A 330-pound humanoid robot was electronically awakened aboard the International Space Station this week, beginning its life as an astronaut's assistant.
The robot named Robonaut 2, or R2, will help with routine tasks such as holding tools and vacuuming air filters. The robot was sent up on space shuttle Discovery in February, but it wasn't powered up until now.
Check out the video above as R2 gets unpacked.
