DESIGN AND DEVELOPMENT OF A SAFETY-BASED HAND GESTURE CONTROLLED WHEELCHAIR USING ATMEGA8 AND DUAL ULTRASONIC SENSORS
This paper presents the design and development of a safety-based hand gesture-controlled wheelchair prototype using an ATmega8 microcontroller. The system uses an MPU6050 sensor to detect hand tilt gestures for movement control. A touch sensor is used for safe activation, while two ultrasonic sensors are used for front obstacle detection and staircase edged etection. The ATmega8 processes all sensor inputs and controls the motor driver circuit for safe prototype emovement. The system is powered by a 12V supply, with a voltage regulator providing 5V to the controller and sensors. The proposed system is low-cost, simple, and suitable as an assistive mobility prototype with improved operational safety
