dRoninFlight/dRoninPublic

What is dRonin?

An advanced autopilot and flight controller firmware for multirotors, planes, and helicopters.

What does dRonin do?

dRonin is a comprehensive flight controller firmware derived from the OpenPilot and Tau Labs architectures. It is engineered to stabilize and navigate a wide spectrum of unmanned aerial vehicles (UAVs), including quadcopters, hexacopters, fixed-wing planes, and traditional helicopters. The firmware offers production-ready flight stabilization, featuring an advanced autotune system that automatically calculates optimal PID and LQG (Linear Quadratic Gaussian) control constants. It supports a broad range of hardware targets and is designed for diverse applications ranging from acrobatic drone racing to autonomous waypoint navigation.

Who is dRonin for?

dRonin is for drone hobbyists, FPV racers, and aerospace researchers who require a flexible, highly stable, and open-source flight controller for custom UAV builds.

• Multi-vehicle support: Capable of stabilizing and controlling quads, hexas, planes, and traditional helicopters.
• Advanced autotuning: Automatically calculates optimal PID and advanced LQG control constants for highly stable flight characteristics.
• Broad hardware compatibility: Fully supports a wide array of flight controller boards, including BrainFPV, DTFc, and Quanton.
• Autonomous navigation: Includes features for programmed waypoint following and GPS-assisted flight modes.
• Flipover mode: Includes specialized recovery algorithms to flip a crashed vehicle back upright using motor bursts.

   Hello world: it's time for another dRonin release, of our "inconceivable" development effort. There's exciting stuff in here, including the first flight-ready LQR control system (no longer are we stuck only with PID!) Jump ahead to: Changes / Errata & troubleshooting **Major changes since last release:** As always, there's many small bug and usability fixes. But beyond that: * Core controls and functionality improvements: * **LQG (Linear Quadratic Gaussian) control added as an alternative to PID**. To use, autotune and then configure LQG or LQGLeveling flight modes. * Increased maximum yaw axis PID limits, as some real crafts with small propellers were hitting them. * Introduced ability to limit the maximum speed commanded from individual motors (i.e. artificially limit kV to run 4S motors on 6S) * Ability added to specify thrust mode separately for each stabilization bank * Improvements made to control input smoothing/interpolation * Autotune now calculates hangtime and vertical / altitude hold control constants * **Flipover mode** * Drives motors on one "edge" to flip the vehicle back upright * "To configure, configure a quad with 3D out
