Open-Source UAV

Introduction

• UAV is an Unmanned Aerial Vehicle• Our goal is to setup two different

plane configurations with Paparazzi autopilot and fly them autonomously

• Do this in conjunction with two separate Aerospace Engineer teams

• Create a handbook detailing simple recreation of this project

BETTER PIC THAN THIS

The Planes

• Multiplex Funjet– Elevons only for

pitch/roll control– Other difference

• Multiplex Minimag– Traditional rudder

and elevators for pitch/roll control

– Other difference

Paparazzi UAS

IMPROVE THIS PICTURE

Cable Work

• Creating proprietary cables– Bootloader cable: USB to 4-pin on Tiny– USB Programming cable: USB to 7-pin on Tiny– GPS Programming cable: I don’t even know– Power cables: As necessary

Sensor Modification

• Autopilot supplies 3.3V instead of 5V expected by IR sensors

• With a 3.3V source, the IR sensor gains are offset by ~1.5

• This presents saturation problems while in high IR contrast locations

• Replace resistors for unity gain

GPS Setup and Functionality

• U-blox software used for initial GPS setup• UAV software uses GPS for speed, location,

elevation• Real ground level needed for altitude

conversion from elevation

• <screenshot>

Ground Control Station/Modem

• GCS uses independent modem to interface with aircraft

• GCS controls aircarft through notebook PC

• Can be overridden by manual R/C control

Test Flights

• Pictures and details of the more important test flights we held and their results

Summary

• We got them both to fly autonomously?• Yes into a field… ROFL OMG LOL• Blah blah I have no idea what to say here
