## Summary

A developer built a robot dog from scratch using low-cost gimbal motors, and a video shows the first 2-DOF leg test. Each actuator uses about 14:1 reduction, achieved with a combination of a planetary gearbox and belt reduction to keep the structure compact; the finished robot dog is planned to have 12 DOF and weigh about 3 kg.
