Before you go stomping on that cockroach, you may want to read this. Alper Bozkurt and his team fron North Carolina State Univerity have been brainstorming on how to rescue people from a building after a natural disaster. A cockroach would not be the first thing that I would think of, but to this group it was. They created a robotic attachment that is inserted into a cockroach.
Why a cockroach? These bugs have a reputation of surviving in almost any environment and also can maneuver their way through any small space. The cockroaches are controlled by a remote control. Once this creepy bug squeezes its way through the rubbish, the cameras attached can find the missing people.
