Mike Brandl is a fellow LEGO MCP and all-round outstanding LEGO builder. His latest project certainly pushes the envelope when it comes to putting the NXT in a harsh environment. This time he has built a LEGO submarine that can navigate successfully underwater. The NXT is housed in a plastic sealed bag, with glue around the holes for the cables to emerge.

The submarine is powered by power functions motors; two motors can drive forward and the turntables allow the motors to rotate to permit dive/surface. Mike has trimmed the submarines to neutral buoyancy by adding and removing bricks from the underside of the submarine – I wonder how many times he sunk his sub in the process?

Good job Mike!
