Abstract
The health service sector has been continuously trying to improve the service given to the people in need of mobility assistance. As a result, more developers have been directed towards robotic wheelchairs. A robotic wheelchair is an intelligent wheelchair that has capabilities of navigating, detecting obstacles and moving automatically by utilizing sensors and artificial intelligence. We have developed a Robotic WheelChair for the quadriplegic patients for mobility assistance operated using the head gesture. The Robotic WheelChair includes accelerometer sensor, gyroscope sensor, ultrasonic sensor, relay, battery, DC stepper motor and raspberry pi. The MPU 6050 sensor detects the movement of the head and the signal is transmitted to the Pi. The controller processes the signal and enables the motion of wheelchair for its navigation. The ultrasonic sensors help to avoid obstacles, using the environment information gathered during navigation. The wheelchair is designed in a cost-effective way but ensures safety, flexibility, and mobility for the users.
