World's first Lego autopilot

zlite writes: What's the best way to create a UAV for less than $1,000? Use the new Hitechnic gyro sensor for Mindstorms NXT to create a Lego autopilot! This one can turn a R/C plane into a drone, keeping the aircraft level and returning it to the launch area. Add a Bluetooth GPS module and a microcam and you've got a fully autonomous surveillance platform.
