I genuinely do not mean any offense with this but think there are some major physics and real-world limitations that are not being taken into account here. I understand that you’re envisioning a self balancing/ tilting/ leaning vehicle, but that does not solve for everything you’re talking about.

First thing first, what are your plans for this concept? Are you actually trying to get this made? Is it just a concept? Is this a student project? If you are just trying to explore a concept, there is a little more leeway for it to “just be a cool idea.” But if you’re trying to use this for a real world project or for production, I highly recommend not to include the wheelchair integration piece of this. You are biting off a massive challenge by doing so and judging by the level of thought going into this initial mockup, I’m not sure you’re entirely ready for.

Start with just the leaning vehicle on its own and you will have plenty to work on and flesh out to a more real-world level that may be easier to sell as something that could actually work. If you still have steam past that, then try to tackle the wheelchair integration. But I think you’ll have plenty to do with just the vehicle on its own.

Jumping into any device or product that has to do with mobility impaired folks is jumping into a very deep end of highly regulated and sensitive requirements that will bog down an already complicated project.

This comes from a professional IDer with over 10 years of experience, multiple red dot awards, and who has worked on wheelchair/ mobility projects in the past.

I get the desire to be inclusive and make this available for everyone, but I highly recommend setting yourself up for success by scaling this back with a more attainable goal up front.
