A method and an apparatus for providing six degrees of precision motion. As disclosed herein a parallel kinematic manipulator is formed using six fixed length kinematic supporting links. The kinematic links may include a high-resolution position encoder to provide position feedback information. Movement of the manipulator is affected using six linear thrust mechanisms along two parallel linear slide mechanisms. The combination of a parallel kinematic structure and six linear actuators on two linear slides provides a manipulator capable of six degrees of freedom to position components or instruments with high accuracy, stiffness, and/or repeatability with an exceptionally long travel in one degree of freedom.

A rotational joint of intra-extra rotation for assistance of the movement of intra-extra rotation of a shoulder of a user. The rotational joint features a first circular guide arranged to rotate about a first rotation axis and a second circular guide arranged to rotate about a second rotation axis that is parallel to the first rotation axis. A support element is arranged to support the first and the second circular guides. The first and the second circular guide are pivotally connected by a conical wheel having a third rotation axis perpendicular to the first rotation axes and said conical wheel being pivotally constrained to the support element.

In a parallel link mechanism, a distal end side link hub is coupled to a proximal end side link hub via three link mechanisms such that a posture of the distal end side link hub can be changed. Each link mechanism includes a proximal side end link member, a distal side end link member, and a center link member, and forms a quadric chain link mechanism composed of four revolute pairs. A singular point occurs when a central axis of the proximal or distal end side link hub and a central axis which is a rotation axis of a revolute pair section of the proximal or distal side end link member and the center link member coincide with each other. An axis angle of the center link member is specified such that a posture in which the singular point occurs is avoided.
