I have been searching the web for robots that could be useful to seniors -- today. Yeah, I know that's a tall order. So much research, so few commercial products, and I really don't want to count the companion toy dogs. And while vacuum cleaners and floor washers are interesting and available through Target, they're not quite what I had in mind for helping seniors stay safely in their homes. And the research programs, funded by every company (including Toyota, Sony, etc., etc. and its mother, don't seem to have commercial product near ready.
