A crawling device includes a first end with a first magnet recessed therein, a second end with a second magnet recessed therein, an elastic member disposed between the first end and the second end, a power source module, and a controller. When the first and second ends are supported on a supporting surface, and the controller connects the power source module to the first end and the elastic member, the first magnet extends beyond the first end onto the supporting surface and the elastic member becomes compressed toward the first end. When the elastic member is compressed, and the controller connects the power source module to the second end, the second magnet extends beyond the second end onto the supporting surface and the elastic member returns to the normal state. |
