ROS Nodes and Gazebo
This section demonstrates how to integrate the ROS nodes you created in the “Python to ROS” section with Gazebo simulation environments. By using pykal.gazebo wrappers, you can test your control systems in realistic simulated environments before deploying to hardware.
“Example: Turtlebot Gazebo Integration” shows how to modify the Turtlebot ROS node architecture to interface with a Gazebo-simulated Turtlebot, including topic remapping and simulation-specific configurations.
“Example: Crazyflie Gazebo Integration” demonstrates integrating the multi-sensor Crazyflie system with a Gazebo physics simulation, handling simulated IMU, position, and velocity data.
