  1. Open-Source UAS

  2. 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 Paparazzi enables a UAS package to be sold internationally without limitations from the International Traffic in Arms Regulations (ITAR)

  3. Airframes • Multiplex Funjet • Elevons only for pitch/roll control • Rear-mounted electric motor • Used by both AEM teams • Multiplex Minimag • Traditional rudder and elevators for pitch/roll control • Front-mounted electric motor • Used by AEM Team B

  4. Overview of Generic RC Airframe IMPROVE THIS PICTURE

  5. Cable Work • Creating custom cables • USB Programming cable: Direct USB connection to autopilot • Cables utilizing FTDI cables (USB – Serial converters) • Bootloader cable: Serial connection to autopilot • GPS Programming cable: Serial connection to GPS • Power cabling

  6. 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

  7. 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

  8. 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

  9. Test Flights • Pictures and details of the more important test flights we held and their results

  10. Summary • Both teams were successful in demonstrating autopilot functionality • AEM Team A achieved limited functionality with their FunJet • AEM Team B achieved full autopilot functionality with both of their airframes

  11. Our Team • Kevin Oberg • Dustin Douglas • Shuohan Wan

  12. Acknowledgements • Special thanks to: • Lockheed Martin Corp. engineers Reid Plumbo and Todd Colton • AEM Professor Hammer • AEM project teams A & B
