Tutorials on how to modify flight control software packages to meet your own research needs.
A very short tutorial on how to set up an OrangePi (you can use any single board computer like RaspberryPi, in fact, any computer running linux) to play a specific mp3 file on boot. It is convenient if you always need to play this audio file and you want it to play as soon as
This is a short video documenting our recent progress on aerial manipulation. We used PX4, ROS and Optitrack to achieve autonomous perching using a simple quadrotor. https://youtu.be/XjAHYiE-JD4
This article discusses my undergraduate thesis project, working on flying drones with latency
In the last tutorial we have set up the ROS environment to use MAVROS to talk to PX4. In this tutorial we will run a small example program to autonomously hover a simulated vehicle. Simulation First! We highly recommend you to try this program in simulation first, for safety reasons :) Start a PX4 simulation,
Companion computer is a very efficient way to control your PX4 vehicle in off-board mode. We have tested various methods and we have concluded Robot Operating System (ROS) is the best way. Here is a series of tutorials guiding you to achieve off-board control. What you need: A Pixhawk or a Pixracer A Raspberry Pi
In the last post we have set up the PX4 source code for our new flight mode, the flip mode. In this post I will continue finishing the flip mode by creating a new application in the firmware, which commands the attitude during the flip. 1. Create the flip_control application Creating a new application in
Here’s how to create your own, shiny ARM gcc cross-compile toolchain for your Mac.
If you have programmed Ardupilot and now you switch to PX4, you would really appreciate how easy it is to implement a new flight mode in Ardupilot... PX4 is really good if you just want to write an App to do something, but implementing a new flight mode actually requires a lot of digging around
There are two ways to analyze your PX4 flight as I know, the ".px4log" file generated by PX4, and the ".mavlink" file generated by QGroundControl. 1. ".px4log" with FlightPlot The ".px4log" format is the log file format stored onto the SD card by PX4. The application that performs this logging is "sdlog2". The log files
In most cases, Software In the Loop (SITL) is sufficient for testing your flight controller code. But in other cases, you may want to use Hardware In the Loop (HITL) simulation to validate that your code can actually run on a controller board. The HITL differs from SITL in a few ways: All sensor raw
