2020-12-14 13:48:51 -0500 marked best answer controller_manager and controller library on different machines

I have a 2-machine ROS setup.

M1 is connected to the robot, and runs the node that starts controller_manager (franka_control_node from franka_control).

I developed a new controller on M2. For example, something copied from franka_example_controllers.

Is it possible that the controller_manager running on M1 can run the controller from M2?

Currently I get the error Failed to load <controller_name>. Running rosservice call /controller_manager/list_controller_types does not show the new controller.

Everything works if I move the controller code to M1 and build it there.
