Russian Robonaut Heading to ISS

Russia is working on its own version of NASA's Robonaut with a machine called SAR-400 that's due to reach the International Space Station by 2014, but there's one important difference between the two — tactile feedback. As with NASA's bot, SAR-400 can perform menial tasks, and during testing last November it was used to tighten screws and open hatches. What's arguably most interesting about SAR-400, though, is that the operator can actually feel what the robot is touching through a special pair of gloves. This is combined with audio and video feedback, which is also relayed to the remote operator through built-in cameras and microphones.
