The Special Purpose Dexterous Manipulator or "[[Dextre]]" is a smaller two-armed robot that can attach to Canadarm2, the ISS, or the Mobile Base System. The arms and their power tools can handle delicate assembly tasks and change [[orbital replacement unit]] (ORUs) currently handled by astronauts during spacewalks. Although Canadarm2 can move around the station in an "inchworm motion", it is unable to carry anything with it unless Dextre is attached. Testing was done in the space simulation chambers of the Canadian Space Agency's [[David Florida Laboratory]] in [[Ottawa]], Ontario. The manipulator was launched to the station on 11 March 2008 on [[STS-123]].
