We have covered plenty of cool robot from MIT in the past. Its new backflipping Mini Cheetah is pretty cool though. It is a 4-legged robot that can do a backflip. It weighs only 20 pounds and can bend & swing its legs wide to walk right side up or upside down.
The Mini Cheetah Robot can maintain its balance or get back up when kicked. It is nimble and dynamic enough to negotiate rough terrain.
