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.
