In order to make free hardware power chairs provide clear references
to functions of it. While your description gives insights, it does not
explain functions.

That is one step forward in understanding what you would need.
Here is list of free hardware Robotics devices which I have not verified,
could be non-free as well:

Feel free to provide link to instructions of that wheel chair which
will tell about its functionality.
