Dextre, also known as the Special Purpose Dexterous Manipulator (SPDM), is a two armed robot, or telemanipulator, which is part of the Mobile Servicing System on the International Space Station (ISS), and does repairs otherwise requiring spacewalks. It was launched March 11, 2008 on mission STS-123. Dextre is part of Canada’s contribution to the ISS and is named to represent its dexterous nature. Dextre is the third Canadian robotic arm used on the ISS, preceded by the Space Shuttle’s Canadarm and the large Canadarm2.
