摘　　要：随着机器人技术的飞速发展,声控轮式机器人得到了越来越多的关注。以LM3S811芯片为核心,设计了一款声控轮式机器人。语音模块采用LD3320,经特定的麦克风处理后,通过AD转换,将数字信号发送给控制芯片处理,处理后的信号会根据不同的,语音命令转换为对应的数字信号传输到LM3S811中,从而改变PWM的占空比,不同的占空比会控制电机的不同运动,从而实现对轮式机器人的不同操作。With the rapid development of robot technology, more and more attention has been paid to the voice control wheeled robot. In this paper, a voice control wheeled robot is designed with LM3S811 chip as the core. The voice module uses LD3320, the microphone handle specific, through the AD conversion, the digital signal will be sent to the control chip processing, the processed signals according to different voice commands, converted to digital signal transmission corresponding to the LM3S811, thereby changing the duty ratio of PWM, different duty ratio corresponding to different operation action the wheeled robot, so as to achieve the operation of wheeled robot. This achievement has been completed and will be applied in the provincial planning.
