摘　　要：设计了一种新型的网球拾球机,介绍了拾球机的机械结构设计、控制硬件电路和控制程序设计。该新型网球拾球机的两个后轮分别由一个直流电动机驱动,两个后轮带动前轮转动,前轮与一个拾球滚筒通过单向推力轴承联接,实现拾球机在行走的同时进行自动拾球,并将网球暂时储集在一个容器内,当网球装满时又会及时提示。直流电动机则是由单片机根据无线电遥控指令来进行驱动,另外在拾球机上安装了红外反射式传感器,可实现自动避障功能。该新型的网球拾球机具有结构简单、自动化程度高和速度快等特点,并且大大降低了拾球的劳动强度。This article presents a new type of tennis ball picker,the design principle of mechanical structure,control hardware and control program are introduced.The two rear wheels of the new tennis ball picker driven by a DC motor separately and two rear-wheel drive front wheel rotation,picked up the ball with a front roller thrust bearing through one-way link,the tennis ball picker achieves walking at the same time automatically picks up the ball,and balls will be stored in a container temporarily.When the container is full the picker will promptly prompted.The DC motors are driven by the microcontroller based on radio-control command.In the other hand,the ball picker installed an infrared reflective sensor enables automatic obstacle avoidance capabilities.The new tennis ball picker has a simple structure,high automation and high speed,and greatly reduces the labor intensity of picking up the ball.
