Need SLAM based navigation step by step guidance
Hello, I am very new to ROS and SLAM. I am developing a wheeled robot that should navigate autonomously. For that, I am using SLAM. I need to know all the steps needed for that. Although I have created the 3D map using Intelrealsense D415 and RTABMAP package. But now my question is how I proceed further means steps needed to navigate in this 3D map. How I get sensor data for navigation. Any book, weblink, and help will be appreciated. Note that I need to apply all these to a physical robot. Thank you
The
Nav2 stack- link would be good if you first get good enough with ROS 2 (by doing tutorials from ROS 2 Galactic documentations).
