Open-source (GPL) autopilot on RC Plane Autopilot-Tiny v2.11 RC Plane-Multiplex FunJet Create project handbook Contains step-by-step simplified details necessary to recreate project in less time Understandable to the average engineer Assist two Aerospace Engineer teams These AEM teams handle the physical planes We help with all necessary electrical needs
3
FunJet plane requires configuration of a number of components AutoPilot Control Board Battery Radio-modem and antenna GPS receiver IR sensors for X-, Y-, and Z-axes Motor and controller RC receiver and antenna Servos International Traffic in Arms Regulations (ITAR) Open-source (GPL) necessary to be able to sell in international markets
4
Many types of commercial and enthusiast autopilots available Paparazzi already deployed on FunJets as well as other airframes Not well documented Paparazzi Wiki Useful for general info Fails to provide some specifics
5
Successfully fly* the Multiplex FunJet under autopilot control (uses elevons) After flying FunJet, fly aircraft with traditional configuration (ailerons, elevator, rudder) * Successful flight test entails manual takeoff and landing with autonomous flight by wire controlled by a PC ground station
6
Aerospace Engineering teams support We need to assist these two teams with any electrical or software related difficulties they encounter Manual Professor Hammer would like to have a detailed handbook that walks through the process Stretch goals Autonomous takeoff/landing Video/Picture feedback Multiple aircraft flying simultaneously Build/Fly our own FunJet

Paparazzi Augmented R/C Functional Diagram
10
Tiny v2.11 becomes the heart Everything is directly connected R/C receiver is auxiliary communication Serves as backup communication device
11
Manual R/C control Takeoffs Landings Modem failure Tiny v2.11 control Autonomous flight (Auto 2) Semi-autonomous flight (Auto 1) Fly by wire (air) through GCS
12
Majority of budget spent on pre-crimped wires Pre-crimped wire ~$30 per plane Crimper would cost ~$250 if bought separately The connector, 3-8 pin, cost ~$5 per plane Parts provided by Lockheed Martin Multiplex FunJet ~$75 IR sensors ~$70 RF Modem ~$200 Servos/receiver~$80 Motor/ESC~$110

10/11 – FunJet manual flight 10/25 – FunJet autonomous flight 10/25 – Trainer manual flight 11/2 – Trainer autonomous flight 12/8 – Implement advanced features Camera Interface paparazzi with AEM flight simulator 12/8 – Final draft of Paparazzi Handbook
14
We are making good progress towards our autonomous flight goal Most electrical issues have been dealt with We are learning
