## Health v2 (maintenance only)
Score: 59/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 100, release rhythm 35, longevity 10
- inputs: {"age_days": 147, "days_push": 2, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, young
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Asimov 1 is an open-source 1.2 m, 35 kg humanoid robot with 25 actuated degrees of freedom, released under CERN-OHL-S for hardware and GPL-2.0 for software. The repository provides mechanical CAD, electrical CAD, simulation models, a bill of materials, and onboard software so builders can fabricate, assemble, simulate, and customize the robot themselves.

## Use cases
- build my own humanoid robot from open-source plans
- self-source and fabricate a bipedal robot from a BOM
- simulate a humanoid robot before building hardware
- research platform for full-body robotic control
- customize an open humanoid robot for experiments
- learn how humanoid robot motion control works

## When to choose
- you want a fully open-source humanoid with complete CAD, electrical, and software design files
- you need a research or education platform for bipedal robotics
- you want to modify or extend a serviceable, modular robot design

## When to avoid
- you need a ready-made, fully supported commercial robot with polished software out of the box
- you lack fabrication resources - parts require CNC machining and MJF printing, or a $20,000 DIY kit
- you need advanced perception like lidar or 360 cameras, which are not included

## Facets
- artifact type: application
- maturity: active
- function: robotics, simulation, embedded, sdk
- domain: robotics, hardware, simulation, developer-tools
- platform: python, embedded, cross-platform
- tags: humanoid-robot, open-hardware, cad, bom, diy-kit, bipedal, motion-control, raspberry-pi, can-bus, robot-design, linux
