tracked robot Gazebo-ROs
hello, I'm trying to create a simulator in gazebo under ROS, for a robot base. This robot base has tracked wheels. I would like to ask you how to implement them in ros and Gazebo, in particular:
- is there any kind of specific transmission ?
- do I have to build the urdf xacro in a particular way ?
- is there any kind of example (I didn't find it from my own)?
thanks in advance
