【 摘 要 】

The purpose of this study was to design of electric wheelchair. A wheelchair is a tool for people with disability. In general, a wheelchair is still controlled by hand or using a Joystick electrically, so users with a disorder can perform activities without any help. The research was designed to help disabilities who do not have hands and feet. So there needs to be wheelchair control without the use of hand or foot muscles. Therefore, it is designed an electric wheelchair that can be controlled based on brain wave activity using EEG sensors. EEG sensor is a device that can detect the activity of human brainwaves, this sensor can be used for control on a movement direction of a wheelchair, based on the parameters Blink detection and Attention. The laptop device is used as a LabVIEW-based programMing control center that is associated with the Arduino as a communication between input and output components. As well as the ultrasonic distance sensor HCSR-04 is used as a wheelchair safety. Wheelchair movement can be controlled automatically, with the movement forward, backward, turn right and turn left, with an average success rate of 80%. This is because there is instability in detecting brain signals. Wheelchair ability in bringing user load is less than 130 kg.
