Zowi is the official open-source biped from bq (sponsored until 2016) — a compact 4-servo educational walking robot, descended from the Otto/BoB Thingiverse lineage (original concept by k120189, Thingiverse 43708). Designed entirely in FreeCAD so every part is editable and remixable. Licensed CC-BY-SA 4.0. Source: https://github.com/JavierIH/zowi
Hardware:
- 4 Futaba 3003 (or compatible) servos
- BQ ZUM BT328 or Arduino-compatible board
- 4xAAA battery holder
- ~38 M3 bolts and 22 M3 nuts
The repository ships the canonical body/chassis/leg/foot STLs plus a deep mods folder with remix variants: Forge, IronZowi, JIM, Kobuki, MicroRaider, Scopum, Zowarrior, Zowimanoid, Zowiquilator. Also includes Arduino code, schematics, and Spanish-language docs.
