Automatic guided vehicle (AGV) and automatic navigation method thereof

The invention relates to an automatic guided vehicle (AGV) and an automatic navigation method thereof. The vehicle comprises a processor, a memory, acceleration sensors, a laser positioning device and a motor for driving travelling. The vehicle enters a learning state and runs from a starting point, the accelerations of the vehicle in two horizontal directions during running are measured by arranging two horizontal direction acceleration sensors on the vehicle, the accelerations are converted into a speed by integral operation, then the running path of the vehicle is obtained and stored, and when the vehicle arrives at the end point, the vehicle ends learning; and after the vehicle enters a running state, the vehicle runs according to the stored path. The vehicle can automatically record the running path and has higher flexibility and applicability.
