I understand that robots are in a way going to change our lives in the near future but I find the cockroach robot designed by some European scientists a stupid idea. The so-called cockroach robot makes the real cockroach believe that it is one of their kinds. The reason being that the cockroaches have bad sight and they are unable to figure out that the robot is in actual a box on wheels. The robot is covered with cockroach pheromones that put the cockroaches to death when they come near to it. I would better prefer a cockroach spray to do the work rather than instead of wasting my time to place the robot cockroach here and there in different rooms at my home. Via: ubergizmo
