Installation

clone repository

git clone --recursive https://github.com/aurelappius/PX4-Autopilot

install dependencies by running

sudo ./Tools/setup/ubuntu.sh

also install ROS2 humble. see: https://docs.ros.org/en/humble/Installation.html)

Run the Simulator

Set up your workspace the following way by cloning raptor: https://github.com/raptor-ethz/raptor.git and this repository in the following file structure:

simulator
├── raptor
└── PX4-Autopilot

source the workspace

source /opt/ros/humble/setup.bash

build the raptor package by running:

colcon build

change your directory to PX4-Autopilot

cd PX4-Autopilot

source the raptor package with the following commmand

. ../install/local_setup.bash

run the simulator

make px4_sitl gazebo_raptor__baylands

the first (here raptor) is the model that is loaded and the second (here baylands) is the world.
