The recording of this course is part of the Programming for Robotics (ROS) Lecture at ETH Zurich:
www.rsl.ethz.ch/education-stud...
Lecturers:
Péter Fankhauser, Dominic Jud, Martin Wermelinger
Course 1 covers following topics:
- ROS architecture & philosophy
- ROS master, nodes, and topics
- Console commands
- Catkin workspace and build system
- Launch-files
- Gazebo simulator
About the course:
This course gives an introduction to the Robot Operating System (ROS) including many of the available tools that are commonly used in robotics. With the help of different examples, the course should provide a good starting point for students to work with robots. They learn how to create software including simulation, to interface sensors and actuators, and to integrate control algorithms.
Objective:
- ROS architecture: Master, nodes, topics, messages, services, parameters and actions
- Console commands: Navigating and analyzing the ROS system and the catkin workspace
- Creating ROS packages: Structure, launch-files, and best practices
- ROS C++ client library (roscpp): Creating your own ROS C++ programs
- Simulating with ROS: Gazebo simulator, robot models (URDF) and simulation environments (SDF)
- Working with visualizations (RViz) and user interface tools (rqt)
- Inside ROS: TF transformation system, time, bags - Věda a technologie

Very nice to know in a light way what Robot Operating Stystems is. I reccomend this video to everyone who has time, a little patiance and most impportant, interest in learning the subjetc with you are propably about to start working.
Nice job ! Congrats !
Brilliant prelude to my Robotic technicians course online at University of Houston in collaboration with George Brown college ,Ontario. Thank you Prof.Alberto Ezquerro.
Thanks a ton for this! Its a great refresher for my upcoming job interview
This is an awesome introductory lecture about ROS. Please keep posting more lectures.
the questions is, do I really need to learn ROS? is ROS used in the industry? my experience is "not really". Please name some robots or robotics companies who actually use ROS?
@@RobotixwithSina
- You can ask the same question for all the existing robotics frameworks. ROS is open source. It has a very large community. It has a lot of useful tools and packages. It supports many robots.
- My experience is that ROS is used in the industry more and more. There are a lot of companies that contribute to ROS 2. index.ros.org/doc/ros2/Governance/
- There are a lot of companies that use ROS in their projects and products such as Amazon AWS RoboMaker, Intel, Samsung, Matlab, Fetch Robotics, ApexAi, Clearpath, Robotis, Tier IV Autoware, ADLink, Rover Robotics, Locus Robotics, Freedom Robotics, etc. You can google these companies and learn more about their tools, software, and robots.
@@mlherdgn : Thank you Melih for your comment.
I get that a small number of companies may use ROS for maybe testing and automation, but not really for robot development. if you look at the list you provided, the majority are not really a company that develops a robot, they are more of companies who use a robot for automation, research, and testing.
but thank you for the info. what field of robotics are you working in?
@@RobotixwithSina Hello,can you tell me please what i need to learn instead of ros?
I have been struggling ROS since last couple of weeks. Everybody starts with installing and then some example also they have a title that it's for beginners :(
This the only session I have ended up is exactly for one who is really a beginner. After watching first half of the video I could connect dots.
Thanks to the whole team :)
can you say how did you install ros and using which platform(OS) to master ROS
The lecture was perfect how ever i am facing problems in installing the husky-simulator package(the one given in exercise) i am using kinetic distribution
Thank you very much for publishing these and so many resources!
idhr mujhe kuch samajh nhi aaya aur tu thanks bol rha hai....
Excellent course!! Thank you for uploading!

Excellent introductory videos. I learned a lot more today than in other videos.
idhr mujhe kuch samajh nhi aaya aur tu thanks bol rha hai....
This is such a helpful course. Thank you so much for uploading!!!
Congratulations for this lecture, thanks!
Thank you Prof. Fankhauser and ETH for these great lessons!
idhr mujhe kuch samajh nhi aaya aur tu thanks bol rha hai....
Hi, can you update the link for the slides. Excellent work btw!
are you guys alive ? please upload more content... thanks for help.
thnx for helping us .
Gracias MARTIN !!!
This is very useful, thanks !
Thank you very much!
what a nice course
This lecture series looks really good, but is it still relevant? I'm using the ROS Melodic build, which is later than Indigo. I assume that the majority of the stuff is the same, especially since in the ROS wiki tutorials it essentially says "yeah just replace the build in the file path with whatever build you have" so that tells me they're all similar. I just want to make sure though.
It is great!
Thank you for that excellent lecture
Thanks for sharing, it helps a lot :)

Great!
It's a well lecture about ROS. Thanks a lot. But When build the sample " ros_best_practice" , something wrong during building process. Then I found the problem: in my hydro distribution, std_srvs lack of Trigger.h file. so Could you tell me which distribution do you use now? Thanks again
You should use the Kinetic version of ROS.
i cannot find the world on ur website... nor do i understand what to do with the launch file
great learning experience
Hi, i have installed ros kinetic un ubuntu 16.
can I build the ros_package_templete on my system? Or does is run only on indigo?
after catkin_make (i dont have the tools) i get this error:

for 17:17, is there a rospy equivalent? I tried typing rospy but I'm not getting anything
It looks like the Ubuntu_ROS_Course.zip link is not working. Is there another way we can download this file?
it's available now
Help me out please?
in this video 33:25 , I entered "roslaunch ros_package_template ros_package_template.launch" but got ERROR: cannot launch node of type [ros_package_template/ros_package_template]: can't locate node [ros_package_template] in package [ros_package_template]
Thank you in advance
Did you build the package after you added the git files?
is it necessary to learn first the foundations e.g. kinematics, before learning ROS? Thanks a lot.
33:20 i do like you say, but i get a error when i try to launch that package: "ERROR: cannot launch node of type [ros_package_template/ros_package_template]: can't locate node [ros_package_template] in package [ros_package_template]
"
Have you solved it? Please share the solution
ROS is cool!
Thanku so much for posting :)
Good Morning
I am Javier Acosta, I am doing a project of Thesis with LINUX 16.04 and ROS in which I need a data acquisition card with analog and digital ports, it is not necessary to be high speed.
Could you recommend a data acquisition card preferably USB with which I can work?
I thank you for your help.
Sincerely
Javier Acot
Please how do we get access to the exercises?
when i try launch the smb_gazebo package from the given exercise, it throws this error:
when instantiating macro: LIDAR ..............
anybody have any idea whats going on?
One curious question. How the node structure of ROS is suitable for ROBOTIC applications?
Manisha Kad it almost solve all problem with node moduler approach
where can i get the zip file the link is working please tell me!!!!!!!!!!!!!!!!!!

i have installed ros kinetic, everything seems good other than catkin build command as it does not work. I have tried catkin_make which works but not sure if it will make any difference.
Try this:
sudo apt-get install python-catkin-tools
Thanks a lot
In case somebody was looking for the slides --> rsl.ethz.ch/education-students/lectures/ros.html
It looks like the slides link is not working. Is there another way we can download this file?
I was having the same issue. The slides were working a week or so ago and then poof the link stopped working. I did a google and found that one.
thanks! pls can u pls send this ROS software to me
I need a tutorial step by step of how to install openRave into ubuntu, please help!!!
What does it mean when you rosrun your package and the node but it produces Segmentation fault (core dumped)
?
why don't ros use more traditional names like session/ thread, instead of topic/node etc
Is this still up to date? :)

Hi Robotic Systems Lab, I have downloaded the Ubuntu_ROS_course virtual disk and used it on VMware, it runs fine, however, I have a little problem with the keyboard layout. For example, when I press the Z button it becomes Y and vice versa, I think it because this is Germany layout right? How could I change to US layout? Thanks for sharing the course
i didn't find the exercises in the website of the course sir!
U r welcome www.rsl.ethz.ch/education-students/lectures/ros.html
We have just updated the exercises on the course website: www.rsl.ethz.ch/education-students/lectures/ros.html
appreciated :)
Is it not compatible with the ubuntu 16.04?
Yes, it is compatible with 16.04. Are you facing any problems?
Is that zuckerberg talking in the end. Holy Crap.
Guys can someone tell me why ROS exists? I mean why it is needed. I am a mechanical engineer, but I need a real case to understand and get it clear in my mind. Can someone make an analogy to describe the ROS and its requirements for the robotics? What was the problem in the past so that they have created ROS? Thanks in advance
I see that this comment is 4 years old now. Do you still need an answer to this question ?
@@omaraissani6255 yes
+1
This is for ROS1 or ROS2?
I always say 'duh-vel', but here it is 'devil'.
Do you use ros with anaconda env. ?
As far as I know, Ros messes around with (I think) the file structure of Anaconda, so it might be best to only use one or the other on the same machine.
Correction -- this video explains how to make them work well together: czcams.com/video/EMF20z-gT5s/video.html

9:15
does ros work in windows ?
yes
13:30 oh no, our messages are compromised! :o
the identities of our undercover agents are revealed?! :S :S
and then a terminator came at 15:58... I'm outta here man... way too dangerous around here

I have made a github repo for the solution to each time's exercise. Please feel free to check. github.com/luym11/ros_practise
To be honest dont waste your time on watching these videos if you are a beginner. Because its advance level course. And he has skipped many basic things. the packages he has mentioned to to download and build are not working.
Thanks for your feedback, Muhammad. Is there anything specific you miss in this course for people new to ROS? Please keep in mind that this is a ROS course and not a programming course and we assume that participants already know how to program. Which packages are not working for you?
ros-kinetic-husky-simulator
@@sufyanraza5273 It's not working for me either
Technically perfect, but i am missing some enthusiasm in your voice. but who cares, great content...
boring tuts
