Fortunately, researchers at the University of Tokyo are exploring just that. In a demonstration this week, a humanoid with camera eyes made by Kawada Industries Inc. poured tea from a bottle into a cup.

Then another robot on wheels delivered the cup of tea in an experimental room that has sensors embedded in the floor and sofa as well as cameras on the ceiling, to simulate life with robot technology.

"A human being may be faster, but you'd have to say 'Thank you,"' said University of Tokyo professor Tomomasa Sato. "That's the best part about a robot. You don't have to feel bad about asking it to do things."

Sato believes Japan, a rapidly aging society where more than a fifth of the population is 65 or older, will lead the world in designing robots to care for the elderly, sick and bedridden.
