My chair has been severely hacked on, and bears no close relationship to the original product - I've replaced the entire electrical system other than the motors, and made many other modifications to it.
The current control system on it is a Penny & Giles (P&G) "Pilot +" which is technically obsolete and no longer manufactured, so parts are only available used. It has the advantage of being the easiest system to get into with the proprietary, MSW only programming software, as all it needs is a special cable that has been reverse engineered and is relatively easy to make. I don't have much in the way of current photos, and don't see how they would help much since it basically would just be 'black box' electronic modules. I did post a basic description of how almost all powerchairs work, and mine is very typical of a basic chair with no special seating functions. (I do have a project chair w/ fancier seating, but it is not much different. I am a very active participant on the <WheelChairDriver.com> website, which is probably the top site in the world for people that hack on and do their own repairs of power chairs. One of the members there has created as close to an Open Source Hardware control system as we have. It is based on multiple Arduino Tinies and is a very complete system, but it STILL requires a proprietary Roboteq robotics controller, and a lot of very hairy scripting in Roboteq's proprietary BASIC language. The Roboteq controllers were chosen because they were the only ones he could find with the extra functionality for the Fail-safe / Safe-fail monitoring needed on a power chair (or any other 'life safety critical' device) It is also a factor that high power motor controllers are NOT simple, as a lot of the 'minor' things that get mostly ignored in basic electronics become major factors. Even so I'd love to attempt doing one of those setups, except for the estimated $1-2K cost...
