Mobile robot navigation through a brain computer interface

A brain computer interface (BCI) has been developed to navigate a robot by way of the operator´s brain activities. The navigation commands were displayed on a computer screen to interact with the operator. While the operator was giving the navigation command by “thinking”, his/her EEG signals were acquired by a data acquisition system through the EEG leads. The EEG signals were analyzed to identify the P300 response of the operator, and thus determine the operator´s navigation command. This command was then transmitted through a local area network to guide the robot. Feasibility of this robot navigation scheme was successfully tested with a virtual robot on a computer. The entire concept will be implemented and tested in hardware in the near future.
