Sweet. Mark Rutherford explains:

The humanoid BEAR (Battlefield Extraction-Assist Robot) can locate victims in a mine shaft, battlefield, toxic spill, or earthquake-damaged structure. And then it can lift them up and then carry them over long distances to safety, according to the manufacturer Vecna Robotics. And it does this without risking any more lives (PDF). The challenge was to enhance search and rescue while reducing the time military, police, and emergency response personnel have to risk their lives each day. More than half of the Medals of Honor earned by medics are awarded posthumously, according to Vecna.
