Abstract
This research describes the design and development of an attachable electric wheelchair that improves the performance of a traditional wheelchair by incorporating electric propulsion and advanced control mechanisms. The device operates in three independent modes: joystick, application, and voice controlled. We developed the prototype design on SolidWorks and prepared the attachable structure using metal sheets, assembling the parts through gas and electrode welding techniques. The main components include an Arduino Uno microcontroller, an ESP32 wireless module, a BLDC hub motor, and a linear actuator intended for steering. Testing experiments showed that the prototype can support users with different weights, functioning smoothly and reliably. The modular electric wheelchair achieves significantly lower production costs than conventional electric wheelchairs currently available in the market while integrating capabilities absent from the currently available products.
