Carlos Gonzalez, a quadcopter enthusiast, released a series of blog posts that introduce the fundamentals of drone modeling, state estimation, motion planning, and control. The posts are intended as a concise, accessible overview for newcomers, not as an authoritative academic treatment. Each post includes references to scholarly sources, and some sections are marked as work in progress. Gonzalez explained that he initially attempted to write a longer paper but found it more digestible to break the material into shorter installments, allowing a more casual tone while still providing an intuitive feel for the subject. The guide aims to help beginners understand how quadcopters can achieve autonomy and remains an ongoing resource with future sections expected to be completed.
