EWWW... REMOTE CONTROLLED COCKROACHES ARE COMING Cockroaches are perhaps not the first creatures you would want scuttling around the place spying on you, but their amazing ability to survive in even the most unlikeliest of places has made them appealing cyborgs. Researchers have attempted to manipulate the movements of the insects by stimulating their antennae, tricking them into thinking they were meeting obstacles and needed to avoid them. More recent research has also used little backpacks, weighing 0.007lbs (3g), for the bugs, implanting electrodes into their nervous systems. With this, scientists were able to control the bug correctly around 60 per cent of the time. In November 2014, researchers at North Carolina State University fitted cockroaches with electrical 'backpacks' complete with tiny microphones to detect the faintest of sounds. The idea is that cyborg cockroaches, or 'biobots', could enter crumpled buildings hit by earthquakes, for example, and help emergency workers find survivors. In this case the 'backpacks' control the robo-roach's movements because they are wired to the insect's cerci - sensory organs that cockroaches usually use to feel if their abdomens brush against something. By electrically stimulating the cerci, cockroaches can be prompted to move in a certain direction. In fact, they have been programmed to seek out sound. One type of 'backpack' is equipped with an array of three directional microphones to detect the direction of the sound and steer the biobot in the right direction towards it.
