Take your robotics skills to the next level with this guide to mastering LEGO MINDSTORMS Robot Inventor and LEGO SPIKE Prime. You've learned the basics of LEGO robotics with your Robot Inventor or SPIKE Prime kit, and now you're ready for more. This full-color, illustrated guidebook to programming your robotic creations teaches you everything you need to know to level up your engineering skills, using examples relevant to both sets. In no time, you'll be coding movements for autonomous robot vehicles, building interactive games, making LEGO musical instruments, and more. Rather than feature step-by-step instructions for building a handful of models, you'll find essential information and expert tips and tricks for designing, building, and programming your own robotic creations. The book teaches the fundamentals of writing text-based code for your robots using the popular Python programming language; shows how to harness gears, linkages, and other mechanisms to create all kinds of motion; and explores sophisticated programming techniques for popular applications such as line following and obstacle avoidance, using both Python and Scratch-based Word Blocks. As you learn, loads of challenges and open-ended projects will inspire you to try out ideas.
