I'm not particularly interested in this because I'm a healthy individual, however there's a few things that interested people probably would like to know (with extra info in the video description :D): Where would this be used? At the hospital or at peoples homes or both? Were you the one controlling it or did it use SLAM + path finding algorithms to go from A to B? If you could make your product from scratch again, what would you change about it? If this is meant to be used at home, then for water I could just hook up a hose to a water supply. If you're in a country where it's safe to drink from the tap I can just hook it straight to the tap and add another valve at the end of the hose and place it next to the bed. This product sounds like it's trying to replace a wheel chair, instead of a person moving in a wheel chair to an item, the robot moves the item to the person. Don't get me wrong, I love seeing things that help people that are less fortunate. But someone has to ask the difficult questions and I think it's better if they come early from a nobody rather than an important investor.

@@harrysvensson2610 Thanks a lot for your questions, it's very helpful to be critical about who this is useful for, if anyone at all. It's also better to figure that out before you start trying to sell the idea. I think it's perhaps better here to maintain focus on Parkinson's patients, who can stiffen up basically anywhere. I think for other diseases or injuries your simpler solutions are much more effective. For Parkinson's though having a better pill dispenser, and having the water in a camel bag or something like that would be much better.
