Strech robot Gazebo simulation on local computer

Hi all.
I would like to simulate stretch robot on local computer. I followed stretch_ros/stretch_gazebo at master · hello-robot/stretch_ros · GitHub and catkin_make it in my local computer.
However, it turned out the stretch robot steadily turning clockwise in gazebo making it not correct.
Did I miss something?
Thank you.

I haven’t seen the steady clockwise issue you’re describing, but I know the Gazebo Physics engine can be finicky. Recently, I pushed a PR to Stretch ROS that updated the XACROs to make the physics more stable. I’d recommend ensuring you’re using the latest commit. Details in the PR:

Thank you for the reply. however, it is quite different from the issue that I am facing. While looking to the stretch github repo, I found this similar issue Gazebo bug with stretch which unfortunately there is no conclusion on the discussion.
