Photos: Toy Fair fun, from bots to Chix

Hitec's Robonova-1 humanoid biped robot has been a big hit in Japan, where robot enthusiasts build the 'bots and use them to fight each other. The robot made its U.S. debut at the International Toy Fair in New York City this week. The Robonova-1 kit is designed for serious robotics fans and costs about $1,000.
