The electromagnetic induction guided AGV uses electromagnetic induction to recognize the road. The electromagnetic induction guidance of the AGV is generally on the ground. Wires are buried along a preset driving path. When a high-frequency current flows through the wires, an electromagnetic field is generated around the wires. Two electromagnetic sensors 5 are symmetrically installed on the AGV.
