Brain-Controlled NXT Robot: Tele-operating a Robot through Brain Electrical Activity

This paper focuses on the research of human robot interaction through tele-operation with the help of brain-computer interfaces (BCIs). To accomplish that, a working system has been created based on off-the-shelf components. The experimental prototype uses the basic movement operations and obstacle detection of a Lego Mindstroms NXT Robot. There are two versions of this prototype, taking readings from the users' brain electrical activity in real-time performance. The first version is made by using a Neurosky Mindset, and is based on the attention levels of the user as the robot accelerates or decelerates. The second version is using an Emotiv Epoc headset taking readings from 14 sensors, being able to control fully the robot.
