Noah Shackman noticed a Canadian Press report saying that the Navy can't seem to find their Battlespace Preparation Autonomous Underwater Vehicle (PDF format). The bright yellow BPAUV weighs 800 pounds, is 122 inches long, 21 inches in diameter and was last seen off the coast of Norway where it was taking part in a military exercise. The BPAUV was built by Bluefin Robotics where you can find more photos and video of the robot sub. The Navy's highly automated and futuristic-looking HSV-2 Swift vessel is still out looking for the little lost robot.
