Robot, heal thyself: Dextre becomes the first robot to repair itself in space

2014-05-20 - Dextre, the Canadian robotic handyman on board the International Space Station, has done several repair and maintenance jobs to date, as well as the Robotic Refueling Mission technology demonstration, when he became the first robot to refuel a mock satellite in space. The space bot is now poised to claim a first for robotkind: self-repair. This animation shows how Dextre will swap two cameras on Canadarm2 and the mobile base, which together form the three main components of Canada’s Mobile Servicing System. Dextre will start by retrieving a faulty camera located near Canadarm2’s elbow joint. Since the camera is functional, but produces hazy images, Dextre will move it to a less critical location on the mobile base. Dextre will then head over to Japan’s Kibo module to fetch a camera from the module’s transfer airlock —a type of sliding drawer that can be depressurized—where the station’s crew will place it for Dextre to retrieve. Dextre will install the new camera on Canadarm2’s elbow joint, wher
