ROS 2 and Raspberry Pi (+ Arduino) is a course on how to build real robotic systems using Robot Operating System 2 (ROS 2) with affordable hardware like Raspberry Pi and Arduino, published by Udemy Online Academy. This is a hands-on course that teaches learners how to build real robotic systems using Robot Operating System 2 (ROS 2) with affordable hardware like Raspberry Pi and Arduino. The course explains how ROS 2 works, how to install and configure it on Raspberry Pi, and how to connect microcontrollers like Arduino for sensor integration, motor control, and communications. Students learn to create nodes, threads, and services, build robot behaviors, communicate with sensors, and deploy real-time robotic applications.

Key points include learning the basics of ROS 2 architecture, installing ROS 2 on Raspberry Pi, integrating Arduino to control hardware, understanding nodes, threads, and services, working with sensors and actuators, using microcontroller communication protocols, building and testing robotic behaviors, implementing real-time processes, creating complete robotic workflows from software to hardware, and leveraging the combined power of ROS 2, Raspberry Pi, and Arduino to develop practical, low-cost robotic systems. By the end, learners will understand how to design, prototype, and implement practical robots using modern robotics software and low-cost electronics.
