Robotic Eyes to Assist Satellite Repairs in Orbit NASA is developing and demonstrating technologies to service and repair satellites in distant orbits. This photo looks closely at one of the tools that could be used for satellite servicing in the future: the Visual Inspection Poseable Invertebrate Robot (VIPIR), a robotic, articulating borescope equipped with a second motorized, zoom-lens camera. via NASA http://ift.tt/1Hp7lwo
