We have found free3d and cgtrader web pages that allow free download of 3D models.
After this, the example model is loaded in Gazebo by accessing Model Editor option. It allows different file formats such as .dae, .mtl, etc.
The first image is a model loaded from the external page, while the second one has been loaded from the Gazebo repository.
For the development of the project it is necessary:
- Install ROS 2 Humble, use official installation guide
