These pint-sized Nao robots sure are versatile: they can be programmed to dance, be self-aware and even record and relay technical repair instructions. Researchers from the French National Centre for Scientific Research (CNRS) have given their Nao robot "autobiographical memory." That's a system specifically developed to help the ISS crew pass on their knowledge to the next group. Astronauts typically spend only six months aboard the International Space Station per expedition -- some crew members spend a year on the spacecraft, but they're an exception -- before they're replaced by new people. One of them, for instance, could use the system to record himself doing some very specific repairs on a piece of equipment, so that the next batch can learn from him.
