Robots on the Web: Can Robby Come Out to Play?

Imagine a small, bright-red, oval-shaped canister vacuum cleaner, about 2
feet by 1 foot. It has no hoses or attachments; instead it has lots of
eyelike sensors and a small video camera mounted at its slightly slimmer
front end. That's the basic AmigoBot, a simple remote-controlled robot. Its
sensors allow it to avoid objects automatically while rolling around on its
one small and two larger wheels. 

It can keep a friendly eye on at-risk elderly relatives living alone. Or it
can enable brief play sessions with your pet during your lunch break, or let
you play with your kids while you are on a trip, say the manufacturers.
