Sounds like science fiction, but take a look in this older post. Let me remind you as a side note that scientists have already come up with a way to guide a cockroach by implanting electrodes into their antennas and sending appropriate electrical signals. The roach interprets these signals as "obstacles" and... turns...
Dr Alper Bozkurt and Matt Shipman, researchers at the North Carolina State University, used a similar circuit to guide a living cockroach... making an insectobot. The researchers use sound-guided systems to guide the poor insect:
In a collapsed building, sound is the best way to find survivors, 1D says Dr.AlperBozkurt, an assistant professor of electrical and computer engineering at NC State and senior author of two papers on the work.The biobots are equipped with electronic backpacks that control the cockroach 19s movements. Bozkurt 19s research team has created two types of customized backpacks using microphones. One type of biobot has a single microphone that can capture relatively high-resolution sound from any direction to be wirelessly transmitted to first responders.
