Publication number: 20120132018Abstract: Apparatus comprising a member (6) arranged to revolve about a remote centre of motion (O) and a base link (3) coupled to a mounting fixture (1). A first link (4) and a second link (5) are pivotably coupled to the member at respective distances (L1, L2) from the remote centre of motion (O) and are translatable relative to the base link (3) along a first direction and at a fixed ratio of displacement. The ratio of said respective distances equals said fixed ratio of displacement, enabling the member (6) to revolve about the remote centre of motion. The apparatus is characterised in that it comprises means (7) for generating translational motion of a first element (37) and of a second element (57) along parallel but opposite directions. The means for generating translational motion is provided on the first link (4) and is arranged to provide motion parallel to the first direction.Type: ApplicationFiled: May 12, 2010Publication date: May 31, 2012Inventors: Hsiao-Wei Tang, Hendrik Van Brussel, Jan Peirs, Thierry Janssens
