ROS 2

Robot Operating System 2

Description

ROS stands for Robot Operating System and is an open source project by Open Robotics, formerly known as the Open Source Robotics Foundation.

The Robot Operating System helps to build robot applications by offering software libraries and tools, besides the support of a huge community.

ROS 2 is the next generation of the Robot Operating System with a lot of improvements like using the DDS (Data Distribution Service) standard and the RTPS protocol for its middleware layer.

ROS and ROS 2 have the purpose to help developers to research, test, and produce robotic applications, offering a standard platform.
