My name is mohmmad luqman too 😅

i downloaded docker in my windows as in one of your previous videos can you briefly explain how i can install microROS using VS code in my windows and docker... pls reply ....

Hi, great video, learned lots and used it to rationalize some robot software of my own. Is the moblie app software side of this application available or described somewhere? I am curious how the wifi server is used.

Hi, I don’t know if you can help me but i am trying to install ros2 humble/iron in raspberryPi 5. Seems impossible to install and the only solution I could find is by using Docker. Is there any suggestions or method to solve this problem?

Best ROS and Docker combined tutorial I have seen! I was having a lot of trouble figuring out docker as I am new to it, and needed it urgently and this was the perfect tutorial!

Informative As always!

Great video. Is it possible to add camera data on top of scan data for navigation part to improve navigation accuracy

how can i use ros2 with arduino mega for serial

Hello, could you share the repository for the whole project for ros2

Can this carry any weight

thanks for make a good video, now I'm not lost anymore for my career, I have to growing this skill and will make me have new a career path. Jazakallahu khairan

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?

I want to build one much larger to sweep and clean my floors.

Also adding to the point, Compilation is faster than interpreter.

Sir how you make the structure of the robot? did you order it

Hello , can i ask you some questions

Hi, Muhammad Luqman! To which directory can I clone the file turtlebot3-simulation? To source as a pkg inside the src or as a new Workspace? I tried the first one(as pkg in the src where is the dir ros2_learners), but "colcon build" is not working due to duplicate pkg names (turtlebot3_gazebo). Can you help me?

thank you sir, i love your videos

is it possible to use this camera plugin in drone gazebo simulation?

Hello, I'm facing an issue where I have two Windows host machines (Hosts A and B), both with Docker installed and connected via the same LAN. On Machine A, I have the publisher container, and on Machine B, I have the subscriber container. I've attempted various networking workarounds to establish communication between them, but none have been successful. Could you please assist me in resolving this? Thank you in advance.

I have a question , I want to apply A* algorithm to my robot to navigate autonomously and avoid obstacles , so where should I apply algorithms and test different algorithms which is perfect for me ?

you are the best,

[ros2run]: Segmentation fault . I met this error when I run node ros2_kitti_publisher. The rviz only show image, not point cloud 2 ( point_cloud topic still there ). How to solve this problem ?

As always ! Fantastic video

wonderful video, it will be great if u create new tutorial starting from first level

how to show the line of arrows when it navigates?

Thank you sir for explaining so much in easier way

Thanks for the video! I'm trying to use my own ros2 bag with only lidar data to create a pcl file and to eventually create a map of the explored environment, do you have any tips?

Curious what you think of the new Isaac perceptor?

Hello, thank you for the insightful video. I have a question regarding the execution of Gazebo on Docker. I'm curious about how Gazebo manages to achieve such high FPS (frames per second) when running on Docker. In my experience, I often encounter performance issues when running simulations on Docker, with the simulation speed being noticeably slower compared to running locally. Could you shed some light on how Gazebo is optimized to maintain its performance even within a Docker environment?( nvidia-smi works correctly inside my container)

Sir, i need to compare some path planners in ros2 humble using my custom robot (simulation). How can i do it? can i use turtlebot packages and nav2 stack in doing so? Can you help me please

Hello sir, Taking time in creating this video series is much appreciated, I am a UG student trying to build a fully autonomous bot from scratch, have gone through a quite a bit of material online but none was really helpful(maybe I have a lot to learn yet), I just started with this video series hopefully it would help me, with that if you could help me out with your guidance and other recommendations, it would be of great help. thank you for this amazing content.

I cloned the same branch as you did (humble-devel), but in my local environment, I couldn't find the turtlebot3.repos file. Despite that, I tried copying and running the same command as you did, and unfortunately, I encountered this error [CMake Error at CMakeLists.txt:10 (find_package): By not providing "Findcatkin.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "catkin", but CMake did not find one. Could not find a package configuration file provided by "catkin" with any of the following names: catkinConfig.cmake catkin-config.cmake Add the installation prefix of "catkin" to CMAKE_PREFIX_PATH or set "catkin_DIR" to a directory containing one of the above files. If "catkin" provides a separate development package or SDK, be sure it has been installed.]. Could you please offer some assistance or advice on how to resolve this issue? I'm eager to get started but seem to have hit a roadblock. Any insights you could provide would be greatly appreciated! Thanks in advance for your help.

Assalamuwalikum, Thank you very very much !!! I really really appreciate your work and help. I was stuck for a week with installation, where as your efforts benefits me enormously. I would like to ask you something, "Could you please make a video that blink LED light using ESP32 board and LED light can be controlled with ros2 pub_&_sub?". I wish you best of luck, Allah bless you!!! Thanks, Simon

Your videos are incredible, im learning a lot about ros2 and robotics in general. It is helping me in my personal project. Thanks, from Brazil

i am new to c++ and i want to start learning ros2 but which topics of c++ i need to clear before starting ros2.

Is there any roadmap for learning robotics for beginners!

Hey there, I'succesfully completed your course, in Udemy for self driving vehicles, so far all is good, however Im wondering if there's any chance you could do a video explaining how to transform the data from the camera lane detection algorithm so it can of example be use to compare its steering with odometer or IMU, working on a PID controller and this would be awesome, any thoughts of adding this into your course or as a video, as there is none existing information. And when I compare the yaw of the odom with the angle from the algorithm does not work as they are not into the same reference frame :C Really guys do apretiatate any help from you and you're doing one of the best courses out there for self navigation in ROS

Would you be able to use this map with nav2_bringup navigation? I see that navigation is not launching because there is no map frame, I'm guessing we dont have a map to odom transform. How would you go about this?

Sir, we don't have a configuration file for this??? Like we don't need to add. Py. I have watched your wiki ros documentation in which you added the lidar but you also made a node.py file

Are you working on Robotics Arms with LLM? Do you have insights or leads to it? (Like the beginning intros and insights)

RuntimeError: ImportError: "from catkin_pkg.topological_order import topological_order" failed: cannot import name 'Sequence' from 'collections' (/home/wens/anaconda3/lib/python3.11/collections/__init__.py) Make sure that you have installed "catkin_pkg", it is up to date and on the PYTHONPATH. I am getting this error

I love this tutorial! I have a Portenta H7 that I am working on getting up and going with Micro ROS. Following your tutorial, I receive an interesting failure during debugging, any thoughts our comments would be appreciated! (Windows 10) Configuring portenta_h7_m7 with transport serial Downloading micro-ROS dev dependencies - Downloaded ament_cmake - Downloaded ament_lint - Downloaded ament_package - Downloaded googletest - Downloaded ament_cmake_ros - Downloaded ament_index Building micro-ROS dev dependencies Build dev micro-ROS environment failed: '.' is not recognized as an internal or external command, operable program or batch file.

Will these 2 books will clear me with, Historical perspective and evolution of robotics??

Perfect!! Thank you sir.

hi the first Thank you for video. and I Want see all process. how i can find?
