Builder-Tested Resources
These are tools, guides, and references we actually use and recommend.

A must-have spreadsheet for combat robot builders at any level. Plug in values like blade diameter, motor KV, and voltage to quickly sanity-check spin-up time, tip speed, and system feasibility before you build.

Several pages were refined by the Organized Chaos Robotics team based on real-world experience. Practical, fast, and surprisingly fun to explore.

Repeat Intro to combat robotics & Repeat robotics combat handbook

Written by Peter Garnache, these handbooks distill years of real competition experience into practical guides covering drivetrain design, weapon tradeoffs, and event-tested decision making.
If you’re serious about building competitive robots, these are some of the best references available.
