This course will teach you all about the Robot Operating System, how to use the ROS2 on a Raspberry Pi 4, and how to write your own ROS programs.
In this course you will learn:
ROS (Robot Operating System) is an open-source, meta-operating system for your robot. It provides the tools and libraries that allow you to quickly create and deploy robotics applications. ROS provides a flexible framework for writing and executing code, as well as a wide variety of libraries and tools for navigation, manipulation, and perception. ROS is used by many leading robotics companies and research institutions worldwide.
ROS can be very intimidating at first, but don’t worry - it’s actually quite manageable once you understand the basics. This course is a great starting point for unpacking and learning how ROS works.
ROS can be installed on Windows, macOS or Linux; however for robotics we often want to install this on a single board computer such as the Raspberry Pi 4. In fact ROS.org supports ROS on Raspberry Pi 4 running the Ubuntu OS, or the standard 64 bit version of the Raspberry Pi OS and running ROS within a Docker container; this is what we will use in this course.
The 8Gb version of the Raspberry Pi 4 is recommended as ROS is quite memory hungry, and the Raspberry Pi cannot use a large swap file as it damages the SD card over time (due to the large number of writes to the flash storage).
