MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611107714 A) filed by Maharishi Markandeshwar Deemed To Be University on September 05, 2026, for Arduino-Based Voice Control Wheelchair.
Inventor includes Tejinder Kaur.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: An Arduino-based voice-controlled wheelchair system is disclosed to provide independent mobility for physically disabled individuals, particularly quadriplegic patients. The system comprises an ATmega328-based Arduino Uno microcontroller board, a speaker-dependent V3 voice recognition module with a microphone, an HC-05 Bluetooth module for wireless signal transmission, and an L293D motor driver IC driving left and right DC brushed motors. Safety and obstacle avoidance are provided by a front-mounted HC-SR04 ultrasonic sensor along with side-mounted infrared (IR) sensors with a 10" cm" to 80" cm" detection range. To ensure smooth and steady movement, the system includes a speed-monitoring feedback loop featuring twelve magnets spaced around 40.64" cm" diameter wheels and Hall effect sensors that feed rotation data to the microcontroller for pulse-width modulation (PWM) speed adjustment. The cost-effective system enables hands-free operation via personalized voice commands or smartphone inputs.
