The root README has the timeline of all generations since 2009. Each generation folder explains its hardware and what is in it. .gitattributes turns off line-ending conversion so all files stay as they were.
The Arduino IDE needs the folder name to match the .ino: HexapodRobot/, Hexapod_NEW/ and Hexapod_Teensy/. References in 2026-current/CLAUDE.md updated.
