hi , I am working on multi turtlebot3 robot and everything works fine, gazebo, and rviz2 everything is fine. But I want a slam thing like in rviz2 full map should not appear only the portion where robot is standing should appear. I am trying to work on cartographer (like adding a node) but its not working. any advice you can give and provide I shall be very grateful

awesome brother helped me a lot

It is also possible to get orientation with encoders or are you fusing the imu orientation with encoder orientation to get better results with kalman? I like your videos!

Which language should I use to design the AI for my robots (Python or C++)?

Is it possible to just use imu and camera for mapping?

im getting this error : non-network local connections being added to access control list root@docker-desktop:/# source /opt/ros/foxy/setup.bash root@docker-desktop:/# ros2 run turtlesim turtlesim_node qt.qpa.xcb: could not connect to display :0 qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Hi sir, I saw there is a kitti2bag tool as well. Based on your video, so the raw data do not need to be convert to bag before using it in ROS2?

Amazing Video, I learned lot, Can you make it in python?

Thank you very much by that, there are a bunch of valuable information and they are shown in a detailed way!

Hlo bro i am developing a custom object detection robotic arm i just created the URDF file of it and it's working good in rviz please say the process of steps to be followed so that the arm goes near the balls in space and sucks them inside

Could you make a video on interfacing hardware with ros. Something I need urgently

Is it possible that I can install ROS 2 on Ubuntu Desktop or on Raspberrypi OS?

Hi, great tutorial! I followed the steps you provided and managed to get the turtlesim working on my windows host machine. Whenever I try to launch gazebo or rviz however, they crash with the following error: [GUI] [Err] [Ogre2RenderEngine.cc:989] Unable to create the rendering window: OGRE EXCEPTION(3:RenderingAPIException): currentGLContext was specified with no current GL context in GLXWindow::create at /build/ogre-next-UFfg83/ogre-next-2.2.5+dfsg3/RenderSystems/GL3Plus/src/windowing/GLX/OgreGLXWindow.cpp (line 163) I have XLaunch running and I have used the environment DISPLAY=variable host.docker.internal:0.0 however it still doesn't work :(

thanks a lot :)

God Bless you, this is exactly what I needed a few moments ago

This is really awesome and exactly what I was looking for (and much more). Thank you for saving me plenty of time, I can not imagine how I would find all these information!

I’ve been using ROS for years. This is a great video. Looking forward to new content from you!

It is very good explanation and demonstration. Thanks.

Have you created any playlist for SLAM for ros Neotic??

I think you need jpeg compression on esp32

is it possible to have nav 2 on a raspberry pi, it seems gazebo has updated their dependencies which is terrible.

Thanks a lot!!! Great presentation.

Was a tutorial on depth camera made already? From what I understand we can simply just change the camera type = "depth" to make the camera able to view the topic /points ? My issue with this is that there is some kind of transform that it is empty

Dear Luqman, Assalamuwalikum !!! 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

Hello, I'm student of Yonsei University. I've VLP-16 LiDAR and new at ROS2. Our team is currently using ERP42, which is autonomous driving developer kit. We're planning to create node that producing real-time Point Cloud Clustering algorithm, and take your course. How can we process the real time data that produced by VLP-16(may pcd file)? In the lecture, it seems that processing is only done with the pre-given KITTI data set, but I am curious if you also tell me how to process it when there is a real LiDAR.

Hi, thanks for the explanation, as I saw the part about the GPU utilization, could you please guide me on how to visualize the Gazebo or Rviz from a docker container using GPU but not CPU?

i can not run the file roslaunch turtlebot3_gazebo turtlebot3_empty_world . launch . Can you help me?
