My wife, a stroke survivor, is wheelchair bound for mobility and would likely benefit from such a system. We have a Permobil C500 that I drive from an attendant joystick in the back because she lacks the fine motor control in her non-paretic arm to safely drive on her own. Due to a combination of right side paresis and motor apraxia affecting her non paretic left side, some type of collision avoidance/shared control would likely help her to be able to drive on her own.
Interesting idea and certainly would have a place in the mobility world. Are you designing a system to be an add-on to a stock chair or a whole integrated chair system out of the box? Given the costs of all things mobility and medical/disability, I can only cringe at what such a thing would cost on the market, however.

what we want to achieve is what BM does every day - eg drive through a doorway at reasonable speed without hitting the frame and without his excellent hand-eye-chair coordination.

Thats not skill. Thats the result of a normal hand and average brain. But with CORRECT HAND/JOYSTICK POSITIONING and PROPER PROGRAMMING. Which just makes it simple and the chair goes exactly where its told. You literally forget about control. And just go wharever you think you should. When you are able bodied and running, you know exactly where you will fit, and sail through any gaps. You know how fast you can stop. You know exactly where you will place your feet. Theres no prediction, or hoping... You just do it naturally. Once you have the correct technique, and programming. Then this is exactly the same.
I am a fat 60 year old. If I can do that accurately and confidently anyone with normal hand function can.
you may use a lift to wash your van - but many dont - we use it for what its purpose was made to do - assist in transfers - in and out of chair - etc, - or reach up higher in your apt. home to get something out of the freezer or cabinets etc, - those are very useful and much needed
i am sure there are many uses for a lift other than transferring like washing your van also - or when outside in Rest. to eat or what ever the Bar - your limited it without one -
i need one for transferring - easier and safer - and what ever else i can use it for is a plus -

Much like the tesla with its extremely complex self driving sensors/software that has to be controlled. Will it spot the difference between the edge of say a carpet or the dogs paw? Will it see that someones spilled liquid like cooking oil or even water on that tiled floor? I suspect that just like tesla it would need monitoring even inside a known enviroment. If the user can do that they can likely drive it better themselves? So not sure I would trust any fully autominous system with a 190kg of chair plus occupant alone. As a slow moving bot without a human, yes. In a safe (dog free?) controlled non changing enviroment.
Its like the computers (3 of them) making the ibot stand and balance. Supposedly safe. I got it to fall forwards in around 4 mins. Had to be grabbed by the rep! All I did was drive slowly across the road and up my neibours driveway ranp. It had a badly placed cracked slab that moved as I tried to climb it. I knew this and predicted that it would fall over. The rep said it wouldnt. He was ready to catch it. And it failed. Its "brain" didnt know enough.
