Tank
This is my second and largest project. It uses all the sensors as well as the Nissan Frontier. The only thing missing in it is the Treads. It really has a gun built on top of the turret which came from the educational resource set. The Ultra Sonic sensor is built up front as you can see and the light sensor is in between two motors at the bottom. The sound sensor is intergrated into the tank and the touch sensor is in the back. It took my about 2 hours a day for about 3 days to build this tank.
