Moving devices and controlling methods therefor

A moving device comprising:

• a first receiving device for receiving an emitted light from a base station, wherein the first receiving device obtains a direction from a start position, which the moving device is in, to the base station according to the emitted light to serve as a target direction;
• a driving device for driving the moving device to move in the target direction from the start position;
• a second receiving device for receiving the emitted light, wherein when the moving device meets a first obstacle which is disposed along the target direction and in the target area, the second receiving device obtains a distance between the moving device and the base station according to the emitted light to serve as a middle distance;
• and
• a determination device for determining whether the middle distance is equal to a predetermined distance;
• wherein when the determination device determines that the middle distance is not equal to the predetermined distance, the driving device drives the moving device to detour around the first obstacle and move in the target direction continuously and;
• wherein when the determination device determines that the middle distance is equal to the predetermined distance, the driving device determines that the first obstacle is the base station and drives the moving device to dock at the first obstacle.
