Manual wheelchair turned electric! This wheelchair uses electronic components such as modules and a PCB to make this wheelchair much for user interactive (and helps make life easier when you can't walk). I built this custom wheelchair because electric wheelchairs cost too much. Also it would be a great gift to my grandpa as he has Parkinson's disease. It has most of the functions on a regular wheelchair (motors, sound, speed, SOS, etc) AND I will be using AI as a healthcare tool in this project.

Customized-AI-Electric-Wheelchair: common questions
What microcontroller does the Customized-AI-Electric-Wheelchair use?
The Customized-AI-Electric-Wheelchair is built around the ESP32-C3-MINI-1-N4:E, from the ESP32 family.
How big is the Customized-AI-Electric-Wheelchair PCB?
The Customized-AI-Electric-Wheelchair measures 216.3 × 115.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Customized-AI-Electric-Wheelchair?
119 components, from 40 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Customized-AI-Electric-Wheelchair design files?
From the prisca7c/Customized-AI-Electric-Wheelchair repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Customized-AI-Electric-Wheelchair design in my own project?
The repository has no license, so all rights stay with prisca7c. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Customized-AI-Electric-Wheelchair without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
