全息脑控阿凡达机器人系统设计

Holographic Brain-controlled Avatar Robot System

"阿凡达"是美国科幻电影中构想出来的一种能利用人的意识控制克隆生物体的脑电系统。为实现此套系统功能,提出了全息脑控阿凡达机器人系统设计方案,由可穿戴脑电设备及人形机器人组成。基于ARM Cortex m3的可穿戴脑电设备集成了μV级别高速高精度脑电采集放大电路,实现脑电信号精确解析。基于STM32的智能人形机器人集成了音视频和温湿度等多种传感器,可实现环境信息的实时采集反馈。两者通过无线通信,实现远程脑控。经实验测试,基于稳态视觉诱发和运动想象两种脑电现象的平均识别准确率分别可达93%和78%,并能正确控制机器人执行相应动作,且各传感器参数能正确反馈。分析可知,本方案合理可行,实现了预期功能,是国内第一个实现的具有完整自主知识产权的全息脑控阿凡达机器人系统。

＇Avatar＇ is an EEG system,conceived by a science fiction film in the United States,through which human can control cloning organism by one＇s consciousness.In order to realize the function of this system,a design of Holographic brain-controlled Avatar robot system is proposed,consisting of a wearable EEG equipment and a humanoid robot.An ARM Cortex m3-based wearable EEG device integrates a μV level high-speed high-precision EEG acquisition and amplification circuit to achieve accurate analysis of EEG signals.A STM32-based intelligent humanoid robot integrates many kinds of sensors like audio,video,temperature,humidity and others,which can achieve real-time environmental information feedback.Both through wireless communication to achieve remote brain-control.The experimental results show that the average recognition accuracy of the two EEG phenomena（Steady-State Visual Evoked Potentials,SSVEP and Motor Imagery,MI） is 93% and 78%,respectively,and the robot can perform the corresponding action correctly,and the sensor parameters can be fed back correctly.Analysis shows that the design is reasonable and feasible to achieve the expected functions,is the first to achieve a holographic brain-controlled Avatar robot system,with complete independent intellectual property rights.
