ORION: A DIY 12-DOF QUADRUPED ROBOT DOG

Summary from the TLDR Hardware newsletter

Orion is an open-source, 12-degree-of-freedom quadruped robot designed, fabricated, and programmed from scratch using ROS 2, custom 3D-printed components, and serial bus servos. The repository provides complete mechanical CAD models, kinematic calculations for dynamic walking gaits, and step-by-step firmware integration guides. This project provides engineering teams and builders with an accessible reference architecture for prototyping low-cost legged locomotion platforms.
