Design of Wheelchair Using Body Position Tracking Designed For Paralyzed Patients

A wheelchair is a mobility aid for a person with physical deficiencies or problems that cause him to be unable to use his legs to walk. For people with paralysis, such as those with nerve pain or paralyzed people on their hands and feet, to be able to move the wheelchair, they need someone to help push or move the wheelchair. Otherwise, the patient must use his power to move the wheelchair by hand. In certain conditions, the patient cannot move his hands and feet or does not have hands and feet to perform positional shifts. In this study, we designed a body position-controlled wheelchair for paralyzed patients to make it easier for them. The development relates to an electric wheelchair controlled by body position. The aim of creating this tool is to help people with physical disabilities, especially those who experience problems with their legs and arms, to be able to move from one place to another and to support them to carry out activities independently without the help of other people. This electric wheelchair has an automatic control system based on the user's body position. When the wheelchair is occupied, the load sensor receives the load and provides analog values to be processed in the microcontroller and converted into digital data to move the two motors connected to the wheels. In this way, the user can control the wheelchair by moving the body forward, back, right, and left and setting the speed according to the user's body inclination.
