Milwaukee (CBS 58)--They act on demand without any questions asked.  And for one recent weekend, we got to see the best of the best in action at the State Robotics Championship on the campus of UWM.  Twenty different teams compete, including an all-girls group from St. Joan Antida on Milwaukee's east side known as the RoboChix.  Seven students from this catholic school have worked since September perfecting a machine called "Frank."  His responsibility is to make sure blocks are put in a designated area within two minutes.

The Homestead Robotics team, called the 8680 Kraken Pinion, also took part in the event.  At one point just recently, it was ranked number one in the world, competing against six thousand other schools. It's now listed as third.
