Vecna Technologies is developing a robot called BEAR (Battlefield Extraction and Retrieval Robot), designed to:

… find, pick up and rescue people in harm’s way, the humanoid BEAR robot can do what humans can’t: Lift heavy loads and carry them long distances. Whether on a battlefield, in a nuclear reactor core, near a toxic chemical spill, or inside a structurally-compromised building after an earthquake, the BEAR can rescue those in need as well as or better than humans can, without risking additional human life.
