The Astrobees have been developed and built at NASA's Ames Research Center in Mountain View, California. They use fans to move, can turn on any axis and go forward in any direction in space. Each robot has cameras and sensors for navigation and a robotic arm to handle tasks. They run on battery and can dock at a power station and recharge themselves automatically.

They'll also help researchers carry out experiments, test technologies and study human-robot interaction in space, NASA said. The results could help humans prepare to explore the moon and other planets. Two of the three Astrobees are expected to head to the space station this month.
