Detection and removing of these mines manually is a dangerous task, which may sometimes causes accidents. In such situations robots aid in detection of the land mines. Not only land mines, these robots can be used to detect any other metals presented in the ground. This article explains the metal detection robot that uses RF technology. Before going to know about this metal detector robotic vehicle, get an idea about how a metal detector circuit works.
