Installation

ROS packages dependences:

• gazebo-ros

• mavros here

• mavlink
• geographic-msgs
• tf2-eigen
• control-toolbox

• GNSS_utils here

GeographicLib dependeces:

sudo apt-get install libgeographic-dev
sudo apt-get install geographiclib-tools

Run the script in: install_geographiclib_datasets.sh

Compile this directory in your ROS workspace.

Then copy the already configured files to the *mavros* directory:

cd ${YOUR_ROS_WORKSPACE}/src/heifu/heifu_scripts_firmware
cp apm_config.yaml $(rospack find mavros)/launch/
cp apm.launch $(rospack find mavros)/launch/
cp node.launch $(rospack find mavros)/launch/

NOTE: Adjust the yaml loader script to deal with the argument substitution in the roslaunch of yaml files:

cd ${YOUR_ROS_WORKSPACE}/src/heifu/heifu_scripts_firmware
cp loader.py /opt/ros/melodic/lib/python2.7/dist-packages/roslaunch/

Dont forget to add gimbal and mavros to the source folder and run catkin build

To run the nodes with a real drone:

Just launch - Heifu_bringup

roslaunch heifu_bringup heifu_bringup.launch

Launch Input arguments:

    argSafety - Activates the safety zone mode and run the node heifu_safety.
    argTakeOffAltitude - Defines the Takeoff altitude.
    argSim - Activates the simulation mode. Loads Gazebo and a pre-configured world with the drone HEIFU.
    argSecredas - Activates the Secredas Usecases. (Needs extra packages secredas).
    argUseCase - Defines witch usecase of Secredas will be loaded.
    argPlanners - Loads the Planners nodes with static colision avoidance (Needs extra packages Planners).

Heifu Simulation:

First make sure that the ArduPilot firmware is correctly installed, by following the steps described https://gitlab.pdmfc.com/drones/heifu/wikis/Install-and-Configure-ArduPilot-Firmware.

To open the simulation:

1st terminal - Launch Heifu_bringup

roslaunch heifu_bringup heifu_bringup.launch argSim:=true

2nd terminal - Launch ArduPilot firmware

cd ~/ardupilot/ArduCopter/
sim_vehicle.py -v ArduCopter -f gazebo-heifu -I1
