Boston Dynamics created a creepy biped with a natural gait. The Biped robot that balances dynamically using a human-like walking motion. It is a close relative to BigDog, sharing elements of the mechanical design and control.
It may look very similar to BigDog, because it really is almost the same system. Named PETMAN, this biped system is being designed to help test chemical protection suits.
This bot can stress the suit by walking, running, and even crawling in a room filled with poison gas. Not only can PETMAN walk, run, and crawl, but it can also sweat and change its temperature. That’s pretty cool. Like BigDog, the most impressive part is when they give it a shove and it recovers with a motion that seems almost organic.
