Hi Chuong Le! Thanks for watching my video! Did you add the “collision” tag to both objects? Please refer to my other projects in which I am using gazebo for a setup example.
Sorry, I missed your comment. Your sdf file looks fine for me. Can you check the files for this tutorial and compare them with yours? In this tutorial robots are pushing blocks, so collision works fine here. th-cam.com/video/xdch0WDeAxc/w-d-xo.html
Hi M m! Thanks for watching my video! Currently, I am not planning to make a video about joints and links. But I have a lot of examples on my channel, so some of them may be helpful for you. Where exactly are you experiencing a problem?
@@user-lc1kw6me2q So, your robot has 4 wheels. In that case, I recommend you refer to the “husky” repository. Probably your robot is similar to this one. Here is the xacro file in which robot is defined. The wheel part is lines 210~221. github.com/husky/husky/blob/noetic-devel/husky_description/urdf/husky.urdf.xacro
I do not understand, where is that sdf file come from, you only save the file get out of blender, and that is .dae file, my question where is the other two files come from??
Hi fawadkhan8905! Thanks for watching my video! In case of ROS2, usually you create it by converting urdf file. Please see this tutorial for further explanations. th-cam.com/video/XrWrNyrA3vk/w-d-xo.html
Hi Евгений Швайгхофер! Thanks for watching my video! True. I guess that most engineers use CAD to design robots, so probably most of them have a robot model before they go to blender.
what about collision? I added a collision tag around geometry but car pass through it

Here's my sdf file:
true
1 1 1
model://.stl

@ it seems that a LiDAR can’t detect it, but depth camera can. That’s why I think it’s a collision issue
when you go back to ubuntu and load the file, the meshes folder did u create it yourself or is it there by default, i dont seem to find it
Hi ZEESHAN SYED!
Thanks for watching my video!
Yes, you have to create the “meshes” folder by yourself.
Awesome tutorial, thanks a lot for sharing👏👏
Hi krissosful!
Thanks for watching my video!
It is my pleasure if this video has helped you.
Could you also make a video how to do joint links etc?
Thanks

@@robotmania8896 My problem are links. I generated 4 links for each wheel but links vectors seems bigger when vehicle spawn and it rotates or flies.

This video is good, also can make just model 3d in blender if have skill in the blender
