Foldable quad for ROS integration experiments

I’m shortly going to work integrating the OpenPilot telemetry with ROS.

Main (long term) focus is indoor positioning and navigation.

This is a quick mockup of the craft that will be used. Plates are going to be rebuilt to better host everything

The reference platform  is made by

• OpenPilot Revolution flight controller;
• OpenPilot GPSV9 with integrated magnetometer;
• Control link using Revolution on board OPLink;
• ODroid U3 sbc hosting Ubuntu server 14.04 with ROS Indigo;
• WIFI card TL-WN722N (that uses an external antenna connected with a RPSMA);
• USB Web Cam, initially used for optical flow.
• Telemetry link using WIFI connection;
• Connection between Revolution and Odroid using USB.
• Sonar sensor for precise agl measurement
