Short summary
We propose a novel mechanism synthesis approach for a 1-degree-of-freedom (DOF) rehabilitation robot, based on chord angle descriptor (CAD) and error tolerance expansion, to generate a pool of mechanism solutions from which mathematically and practically optimal solutions can be selected. A design example of a 1-DOF rehabilitation robot for upper-limb training is provided to demonstrate the efficacy of our novel approach.
