In disaster areas, it's often way too hard and dangerous to send humans in. Especially in things like collapsed buildings, the spaces may be inaccessible, unaccessible. On that same token, robots are an expensive alternative, that often require a custom implementations. We believe that the best way to map out a compressed, unknown space, is with (drumroll please) modified cockroaches. We have performed surgery on the cockroaches to implant electrodes into their antenae. These electrodes send electrical impulses to the cockroach telling it where to go, and a sensor array attached to the cockroach lets us know about its position. All of this data could eventually be used to map out the space that the cockroach is in.
