After downloading and installing all the dependencies for the simulator, I get the following error message when starting the sim.

I believe it is responsible for the erratic behavior I'm seeing when trying to control the summit_xl with a gamepad. Thank you.

If it matters, I am using ROS Melodic on Ubuntu 18.04.

For what it's worth, I'm also experiencing the same problem using ROS Kinetic on Ubuntu 16.04.

We are using a plugin for the movement of the robot that doesn't needs a pid, so the missing pid gazebo error should be a warning (because it is not necessary in our simulation).

@ShiJbey which problem are you experiencing with the gamepad? I tested the simulation and it is working fine for me with a PS4 controller. Make sure that RViz is not publishing 0 to any cmd_vel topic through pad_teleop plugin while you are using your controller.

That makes sense. Thanks for the quick response! :+1:
