40:21 I'm totally new to ROS. I didn't understand everything, but it was still extremely helpful. I find that some open-source projects are excessively difficult for beginners to get into just because all the "old hands" expect you to know decades of history and can't understand why a beginner would be confused. Explaining the changes from ROS1 to ROS2 makes it a lot easier to identify where instructions and tutorials no longer match up and why, and helps me get a feel for some of the history of the project.
I’m an university student and I program in ROS from 2 years. It is a very good video to taste the changes before reading the full documentation. Thank you a lot.
I have been working on ros 1 for the past year and was planning to switch to ros2. This was a really concise video about ros 2 and I appreciate your effort. Watching at double speed with subtitles, was surprisingly understandable.
This video made things a lot easier to understand. I'm new to ROS and i started with ROS2, but i would like to know what ROS2 added on ROS, why was it developed, etc... So this video was very usefull. Thanks a lot, keep up with the good work you have been doing :D
Really, you explained everything magnificently, and as it's my first time using ROS, it took me about 8 hours to understand everything. Thank you. But I want to know your opinion on the updates regarding plugins and documentation in ROS2. Also, is ROS1 considered obsolete, or is it still supported?
Thank you! Now ROS 2 contains all the important plugins, also from next distribution (May 2024) it will also use the new Gazebo by default. From 2024 onwards I recommend that you only use ROS 2 for any new project. ROS 1 is not obsolete yet, will be in 1 year. But only use ROS 1 if you have to work on an existing legacy project.
I started with Ros 1, now I will upgrade Linux and continue with Ros 2. I am a 4th year university business administration student, I do not have a field to use, but it is very enjoyable to learn. I am interested in data science, will I need it in the future? Do you think I should further your learning?
I have never used ROS before and I'm running windows on my computer. However I noticed that Linux is used in most tutorials. So I was wondering; is there a big difference using Windows over Linux? If so; are there any resources that would help me get a clearer idea on the differences?
Linux is usually preferred by a lot of people when it comes to software development, because it makes things more convenient, you have a lot of useful tools etc. To use ROS I would suggest to create a dual boot on your computer to have both Windows and Ubuntu. And unfortunately there are not so many online resources about ROS and Windows :/
Not really, as far as I know. You can find many alternatives to do some parts of your projects (ex: different platforms like Arduino, different ways to communicate like MQTT, tools like Node Red), but for a complete middleware with all the capabilities in ROS2, not really.
Dear Edouard, I want to follow your Udemy Course ROS Actions to improve myself. However in course description you outlined that "this course targets the first version of ROS, or ROS1. This is not a ROS2 course." I only learnt ROS2 so far, and no ROS1. Do you still advise this course to me? It would be unlucky to learn ROS1 complex actions if I cannot use it in ROS2. Thanks for your answer in advance.
The core concepts are pretty much the same in ROS1 and ROS2, so if you understand ROS1 Actions you'll be fine with ROS2 actions. The biggest challenge will be to learn the new syntax, but this is not too difficult. I'd say that with the ROS1 Actions course you are 70% ready for ROS2 actions. Note: I'm preparing a new course that will include ROS2 actions, this course will be released probably during September 2023, so if you can wait 2 months then I have the perfect answer for you.

Being completely new to ROS, I can't stress how much this overview video helped me for my current ROS research. Thank you for uploading this gem! (:
Thank you for the video sir! Very clear explanation for someone coming from years of ROS1.

Very well explained. Thank you for all your contributions.

wow! such a well organized presentation, thank you so much
Thank you. Very effective communication style.
thanks for everything. it was a absolutely clear explain.
I've taken the ROS2 to ROS1 developers and I highly recommend it. This video is also a nice complement. Thanks for sharing your knowledge.
Thank you for your video, it provides a concise explanation of the topic!
Damn this is very clear. I now know what to do for my new research project after watching this
thank you! 3hours of excellent content.🙂
Very clear explanation 👌
This is very helpful thank you
Nice clarification for the differences between ROS 1 and ROS 2.
You did a so nice explanation that I've just bought your courses on udemy! Thanks!
Excellent video. Subscribed and following
very good explication thank you
Very good video, thank you for it!
Great video! Thanks!
Really great video!!
Very nice explanation! Congratulation a thank you for sharing!
Brilliant explanation!
Great tutorial! Thanks💯

If you plan on working with robotics, then yes! For data science I'm not sure ROS 2 is the best thing to learn.
Great video.

@@RoboticsBackEnd thanks
As i remember ros melodic build with gcc 7.5. Does it mean that if it is needed i can use c++ 17 with ros melodic because of ABI competibilty ?
Hi, is there any strong competitors for ROS, alternative middleware that is in the same league as ROS?
Not really, as far as I know. You can find many alternatives to do some parts of your projects (ex: different platforms like Arduino, different ways to communicate like MQTT, tools like Node Red), but for a complete middleware with all the capabilities in ROS2, not really.

magnifique existe il un autre bouton pour maitre un autre pause 😅

@@RoboticsBackEnd thanks for the answer. I think you just released Ros2 for beginners Level2. Going to check it hopefully soon
Nodelet.... component.... does Rust really need to redo threads and libraries? Rewriting abstractions is kinda irritating.
good
👏👏👏👏👏👏
