Name Programing for the Robot Operating System
Description

High complexity of tasks that the modern mobile robots are facing calls for using a programming infrastructure which enables efficient integration of independently developed subsystems into a single system enabling autonomous robot operation. The Robot Operating System (ROS) offers an environment for developing modular control software, a communication infrastructure to connect the software components and an open source library of implemented algorithms. In the last five years ROS has become the standard for robot control in the academic community and its influence is spreading also in the industry. In the scope of this course we shall cover the practical development of software modules in the ROS environment and their integration into a completely functional system for autonomous robot control.
