This is a recipe for building intermediate-priced robot dog from scratch with all commercial/3D-printed parts, controlled by Rasp Pi 5 and ROS2 Jazzy. A manually coded walk gait is implemented so far, which can be controlled by a controller to move forward or change directions. It does not yet have an IMU required for RL training; however, I believe it's one of the simplest design out there available for multiple development paths.

Could you build this?
No This is a physical 12-DOF quadruped robot involving hardware design, 3D printing, electronics integration, and ROS2 robotic kinematics/gait control.
What it would actually take: Building this requires mechanical CAD modeling and 3D printing of durable linkages, selecting high-torque servos/actuators and power distribution systems, and wiring them to a Raspberry Pi 5. The software stack runs ROS 2 with custom kinematics nodes (forward and inverse kinematics) along with closed-loop balance and gait control algorithms tuned to physical sensor feedback. Success depends on cross-disciplinary expertise in mechanical engineering, embedded electronics, and robotics control theory.
