基于眼电的机器人控制系统研究

Research on Robot Control System Based on EOG

提出了一种基于眼电的机器人控制系统的设计思路,该系统将操作者的眼电信号送入采集电路,通过PC机实现对眨眼次数的检测,其结果通过RS-232串行端口送入单片机,近而遥控机器人运动。介绍了系统组成,详细分析了眼电信号检测的算法及PC机串口通信程序的设计,通过分析可以看出,系统由于引入了多线程和串行通信等技术,保证了机器人控制的稳定及实时性;基于数字信号处理的眼电信号检测算法,其识别正确率高达95%。

The paper describes a system that controls robot based on EOG.System acquires the EOG from the operator,detects the number of blink and sends it to the SCM via RS-232.It introduces the components of system,analyzes how to detect EOG and to design program codes of serial communication.From analyzing we can know that thread process and serial communication technology assures the stabilization and real time of the robot;the arithmetic which detects EOG attains 95% right ratio based on DSP.
