Ok, My idea...
I have reason to need a bluetooth or r/f remote controlable powered wheelchair. To be able to remotely turn it on (& off) and manouvre it from an outdoor shelter over to a freshly parked car's drivers door.
What I have at the moment is just the base power chair:
Powertec F50 by Sunrise Medical
What I wish to do as much as is possible is to leave the current set-up as it is, and to add the propsed r/c system to work along side it.
