This tank is a very compact, treaded vehicle. It is remote controlled by the tilt controller in the step after the next step.:p The touch sensors in the front are programmed to make the tank back up if the tank is controlled into an object in front of it.
The gun of the tank doesn't actually shoot it-it just moves up and down. It is geared vertically so the motor's energy is moved towards the top. It moves up and down forever when the remote control program is running. You can kind of see the gearing in pic 2.
Here is the controller i use to move the tank. The color sensor moves left and right and the yellow bricks move forward and stay level. When the color sensor sees different or no color it does different actions like moving left, right, forward, or stopping. Unfortunately, it isn't able to move backwards.
The movie, and (maybe) ldd of the controller will be coming very very soon. The program is now here though! :D
Overall, this is by far my best project so far. I hope that this may win the color sensor award in the challenge. You can probably expect another entry to this challenge too. I hope you liked it!! Please comment and rate!!!!! oh and visit my other projects and comment on them too!
