From the Article:  “PETMAN is an anthropomorphic robot developed by Boston Dynamics, the creators of the Big Dog robot. PETNAM looks a freakish killing machine, but the purpose of the PETMAN robot is only to test special clothing used by the U.S. Army. PETMAN balances itself as it walks, squats and does calisthenics. PETMAN even does pushups. Boston Dynamics says simulates human physiology by controlling temperature, humidity and sweating inside the clothing to provide realistic test conditions“.

And those are some damn fine pneumatic gams if I may say.
