Thank you for the informative instructional video. The advantage of using the fusion2urdf package is that it facilitates the export of the URDF file, which contains all the necessary files for ROS2. However, I have a question: if we need to adjust the joints and coordinates of the robot, can we directly edit the URDF file without making changes in Fusion, or is it necessary to modify any related files?
Hi, You can edit for sure the URDF file, no problems on that. ACtually you can create a URDF form scratch and we have been doing it for years. The reason why we would want to use Fusion or OnShape for this is because it allows us to create more intriquet designs, like robot hands, humanois and very complex robots much faster than manually editing the XACRO file.
Wow this makes it easier to build a URDF rather than writing or modifying an existing one. I prefer to use Onshape for CAD- can this be done with Onshape?
Lovely explanation. Would it be possible to follow the same process to model basic wheeled robots? Also, is there a course on robot manipulation where I could see how to give commands to this model?
Answering the firts question: Of course, this method is for any robot, the only difference is that the joints in the wheeled robot will be continuous. As for the second question, there are several courses in TheConstruct that teach you how to send commands to the models. If you are interested in more basic commands, the URDFs for ROS2 course app.theconstructsim.com/courses/83 is perfect for that. If you are interested in more complex commands like robot arm moveit systems the course eon ROS2 manipulation will do the trick app.theconstructsim.com/courses/167
Very detailed tutorial for converting to URDF. I just have a question that when we import from Fusion 360 to URDF, is there a possible way to assign the urdf model physical properties(mass/weight, inertia,etc) that can be further used in realtime applied load analysis or to study more detailed dynamics of the model in simulation?
Thank you for this well-detailed tutorial! Definitely learned a lot. Just out of curiosity, are there any available plug-ins that would allow for a more efficient way of deploying our robotic models from Fusion360 into ROS especially should we need to modify the model later on for adjustment etc? Thank you!
Thanks for this tutorial ! Once we have followed the procedure described in the video, how do we simulate the dynamic response of the joints (eg: PID gains for each motor joints) ? In the rosject workspace, I looked at the contents of the armbot_fussion package but I couldn't find where this was done. If we just publish on the joints, we'll have a perfect answer to the instruction in the simualtion ?
Thank you for the very instructive information. Through this method, would it be possible to generate URDF representations of parallel manipulators? For example, if I want to describe a Stewart platform, one child has more than one parent. How will it be the xacro in this case?
That is not possible because URDF doesn't allow more than one parent in the URDF structure. If case you need parallel structures or closed loops, you can use SDF format which is accepted by Gazebo. However, I don't know if there exists a plugin for that in Fusion360. Also, take into account that, even if Gazebo can show SDF based robots, Rviz can't
If you are reffering to this project: github.com/dfki-ric/phobos, having used it some time ago, the Fusion route is simpler, more user friendly and less prone to issues specially if you are a mechanical engineer and you are used to CAD software. But at the end of the day all systems have their issues. Even if you create the URDFs manually directly in the editor has its issues.
Thanks for your very interesting video about creating URDF with Fusion. Could you use English software for your future tutorials? It would be easier to follow.
Thank you for the excellent tutorial! I have a question: If each link of my robot consist of multiple solids, is there any additional step or adjustment I need to make?
I mean, in a robot usually each link is an assembly, but in the example each link was only a solid. Does this difference impact the process of generating the components before defining joints?
Thanks for your great tutorial. In real world, the robot's structure is much more complicated than in the simulations similar to your video, for example, motors, electrical circuits, wires. How can we model these things in URDF?
They get modeled the same way. In URDF they will be shown as parts in the model and their pysical properties can affect the physics of the Gazebo model
Hi, well the basics is that you have to create it with the command like this: ros2 pkg create --build-type ament_cmake urdfbot_description --dependencies urdf xacro After that the procedure is the same, just that the folders have to be added in the CMakelists.txt. In the course on URDF for ROS2 we explain it in detail and with examples an exercises so that you can understand it perfectly ;) app.theconstructsim.com/courses/83
i followed all the procedure but when i run my URDF_exporter, no error appears but at the same time i get no dialog box for exporting urdf files. and i am stuck badly at this
@@glitchbug3728 i didn't find a solution for this plug-in. But, meanwhile one of my colleague has suggested me to use an add-in ACDC4 which is available online and can be installed for fusion 360. That does export urdf and meshes. I haven't tried it myself but he did that and sent me the exported urdf and meshes files. So i guess that seems to work.

@@TheConstruct Thank you so much for your reply. I totally agree about that
great, that works wonderfully. let's go to part 2...

Great tutorial, I had some problems with exporting solidworks models to ROS, but with fusion is easier for me
Wow this makes it easier to build a URDF rather than writing or modifying an existing one. I prefer to use Onshape for CAD- can this be done with Onshape?
You can do it in OnShape, we did a video on it: th-cam.com/video/TJeCpGnX508/w-d-xo.htmlsi=NsPGv3Av2LcbQCr9
