This cute little tank robot uses an Arduino and WiFly shield along with a laser. Creating a web page using PHP, Joe is able to control the tank on his iPad over the internet, including aiming and firing the laser.
Joe has also created a cool target that lights up when it gets hit. I can easily see a couple of these tanks battling it out with the targets attached on top of them Now if he would only build another tank, set up an arena, add a webcam and host a tank shootout.
Nice job Joe.
