Is equipped with electromagnetic or optical homing devices to along the provisions of the guidance route, with safety protection and loading function of transport vehicle, AGV belongs to the category of the wheeled mobile robot (WMR - wheeled mobile robot. Automatic tracing is used to make the car indentify route automatically, and choosing the right route, based on the automatic guide robot system. Intelligent tracing electric trolley is an advanced technology to realize automatic tracing navigation. It is out of human management but under the designed mode that use of the use of a transducer, single chip, motor drive and automatic control. This technology has been applied in unmanned vehicle, unmanned factory, warehouse, service robot and many other fields. This paper discusses the intelligent tracing electric trolley control process. During the design of Intelligent tracing electric trolley, AT89S51 single clip is used as the control core; at the same time electromagnetic sensors as the car tracing module to identify the ground laid of alternating current on guide line, which used as the car tracing module, it can gather the signal and transfer it into digital signal that can be recognized by single chip. And the driver chip L298N constitute the double H bridge
