What it is:
Open Duck Mini v2 is a miniature replica of Disney’s BDX droid. The biped stands 42 cm tall. The author describes the repository as “a work in progress”; many scripts are undocumented, and the repository will continue to be organized.
Hardware list and approximate cost:
The frame is built mainly from 3D-printed structural parts. A Raspberry Pi Zero 2W runs the trained walking policy onboard. The README does not provide a complete list of servo and electronics models. The full BOM is available through the official Google Sheets link, with a Chinese version in a Feishu document. The official text states that the complete BOM costs under $400.
Build overview:
1. Open the official BOM spreadsheet and purchase all parts
2. 3D-print the structural parts according to print_guide
3. Assemble the robot according to assembly_guide (officially marked as incomplete)
4. Test it directly with either of the two officially released trained ONNX walking policies, or retrain one yourself with MuJoCo Playground
5. Use the Open_Duck_Mini_Runtime repository to deploy the policy to a Raspberry Pi Zero 2W for sim2real execution
6. To train your own policy, refer to sim2real.md
Getting-started advice:
The official assembly guide is marked as incomplete. If you get stuck, ask directly in the Discord community instead of struggling with the documentation.Models & stability

Keep exploring

A complete hardware design released by JPL for a six-wheeled Mars rover. Its rocker-bogie suspension and differential pivot keep every wheel in contact with the ground while climbing. A Raspberry Pi serves as the brain, and the full build costs about $1,600.
