SpiderBot Walks on the Ceiling by Shooting Retractable Suction Cups

The robotics lab at Ben Gurion University in Israel has created a robot that walks on the ceiling. SpiderBot has suction cups tethered to the ends of its four legs.  It aims a leg at a spot on the ceiling, then shoots the cup at it.  Then it reels itself toward the spot, releases a rear leg’s suction cup, and slowly repeats the process.  Video at the link.
