## Useful for

- Build the robot from the BOM and guide, printing parts on a 3D printer
- Train a custom walking policy in MuJoCo and deploy it on a Raspberry Pi Zero 2W
- Test sim2real by running a pretrained ONNX policy via v2_rl_walk_mujoco.py

## Why it’s here

- Star-counter measurements on 2026-10-25 (UTC), 11:02–13:08: 4475 → 4477 stars (+2). This is the change over that interval.
- Estimated end-of-day forecast: about +11 stars, using observed gains and the previous day.
- Over the last two days the pace is 2.1× that of the previous week and a half.
- Elevated gains were measured on the last 2 completed UTC days in a row. Continued growth is not guaranteed.
- GitHub Trending Python today: #6, +44 stars.
- About 5 forks a day — people are taking the code.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 567
- Issues and pull requests: 58
- Watchers: 81
- Average over the last week: 24 per day
- Usual pace: 9 per day
- Stars in the last hour (measured): 1

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
