Channing Philbrick proposal
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.

Featured Project

Our project explored the every-expanding field of drones. We wanted to solve a problem with the dangers of plastic propellers as well as explore new method of propulsion for drones.

Our design uses a centrifugal fan design inspired by Samm Shepard's "This is NOT a Propeller" video where he created a centrifugal fan for a radio controlled plane. We were able to design a fan that has a peak output of 550g per fan that is safe when crashing and when the impeller inside damaged.

The chassis and fans are made of laser-cut polystyrene and is powered using brushless motors typically used for radio-controlled helicopters.

The drone uses an Arduino DUE with a custom shield and a PCB to control the system via Electronic Speed Controllers. The drone also has a feedback loop that will try to level the drone using a MPU6050.

We were able to prove that this method of drone propulsion is possible and is safer than using hard plastic propellers.
