That's great, unfortunately he seems to have lost perspective and is developing a product no one will want at a price no one will pay.
Don't let a robot do something a human can do better.
A good example is robot vacuum cleaners: I have had one for a few years now and it's easily the best purchase I've ever made: it doesn't vacuum as well as we do but it does it everyday which is something I'm absolutely unwilling to do. Having it in my home greatly reduced the amount of time we had to dedicate to cleaning the floor and dusting non-floor surfaces (it turns out that daily vacuuming the floor has a huge impact in the amount of dust collected everywhere else).
