The SULU includes a plurality of articulation linksoperably connectedto the tool assembly by non-rigid links. The articulation links releasablyengage articulationlinks positioned in the central body. The body articulation links areconnected to anarticulation actuator supported for omni-directional movement to effectarticulation of the toolassembly about the first and second axes.
