Abstract:
A controlled relative motion system permitting a controlled motion member, joined to another base member, to selectively move with respect to that base member, said system comprising:a base support; a manipulable support; a group of at least four link end constrainers each having a first portion movably connected to a second portion thereof such that ends of said first and second portions can be selectively separated from one another along a selected direction so as to have a selected distance therebetween; a first group of at least four pivoting links each rotatably coupled to said base support so as to be rotatable about a corresponding base link axis and each coupled to a said first portion end of a corresponding one of said group of link end constrainers; and a second group of at least four pivoting links each rotatably coupled to said manipulable support so as to be rotatable about a corresponding support link axis and each coupled to a said second portion end of a corresponding one of said group of link end constrainers.
