Remote Center Compliant Flexure Device

Abstract

An apparatus to control displacement of a body spaced-apart from a surface includes a flexure system having a first flexure member defining a first axis of rotation and a second flexure member defining a second axis of rotation. A body is coupled to the flexure system to move about a plurality of axes. An actuation system is coupled to the flexure system to selectively constrain movement of the body along a subset of the plurality of axes.

         18 . A system to define a relative orientation between a body and a substrate spaced apart from said body, said system comprising:
 a flexure system having a first flexure member defining a first axis of rotation and a second flexure member defining a second axis of rotation, with said body being coupled to said flexure system to rotate about said first and second axes in response to contact with a fluid material compressed between said body and said substrate, said first axis extending transversely to said second axis.
