Hi kaijia6998! Thanks for watching my video! It is my pleasure if this video has helped you!

Hi jongwuk son! Thanks for watching my video! It is my pleasure if this video has helped you.

Hi Maker Tutor! Thanks for watching my video! It is my pleasure if this video has helped you!

Hi YAS! Thanks for pointing out. “l” in the second and third terms should be l2 and l3 respectively. That was a typo.

@@robotmania8896 Thank you,too.

Hi Pratham Gyanani! Thanks for watching my video! The /block_pose topic is defined in the “aruco_pose_estimation.py” script at line 100. You can give manual target points by moving interactive marker inside moveit.

Hi Wk L! Thanks for watching my video! As far as I know, moveit2 doesn’t have a setup assistant right now. So, you have to write all set up files by yourself. The link is in the description, please check it.

Hi ExusBuurn! Thanks for watching my video! You should execute the “controller.py” scripts after you have launched the gazebo world. I created user interface using pyqt5. Pyqt5 is useful for creating user interfaces for desktop applications. But you can not use pyqt5 inside rviz.

Hi Aksh Rajput! Thanks for watching my video! In the moveit.rviz UI, there is a “Joints” tab. You can control each joint by dragging blue bar.

Hi Matteo Cassinelli! Thanks for watching my video! I have never had such a problem. You may try to increase mass and moment of inertia of the robot base. If it will still fall, probably something is wrong with gazebo itself.

Hi Ankit Kumar! Thanks for watching my video! In this tutorial I focused on usage of the “MoveIt” library and theory behind it. Since I am making these tutorials only by myself, it is difficult for me to make a tutorial that will cover the whole process of building a simulation model, because it will take me a great amount of time.

@@robotmania8896 I can completely understand, can I have your email ID for further discussion?

Hi nikhiljohnson6048! Thanks for watching my video! If your robot shakes, please reduce PID gains of the controller.

hi @@robotmania8896 thank you for replying how much do i need to decrease the pid and also if possible can you give me any contact details to contact you as i have to submit this as an assignment for a job opportunity and would really appreciate if you could help me with this

@@robotmania8896 also the whole robot kind of exploded and all the parts flew everywhere is it the problem with urdf?

@@nikhiljohnson6048 I don’t think so. Try to reduce gains to smaller values and see how the robot will behave.

@@robotmania8896 I tried it but it's still shaking I even tried with the default values and it's still the same is there any way I can share the video of what happens.

Hi umar anjum! Thanks for watching my video! If there are no pid gains in your ros_control.yaml file, add them manually. Please refer to the yaml file included in the zip folder which comes with this tutorial.

Hi Joey Chan! Thanks for watching my video! Folder “.gazebo” is a hidden folder. Check the “Show Hidden Files” option in “Files” window. If it does not appear, please execute “$ gazebo” command in the terminal once.

@@robotmania8896 Thanks for ur reply. But one more question why when I rosrun aruco_recognition aruco_pose_estimation.py, there is error like line 104, in callback _colour_img cv_colour_image =bridge.imgmsg_to_cv2(data,"bgr8") and import error :dynamic module does not define module export function.

@@joeychan4728 It seems that this is environment variable issue. I don’t have any specific solution for you, but I have found several posts related to this topic.

@@robotmania8896 Alright thanks!

Hi AI-Mind! Thanks for watching my video! The world file is in the “src/kinova_moveit/worlds/arm_example.world”.

Hi greendesertsnow! Thanks for watching my video! The usage of “Setup Assist” is the same. But the code is different for ROS2.

@@robotmania8896 ok thank you robot mania

Hi vickylogesh1576” Thanks for watching my video! No, it will not run with ROS2. This project is created for ROS Noetic.

@@robotmania8896 ok brother thanks

@@robotmania8896 I tried in ros 2 but it's not worked while I type 6 dof robot in terminal it shows no file or directory

@@vickylogesh1576 As I explained above, this project will not run with ROS2. Please run it with ROS Noetic.

Hi Nitin Shhinde! Thanks for watching my video! Are there any other errors in your terminals or it’s the marker that is just not detected?

@@robotmania8896 Thank you for reply. That's the only error in the terminal.

@@nitinshinde9044 I have never encountered such an error before with this tutorial. I am not sure whether it is a problem of the tutorial or marker detection library. One way to find out is to try detecting the same marker with a simpler program using the same library.

What was the solution Nitin?

@@robotmania8896 hi sir I too got the same error as no marker detected when I executed the command is there any way to rectify it
