Design of Mobile Robot Based on PWM Control Technology
This paper introduces a mobile robot control system which is constituted by a high speed single-chip C8051F021.It describes the PWM control principle,the hardware design,test result and analysis.The system uses ambipolar H-bridge as the drive circuit and adjusts the direction and speed of people by changing voltage polarity and value of PWM.The practice indicates that the design of the circuit is reasonable and is fewer requests for the ground with advantages of strong adaptability,low cost and strong practicability.
