400 Battle Bots Fight, Toss Enemies At RoboGames Competition 58
Andre writes "The 6th annual RoboGames were held in San Francisco last weekend. They welcomed a horde of 400 non-sentient, metallic warriors to do violent battle — against each other, of course. This army of remote-controlled and autonomous combat robots, along with walking humanoids, soccer 'bots, sumo 'bots and even androids that do kung-fu, was put to the test. Among the big winners was Canadian-made 'Ziggy' — one of the combatants in the 340-pound, super-heavyweight division (the biggest division) — who took home a gold medal for the fourth year in a row. The bionic brute proved its might against its final opponent, the 'Juggernaut,' by tossing it around like an empty pop can (and promptly making a mockery of its name) using a pneumatic flipper. Ziggy's newly-improved weapon results in unwanted (but totally cool) free-flying lessons for its opponents. At full power, the flipper can launch an opponent to the arena ceiling."

Ignore the "battle bots". Check out the humanoids. (Score:5, Interesting)
The "battle bots" are mostly the usual stupid R/C "battery-motor-wheels" stuff. But some of the humanoid hobbyist robots on display are getting good. Dynamixel servos, which have useful feedback to the controller, are taking over. (They have a 1mb/sec polled serial link shared by all the servos. It's RS-485, which is 1970s technology, but that's progress over the usual one-way PWM interface.) The latest prototype Dynamixel servos can reach 500 degrees/sec, which means there's hope of making legged running work. Some of the humanoid robots have a 6DOF inertial unit, although balancing software is way below the Big Dog level and none of the humanoids had force-sensing feet.
The better hobbyist humanoids are almost at the hardware level at which Asimo/Big Dog performance becomes possible. The more advanced robot hobbyists now understand about ZMP. We're getting there.
