Education-oriented portable brain-controlled robot system

Abstract

In this paper, we develop an education-oriented portable brain-controlled robot system, consisting of a multi-parameter bioelectric signal acquisition device and a Lego NXT Mindstorms robot. The education-oriented portable brain-controlled robot system is only 45 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> in volume and weighs 70g. The signal acquisition section wirelessly acquires brain signals and the control section remotely navigates a Lego robot via brainwaves through a Bluetooth. Teenagers may use the low-cost brain-controlled robot to enjoy the pleasure of learning, to inspire their innovative ability and creativity, and to raise their mental concentration. Moreover, the proposed brain-controlled robot system might be used to improve the quality of adolescent education and autism recovery. The system modules include the brain signal acquisition, signal processing, and the robot control, which are developed in LabVIEW-based programming environment and easy to be expanded and upgraded. The comparative study of the education-oriented system and Cerebot equipped with the high precision Cerebus system widely used in laboratory research shows that the low-cost system delivers comparable accuracy for the robot control. An operation task is presented to train users' attentions and concentrations.
