Cyber-Roach! Mic-Equipped Bugs

Remote-controlled cyborg cockroaches could one day be among the first responders at disaster scenes to help locate survivors.

A team of researchers at North Carolina State University has created a swarm of cyborg cockroaches, nicknamed "biobots," that are equipped with microphones to pick up sounds and trace them to their sources. The researchers hope the biobots could one day be used in disaster-relief situations to locate survivors.

Each cockroach has a tiny circuit board "backpack" attached to it that researchers can use to control the bug's movement. Some of the biobots have a single microphone that can capture sounds at a disaster scene and send them back to personnel. Others have a series of microphones that can pinpoint the source of a sound and then steer the bug toward it.
