Summary

  • Add Dobot CR3 (cra-001) Tier 1 pick-and-stack bridge (laok.cra-001)
  • 6-DOF industrial arm with closed-form IK, real MuJoCo physics
  • Pick-and-stack: cube -> target, settle only on success
  • MuJoCo + PyBullet dual-engine simulation (sim-to-sim)
  • Real x402 payment flow via Go Tunnel (fail-closed gate)
  • Complete test suite: success / unreachable / collision / timeout scenarios

Validation

  • MuJoCo: cube placement verified in pick-and-stack scenario
  • Sim-to-sim: MuJoCo vs PyBullet contract + verdict agreement
  • local Python suite: 91 passed, 16 skipped (pybullet/zenoh need CI)
  • registry profile contract: passed
  • x402 evidence: real Base Sepolia USDC transfer, verify_settlement 1/1

Scope and evidence

Simulator-only Tier 1: the official CR3 is a 6-DOF collaborative arm;
this profile uses a faithful simplified kinematic model for the
pick-and-stack trajectory with real physics failure modes.

Trusted Base Sepolia settlement evidence and the paired paid-action
recording are produced by the configured live workflow.
