With the development of robot technology and industrial automation, the manufacturing mode based on robot and intelligent equipment has been started. Intelligent tracing Automatic Guided Car (AGV) is a typical application of industrial robot. Based on MK60DN512ZVLQ10 (K60), an embedded system for electromagnetic sensing and infrared obstacle avoidance is designed. Based on the 32-bit single-chip microcomputer K60 produced by NXP, an embedded tracking system for intelligent cars is designed and implemented, which is based on electromagnetic sensing and infrared obstacle avoidance. According to the electromagnetic track laid in advance, the arrangement structure of the inductance coil and the core tracking algorithm and program are designed according to the track elements, and the automatic tracking and obstacle avoidance functions of the car are realized under the condition of no human operation. This design adopts low-cost inductance coil, which is convenient to change the track path in different environment, instead of the high-cost and hard-to-switch track path in the past, and provides a reference plan for intelligent control such as unmanned driving.
