Abstract
A pair of five-bar mechanisms having their pivotal axes parallel are each mounted at one end to a base and are interconnected at their other ends by a crankshaft to obtain a manipulator generating three degrees of freedom planar motion of an end-effector. Redundant actuation may be used to generate an unlimited rotation range and an extensible link in the crankshaft may be used to provide adjustable torque capabilities during operation.
