You have GOT to watch this video of tiny quadcopter robots flying in perfect formation. Especially at 1:22 when they do the figure 8. Bananas.

 

 

Georgia Tech researchers studied snakes to build a robot named Scalybot 2. No word on the presumably grim fate of Scalybot 1. Snakes are able to slither into all kinds of tight spaces while expending very little energy. 

 

 

We have no video of the crab-like robot that climbs into your stomach and removes cancer cells with a pincer. But at least now you don't have to throw up all over the place from having seen it.
