Show HN: Cubic Doggo 07B Wouf: A low-cost open-source quadruped with ST3215

A developer released Cubic Doggo 07B Wouf, an open-source 12-DOF untethered quadruped robot built from off-the-shelf components and 3D-printed parts and controlled via ROS2 Jazzy on a Raspberry Pi. The robot uses 12 ST-3215-C018 smart servos, walks forward with a 1 kg payload, runs on batteries, and requires only 2 soldering points because it has no custom PCB; FreeCAD models are available for editing and M3 screws and locknuts secure the PLA+ structures. The project is positioned as a low-cost development platform for stacking new components, with smart servos cited as required for closed-loop reinforcement learning capability.

Cubic Doggo 07B Wouf is a ROS2-controlled 12-DOF untethered quadruped, built with ST3215 smart servos fully with off-the-shelf components and 3D-printed parts Featuring: 12 ST-3215-C018 servos, usually on a bundled sale because of SO-ARM101 Walking forward with a payload of 1 kg Smart servos as required for closed-loop reinforcement learning capability FreeCAD models fully available for editing M3 screws and locknuts are used extensively instead of glue or heat set inserts to strengthen and secure the PLA+ printed structures. Design iterates on strengthening whichever part breaks first. Check JLCPCB for stronger components No custom PCB because I am terrible at it , only 2 required soldering points Runs on a Raspberry Pi with ROS2 Jazzy installed. Joystick control ready Walks on batteries Aesthetics of an exposed electronic box, but great as a development platform for stacking new components on top Comments URL: https://news.ycombinator.com/item?id=50298302 https://news.ycombinator.com/item?id=50298302 Points: 2 Comments: 0
