Poppy Humanoid specs

Caveats · stated by the package

• Project is dormant. The main repo was last pushed 2021-12-06 and poppy-docs 2022-12. poppy-project.org, docs.poppy-project.org and the forum failed DNS on 2026-09-25, so every docs link here points at the poppy-docs GitHub source.
• No per-line prices anywhere upstream. The README only says a full build costs $8,000-9,000, about 60% of it for the 25 Dynamixels. The only priced lines are the Generation Robots kit (€7,862.40 incl. VAT without 3D parts, €9,971.52 with them; both 4-6 week lead time) and single MX-28AT (€329.40 incl. VAT).
• BOM sources conflict. The per-section counts in the current guide (bom.md) add up to 13 MX-28 + 5 MX-64 + 2 AX-12 and leave out the arms. The motor config and the archived 1.0 BOM agree on 19 MX-28AT + 4 MX-64AT + 2 AX-12A, which is what this package uses.
• Fastener, horn and cable quantities come from the archived 2015 '1.0 pre-release' BOM (bulk packs). The current guide only gives per-sub-assembly counts and never totals them.
• 12 V supply count conflicts: the archived BOM lists one Robotis PS-10 12 V 5 A, while the current wiring guide and the kit list two. Two are used here.
• Head electronics drifted. The archived BOM describes an Odroid U3 head with a USB OV2643 camera, a 5 V UBEC and an optional Manga Screen. The current guide describes a Raspberry Pi 3 with a fake screen. Generation Robots lists a Pi 3 B+ plus a 3.4-inch DSI display and RPi camera on one kit page and a Pi 4 on the other. The Pi 4 'Poppy Eve' head is documented in a separate repo and not packaged here.
• Speaker and threadlocker vendor links are 2015 Farnell URLs copied from the archived BOM and were not verified. No part number is given for the speakers, the camera or the 5 V Pi supply.
• No grams, print hours or print settings are published. The reference parts are SLS polyamide (the 2015 BOM says 'white polished polyamid'), and FDM suitability isn't documented. The newest STL set is release 1.0.2 (2016). The repo's hardware/ folder only holds SolidWorks files via git-lfs and URDF meshes.
• The archived BOM lists a black 'hide-screen' head part, but the STL zip and current guide use 'screen_support'. The screen_support colour is not stated.
• Written instructions are missing for the double MX-64 sub-assembly and all leg sub-assemblies, which point to YouTube videos. No torque values are given anywhere.
• Licences: hardware CC-BY-SA-4.0 (hardware/LICENSE.md), software GPL-3.0 (software/LICENSE). The name 'Poppy' is a registered trademark, and the README asks forks to keep attribution to the Poppy project and its authors.
• The Dynamixel MX series is Robotis's older Protocol 1.0 line (the X series has largely replaced it). Check that MX-28AT/MX-64AT are still available before planning a build.
