Purpose
A robotic wheelchair system was designed to assist disabled people with disabilities to walk.
Design/methodology/approach
An anticipated sharing control strategy based on topological map is proposed in this paper, which is used to assist robotic wheelchairs to realize interactive navigation. Then, a robotic wheelchair navigation control system based on the brain-computer interface and topological map was designed and implemented.
Findings
In the field of robotic wheelchairs, the problems of poor use, narrow application range and low humanization are still not improved.
Originality/value
In the system, the topological map construction is not restricted by the environment structure, which helps to expand the scope of application; the shared control system can predict the users’ intention and replace the users’ decision to realize human-machine interactive navigation, which has higher security, robustness and comfort.
