3 MQ-9 Reaper err.. “Predator” Credit:

4 UAVs and Autonomous Technology Autonomous – “Self-governing. Governing independently” – No human intervention – Medium to large aerial systems generally have the highest levels of autonomy of any robots Environment Sensing Navigation Source:

5 The Market Place MicroPilot Procerus Unav Cloudcap Technology AttoPilot FlexiPilot/EasyUAV Paparazzi UAVDevBoard ArduPilot Cheap >>> Expensive BMW >>> Custom Build More Info: Google keywords

6 UAV Essentials Flying – Stabilization – Thrust/Lift > Drag Navigating Operating Payloads – Sensing (visible, IR, etc.) – Sniffing (say , air samples, misc. RF) – Transmitting (RF, lasers) Lift Thrust Drag Weight

7 Infra-Red Sensors – Really cheap! ($40-60) – Easy to use – Not very effective in blizzards, dense fog, extremely mountainous terrain.. IMU, Inertial Measurement Unit – Becoming cheap ($80-$200) – More complex – Can be internally enclosed in airframe – Effective in all weather, terrain conditions Stabilization == Wings Level Please

8 Thermopile based approach CoPilot Flight Stabilization Sensor Source: _Operation

9 Servos Source:

10 ArduPilot “The $25 Autopilot” Based on the popular Arduino microcontroller. Created by Jordi Munoz with support from Wired Editor-in-Chief Chris Anderson Sold at Community based at

11 ArduPilot Shield Provides Airspeed, other function. Purchase at store.www.DIYDrones.com

12 System Overview – ArduPilot v2 Source: ArduPilot Manual v2

13 ArduPilot System Integration Source: ArduPilot Manual v2

14 Source: ArduPilot Manual v2

15 ArduPilot Config Tool Created by the DIYDrones.com community to upload course information easily! Source: ArduPilot Manual v2

16 Telemetry Zigbee ( ) radios used for telemetry data 915 MHz is best Xbee Pro 900 XSC RPSMA with proper antennas get mile range Go with RPSMA connectors! Breakout Board Vendors: Antenna Vendors:

17 Video Feed Cameras – Board Cameras are cheap, small, light, have decent quality Transmitters – Tough Selection for good distance.. – Have to have Ham Radio License to use good bands – 900 Mhz is good but interferes with other systems – Roll your own! Recommend 434 Mhz with filters for harmonics or 1.25 Ghz ATV bands Cameras: Search “Board Cameras” Tx/Rx Systems: License: $12-14 for Ham Test! Do it!

18 GPS Must-Have system for positioning data High update/refresh rate Getting smaller, cheaper, easier to use GPS:

19 Air Frame Foam is best! – Cheap – Easy to fix (Gorilla Glue mixed with water will foam to make a great bond) – Easy to work with (exact-o knife = golden) – Can Tape Together! (Scotch and Packing Tape) – Durable (Landed in a tree in front of the hotel..)

20 Air Frame of Choice Ladies and Gentlemen, The Multiplex Easy Star

28 MOVIE TIME!!

29 Future Work ArduPilot Mega coming soon! – Follow at Diydrones.com – Push waypoint and course updates to UAV live – More processing power, options, bells, whistles Touch interface on Android phone for control Easier Configuration

30 Issues Legal Issues – Fly under Model Airplane Regulations Under 400 feet Within Line of Sight Have ability to take control (safety) RF Issues – Video Feed must been unencrypted if its on the Ham Bands, transmit your Callsign “Its not stalking if its Love”

31 Questions??
