Underwater Robots for Everyone

From Slashdot:

"'A small 112-pound ocean glider named Spray is the first autonomous underwater vehicle to cross the Gulf Stream underwater. Launched September 11, 2004, it has been slowly making 12 miles per day measuring various properties of the ocean. Spray spent 15 minutes three times a day on the surface to relay its position and information about ocean conditions and then glided back down to 3,300-feet depth .' And reader RoboFreak writes 'Two Computer Science students at Brigham Young University-Hawaii have developed a Low Cost Autonomous Underwater Vehicle. "
