Using a LEGO Mindstorms NXT kit, a pair of awesome engineers put together this fully functional replica of the Curiosity Mars rover. Not only is it built completely out of LEGOs, it's motorized, programmable, and ready to explore the far reaches of your living room.
The rover was built for the Build the Future in Space event at NASA's Kennedy Space Center. Four of the six wheels are powered, allowing it to make 360 degree turns, and the arm and mast are both fully controllable. The entire contraption is piloted wirelessly via Bluetooth with a custom made NXT joystick.
