A car-like mobile robot design and implementation

This paper is devoted to design two different systems for a car-like mobile robot (CLMR) with system simulation. We analyze the requirements of the CLMR system and then propose a system structure of the CLMR. On this basis, the system simulations for different reference trajectories are provided in this paper. Simulation results illustrate the dynamic performance and the effectiveness of the scheme. The CLMR system developed in this paper is composed of a micro controller unit (MCU), a servo unit, photoelectric sensors, an encoder, and four DC motors. The real-time experiments of the CLMR system are also provided. Then we compare the performance of two systems. The whole system is proved to have an excellent dynamic characteristic and stable capability. Finally, some further researches are provided on the CLMR.
