The authors investigated a single trial EEGs of the subject precisely after the latency at 400ms, and determined effective sampling latencies for the discriminant analysis to four types of arrow: ↑, ↓, ← and →. We sampled EEG data at latency from 400ms to 900ms at 25ms interval by the three channels in the right upper frontal gyrus. So the number of the variates is twenty one by three channels, therefore the sum is sixty three variates. Results of the discriminant analysis for four type objective variates, discriminant rates were mostly more than 80 %. By four type code of infrared rays according to the discrimination results from a PC, the authors have controlled a micro robot the e-puck in four orders; forward, right turn, left turn and stop.
