Mobile Shooter better prototype

Hello to all, this is my first upload. I created this for two purposes, to demonstrate how servo motors work for beginners; and for the proposition of using more force based weapons rather than a handy mini emitter emitting land mines. There are already a few, and to those I say kudos. I know this design is archaic at best, in comparison to most of the things on the community, but it is merely a proposition, or perhaps, inspiration for something bigger and better. Thank you. Please feel free to make derivatives of this device or use anything you gained from it, if anything.
