Do you remember a game called Tank Wars? This is an attempt to make a physical version of that classic arcade game. You, the player drive an Arduino powered tank and fire a laser at a target.

This project uses an Arduino to control a tank through a web page. The tank is driven from a control panel on a web page, that is communicated to over a  WiFly. The tank uses a Parallax Ping to avoid obstacles, a servo for aiming the turret and a Tamiya tank platform for locomotion.

Why did I make this you ask? Because like everyone else I wanted to make a tank that fired lasers.

<p>I just purchased one of the Tamiya setups, and now you have shown me how to drive it around. Thanks very much.</p>
<p>cool man , can you send me a detailed document to pkompally@gmail.com</p>
<p>hey! i'm building the same tankbot with 2 motor car chassis kit. I'm studing step by step your instuctions but on the plan of tank built i can't understand why have more wires on the motors A and B. My car dosent have more than 2 wires at the same motor.</p>

<p>how u upload the without checking when i try to upload i am getting this error</p>
Does it work in different network? or has to be within local network?
Joe, <br>What does the 1750 mAh battery connect to? <br> <br>thanks, <br>high school sophomore
tankbot Web Interface help ? ?
New question. Do you not using any wireless shield with the RN-XV? How do you convert the 5V in the TX / RX to 3.3V? The specs say that support only 3.3V in the TX / RX <br> <br>Thanks.
How much did this end up costing in the end?
Which Motor shield you used? <br> <br>Thanks.
The official Arduino motorshield.
Thanks for the reply. I bought Ardumoto from Sparkfun, they use the same 298 h-bridge. <br> <br>Go job In the tank!
<p> Hi Joe, maybe if you can help with one last item. I get an compiling error message below from Servo.h<br> <br> In file included from TankBot_apr07a.cpp:27: C:\Users\Ron\Downloads\arduino-1.0-windows\arduino-1.0\libraries\Servo/Servo.h:99: error: expected ',' or ';' before 'typedef' C:\Users\Ron\Downloads\arduino-1.0-windows\arduino-1.0\libraries\Servo/Servo.h:102: error: expected constructor, destructor, or type conversion before ';' token C:\Users\Ron\Downloads\arduino-1.0-windows\arduino-1.0\libraries\Servo/Servo.h:105: error: 'ServoPin_t' does not name a type<br> <br> Servo.h code looks like this:<br> <br> typedef struct&nbsp; {<br> uint8_t nbr&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; :6 ;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // a pin number from 0 to 63<br> uint8_t isActive&nbsp;&nbsp; :1 ;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // true if this channel is enabled, pin not pulsed if false<br> } ServoPin_t&nbsp;&nbsp; ;&nbsp;</p> <p> typedef struct {<br> &nbsp; ServoPin_t Pin;<br> &nbsp; unsigned int ticks;<br> } servo_t;<br> <br> <br> This is the standard servo.h file and have not seen this before. Any thoughts? Thanks, Ron</p>
Hey Rgramza - Are you using Arduino IDE v1.0? <br><br>-Joe<br>
Hi Joe, I got it all working. I am using IDE V1.0, the problem was a missing semi colon in the credentials file. The Wifly is working great. I can see it registering the data. I don't have the sonar ping, so I have disabled those sections of code and trying to come up with a distance code more than 12 inches. Sure have learned alot in the process. Thanks for your help. All the best, Ron
Hi Joe, great instructions. Question: I have loaded xampp as a server and its working well. How do I provide access and control to my Ipad. I tried localhost and but it does not work. BTW the files are in the correct place as I am able to access them on the same computer. Thanks!
Hey Rgramza - You should put in the ip and path of the server, so if the server running xampp on and installed the tankbot code in /tankbot you would use the URL <br><br>Let me know how it goes! I just uploaded a new version of the web code and arduino code. <br><br><br>-Joe<br>
Hi Joe, well I think I am closer. Meaning I am getting a 404 error, which means server is talking but the URL is not found. I am using When I use the the full URL, I get no server. BTH I can connect to my printer page and router from the IPAD using URL http:// numbers. I have turned off the firewall and user controll but no change. xampp control panel is on and running. Your new down load looks great! Any thoughts...? I am still researching... Thanks Ron
Hey Ron - We'll get this thing working! Lets do a little trouble shooting, On the Xammp box where is the index.php located (i.e. /var/www/html/tankbot/index.php)? <br><br>On the xampp box can you tail the log file:<br>i.e. tail -f /var/log/httpd/error_log <br><br>Then attempt to browse the page from your ipad/laptop <br>Then attempt to browse the page from the xampp box (where it works already right?) <br><br>Let me know what it says. <br><br>-Joe<br>
Hi Joe, I have the index.php, tankbot header and images folder in the htdocs root directory. I now can bring up the image using explorer either using or my IP address 192.168.15.xxx or localhost. All work well. Still can't get another window xp computer or Ipad to find the site. Here are the access log.____________________________________________________________127.0.0.1 - - [05/Apr/2012:22:26:56 -0400] &quot;GET /images/tankbot-controls2_54.gif HTTP/1.1&quot; 304 - &quot;; &quot;Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/4.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET4.0C; InfoPath.3; .NET CLR 1.1.4322; yie9; Creative AutoUpdate v1.41.02 <br> <br>Not sure about tail -f var/log stuff or where to go....I have disable all the security not sure if thats the problem. It seems I need to provide privelages in the admin section to the ipad or another computer, but not sure...
Hi joe, I got it. My firewall was blocking port 80. I had to open the port, but an error message came up. So I closed and reset the port on the main computer. Now the Ipad can open and access the file. Thanks for all the help. Cheers!
That's so cool! I'm building a robot too (albeit mine is aimed at cuteness rather than super awesome laser-ness), and I'm looking for caterpillar tracks like yours. How wide are they? <br><br>Thanks!
Hey Cat - Each track is about 3/4&quot; wide. The length is adjustable and it makes the tank remarkable capable at climbing over obstacles. You can check them out here: <br>http://www.sparkfun.com/products/321<br><br>-Joe
Oo that will work perfectly. Thanks! Good luck with the contests!
Wow Joe! That's pretty cool! Great job!
Thanks jgulick!
COOL!!! how would i add a camera though???
The easiest way would be to buy a WiFi web cam and stick on the top. The arduino can't really do video over the WiFly, 9600 baud is too slow. But it would be awesome to have a tanks eye view! <br>-Joe
@Joe; Hi! Love the video, the cat, and your punchline, &quot;Because like everyone else I wanted to make a tank that fired lasers.&quot; Have tweeted. Cheers! Site
Thanks Sitearm!
can you please make a diagram using fritzing
Dude... he was nice enough to share his work... you need to do a bit of work aswell...
Nicely done. I could see two of theses battling it out.
it's very fun for stealth attack!! :)
So far it has only stealthily attacked the cat. But one day it will rise up and take part in the robot revolution. <br><br>
nice one i can vote this project pretty cool..<br>
Thanks Jhunmar!
My kinda tank! I already have a leg up on the physical tank part with a side project. May just attempt your setup! I voted for ya!
Thank tank is awesome!
Great build, I've voted for you. Is that a beer on your bench?
Bricabrac- Thanks man, nah it's just an Arnold Palmer http://en.wikipedia.org/wiki/Arnold_Palmer_%28drink%29<br>
