller operatively coupled to the finger and thumb drive assemblies; and a selector operatively coupled to the controller for selecting a desired thumb rotational position or a desired grip to be defined by the finger assemblies and the thumb assembly.
