Like many robots deployed in military applications, robots used for post-disaster search-and-rescue missions will go places humans can't. Most are tasked with gathering and reporting data back to human operators to help them locate victims and avoid dangerous situations. To help human first responders, these robots may be a swarm of small individuals communicating among themselves, such as those built by the Georgia Institute of Technology. Others are larger individual units that look for and help victims, like Survivor Buddy.

The design platforms they're based on often do double duty as surveillance and reconnaissance aides for the military, so they're usually equipped with communications capabilities, cameras, and multiple sensor options. Most of them are remote controlled. Some can be configured for autonomous operation, and others are entirely autonomous.

A different way of making rescue robots friendlier is designing them to look more like people, and making them big and strong enough to lift and carry unconscious disaster victims for long distances without hurting them. One example is the Battlefield Extraction Assist Robot (BEAR) prototype, built by Vecna Robotics and funded by the US Army Medical Research and Materiel Command's Telemedicine and Advanced Technology Research Center.

The BEAR, an all-terrain, search-and-rescue, humanoid robot, can lift and carry up to 500 pounds. It's designed to locate, lift, and rescue people, and it can grasp fragile objects without damaging them. The powerful torso and arms are controlled by hydraulics, and its mobility platform has two independent sets of tracked legs. The robot balances itself on the balls of its ankles, and it can remain upright while balancing on its knees or hips. Aside from search and rescue, it can be used for handling hazardous materials, surveillance and reconnaissance, mine inspection, heavy lifting, and warehouse automation.
