基于ATmega16L的小型机器人系统硬件设计

s the controller of the robot, ATmega16L is used in this system. The system chooses the serial port communication to debug the robotic single-step movements, using the wireless half-duplex communication module nRF2401 to realize the robots wireless communication. This paper discusses the basic principles of serial communication, and the characteristics of nRF2401 wireless half-duplex communication module, in addition, it introduces and analyzes the way to design the system’s PCB. Finally, it exposures the design and implementation methods of the small robotic hardware system ,including robotic control system module, serial ports’ debug module, as well as DC motor drive module.
