Abstract:Using wheelchairs to access the upper floors of buildings with stairs or steps is a significant barrier for the elderly, those with disabilities, and injured individuals. These days, most buildings have lifts or escalators. That being said, numerous multistory buildings in underdeveloped nations are without elevators or escalators. Additionally, some locations are not accessible to wheelchair users. In each of these situations, the aged, the disabled, and the maimed will need to rely heavily on others to carry them or, in the worst situations, not move at all. This paper discusses the idea of a wheelchair with multiple motorised wheels, actuators, and sensors that detect the existence, height, and width of a step. The actuators are then used in conjunction with worm wheel linear gears to raise and lower the wheelchair wheel axles in a controlled manner. Electronic controls are used throughout the system. This design is capable of climbing stairs without toppling over. Because the user may walk around without exerting any physical effort thanks to the motorised wheels and climb stairs without assistance, this device can greatly increase the independence of elderly and differently-abled people by allowing them to move around freely.
