Jason Bardis uses his remote control to position "2A," his LEGO Mindstorms robot, against the much smaller "Donkey," in a qualifying match during the annual championship of mechanical robot fighting, Friday, May 14, 1999, at the E3 Gamers Convention in Los Angeles. Dubbed "RoboGladiators," the two-day, round-robin competition boasted eight of the most well-known names in mechanical robot fighting. The robots are composed entirely of LEGO parts.
