An Infrared- and Gesture-Controlled Wheelchair Robot

Abstract

New developments in sensor integration and automation have led to significant improvements in mobility solutions for those with physical limitations. Many people with little dexterity in their hands may find that traditional wheelchairs, which employ joystick controls, are too difficult to use. The development of gesture-controlled wheelchairs, which enable users to direct the wheelchair's motions by body gestures, is a solution to this problem. An accessible and efficient mobility solution is the subject of this project, which involves a home automation system and a gesture-controlled wheelchair that incorporates infrared sensors, an L293D motor driver, a buzzer, and MEMS (Micro-Electro-Mechanical Systems) sensors. Wheelchair navigation instructions are translated into motion by the MEMS sensor, which recognizes hand or head motions. The L293D motor driver receives these instructions from a microprocessor and uses them to move the wheelchair in various directions, including forward, backward, left, and right. One use of the infrared sensor is home automation, which allows customers to remotely operate various electrical equipment. This improves freedom by letting people with mobility issues use common home appliances without touching them. An additional safety feature is a built-in buzzer that notifies users or caretakers of impending danger, malfunction, or other issues. The easy, hands-free manner of operation provided by the gesture-controlled wheelchair empowers users. Users may effortlessly maneuver the wheelchair using this method, as opposed to relying on conventional joysticks or button-based controls. Home automation elements that may be controlled by an infrared remote further increase convenience, allowing physically challenged folks better access to their surroundings. The low cost and simplicity of integration with preexisting mobility devices are two of the system's main features. Lightweight and without requiring complicated calibration, the MEMS sensor technology used for gesture detection is perfect for practical uses. With the infrared sensor for home automation, users may easily turn on and off lights, fans, and other appliances. As a crucial safety element, the buzzer alarm system notifies users in the event of problems or obstructions in the wheelchair's route. People with severe mobility disabilities will be able to reclaim their freedom and control of their environment thanks to this project's substantial contribution to the evolution of assistive technology. This offers a complete and functional solution with its integration of MEMS-based gesture control, automation of infrared sensors, and motorized wheelchair mobility with L293D motor drivers. More improvements, such Internet of Things (IoT) connection and voice control integration, might make the system even more accessible and allow for remote operation. The ultimate goal of the home automation system and gesture-controlled wheelchair is to provide physically disabled people with a more intelligent, efficient, and user-friendly means of transportation, hence improving their quality of life.
