| Abstract: | Intelligent transportation electric trolley system uses STC89C52RC microcontroller to control the realization of car self-tracing and mechanical hand on the workpiece to perform grasp,put and take ac- tion. Real-time timing function and display driving distance can be demonstrated. If the car meets the obsta- cle in the driving process,it can realize the automatic obstacle avoidance,which can complete the required movement and reach the end. It is proved by practice that the car system has the advantages of simple structure and high performance price ratio. It is easy to extend and transplant,and has broad application prospects. |
