What Is ROS2? - Framework Overview

Let's look at what ROS2 has to offer when programming robotics systems. We will take a dive into ROS version 2 features, and go over some points on why it succeeded ROS version 1.

I love that the subscribe button lit up when you were talking about publishers/subscribers (2:36), that's so cool!

[@GeorgeLenoHolmesJr]

This is the best video I've seen on ROS2, well done.

[@spaghettiman512]

The video is very well made and extremely easy to understand!
Sad that this was not more popular.

[@souravsharma6092]

I normally don't comment but this video is really well made. It will be great if more videos on different concepts come up.

[@dontolley1738]

Thank you for the clear description of ROS2

[@juanmamix]

i never subscribe to a channel by only seeing one video, but that was so well explained and i liked a lot, hope you continue doing this kind of videos!

[@ayoubshadi2907]

Thank you ! Very concise and easy to understand (with some ROS background for myself)

[@pritvarmora2036]

It the Best video I have ever seen , Its explaining it very clearly

[@mums2109]

What a great ros video! Thank you!

[@BDEvans]

Brilliant video. Well done.

[@qwerty.760]

Amazing explanation!

[@hasanosman2618]

great explanation, thank u❤

[@sisami2109]

Superb video, thank you!

[@wombatillo]

Been waiting for someone to be concise, informative and sufficiently professional about a quick ROS2 introduction. I think you pulled it off very well. *It was actually such a good introduction that I went and bought the ROS2 in Python udemy course. Will let you know how it goes.

[@markgoproductions]

It's been almost a year.... how's it going?

[@fawadkhan8905]

@wombatillo would you please reply back?

[@MrMagic1885]

Hi, I'm currently trying to learn ROS2 from their official website however it is very content heavy with little practices to try out what we've learnt. May I know which Udemy course did you purchase and if how are you finding it so far? Thank you so much

[@AnasHawasli]

Dude this is Gold

Awesome video! Thanks

[@MetalRobotics]

amazing explaination!

Really, really good.

[@alinoorrahmansakib6687]

great content

[@mo.samhar8774]

شرح أكثر من رائع ... شكراً لك

[@10tronic]

Very clear. Do you have a video explaining the differences between ROS and ROS2?

[@milind-9683]

Awesome!

[@JustinSalbato]

Hi Raymond. Great video! What software are you using to create the animations for the video?

[@nvs502]

great explination

[@MatchaMakesThings]

THank you very much!

[@realredspry]

excellent

[@mayankmukesh2333]

Amazing

[@Bulbasauros]

nice video

[@m2tdev]

thanks

[@berenedain8427]

Amazing, very informative precise video. If it's not a secret, what software did you use to make the video/animations?

[@raymond-andrade]

I used Camtasia for video editing / green screen keying and used Blender to make the robot animation.

[@CaptZenPetabyte]

How is publisher/subscriber different to mqtt, and server/actions different from node-red please?

[@simonrism]

Dear Raymond,
Hope you are doing well !!!
your videos are really helpful. I got lot of knowledge from your educational videos.
However, I am trying to send data from VMware, Ubuntu 22.04 to esp32 board over wifi by using ros2. ESP32 board is already connected to Wi-Fi router. But, I was not able to send data from my PC to esp32 board.
Could you please help me little-bit?
Thanks, Simon

What’s the best platform for finding useful packages?

[@raymond-andrade]

Honestly, one of the easiest ways is to go on GitHub, and search "ros" followed by the topic you are interested in, than sort by number of Stars the repo has. Two of the most popular/useful packages imo are robot_localization and ros-planning/navigation.

[@zombieregime]

Isnt that communication scheme just MQTT, except maybe without the broker?

[@callmerel2809]

i think so too

[@marwanzaghloul6065]

are you going to update the ROS c++ devoloper course to ROS2

[@raymond-andrade]

I will be creating a separate ROS2 C++ course, which should hopefully be out by the end of this month. I want to keep the ROS1 and ROS2 courses separate, since there are tons of legacy ROS1 systems which work well for their application, and may not benefit much from a complete ROS2 overhaul.

[@marwanzaghloul6065]

@@raymond-andrade nice , i am waiting

[@kerron_]

Very difficult to work with but its the future

[@raymond-andrade]

I can definitely attest to liking the software flow of ROS1 in Python/C++ better than ROS2, but that is kind of expected when going from a centralized development environment (ROS MASTER) to decentralized DDS communication.
Although hands down the need for ROS2 with many robotics projects is very high, and helps keep systems resilient in the event of any network disruptions (especially for outdoor/swarm robotics)

[@dabara2004]

So I suppose I should go and learn ROS2 directly then rather than starting from ROS1?

[@kerron_]

@@dabara2004 research the difference conceptual wise and just go with ROS2

[@HOOHA333]

​@@raymond-andradeOK but why it is expected going from centralized to decentralized architecture
