Boston Dynamics is at it again. This time, they’ve created a creepy biped with a natural gait. 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.
There are so many biped bots circulating the web that we tend to overlook them. This one caught our eye this morning due to its interesting ability to change its layout. Named OmniZero.9, this biped can drive on 4 wheels like a car, walk like a biped, and even carry a person. While it certainly doesn’t look like the most comfortable mode of transportation, it looks less awkward than some of the latest “innovations” coming from big names.
Instructables user [alex.v] posted version 3 of his BiPed Robot. This robot is designed to mimic the control and movements of a human’s lower body. It has 12 degrees of freedom and a nice custom framework CNC’d from acryl sheets. The electronics consist of servos controlled by a custom board built around an ATmega8 and 3 ATtiny26s all programmed in assembly. He also has custom desktop software written in VB which allows direct control of the robot and graphs sensor data. His site contains pictures, videos, and design materials.
