I have a Gazebo simulation running with a spawned robot. I also have initialized two trajectory-based controllers using JointEffortInterface for Gazebo-ROS plugin -
gripper_controller. I am using MoveIt Group Commander for these two controllers.
I suspect these controllers are shut down at some point in time of the simulation and throw the following error when trying to read
[ERROR]: Didn't receive robot state (joint angles) with recent timestamp within 1 seconds. Check clock synchronization if your are running ROS across multiple machines!
Is there a way I can check if these controllers are enabled and running at any time during the simulation?
