RoboCup has a web page. The RoboSoccer project at CMU has a web-page... and Sony has a more human interest web page too (This page includes more movies of the pets and interviews with many people including me).
The Pittsburgh Post-Gazette has an article about our team (it's a local newspaper human interest story - not the best place for technical info :). They did a followup story when we won at RoboCup98.
Speaking of RoboCup, Here's the RoboCup 1998 SONY legged robot photo album.
