Nice hunt @muhammadhateeb!
This is a truly remarkable invention with it's ability to drive though grass, snow, sand & gravel. I've never heard of a 4 wheel drive wheelchair until now which makes it great to get through almost anything which a standard chair wouldn't even have a chance.
With the ability to climb stairs and stand upright for greater access is absolutely incredible!
This Ibot is a great game changer for the lives of the disabled and this will surely help them to gain much more freedom & independence for themselves.
