In order to make free hardware power chairs provide clear references to functions of it.

Here is list of free hardware Robotics devices which I have not verified, could be non-free as well: https://en.wikipedia.org/wiki/List_of_open-source_hardware_projects#Robotics Feel free to provide link to instructions of that wheel chair which will tell about its functionality. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.
