Abstract: Wheelchairs are being used for movingpatients in hospital as well as handicapped people for the last six centuries. Wheelchairs are propagated by human strength. The handicapped peoplemove wheelchairs by the use of their upper limbs or in other cases another human is needed to push their wheelchair forward. Here we propose a pretentious detachable extension which can be connected to a wheelchair and can convertnormal wheelchairs into powered oneswhich do not need humans to apply force to propagate. At the same time,this system uses batteries to move the wheelchair and in turn no fuel is needed which makes it a green vehicle. This powered wheelchair extension is designed to power normal wheelchairs and so, it achieveseffective and easier propagation method forthe patients andhandicapped people as well. This extension uses metallichollow pipes and rods together as asystem which is designed to attach to a wheelchair’s front pipe and thus clamp on it. We also use pipes and bearings connected handle designed in order to achieve motion in multiple directions. Our team is currently pursuing a chain-drive systemwhichtransmits the power of the motor to the driving wheelfor providing the motion of our extension. The extensionutilizesmultiple rechargeable batteriesin order to transmit power to the motor and a switch is placed in order to turn the power on or off and also, to change the movement to forward or reverse. Therefore, using this extension, wheelchairs will be utilized by the patients and disabled directly in order to move over shorter routes without being dependent on other human beings. Some researchare also being conducted in order to enhance the current design for making the extensionmore comfortable and more safety features can also be added in the future.
