Petman is a full-size humanoid that can walk, squat, and do push-ups. It was developed to test chemical-resistant military gear and is in no way intended to become a robotic super soldier of the future.

Petman can alter its body temperature and humidity, and even sweat on demand.
Petman was designed by a team led by Marc Raibert at Boston Dynamics. Development started in 2008 with a US $26.3 million U.S. Army program. In 2009, the company, based in Waltham, Mass., first demonstrated Petman's legs by putting them to walk on a treadmill. In 2011, the company showed that the robot legs could run at up to 7 kilometers per hour (about 4.4 miles per hour) and announced it had completed a prototype of the body. Later that year, it unveiled a complete Petman that could walk, squat, kneel, and even do push-ups. The Army funded the development of Petman, short for Protection Ensemble Test Mannequin, to use the robot to test chemical suits and other protective gear used by troops.
