Machine Intelligence Lab, University of Florida

You may not be a kid any more, but there’s no rule that says you can’t still play with bathtub toys. Bigger, better, robotic toys.rn

rnOver the weekend in San Diego, that’s the spirit that brought together an array of teams looking to make waves at the 9th International Autonomous Underwater Vehicle Competition. The vehicles had to demonstrate their autonomy by completing three tasks–rendezvous with a docking station, inspect and mark a pipeline, and home in on an acoustic beacon–within a 15-minute performance period. Entrants could not be more than 6 feet long, 3 feet wide and 3 feet high, and had to weigh less than 140 pounds.rn

rnThe winner of this year’s contest was the University of Florida’s SubjuGator. No one would mistake the SubjuGator for a desktop PC, but it does run a version of Windows XP.

The 2006 version of the SubjuGator is the fifth generation of the autonomous submarine, with about 70 percent new parts in rebuilding the 2005 design, including most of the electronics. And last year’s model was no slouch, either–it, too, finished in first place.rn

rnThis year’s SubjuGator uses the embedded version of the Windows XP operating system on a single-board Pentium M computer, which run the vision system and advanced signal processing. Other components include sensors, motor controllers and microcontrollers. It was designed and built by students in the University of Florida’s Machine Intelligence Lab.

Most of the entrants were from the U.S., but this one–called Sonia, for systeme d’operation nautique intelligent et autonome)–came from the Ecole de Technologie Superieure in Montreal.
