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.
I have to admit it, but iRobot’s Roomba is just the coolest thing to watch. I love how it circles around the same location over and over, how it plays a tune “Charge!” as it heads for its charging unit, and how clean it gets the areas it tackles. Fun for me — and my geek husband — who figured out where to place the sensors so it wouldn’t crash into my grand piano. And particularly appealing to have it run around under our bed, where we never push a vacuum cleaner. And from reading the reviews, it is endlessly interesting to cats and dogs.
