Cockroaches have been used earlier for cyborg treatment, wherein their antennae were stimulated. It was seen that stimulating the antennae would just trick the cockroach to think there is some obstacle ahead and change its direction, however its complete nervous system is not under operator’s control.  It was seen that a direct stimulation to the nervous system gave far better results. This is not the first time that a cockroach has been used, scientists have previously attached “Kinetic” to the insect for steering its direction, also in some other study the cockroach was made to survive on its fluid. Cockroaches are small in size and the “robot cockroaches” can be  used to reach places which human or a robot cannot reach. Cyborg cockroaches could someday rescue disaster survivors of the nuclear power plants or collapsed mines. By attaching micro cameras and micro phones the rescuers can even communicate with the survivors who are  trapped beneath the debris. Having said that there are chances that these Cyborg cockroaches might also be used for eavesdropping, so be careful of such an insect if you are engaged in some important discussion!! However as of now researchers have converted the pest into most useful robot.
