In the above images you are able to see the robot navigate the environment using an occupancy map created from lidar scans. Frontiers are detected in the occupancy map and clustered, each cluster displayed as a different colour. Lastly, the green path is displayed in front of the robot which it follows.
This repository has been tested with ROS 2 Jazzy and Gazebo Harmonic. You can use this ros_docker repository for a simple docker container with those installed.
With this repository in your ROS 2 workspace, run these commands:
colcon build
ros2 launch navigator_bot_bringup diff_drive.launch.py
