Functions of General Design

Specifically designed to meet requirements set by the ASMEShould be able to cut out the 9 circle-shaped extrusions found on the base and press platesShould then fold the cut out piece of paper in half by using a knife to push the paper between two rollers which are side by sideUsing an offset shaft, our design allows for cutting/folding to happen practically simultaneously Once folded in half, the next function of the design (2nd subsystem) is to form the final shape of the projectileShould be able to launch the final projectile a considerable distance
