An automatic tracking mobile platform that works logically and practically. The process of making it is simple and cost efficient. An emitter is carried by the user; this emitter transmits various electromagnetic signals including infrared, visible light, laser, or ultraviolet. The platform has electromagnetic sensors connected to its front wheel which synchronously turn with it, and these three sensors are separated by panels. The panels block one sensor from the others so that only one sensor can respond to the transmitter at any one time to turn the platform left or right. An electrical motor and a mechanical steering wheel are connected to the front wheel, which drives the mobile platform. The receiver is set to screen electromagnetic signals from the transmitter so the platform can turn to the left, turn to the right, start, or stop to accomplish its automatic tracking purpose. To reduce interference from the reflection of direct sunlight on the platform sensors, horizontal grade gratings are placed in front of the sensors. The receiver sensors can receive signals directly from transmitter. Other inventions do not include provisions to increase the sensitivity of the sensors in the presence of reflections of direct sunlight. Moreover, in order to avoid reflection interference, especially indoors, laser light can be used to help the platform track the user successfully.
