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.

There is a drastic lack of networking infrastructure in unstable or remote areas, where businesses don’t think they can reliably recoup the large initial cost of construction. Our goal is to bring the internet to these areas. We will use a network of extremely affordable (<$20, made possible by IoT technology) solar-powered nodes that communicate via Wi-Fi with one another and personal devices, donated through organizations such as OLPC, creating an intranet. Each node covers an area approximately 600-800ft in every direction with 4MB/s access and 16GB of cached data, saving valuable bandwidth. Internal communication applications will be provided, minimizing expensive and slow global internet connections. Several solutions exist, but all have failed due to costs of over $200/node or the lack of networking capability.

To connect to the internet at large, a more powerful “server” may be added. This server hooks into the network like other nodes, but contains a cellular connection to connect to the global internet. Any device on the network will be able to access the web via the server’s connection, effectively spreading the cost of a single cellular data plan (which is too expensive for individuals in rural areas). The server also contains a continually-updated several-terabyte cache of educational data and programs, such as Wikipedia and Project Gutenberg. This data gives students and educators high-speed access to resources. Working in harmony, these two components foster economic growth and education, while significantly reducing the costs of adding future infrastructure.
