*low level* messages in ROS (Indigo)
Hello everyone,
I'm beginner in ROS and I have a question about the messages in ROS. Are there low level messages in ROS? For example, if i want to move the robot to location (x,y), I need to send a MoveBaseGoal message. I want to know if there is a way to see messages that directly go to motor (if they exist)?
Thanks.
