Abstract:
EEG-based brain-controlled mobile robots can serve as
powerful aids for severely disabled people in their daily life, especially to
help t move voluntarily. In this paper, we provide a comprehensive review of
the complete systems, key techniques, and evaluation issues of brain-controlled
mobile robots along with some insights into related future research and
development issues. We first review and classify various complete systems of
brain-controlled mobile robots into two categories from the perspective of
their operational modes. We then describe key techniques that are used in these
brain-controlled mobile robots including the brain-computer interface
techniques and shared control techniques. This description is followed by an
analysis of the evaluation issues of brain-controlled mobile robots including
participants, tasks and environments, and evaluation metrics. We conclude this
paper with a discussion of the current challenges and future research
directions.
