Learning Robotics using Python - Second Edition

Message passing interface: This is the core feature of ROS, and it enables interprocess communication. Using this message-passing capability, the ROS program can communicate with its linked systems and exchange data. We will learn more technical terms concerning the exchange of data between ROS programs/nodes in the coming sections and chapters. Hardware abstraction: ROS has a degree of abstraction that enables developers to create robot-agnostic applications. These kinds of application can be used with any robot; the developers need only worry about the underlying robot hardware.
