It’s not ready to be used in the field yet, but the next military robot may be a stretcher bearer:
Killing a soldier removes one enemy from the fray. Wounding him removes three: the victim and the two who have to carry him from the field of battle. That cynical calculation lies behind the design of many weapons that are intended to incapacitate rather than annihilate. But robotics may change the equation.
The Battlefield Extraction-Assist Robot, BEAR for short, is, in the words of Gary Gilbert of the American Army’s Telemedicine and Advanced Technology Research Centre (TATRC), “a highly agile and powerful mobile robot capable of lifting and carrying a combat casualty from a hazardous area across uneven terrain.” On top of that, when it is not saving lives, it can perform difficult, heavy and repetitive tasks, such as the loading and unloading of ammunition.
The current prototype BEAR is a small, tracked vehicle with two hydraulic arms and a set of video cameras that provide a view of its surroundings to its operator across a wireless link. It has been developed by TATRC in collaboration with Vecna Technologies, a company based in Maryland that invented the robot.
