Simulating Robots with Gazebo and ROS | Getting Ready to Build Robots with ROS #8 

Hi Johs, you are doing amazing tutorials, there are no such content across the whole youtube!

You are a godsend, thank you for creating content for the robotics community!

You are the light of my ros

Your videos have really accelerated my project. Looking forward to the ros2_control video!

Many thanks for your clear and detailed explanations. Great job!

Awesome video, thank you very much for creating such great content!

Best tutorial for Ros Gazebo on internet...!

From Korea, thanks for very nice video . Thank you!

It was awesome. I am really looking forward to your next videos.

Thank you!!! very inspiring.. love the tutorials!

Thanks for the tutorial and amazing sharing . You explain way better than mine lectures.

This bro saved my life.

Exactly what I needed thank you!

Great video...would like to see a video on explanation of controller and hardware interface code... Thank you.

Suuuuperb video, Thank you!

Great content

Hello, it would be very useful, if you could make a video explaining ROS and ROS2 because I'm a beginner here and don't understand much of it. Thanks!

great camera quality on this one

Great video, thank you. Though I might ask for some help - using ros2 and Homble, trying to synchronize between Gazebo and Rviz and cant transfer the use_sim_time to the controller nodes. any Ideas? thanks

humble tester :) I ran into some issues today. Both ROS Humble and Gazebo Fortress are working well enough that I can follow along with your lesson. However, upstream gazebo does not seem to be building the necessary ros to gazebo bridge. I filed the appropriate issues to have gazebo start doing the builds. I guess I will have to learn how to build the packages from source. This was another great ROS2 video.

thanks. im still far from simulating. need to finish that differential equations and physics textbooks lol

Thanks a lot for the videos, they’re amazing! I’d really like to see a ros control tutorial,

Thank you sooooooooo much mate

How can I do this with the new Gazebo (Gazebo Fortress) and NOT Gazebo classic (Gazebo 11) as used here ?

can I follow this tutorial with ROS1 too?

Good job, boy.

Are you planning on making an updated video with the new gazebo in place of gazebo classic?

Thank you so much for the awesome video. I am trying to incorporate robots with .dae mesh links instead of predefined boxes or cylinders. But it's not getting spawned into the Gazebo. It's successfully spawned, but nothing is loaded in the Gazebo. It would be a great help if you could suggest some ideas on it. Thank you.

Can you do a tutorial on gazebo fortress?

Hi, really useful and clear video! I am applying the same methods for my own project. However when I publish to the topic as shown at 16:06 with the joint names and input the simulation doesn't change. I am publishing the joint states and have included the joint_pose_trajectory plugin. For reference I've tried to move the joint with an effort controller and this works, so the problem doesn't lie with the joint its self. Any guidance would be appreciated.

Any chance we could see a ros_control tutorial for ROS2? The Construct has a decent one for old ROS, but trying to understand the ros_control framework, how it may differ in ROS2 vs ROS, and trying to map those ROS1 launch XML's into Python for ROS2 is a struggle.

Hey there, great video. I have seen some tutorials where a sensor broadcaster is configured in the yaml file (Something like imu_broadcaster: type: imu_sensr_broadcaster/IMUSensorBroadcaster) and then it is spawned in a launch file like a joint_state_broadcsater. Is that unnecessary? Can I just put the sensor in gazebo tags in my urdf and the topic will be available to my ROS2 nodes?

Excellent video tutorial. Everything is explained so clearly. Thank you so much! I've been following the step by step process on ROS2 Humble with Gazebo classic. Weirdly, adding damping in the URDF files like you did doesn't seem to invoke any friction in the Gazebo simulation. Not sure if it's a Humble issue or some other one

Thank you for the detailed video. I learnt a lot. A small feed back - can you please highlight the mouse pointer and make it bigger? Right now it is hard to follow your voice and see where you're clicking/pointing.

16:38 mine is bouncing around the place , thats why im here , you say add friction ?

I'm a beginner, and in this video is the gazevo run on pc? Or is it run by Raspberry Pi?

Hi.. I'm working on gazebo ros2, I am unable to save my environment and throughout the video, u are using gazebo so smoothly but I couldn't do it. please help me and I use ros2 humble and gazebo 11 version. pls help

Thanks a lot for the video, but I still have questions after watching it. I tried to repeat the video material, but I was faced with the fact that the created world does not start through the world parameter? As it turned out, it is not declared in the file at all rsp_sim.launch.py ? How then should it work?

Hi! You mention @20:40 that you won't go into the Camera details as there is some camera tutorial I haven't been able to find. Could you maybe link me to that content, I'm really interested.

you saved my life gazebo master

hi how are you getting topics automatically? I am doing everything the same ,the only difference is i am using .sdf file and not xacro(in ros-noetic). during simulation i can see the image of object shown by camera rectangle, but no topic is created in rostopic list. you are writing depth and all depth topic got created, how?

Hey this is a great series and I love your videos! I had a problem immedietely however when trying to launch the seesaw world.I'm running ros2 galactic with gazebo on vmware. i copied your code directly from your blog and although gazebo launched fine there wasn't a seesaw inside of it. Is there a different video I should watch first? Thanks :)

Hello can cutting food task be done in gazebo? And if yes which plugins to be used

Would be cool If gazebo have some sound.

“Chopped!”

I'm trying to implement your solution to better understand ROS2 and Gazebo. But, I'm stuck at " Example - Joint states & control". How do you install the Gazebo plugins? I tried cloning the repository "yossioo/gazebo_ros_joints_publisher" but when I try to build it I get the following error: CMake Error at /home/alemoreno991/anaconda3/envs/ROS2/lib/python3.10/site-packages/cmake/data/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:230 (message): Could NOT find Protobuf (missing: Protobuf_LIBRARIES) (found version "3.12.4") Call Stack (most recent call first): /home/alemoreno991/anaconda3/envs/ROS2/lib/python3.10/site-packages/cmake/data/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:594 (_FPHSA_FAILURE_MESSAGE) /home/alemoreno991/anaconda3/envs/ROS2/lib/python3.10/site-packages/cmake/data/share/cmake-3.22/Modules/FindProtobuf.cmake:650 (FIND_PACKAGE_HANDLE_STANDARD_ARGS) CMakeLists.txt:7 (find_package) Could you help me out?
