The only company producing commercial instrumented wheels for standard wheelchairs (SmartWheel) closed its doors in 2014. Therefore, the existing wheels are no longer supported and are now obsolete. Since no new company sells an equivalent product, we started a project to upgrade the current SmartWheel and eventually build completely new instrumented wheels, with an open-hardware, open-source approach.
In the present state of the project, we currently have a complete replacement PCB with modern components, a firmware to flash its microcontroller, and a Python module to communicate with the wheel.
This repository is in heavy development; if you are interested in this project, we recommend to communicate with our team so that we can guide you, build PCBs for you, or start collaborations: chenier.felix@uqam.ca
