Add Review-Single-Checkpoint-Multi-Robot: deploy-side cross-embodiment (one frozen checkpoint, many robots)
New page separating the DEPLOYMENT question (one unchanged checkpoint
controls multiple physical robots at inference) from the training-data cut
in Review-Cross-Embodiment. Organized by three tiers:
- Tier 2 (zero-shot to unseen robot): LAP-3B (actions-as-language, first
substantial zero-shot to unseen), Green-VLA, Gemini Robotics 1.5,
DreamZero/DYNA-2 (WAM), Contact-Anchored Policies, One-Hand.
- Tier 1 (routed seen-robot generalist): RT-X, CrossFormer, RDT-1B,
UniAct, GR00T N1, pi0.5->pi0.7, Motus.
- Tier 3 (contrast, needs per-robot fit): Octo, HPT, X-VLA; plus MergeVLA
(merge specialists into one checkpoint).
Includes a routing-mechanism taxonomy, honest limits (AnyBody, unreplicated
2026 zero-shot claims, 'single checkpoint != nothing per robot'), and a
design guide. Cross-linked from Review-Cross-Embodiment, Reviews, Home.
