Of PETMAN – their frankly terrifying robo-humanoid, developed with funding from the US Defense Department’s Chemical and Biological Defense program, Boston Dynamics sez:
It is used to test the performance of protective clothing designed for hazardous environments. The video shows initial testing in a chemical protection suit and gas mask. PETMAN has sensors embedded in its skin that detect any chemicals leaking through the suit. The skin also maintains a micro-climate inside the clothing by sweating and regulating temperature.
Killing all humans: it’s a sweaty business.
