Below are links to a wordpress site and youtube channel for Hyperion Robotics. We're currently working on a autonomous quadcopter that uses Raspberry Pi, Arduino UNO, and OpenPilot CC3D flight controller. All documentation is on the website, which is frequently updated with our progress. If you have any questions regarding the question, I'd be pleased to answer them.
