I need to navigate a robot on the football field and I was thinking about using pieces of metal either under the grass or perhaps on it. I want to buy k7102 kit, however, I am not sure if the sensor will be able to detect such metal. I could use basically whatever size and material of the metal. Alternatively, I could mount a piece of magnet on it. The speed of the robot will be 0.05m/s and when on metal the speed could be reduced. So will be k7102 able to detect metal (with magnet) or not?
Thank you very much for any advice!
In theory, this could work. However, the robot circuits and parts will probably influence the metal detector circuit. As this is a low cost kit, it is worth a try. Good luck
