There are certain areas of the International Space Station that most astronauts would rather not visit—like the exterior. But sometimes, somebody has to clamber around out there, looking for hull cracks. That's when the ISS calls on Russia's SAR-400 telepresence assist-droid.
The SAR-400 is the Russian Space Agency's answer to the recently-launched Robonaut 2 (and it bears an uncanny resemblance to the US drone's design). Designed and built by the Scientific Production Association-Androidnye Technology, and the Central Research Institute of Machine Building, the SAR-400 has been in production and testing at Star City since 2005.
