ROBOT PROTOTYPE / ISOLATED VERIFIED RUN

A robot snake,
simulated and checked.

Inspect the CAD, replay both seeded MuJoCo scenarios, open the robot descriptions, and audit the fresh-review repairs from an isolated Robot Prototype run.

06 / FRESH VERIFICATIONTHREE MATERIAL DEFECTS CAUGHT AND REPAIRED

01 / PRODUCEDCAD, robot descriptions, control, and seeded simulation passed the lead agent’s first suite.

02 / WITHHELDPossible assigned a fresh verification-only workstream before declaring the outcome complete.

03 / FAILEDThe reviewer found an unlatching safe stop, unsafe stop targets, and a hidden velocity-limit overshoot.

04 / REPAIREDStop behavior was latched and frozen; physics-step measurement exposed and removed the overshoot.

05 / PASSEDThe fresh suite passed 12/12 tests after regeneration. The failure history remains in the completion report.

One rough idea.
A bounded outcome.

The user did not choose CAD, URDF, MuJoCo, control architecture, safety behavior, or tests. Possible elicited the intended behavior and supplied the missing robotics work.

USER$possible
I want to make a robot snake.

POSSIBLEWhat should it be able to do when it is finished?

USERSlither convincingly and navigate around obstacles on its own.

POSSIBLEWhere should it operate, what are we starting from, and should the first proof be physical or digital?

USERA smooth indoor floor. Starting from scratch, only the idea. I want a convincing digital prototype I can inspect and simulate now, with a clear path toward fabricating later.

POSSIBLEI recommend the Robot Prototype Outcome Pack ↗. It coordinates the STEP assembly, URDF/SRDF, MuJoCo simulation, controls, deterministic tests, sim-to-real gaps, and independent verification. Saying yes authorizes repo-local agent skill installation, the shared outcome brief and state files, and local outcome work. External actions still require separate approval. Proceed with this outcome?

USERYes, proceed.
