Sony QRIO Robot visits a Tokyo recording studio Thursday to dub a voice part for Astro Boy a popular Cartoon series, where the talking, dancing robot makes a cameo appearance.

Surrounded by a pack of photographers, the 58-centimer-tall (23-inch-tall) silver robot with glowing eyes walked slowly up to a microphone, stopped, waved and muttered, ``All this attention is making me nervous.''

Sony's humanoid robot, called Qrio, uses software that changes text into an electronic voice. It took up its new challenge with gusto, delivering a couple of lines for an episode of ``Astro Boy,'' a weekly TV show from Sony Pictures Entertainment, set to start airing in the United States Saturday.
QRIO, which stands for ``quest for curiosity,'' isn't for sale.
