This is strange. What's the error log? ${PROJECT_NAME} is the name of your project. This variable should be automatically set. share folder is also created automatically .
I'm sorry, I changed a bit the topic (I have modified the original one). It's not the name the problem but I don't have the folders! Thank you for the fast answer@@roboage1027
@@giorgiolongari2806 That's very strange. As I understood, there's no install folder in your workspace's folder? Or there is install folder but there's no share folder in it. It should be like so: your_workspace/install/your_project/share. Does your workspace have such a structure? All this folders are created automatically when creating and building the package.
Unfortunatly i accidently deleted the whole ros2 workspace with all my packages when reinstalling os on my pc. Probably i should have used github. I'm now trying to recreate this project watching my own video. Sorry, that i cann't help you.
thank you so much for your help, for some reason it did not work with my meshes (I mean I cannot see anything even after I modify the package.xml file), but it helped me learn a lot, if in the future you can share your code and meshes for testing, it will help us a lot know what is not working with our own urdf and configs

Hello Roboage, How to give torque to the joints manually? (In gazebo from python script). I have a custom robot model with non-differential model, and have a custom controller for that. That is why, I want to read position, velocity and similar features of the robot legs and give certain torque values to the legs calculated by my controller. For that, I think there is no need to use MoveIt but don't know how to do it. Can you help me? Thanks.
Hi! I guess your custom controller need to inherit from controller interface class and you need to configure it as ROS2 plugin. In such a way you will be able to use your controller as usual ROS2 controller together with Gazebo hardware interface. And your controller will automatically read states from gazebo and write torque commands. And you will be able to send commands to your controller with python just as to usual action ROS2 server.
having difficulties accessing six_dof_arom_on_stand.urdf, please where did you get your urdf and the .dae meshes can you share it; please I need it urgent,... thanks
How do you specify which controllers will be used by Moveit for motion planning? Do you specify these in the Moveit Setup Assistant process or are they being read from the urdf?
Controllers are specified in the configuration file (with .yaml extension). Besides, you should specify path to this file in the urdf file as a parameter for gazebo plugin. I show all these steps in the video when i explain how to configure gazebo with ros 2.
@@junaidamin2412 Yes. Moveit setup assistant generates yet another controllers configuration file. These are controllers of type follow joint trajectory. I don't know why they are needed. I guess for updating visualization in rviz. And that's all. Controllers that you are using to control your robot (in simulation or the real one) are up to you:)
I am getting an error while launching the demo file "default logging verbosity is set to info using load_yaml() directly is deprecated. use xacro.load_yaml() instead." Can you please suggest the possible reason
I downloaded gazebo_ros2_control at the package that was created, and then i launched (ros2 pkg create --build-type gazebo_ros2_ control) l, then nothing happen (error)
I didn't manage to do that either. So I ended up just creating temporal fixed joint between the gripper and the object. And that's it. Then I deleted this fixed joint as soon as the gripper was at drop location.
Hi Roboage. Great video. Loved it! I am also working on ROS2 humble and want to control my arm. I followed your video and was able to spawn my arm in Gazebo but after including gazebo_ros2_controller in URDF file, when I started gazebo simulation, my arm started rotating and flying on its own. Have you ever come across this kind of error? What can be the error here?
Hi! Thank you for your comment! Check inertial properties of your robot's links in URDF file. If they are wrong, simulation will be broken. Also check this link on ROS answers site:answers.ros.org/question/416011/strange-behavior-and-instability-of-six-axis-manipulator-in-ros-2-with-gazeboclassic-when-using-position-control/ Try it, maybe it will help.
@@roboage1027 Hi, The ROS answer was the solution. Thank you. This solved my issue. I was struggling since almost a week. Thank you so much. :) I had to include properties to joints in URDF. (damping and friction).
Hi Roboage, sorry to bother you again. I am getting another problem now. In gazebo my arm can't grasp any object. The object simply slips out of the gripper. Have you come across such behavior?
@@akashparikh6204 Actually it is impossible to grasp object in Gazebo.

I want to get my 6 axis robot up and running for planning and robot vision. Ufactory included a list of demos but I’m not sure how to install that into gazebo and moveit2 and connect to my robot IP address.
There is no short answer. You need to start with updating package.xml and CMakeLists.txt files and finish wth source code of your packages. You would need to remove and update everything, that is not compatible with ROS2.
I mostly work with C++ in ROS2. As i understand, you need to edit setup.py file, so that your config folder was installed in share directory of your package.
Unfortunately, i didn't make github account yet. And recently regretted it, cause accidentally deleted some of the code when reinstalling OS. So i'll definetly make one.
I require some assistance with the modification of urdf of my the robotic arm. I have already created a design and successfully converted it to URDF (Unified Robot Description Format) for ROS2 (Robot Operating System 2). However, I am encountering several issues during the process, and I would greatly appreciate your valuable support in resolving them.
I used solidworks2urdf exporter and i had to modify joints origins and orientations manually because they were somewhat wrong. Also sometimes it is necessary to modify inertial properties of the links. What exact problem you have?
@@roboage1027 I have the error output with me. Is there any way to contact you so that I can share it? It's for my college project, and I have limited time to complete it. I kindly request your assistance.
@@RlxRlx1 I'm not an expert actually. I'm in the process of studying ROS 2 myself and have no experience in connecting real robot to ROS 2. Sorry 😞.
