Millimetre defeater (Battle Bot prototype)

My school is having a battle bot competition and I signed up. If you're seeing it early on you'll see its non-functional at the moment but I will be coming back and updating the model till I have the finalised design and hopefully share off some of the fights. Assuming it survives more than one fight. Its apart of the ant weight class and hopefully works out well any recommendations would be appreciated as this is my first time making anything like this.
