Motion control for intelligent wheelchair using Emotiv perception

ZHANG Yi,ZHANG Hui,LUO Yuan,HU Huo-sheng(National Engineering Research & Development Center for Information Accessibility,Research Center of Intelligent System and Robot, Chongqing University of Posts and Telecommunications,Chongqing 400065,P.R.China)  
A control system for intelligent wheelchair based on motor imagery is designed by using Emotiv sensor.In this paper,independent component analysis(ICA)is used for electroencephalogram(EEG)denoising and feature extraction,and then the extracted features are classified as imagining left and right hand movement,legs movement and neutral state by back propagation(BP)neural network.Finally,the four control commands(turn left,turn right,forward and stop)are designed to achieve real-time control of intelligent wheelchair.Experiment result shows that the control system has better feasibility and stability.It establishes a basis of practical application for EEG control intelligent wheelchair.
