What is the difference between URDF and SDF?

My understanding can be boiled down to this: URDF specifies a robot, but SDF also specifies a world for the robot to live in, which is a much larger set of things. Based on this premise, SDF is designed to represent a superset of everything that can be represented in URDF.

How do I launch URDF?

Create a package urdf file under the my_robot_urdf/urdf folder. This file defines the physical parameters of our robot and the type of controller that we want to use. We’ll create a launch file to launch this description. We name it spawn_urdf.

How do I import a gazebo model into SolidWorks?

To actually be able to import your model into Gazebo, you have to add a directory, where the directory with model is placed, to the GAZEBO_MODEL_PATH environment variable. Best place to do it is in your . profile or . bashrc / .

How do you visualize URDF in RVIZ?

My approach so far:

Create a new catkin package named “myrobot_description” with dependencies on the urdf package.
Create a folder urdf in the folder myrobot_description/urdf.
Create a valid URDF-File (as far as check_urdf is concerned)
Build the package with catkin_make install.
