Hello, I've been trying to use hector_quadrotor_controller but I'm not sure what I'm missing, my setup is the following:

I'm using hector_quadrotor_teleop to capture controls from a joypad and trying to send those /cmd_vel messages to quadrotor but when I launch hector_quadrotor_controller it asks me for controller_manager/load_controller. Not sure what I'm supposed to implement here, can someone give me some tips?

My goal is to get those /cmd_vel messages 'transformed' into a motor pwm signal.

I'm running an Ubuntu 14.04.02, so ROS-Indigo. Sorry if there are any information missing, this is my first question, just say the word I will fix it.

Edit1:I keep reading about how to use this package for simulation, mostly oriented at Gazebo, am I missing something? I would think that it generates voltage signals to the motor that can be used in a real quadrotor.

I had the same problem. Two things to watch ou are 1. the namespace (note the ns=...), and 2. remapping the topic (note the <remap ....).

<!-- load the controllers -->
            ns="$(arg robot_name)$(arg model)"
            args="$(arg controllers_to_start)"
               to="/$(arg robot_name)$(arg model)/description"
