An engineering student has built an underwater vehicle using a Lego Mindstorms NXT and a pair of NXTBee chips.

NXT, which is a programmable robotics kit, allows the inventive to make little Lego robots, while the chips allow for wireless communications.

The student, known as Brane, used the components to make a steerable submarine for his final-year engineering project.

The robot is not actually waterproof, simply sealed with epoxy and powered by two lead-acid batteries attached to the robot's base. It is then controlled by an Xbox 360 controller, hooked up to a laptop.

Since it can only be underwater for short stretches of time — Brane said 20 minutes on his YouTube page — we can't imagine what the practical applications might be, but we kind of want one anyway.

Check it out in action in the video below.

This underwater vehicle actually uses the Dexter Industries NXTBee for communication, not an Xbox controller. We did a post about it on our blog here:

More info on the NXTBee for LEGO MINDSTORMS is here:

Hi John,

Isn't that what I said? I also included a link to your post :)
