Picture of TankWars: A Physical Video Game
This instructable will show the game TankWars, a web based game played on an iPad that drives a real robot tank to fire lasers at a robot. When you hit the robot target, the game is updated.

The tank and the target are Arduino's equipped with RN-XV WiFly modules, the iPad is using a PHP page to send commands to the tank and read the status of the target.

Robots, tanks and lasers, what more do you need?

This is an improved version of my last instructable, which was a much more basic version. Check that out here: http://www.instructables.com/id/Tankbot-Internet-Controlled-Tank-Robot/

Step 2: Tank Build

Picture of Tank Build
One of the failings of version 1 of the tankbot was that it was missing an object sensor in the rear. This version has Parallax Ping sensors front and rear.

You will need to assemble the following:
-Gear Box
-Tank Treads
-Universal Platform.

I used nuts and bolts to create a platform above this for the Arduino, Servo and PING.

I copied the dimensions of the Universal Plate set for the plexi glass second platform.

The laser pointer can be attached to the servo horn.

But what was really tricky for me, the Arduino Motor Shield uses up a ton of pins, but you cannot see it quickly as it is wired internally. I found it helpful to just quick sketch it out.

Very Nice Build. What would be the range of the tank WI-Fi and could you fit a camera to the tank. i can see multiple tanks running around killing each othrer as a multi player game if they had the range.

Fantastic tutorial and Instructable. This sets a foundation for so many experiments and possibilities to develop from here. Great work.
This quite awesome! :) I think it is very creative and thanks for all your hard work!
Wow. Looks pretty well. I only have a suggestion: To make an app to control the tank like you would do it with a remote control. I mean, if you release a button, the tank should stop.
Another improvement could be to control the tank with commands, like:
- up 2 seconds
- turn left 0.5 seconds
- fire
- etc (commands aren't text based but with menus)
The game then would be, starting always from the same position, try to kill the bot. If the tank doesn't kill it, or collide with a wall, then It return to the beginning. This kind of game looks a bit more hard, but more funny too (or I think so) :)

Congratulations for this good job, and excuse my poor English.

Hey DIY Justice - No it does not.
