A robot that can care for elde

A robot that can care for elder people suffering of Dementia, like the one in the movie "Robot and Frank" (very nice movie, you should see it) would be great.

I'm now busy building six to get started. I only bought the EZ-b4 controller since I live in Europe and costs after tax, customs fees and shipping already raised the bill quite high. So I would be very pleased with a some saving on buying the cameramodule and mybe some other parts (and even be more pleased with a european distributor ;-). I printed all the parts at my local Fablab, where I volunteer and give workshops. It is printed very nice with black and silver PLA. When it is ready I will post some pictures at the forum. What would be a really good addition to your allready great functions is a simple way to let the ez robots react on low voltage and go to a wireless batteryloading station, like my vaccuumbot does, and load itself. I think this would be to hard to make but it would be easy if is implemented in the ARC software. Apart from that I think I'm going to use my six, apart for fun, as a surveillance robot in my own mini fablab at home, so it can take an eye on my 3d printers and help me with tinkering. Expect my Peachy printer this year from Canada I backed on kickstarter and I backed an AI project, JEASA, also from Canada (it would be awesome to let it work together with EZb!), So I guess my place will be taken over by the Canadians! (Well, since a lot of Dutch went to Canada, I suspect they will sent things back in the end, won't they?)
