This platform overview video shows quadrotors in flight, fixed wing hardware in the loop simulation and a novel experimental aircraft. It also introduces all PX4 hardware modules (available from 3D Robotics).
This is the second of a series of PX4 introduction posts. The first is here. We will continue our coverage in the next days with an introduction to first-time setup and calibration and installation of the programming environment (Eclipse or plain shell, arm compiler, USB flashing and/or JTAG debugging).
