Building your first robot is now more accessible than ever with tools like ROS2 and affordable hardware like the Raspberry Pi. ROS2 allows you to create modular and scalable robotic applications by using independent nodes that communicate with each other. By following a step-by-step process, starting from setting up the hardware to writing your first ROS2 nodes, you can gradually build and enhance your robot’s capabilities with features like autonomous movement and visual feedback. Courses like those offered by Robotisim provide expert guidance and practical exercises to help you gain confidence in using ROS2 and deploying code to your Raspberry Pi-powered robot.
