Assembly and flight test 6-28

    Three UAVs, named Crush, Pumba and Hathi were assembled for this research in June. Main hardware specs was: PX4 autopilot, 3DR ublox GPS, 3DR telemetry and Quad Frame Kit.

     QGRoundControl and APM Planner 2 were mainly used for sensor and radio calibration.

     After two busy weeks of soldering, assembling, studying Ubuntu operating system, ROS Hydro Medusa, and PX4 autopilot firmware programming, all three drones were ready to fly! A team of five people, Gita, King, Casey, Patrick and me took the flight test on on a soccer filed in UC Berkeley.

      Casey's turn for controlling:
                                      

      Last but not least! :)

     To summary, quadrotors are not easy to control for beginners since acceleration is controlled instead of position. Plus, the time delay or the disturbance of wind turbulence would make it even worse. However, after practising for a certain time, controlling becomes much easier.
