ROS NAVIGATION IN 5 DAYS #1 - Course Overview & Basics Concepts

What is the ROS Navigation Stack? What do I need to work with the Navigation Stack? In this tutorial, you will find the answers and get an overview of the ROS NAVIGATION IN 5 DAYS course.
💻 Useful Resources:

What you'll learn from this video?
* What is the ROS Navigation Stack?
* What do I need to work with the Navigation Stack?
* What is the move_base node and why it is so important?
* Which parts take place in the move_base node?

Overview:
The objective of this course is to give you the basic tools and knowledge to be able to understand and create any basic ROS Navigation related project. You will be able to create maps of environments, localize the robot in the environment, make the robots perform path planning, visualize data of the different Navigation processes, debug errors using RViz and configure the different Navigation nodes.
The course will allow you to understand Navigation packages that others have done. So you can take ROS code made by others and understand what is happening and how to modify it for your own purposes.
This course can serve as an introduction to be able to better understand the official ROS Navigation documentation or external Navigation documentation and projects.

I don't remember how many times I come back to watch this video again, and how many times I recommend this video to our teammates.

Congratulations on the tutorial. Just started to study the navigation stack and I will definitely follow the course unit by unit. Thanks!

Is it possible to get the codes for the various files for this course?

[hessel]

Hello beginner here, is it also possible to create a map and the let the robot figure out where it is on the map? This way would be more accurate right?

[ismailguenniche]

hello,
thank you for the video!
I have a question. How do i close visual studio so i can see les fichiers like you have

[kshitijkumarjaiswalietluck]

while running the command in my pc
RLException: [gmapping_demo.launch] is neither a launch file in package [turtlebot_navigation_gazebo] nor is [turtlebot_navigation_gazebo] a launch file name
The traceback for the exception was written to the log file

help on this....

Hi, I had a query regarding the gmapping algorithm. So Gmapping is considered to be a SLAM algorithm but it only gives the map and does not publish any Localization message like Hector SLAM. Being a SLAM algorithm it should map and localize simultaneously which I don't see in Gmapping. Mostly I see people using AMCL for Localization. I'm not sure but the pose can be obtained using the tf since gmapping publishes tf between map and odom frame and for that separate node has to be written which fetches the data from map to the base link. So, is it appropriate to say Gmapping is only mapping algorithm and not SLAM? Please correct me if I'm wrong.

Hi, I am not sure about the package that I have to download for this tutorial

[preetiprasad]

Could you please tell what commands you are using ?

[malharjajoo]

Hello, very nice explanation and video tutorial. But I have a question, if I'm using 2/3 external cameras in stereo setup to obtain position estimate of a Parrot A.R. Drone, can I still use ROS navigation stack for Path Planning for drone ?

Is it possible to use ROS navigation with CARLA simulator?

[MrMytubevidmaker]

Im using namespaces and the I set the odom_frame_id in the amcl params to the $(arg ns)/odom, however there is still no particle cloud showing in rviz. Any idea what could be the issue?

[KoloOkolobiegunowe]

Hi,
thank you for the video!
I have a question. How do you create a new project and apply my obstacles and dimensions to it? Do you have an instructional movie?
One more question. Why is the LIDAR used in the example 180 degrees, not 360?

[arsalanwasim]

Salam, can i use all the commands on your tutorials in my actual workspace instead of using a virtual one because my internet connection gets stuck sometimes

[arsalanwasim]

How should i install gmapping in my own system, any tutorial or guide would be helpful

[ivanllopis]

It would be really good if you actually explain what the commands do. Because copy-pasting stuff isn't learning ROS Navigation, at all, everyone can do that and still have no idea what ROS is or how it works.
