Our goals  Meet minimum contest guidelines with ability to expand  Stay within budget Balance the capability of our team with the capability of what we throw together

Contest Guidelines  At a minimum: Meet safety guidelines Flight waypoints autonomously Identify the location of objects on the ground  Additional goals: Takeoff and land autonomously Identify the location of objects on the ground in real time

Autopilot  Hardware and airborne software from the Paparazzi project Open source software and hardware plans Wide range of features ○ Complex flight plans ○ Extensive data reporting Expandable hardware ○ Including sensors for autonomous takeoff and landing Adequate safety features

Autopilot  Paparazzi fills a niche market and isn’t officially supported by anyone - documentation was a problem  I spent a lot of time: Reading available documentation Browsing code base and schematics Talking to developers and users

Talking to the Ground Station  Programs can communicate via the Ivy software Bus  Turned out to be as easy as described, and programming errors we make won’t crash the plane  More information is available than anticipated, including  GPS location  Plane attitude  Servo positions

Video Control  We control the camera servos from the ground Custom circuit and code Errors we make won’t crash the plane  Using information from the GCS we can calculate the location of objects we see Camera servo position Plane attitude GPS location Altitude
