People assume that mineworkers would hate mice, but in reality, they don’t. They say that they get nervous when there is no mouse at all. One of the rules in mining is that you shouldn't kill mice. It is because that the mice sense the gas in the first place. When there is no mouse, it means that the situation is not good. Here, from the mice, I got the idea of a robot that detects the gas in the mine. The robot is designed to detect the gas and send a signal to the workers' helmets as soon as it senses the gas leaks. The robot's body is made of metal, and the wheels are made of thick wheels that are used off-road.
