Gazebo simulation- Wheels of SUMMIT XL robot not rotating in gazebo

Hi,

I guess you are running the simulation from sources.

Recently we disabled by default the use of the DiffDriveController plugin because we were not getting the desired behaviour, and we set by default use of the ros_planar.

In case you want to run the simulation by enabling the DiffDriveController you can run it with the argument ros_planar_move_plugin:=false.

roslaunch summit_xl_sim_bringup summit_xl_complete.launch ros_planar_move_plugin:=false

Thank you for your reply. We also figured out the same. Thank you once again.

One quick doubt is that where is the ros planar plugin argument is linked to ros planar controller? We are unable to find out that link.

It is linked at URDF model description level as a xacro.
All the summit_xl bases share the summit_xl_base.gazebo.xacro

Then, in the main robot.xacro we have an argument to include it.

And finally, in the gazebo one_robot launch we pass the argument here:

<param name="robot_description" command="$(find xacro)/xacro '$(find summit_xl_description)/robots/$(arg xacro_robot)' prefix:=$(arg prefix) **ros_planar_move_plugin:=$(arg ros_planar_move_plugin)** omni_wheels:=$(arg omni_drive) --inorder"/>

Hope it helps!

Great got it. Thanks for your prompt response.

We are trying to simulate a custom path movement of summit xl in gazebo, and perform them on real-world using the robot. That's why we are using the differential control drive.. is it recommended to proceed with gazebo.? And why desired behavior is not expected with differential drive controller in gazebo? As we didn't find wheel rotation in ros planar, we enabled the differential drive controller plugin. If possible, Can you please explain the reason for not using differential drive controller plugin by default?
