University of Washington researchers can control the movement of a humanoid robot with signals from a human brain.
Rajesh Rao, associate professor of computer science and engineering, and his students have demonstrated that an individual can "order" a robot to move to specific locations and pick up specific objects merely by generating the proper brain waves that reflect the individual's instructions. The results were presented last week at the Current Trends in Brain-Computer Interfacing meeting in Whistler, B.C. . . . The controlling individual — in this case a graduate student in Rao's lab — wears a cap dotted with 32 electrodes. The electrodes pick up brain signals from the scalp based on a technique called electroencephalography.
