What does this course tell? (Please note that the following overview content is from the original platform) [Updated with ROS Noetic! This course is now valid for ROSKinetic, ROSMelodic, and ROSNoetic]Learning ROS is hard, and you know it. But why should it be that way?There is a lack of structured resources for beginners. You can find some explanations and programming tutorials online about Robot Operating System, but they won’t really tell you which path to follow when you begin, where to go, what to focus on, ...That’s why I’ve created this course, that I wish I had when I begun. So you can learn ROS much faster than I did.The goal of this course is to remove the big learning curve that you face when you start to learn ROS by yourself. I will show you, step by step, what you need to know to get started and master ROS basics.This course is :Structured in a way that is easy to follow for a beginnerGoing through all ROS core concepts that you need, step by stepGoing to the point. No useless and over-complicated stuff that you won’t use anyway.Full of practice and challenges to make you progress fasterNow, why should you choose my course?In the past I have developed a complete ROS software for an entire 6 axis robotic arm. I’m telling you that because by developing this robot, I learned (the hard way) what I really needed to know to build things that actually work. My experience with ROS is not only about university work or a weekend hobby: I actually co-founded a business with a robot powered by ROS. By doing so, I had to focus on going to the point, finding what is useful, and what is not.So today, with the practical vision that I’ve developed, I know exactly what you need to learn at the beginning if you want to get serious about building robotic applications.What is this course about?This course will guide you, step by step, through all the ROS core functionalities. We’ll focus on ROS basics, communication tools, and also on how to build a scalable application with Robot Operating System.For each section, I will explain one concept in a way that is easy to understand, and then you will practice with me by writing, building, and running some code. I will show you what you need to pay attention to, what you need to focus on, and how to avoid common mistakes. And, more importantly, I will give you some activities and challenges to make you practice on the concepts that you’ve just seen.Note that all the code written in this course will be both in Python and C++, so you can decide to learn ROS with those 2 languages, or only one of them.So… Start your learning today and build awesome robotic applications with ROS !After installing ROS on a Ubuntu OS, you will learn the following ROS key concepts :NodesTopicsServicesMsg and Srv definitionsParametersLaunch FilesAnd much more!By mastering those concepts, you will be 100% ready to start any other robotic application and build complete software from scratch using Robot Operating System.You will also learn how to :Debug your programUse command-line tools for each key conceptBuild your applicationCorrectly set up and manage your project structureAnd as I want to make you develop great (not just good, because “good” is not good enough) and scalable robotic applications, I will share with you the best practices that I’ve learned from my own experience.UPDATE:Note: this course targets the first version of ROS, or "ROS1".This is not a ROS2course.- Should you learn ROS1 or ROS2?Well, ROS2 is the future of ROS, that is for sure.But for now, ROS1is much more stable and mature than ROS2. Almost all serious projects and community packages target ROS1, and many of them are lacking in ROS2. You still have a few years before ROS2 will surpass ROS1.Learning ROS1 will allow you to work today on existing projects and get all the available features. Also many companies still work with ROS1, so if you want to get a job soon that's the way to go.Finally, once you have the basics with ROS1 and a few projects under your belt, switching to ROS2 actually won't be that hard.Most of the concepts are identical for the 2 versions.The best option would be to learn ROS1, ANDROS2. So you can work with any existing ROSproject, and also work with the new framework.All in all, don't hesitate too much: the best thing you can do is to start learning ROS today, whether it's ROS1 and ROS2. We considered the value of this course from many aspects, and finally summarized it for you from two aspects: skills and knowledge, and the people who benefit from it: (Please note that our content is optimized through artificial intelligence tools and carefully reviewed by our editorial staff.) What skills and knowledge will you acquire during this course? By taking this course, learners will acquire the following skills and knowledge: 1. Understanding of ROS core concepts: The course covers all the essential concepts of ROS, including nodes, topics, services, message and service definitions, parameters, and launch files. 2. Practical application development: Learners will gain hands-on experience by writing, building, and running code for various ROS functionalities. They will learn how to develop scalable applications using ROS. 3. Debugging skills: The course teaches learners how to debug their programs effectively, ensuring smooth operation and identifying and fixing errors. 4. Command-line tools: Learners will become proficient in using command-line tools for each key concept in ROS, enhancing their efficiency in development. 5. Project structure management: The course provides guidance on setting up and managing project structures correctly, ensuring organized and maintainable codebases. 6. Best practices: The instructor shares best practices learned from their own experience, enabling learners to develop high-quality and scalable robotic applications. It is important to note that this course focuses on ROS1 (Robot Operating System version 1) and does not cover ROS2. However, the instructor suggests that learning ROS1 first is beneficial as it is more stable and mature, with a larger community and available packages. Learners can later transition to ROS2, which shares many concepts with ROS1. Who will benefit from this course? Robotics Enthusiasts: This course is ideal for those passionate about robotics and looking to gain proficiency in ROS for building and controlling robotic systems. Students and Researchers: Students and researchers in the fields of robotics, automation, and artificial intelligence will find this course invaluable for mastering ROS and its core concepts. Software Developers: Software developers aiming to expand their skill set into the domain of robotics and automation can use this course to start their ROS journey. Engineers: Engineers, especially those working in the areas of mechatronics, automation, and control systems, can benefit from the practical knowledge of ROS offered in this course. Entrepreneurs and Business Owners: Individuals interested in robotics and considering business ventures related to robotics, automation, or industrial applications can gain a solid foundation in ROS through this course.
