Structure
Condor I, a large quadrotor airframe with a very modular rack-like cargo area.
All with parts from the hardware store.
Controller
The flight controller is the nervous system of a drone, keeping it stabilized and in the air.
Based on available off-the-shelf components such as the Teensy 3.1 microcontroller and Adafruit 10-DOF sensor board, this controller is trivial to build (hence the name, trifle).
*Note: the custom controller project is currently stalled, it is recommended to use the PX4 Autopilot. Modifications to the underlying real-time kernel, NuttX, have been merged back upstream.
Cockpit
No remote control needed.
The drone is guided from a computer through a telemetry link. Current state is displayed in a modern web-app and controlling is done via a gamepad.
