What you are seeing
Scene
An articulated arm / chain style setup showing constrained motion and linked-body behavior.
Why it matters
Show articulation, chained constraints, and robotic-style motion in a buyer-friendly scene.
Pass condition
The articulated chain should remain coherent, with readable constrained motion instead of unstable collapse.
Proof views
Use Public proof for the clean buyer-facing read, Event focus for adaptive slowdowns around the key moment, and Debug proof for contact cues, overlays, frame numbers, and proof-lane instrumentation.

Systems exercised
- articulation
- constraint chains
- joint stability
- IK-adjacent behavior
Known limitations
- This is a showcase scene, not a full robotics SDK claim.
Recommended context
Use when a buyer wants proof that UPE can support mechanical chains, arms, or constrained rigs.
Determinism status
- same build: scene-capable
- cross-run: validate within deterministic config
- cross-platform: not broadly claimed
- snapshot / restore: supported by broader toolchain
