Wheelchairs enhance the ability to move, achieve autonomy, and promote overall welfare for individuals with disabilities, physical limitations, or advanced age. The majority of individuals who use wheelchairs opt for manual wheelchairs due to their cost-effectiveness and user-friendly nature, thereby fulfilling their primary requirements. Manual wheelchairs enhance mobility, although they also restrict the extent and accessibility that an average individual may achieve, particularly those with limited endurance. The objective of this study is to enhance the connecting device, transforming the manual wheelchair into an affordable electric one. This project implemented modifications to enhance the stability of the drive unit and the linkage of the manual wheelchair. Moreover, the project incorporated waterproofing measures for the controller and power unit, as well as the integration of GPS and fall detection technology, in order to enhance the performance and safety of the electric wheelchair. By incorporating attachments and functionalities, traditional wheelchairs can be transformed into electric wheelchairs that offer enhanced mobility and include up-to-date safety features. The results demonstrated a significant improvement in the performance of the electric multi-function wheelchair attachment mechanism. The device is characterized by enhanced use, enjoyable experience, and optimal safety, fully satisfying all initial specifications. The device functions efficiently as tracking and alert devices and demonstrates excellent performance in terms of meeting size, weight, and maximum speed specifications. It is capable of securely transporting a load over 100 kg while maintaining great stability and control. This study showcases the creation, execution, and assessment of electric wheelchair accessories designed to convert a manual wheelchair into an electric one. The investigation highlights the practicality, usability, and overall impact of the accessories on the user’s quality of life.
