UFO Generation #4

Final Documentation

Written by : Ayaka Hatori (Project Manager) Overview Purpose of Project The UFO Ab-Ducted project aims to provide a safe to operate, lightweight, and durable flying object. There are many useful applications for such a product, including a camera mounted monitoring system to obtain an aerial perspective. The UFO will be stable and maneuverable via […]

PCB design – Battery protection circuit

Written by: Ayaka Hatori (Project Manager) As one of the requirements for our UFO, we will be building a custom printed circuit board (PCB)  for our battery protection circuit. Our lithium polymer batter does not include a built in protection circuit so we will be implementing that on a separate PCB. We will be following […]

Completed Project with Progress Update

Written by: Ayaka Hatori (Project Manager)   The team has been busy at work for the past three weeks, working relentlessly on the UFO and working on meeting all of its requirements. Here are the updates from each engineer as written by each engineer:   Catherine Sakurai (Manufacturing) Update 1: I made urethane foam mold […]

Rapid Prototyping-UFO

Written by: Ayaka Hatori (Project Manager) Our first prototype was constructing a propeller based quad copter so we could start working with PID tuning.     The picture below shows the team working on the final production model without the shell covering   The video below is one of our final test runs with the […]

Shell Molding

Written by: Ayaka Hatori (Project Manager) For our UFO, we are required to create a shell that give the entire craft the look of an unidentified flying object from the movie The Day the Earth Stood Still. For our use, we decided on a vacuum form molded Lexan plastic. But, before we reached this conclusion, […]

Electric Ducted Fans – Number of Blades TOS

Written by: Ayaka Hatori (Project Manager) There are many different blades available for the electric ducted fans. We were curious to see if the number of blades dramatically affect the amount of thrust produced.     We did a study on 3 blades and 10 blades and it was clear that the 10 blade fans […]

It FLIES!!

By: Ayaka Hatori (Project Manager) At last we have gotten our UFO up and flying! We ran into a few problems the past few weeks including connectivity issues and shorting out an ESC, but this week we received all of our replacement parts and got our UFO to fly with default PID coefficients. Take a […]

PID control and tuning

By Salvador Ceballos (Computer systems and control engineer) PID Background: To stabilize the UFO, Multiwii’s PID controller incorporates seven PID loops, one ‘P’ loop, and one ‘PI’. One for each spatial Cartesian axis (yaw, pitch, and roll) and one for altitude, one for auto level (auto correction), one for navigation rate and position rate. The […]

How to: Light Show!

Adafruit NeoPixel: Getting Started By Logan Webster This post is to give a quick tutorial to getting started with an Adafruit NeoPixel. Specifically we are working with the NeoPixel Ring of 24 LEDs. It has a Diameter of 2.5 inches, and 24 WS2812 Intelligent control LED integrated Light source. Below is the a link to […]
