Design of Digital Servos Control System Based on ATmega128

Conference paper
Part of the Advances in Intelligent and Soft Computing book series (AINSC, volume 158)

Abstract

Digital Servos with good performance and high accurate control via digital signal is the future development direction of robot. The form, the function and the principle of the digital servos are expatiated in the paper. System design section is composed of hardware design and software design. Each part of the hardware design complies with the modular design principles, every block is given in detail. And the software design mainly introduces data packet format of AX-12 and how to achieve half-duplex asynchronous serial communication between controller and AX-12. The application shows this digital servos controller can control AX-12, and it has been applied to obstacle avoidance for wheeled mobile robot.
