Design and implementation of a hand gesture-controlled wheelchair

Abstract

The head movement-controlled electric wheelchair is a significant advancement in helping enhance the mobility of disabled persons. This ingenious system involves a cap-mounted accelerometer hooked up to an Arduino Nano microcontroller, which detects movements and maps them to directional instructions. This enables the exact functioning of motors with the help of a dual motor driver which is powered by a 24V battery. To guarantee the safety of the device, a voltage regulation mechanism on the exporting side acts to protect components by holding power at a specific point. Thanks to adaptive code logic, the hands-free device is made smoother and more stable throughout the project. The joystick-free system benefits user function ability but could be a cause for concern for users with a restricted hand motion. A completely new hardwired configuration (and some coding to eliminate signal noise while moving). This outcome is a cost-effective, intuitive solution that significantly enhances independence and quality of life for the end-user. This device effectively solves the theoretical problem of helping the impaired navigate through a combination of planning and design, which is what makes it such a unique solution.
