A ‘brainless’ robot licking metal
James Pike and his colleagues at the University of Pennsylvania’s Department of Engineering have built a battery-less robot. This robot generates energy using ‘Environmentally Controlled Voltage’ or ECV method. It generates electricity by breaking and forming chemical bonds. As soon as it touches the metal surface, the ECV in it undergoes a process of oxidation of the surrounding air and the free electrons give power to the robot.
According to research published in the research journal “Advanced Intelligent Systems”, this robot can walk in its environment without a computer. Its wheels extend beyond the ECV. It has such a system that it walks on the metal path itself and keeps generating its energy by licking it.
