I am going to implement behavioral cloning for erle rover. For this, I need to collect front camera data while driving the rover manually using RC. Since I heavily rely on ROS as the middleware, I would like to create a ROS bag that contains sensor data together with my control signals (throttle, steering angle).
Thanks to your example, I know how to control the rover using MAVROS. But how to make the ROS record my RC input values when I use the vanilla remote control? I am not sure these values go through any ROS topics.
