We’re all a little scared (in the impressed-with-technology sense!) of Robonaut, that robot on the International Space Station that is expected to start using legs to move around in the next few months. Eventually, it could even do repairs on the outside — saving astronauts time and keeping them safer.

This fun timelapse video shows Expedition 42 astronaut Terry Virts taking the robot out from what looks like a suitcase on the wall. After he set up Robonaut, however, the machine ran into a few problems.

“The ground teams deployed software and received telemetry from Robonaut. However, [they] were unable to obtain the commanded leg movement that was planned for the day. Ground teams are assessing a forward plan,” NASA wrote in the last ISS update concerning the robot, in mid-December.

While the astronauts patiently wait, they have been posting a few fun tweets about the robot in recent days. Check out what they’ve been saying below.

I wonder what @AstroRobonaut is thinking, looking at me like that… pic.twitter.com/zhSHvLHtNy — Terry W. Virts (@AstroTerry) December 18, 2014

Unwrapping an early Christmas gift last week. @AstroRobonaut is my favorite action figure. #SpaceVine https://t.co/kNtYDaJI2M — Terry W. Virts (@AstroTerry) December 31, 2014
