Explore the fundamentals of robotics AI model development in this comprehensive 21-minute tutorial that examines the critical decision between building versus buying robotic systems, specifically focusing on the SO-101 robot. Begin with an overview of leader-follower setups and dive deep into the SO-101's specifications, comparing it against alternatives like the SO-100 and Moss v1 models. Learn how robot AI models function at their core and discover the key differences between robotics models and large language models (LLMs). Examine the main categories of robot models including ACT (Action Chunking with Transformers), NVIDIA's GR00T, and pi0 architectures, understanding their unique approaches to robotic control and learning. Analyze the practical considerations of building versus purchasing robotic systems, including cost factors, customization capabilities, and development timelines. Gain insights into 3D printing requirements and printer recommendations for those choosing the build path, with specific guidance on equipment like the Ender 3 V3 SE and Bambu A1 printers. This tutorial serves as the foundation for a multi-part series covering robot model training and fine-tuning techniques.
