This looks like a simple and elegant solution to a very real problem that affects lots of people's lives. But I can't help but think that in addition to the obvious upside of giving people a lot of autonomy, there's a significant downside here that should not be ignored. The flip side of making basic life activities easier is that if a person gets used to it, it can be pretty easy to slip into the complacency of relying on the device and actually never regain full normal function. I wonder if it would be feasible to augment that system with a leverage/resistance control that could be gradually changed. From my cursory look at the video it looks like there's some kind of mechanical leverage system in place (or at least there could be). Then a rehab schedule could start someone on, say, a 2x force multiplier and then gradually dial that back to 1x, and perhaps eventually < 1x which would then start to function as a strengthening / resistance training regimen.
I imagine this kind of graduated assistance/resistance feature would probably increase cost, complexity, and maintenance a meaningful amount. Question is, how much? Perhaps it might be worth it?
