Petman, which is probably one of the more human-shaped of the humanoid robots around, is being used here to test temperature-regulating camouflage clothing and a gas mask. (The robot's made with Department of Defense funding, after all.) Any human wearing this suit will probably be a little less--lurch-y? lumber-y? gaitless?--than Petman, but it looks like the suit held up through the series of stretches it tries to do. Seriously, it practically does a jumping jack.
