Design of a Brain Controlled Wheelchair

The brain machine interface has a profound impact on paralysis or the life of the elderly. They can control all kinds of equipment without the need of both hands. The electric wheelchair has become very popular. This article introduces us to control the wheelchair by replacing traditional arms with EEG signals. We control the rotation of the wheelchair by the times of intentional blinking. The concentration of the signal in the EEG is taken as the signal to control the wheelchair, and the signal is transmitted to the STM32 to realize the forward control of the wheelchair. We have done a lot of tests to keep the error rate of the system at a lower level and the reliability of the system is high. In the future we will do adaptive threshold setting.
