Hello,

I am using the github repository (https://github.com/ongdexter/ar3_core.git) in an attempt to control the AR3 robot using ROS. When I run Moveit! or Gazebo, my controllers spawn correctly and everything works. However, when I plug the robot into my laptop and attempt to run the ar3hardwarebringup.launch file, the console output gets stuck on loading the controllers defined in the controllers.yaml file. The controllers and variables are loaded onto the parameter server.

As described here (https://answers.ros.org/question/284099/controller-spawner-stuck-while-loading/), a multi-threaded spinner is used in the hardware_interface node. I am at a loss in trouble shooting why the controller spawner gets stuck loading the controllers.

Please let me know if any other information is required to help solve this issue.
