I sucessfully created and ran a controller_manager file, a tilt.yaml file, a start_tilt_launcher.launch file and a c++ program that allows me to send 4 different servo's commands via ros. The only problem is that if I use 5 servo's, then on the second or third execution of this program, the controller_manager receives an overload error such as this:
