Hi All  
I am working with ROS 2 Humble and Gazebo Classic Version 11 (I prefer classic to Ignition) and am designing a tracked robot with flippers. Currently, I’m using the libSimpleTrackedVehiclePlugin to control the robot (although this will need changing to work with ROS topics). For the flippers, I thought I could use a joint position controller to rotate the flippers to a chosen position. This has resulted in erratic behaviour causing the robot to explode when I input a position. Does anyone know why this might be? Should I be using two separate controllers or should I be writing my own?
