Overall, we believe this project  was fairly successful. There were a few bumps in the road, but ultimately our car did what we wanted it to do. The turret was able to swivel around and move up and down as intended. We did not end up attaching a firing gun but managed to wire the lights up through the cardboard gun to the tip and through the arduino causing the lights to have alternating flashing when the button was pressed. The button on the controller that affected the car remotely stopped working after a few re-wirings so the final product did not have that function, rather there was a button on the car that caused flashing lights. Initially, the button was working when we attached a motor to the circuit, but when we attempted to connect the lights, the button would not turn them on. The car could be driven around with a remote that was different than the one used to control the turret. We were able to drive it around the expo and aim it at people, which was fun until we inevitably crashed it. We modeled most of the components in solid works and 3D printed and laser cut some parts, but ended up making some components by hand.

There were a few things we would change if we were to move forward in the design process. The major problem we encountered when running our model was that the wheel that rotated the turret kept slipping out of the rut we made. Thus, instead of having a wheel rotating in a rut here are a few other solutions, we could either add more cardboard rings to increase the surface contact the wheel had with the rut, we could add a lip on the rut so the wheel would not slip out, or (and we believe this is the best option) we could have replaced the wheel with a gear and turn the rut into a gear as well. This way all of the parts would rotate without slipping out.

As noted earlier, on the whole, this project was a success. Although there were some issues along the way, this is ultimately a prototype, and we are aware of the problems that need to be fixed. If we were to (and we may) keep working on it these problems would/will be addressed.
