ARES-6 six-legged rescue robot in Three.js

What it tests: A large spec with an explicit acceptance list: a hierarchical robot rig, tripod gait, arm and claw, sensors, a drone, mission presets, telemetry, and a failure-and-recovery state.

Prompt length: 11,481 characters, roughly 2,870 tokens (estimate). Set a large context in your runner so the prompt and a long answer both fit.

How to grade it

Go through the prompt's own acceptance criteria: robot visible in 3D with six legs; orbit camera; sliders move parts; tripod walk cycle (FL+MR+RL, then FR+ML+RR); visible lidar, thermal and searchlight effects; the claw opens and closes; debris grab demo; the drone launches and returns; mission presets change state; live telemetry; the System Failure Test shows warnings and Auto Stabilize clears them.

Where models usually fail

Legs not built as a joint hierarchy, so knees bend around the wrong pivot; a walk cycle that moves all legs at once; static telemetry; 'demo' buttons that only write log lines.

Running it

Run it one-shot and judge the first answer. Open the result exactly as delivered (double-click for HTML). Give the model a large output budget: long specs get cut off on small context settings.
