See a large robotic arm ‘crawl’ across China’s space station (video)

Footage from China’s space station shows how its large robotic arm can “crawl” along the outside of the spacecraft.

The new video from the Chinese Manned Space Agency (CMSA) shows the space station’s 33.5-foot-long (10.2 meters) robotic arm rising up from behind the Tianhe module and reaching out to find a docking port in the foreground.
