Installation

This package has been tested with python3 in ROS2 Humble/Ubuntu 22.04 (recommended), ROS2 Jazzy/Ubuntu 24.04 and ROS2 Foxy/Ubuntu 20.04.

Dependencies

• Parrot Olympe 7.5.0 - SDK for Parrot drones:

  pip install parrot-olympe==7.5.0
  

  Troubleshooting

  ERROR: Could not find a version that satisfies the requirement parrot-olympe (from versions: none)

  Install the latest version of pip:

  sudo apt-get install python3-pip python-dev
  echo 'export PATH="~/.local/bin:$PATH"' >> ~/.bashrc
  source ~/.bashrc
  

  Command 'python' not found

  Set python3 as the default python version:

  echo 'alias python=python3' >> ~/.bash_aliases
  source ~/.bash_aliases
  

  TypeError: Expected a message Descriptor, got Descriptor

  Install protobuf version 3.6:

  pip install protobuf==3.6
  

  AttributeError: module 'collections' has no attribute 'MutableMapping'

  Install protobuf version 3.20.0:

  pip install protobuf==3.20.0
  

• OpenCV - library for real-time computer vision:

  pip install opencv-python
  

• SciPy - library for scientific and technical computing:

  pip install scipy
  

Note

To install Python packages using pip in Ubuntu 24.04, you can add --break-system-packages flag:

pip install --user <package_name> --break-system-packages

Build

To build from source, clone the latest version from this repository into your ROS2 workspace and build the package using:

cd ~/ros2_ws/src
git clone -b ros2 https://github.com/andriyukr/anafi_ros.git
sudo chmod -R 777 anafi_ros/
cd ..
colcon build
source install/setup.bash

Troubleshooting

SetuptoolsDeprecationWarning: setup.py install is deprecated. Use build and pip and other standards-based tools.

Install setuptools version 58.2.0:

pip install setuptools==58.2.0

Usage

Important

Remember to update the firmware of the drone and the SkyController.

Tip

• To update the firmware of ANAFI 4K and Thermal, use FreeFlight 6 app for Android or iOS.
• To update the firmware of ANAFI USA, use FreeFlight 6 USA app for Android or iOS.
• To update the firmware of ANAFI Ai, use FreeFlight 7 app for iOS.

To connect to the drone, run in the terminal:

ros2 launch anafi_ros_nodes anafi_launch.py namespace:='anafi' ip:='192.168.53.1' model:='ai'

where

• namespace is the namespace for this specific drone, it is used to connect to multiple drones;
• ip is the IP address of the device to connect, it has to be
  • '192.168.53.1', for connection through Skycontroller (recommended),
  • '192.168.42.1', for direct connection to the drone through WiFi,
  • '10.202.0.1', for connection to the simulated drone in Sphinx;
• model (ignored, when connecting through Skycontroller) is the model of the drone, it has to be '4k', 'thermal', 'usa' or 'ai', depending on the drone model you are connecting to.
