Yahoo has some pictures of bipedal combat robots from the Robo-One Grand Prix. The robot combat competition was held in a makeshift ring at the 2003 Internation Robot Exhibition in Tokyo on November 22nd. The robots were displayed with the hopes of promoting robot technology and their user-friendliness. This is the same Exhibition that brought other great robotic displays such as Actroids and Epson's uFR Micro Flying Robot.
