We have been experimenting a little more with Arduino and decided that Mobile Tape Measures are cool, but Nerf guns are even cooler! We like Nerf guns a lot but after a while it gets a little tiring to run around. Plus, the more you run, the more of a target you become. So we figure, why not put together a mobile nerf tank that will solve the problem at hand? Below is a prototype we are building, there are still a few things to do, such as adding accelerometer and gyroscope support for controlling the car and the arm, and potentially replacing the arm with actual servos - it's just more cool if it made from scratch. While this may seem a frivolous project, we actually think it may change the world (our mission). For example, nerf fights are now available to the physically disabled. Now it's fun to scold your kids - you can chase them down with one of these things in the comfort of your couch. You are an artist with no kids? We didn't forget you. Simply dip the foam darts into different color paints and you can create Nerf art by controlling multiple Nerf tanks and pre-programming shooting patterns all from a single phone. As you can see, the possibilities are limitless (ok, there are at least ten uses).
