|13||IR Tracking NERF Sentry Gun
||Christian Ryan Alvaro
|This project aims to create a deployable NERF sentry gun. This project is unique in the sense of adding an ECE spin to a common toy blaster. While the idea of sentry guns has been done before, what sets this project apart from the others is two-fold. First, its tracking system relies on infrared, versus most other systems that rely on webcams and OpenCV. This leads into the second point, portability. Because of its lighter hardware requirement in tracking, specifically in not needing an entire computer, the system should be redeployable at will.
In terms of hardware, we plan on using a ATMega microcontroller as the brain of the project. For sensing, it'll use an IR receiver from a Wiimote and interface with the microcontroller whenever strong IR beacons are sensed. The microcontroller would command servo motors in a pan-tilt configuration to aim, all before spinning up the flywheel motors and dart pushing motor via transistors connected to the pins of the microcontroller. We'll need to design a control system in order to balance it's responsiveness with it's precision, since fast acquisition may result in overshoot and a missed target from its own momentum, while slower movements may result in missing a shot at the target.
