Abstract
A parallel kinematics mechanism is provided for uses such as robotics or machining. The mechanism has various limbs, at least some of which are actuatable, for moving an end component with multiple degrees of freedom. The mechanism advantageously facilitates a closed-form solution for the forward kinematics. A joint assembly is provided for use in the parallel kinematics mechanism, the joint assembly having a plurality of revolute joints for connecting to at least three limbs, the joints having non-parallel axes, which intersect at a common point. In various embodiments of the invention, the end component has three, four, five and six degrees of freedom.
