One more question. Let's assume we sell the power assist as is and the user has "normal" sized casters. If you are holding a joystick (like the one below) with one hand, is it possible to still wheelie over an obstacle?
Have you changed your idea from your original of an add-on to a whole system or a complete chair? What you had that I saw was a good idea. Now it seems you are trying to be all things to all people.
