Abstract
A robotic link mechanism comprising a pair of base elements connected by a passive flexible joint, such that flexure of the joint changes the mutual orientation of the base elements. A pair of obliquely truncated cylinders are confined between the base elements such that the obliquely formed end surfaces of the cylinders can rotate in sliding contact with each other, and the other end of each cylinder can rotate in sliding contact with its associated base element. Driving motors are attached to the base elements, each one controlled to rotate the cylinder associated with that base element, such that rotation of at least one of the cylinders causes the base elements to undergo change in their mutual orientation. The mechanism thus has a backbone composed of the passive flexible joint, which is supported and actuated by the oblique truncated cylindrical structure that serves as an active exoskeleton.
