Robot makerShenzhen, ChinaFounded 2022
Builds the rope-driven Astribot S1 robot and the Lumo whole-body VLA models.
Astribot (星尘智能（深圳）人工智能科技股份有限公司) was founded in Shenzhen at the end of 2022 by Lai Jie, previously at Tencent's robotics lab and Baidu. It builds the Astribot S1 robot, the Lumo whole-body VLA model and the DuoCore fast-slow control framework. In June 2026 it reported a Series B, with three rounds totalling more than RMB 1B and a valuation above RMB 10B.

#99 of 104 model companies · score 3.0 / 100 · updated 19 Oct 2026
Each bar shows an input from 0 to 100% before weighting. 0 of 1 listed models have open weights.
The score (0–100) measures public, checkable evidence about a company's robot models. It does not measure private capability. A company that publishes no benchmark results and no weights can still have strong models. Every input is computed from the data on each company page, and every number there links to its source.
| Input | Weight | How it is measured |
|---|---|---|
| Published benchmarks | 35% | For each scored benchmark, the company's best result divided by the best result any company has published, averaged over the benchmarks it reports. No published results scores 0. Results come only from the model's own paper, model card or the official benchmark leaderboard. Scored: LIBERO (4-suite average success, %); SimplerEnv Google Robot, visual matching (%); SimplerEnv Google Robot, variant aggregation (%); SimplerEnv WidowX / Bridge (%); CALVIN ABC→D (average length, 0–5); RoboArena (pairwise rating). |
| Open weights | 20% | Share of the company's listed models whose weights the public can download. |
| Adoption | 20% | GitHub stars on the company's most-starred official model repository, on a log scale relative to the most-starred repository in the list. Hugging Face downloads are shown on company pages but not scored, because gated repositories report zero. |
| Released models | 15% | Number of publicly announced, named models, capped at 5. |
| Disclosed funding | 10% | The sum of the funding rounds listed on the company's profile that were disclosed in USD, on a log scale from $10M to the largest sum in the list. Rounds reported only in other currencies are listed but not converted or counted. This input applies only to private startups and robot makers. For big-tech divisions, research labs and listed companies it is n/a, and its weight is shared across the other inputs in proportion. |
Sources. arXiv papers and official model cards for benchmarks and parameters; official leaderboards (RoboArena); the GitHub and Hugging Face APIs for stars and downloads; company announcements and established press for funding. Missing values are shown as n/a, never estimated.
Updated 19 Oct 2026. Benchmark protocols differ between papers, for example in fine-tuning and number of trials, so small gaps between close scores are not meaningful.
Closed weightsVLA
End-to-end whole-body VLA base model pretrained on large-scale data and fine-tuned on data from Astribot's rope-driven robots; the company lists Lumo 1 and Lumo 2.
No benchmark results on a shared public benchmark have been published for this model.
