概況、物料清單與資料
项目概况
Zeroth-01(原名 MicroStompy)是 K-Scale Labs 社区做的入门级人形机器人,官方口号是“BOM 起步价 350 美元”。全身打印件加 16 个总线舵机,配摄像头、麦克风和圆形屏幕,可以跑视觉和语音。
K-Scale Labs 已于 2025 年 11 月停止运营,并宣布把 K-Bot 和 Zeroth Bot 的软硬件全部开源(硬件 CERN-OHL-S-2.0,软件 MIT)。原文档站已下线,资料以 GitHub 仓库为准。

Overview
Zeroth-01 (formerly MicroStompy) is the K-Scale Labs community’s entry-level humanoid — “BOM starts at $350”. Printed parts plus 16 bus servos, with a camera, microphone and round display for vision and voice.
K-Scale Labs ceased operations in November 2025 and open-sourced all K-Bot and Zeroth Bot hardware and software (hardware CERN-OHL-S-2.0, software MIT). The old docs site is offline; GitHub is now the source of truth.
Key specifications
| Servos | 16 × Feetech STS3250 50 kg bus servos (STS3215 is too slow, no longer recommended) |
|---|---|
| Controller | Milk-V Duo S + Waveshare bus-servo adapter |
| Sensors | Adafruit 9-DoF IMU, Milk-V camera, microphone, 3 W speaker, RP2040 round LCD |
| Software | kos-zbot (robot OS), ksim-gym-zbot (RL training) |
Bill of materials
Electronics total ≈ US$347 (servos at historical price; current price varies by seller). Fasteners and prints are unpriced in the official BOM.

3D printing & fabrication
- Official settings (Bambu): 0.16 mm layers, 5 walls, tree supports; filament is not specified — PLA or PETG both work.
- The official print pack has 22 STLs and a Bambu .3mf plate (hands, elbows, shoulders, head, neck, torso, hips, knees, ankles, feet).

License
The zeroth-bot repository currently carries only an MIT license (the README says MIT too). K-Scale’s November 2025 shutdown announcement says hardware is released under CERN-OHL-S-2.0 and software under MIT, but no CERN-OHL-S file has been added to the repository yet — follow the repository files and keep attribution.
