CrazyChoir

Website | Installation

CrazyChoir is a ROS 2 toolbox allowing users to run simulations and experiments on swarms of Crazyflie nano-quadrotors. CrazyChoir implements several tools to model swarms of Crazyflie nano-quadrotors and to run distributed, complex tasks both in simulation and experiments. Examples include task assignment, formation control, and trajectory tracking settings.

Requirements and Installation

CrazyChoir requires ROS 2 Foxy to be installed on your system.

Some preliminary steps are required to complete the installation. We refer the reader to the installation guide.

Examples

To check the installation and start to use CrazyChoir, you can run

ros2 launch crazychoir_examples formation_webots.launch.py 

This will start a Webots simulation with 4 Crazyflie nano-quadrotor performing a leader-follower formation control task. A video of the simulation is available here:

Note: The example was executed on a Dell XPS 15 9570 equipped with an Intel i7-7700HQ CPU and an NVIDIA GeForce GTX 1050 GPU.

You can also run more advanced examples, such as the letter formation task, or the task assignment experiment. For more information, please refer to the examples page.
