One command surface, 20 robots, 100 checked briefs.

Every robot in OmniSim takes plain English. This page is the catalogue of what that surface can be asked to do — and, more to the point, the evidence that it does the right thing when asked, and nothing at all when it should not.

The same job, two architectures

A Husky drives forward two metres, turns ninety degrees, drives back. Three commands, repeated for a day. If a model decides each command that is 26,916 model calls. If a model interprets the instruction once and a deterministic core runs the loop, it is one — for identical robot behaviour.

One instruction plus the deterministic core: $0.003. Fully deterministic: $0.00. The ratio is 26,916× on every row — the same for the cheapest model and the most expensive, because the saving is not a price difference, it is not making 26,915 of the 26,916 calls.

Measured, not projected: 5,592 prompt tokens per command counted with Gemini's own tokenizer on the payload the bridge actually sends, 84 output tokens and 1.88 s latency over live calls, 4.0 s of robot motion per cycle read from the robot's pose. Caching the static prefix at 90% gives $14.31 a day and still leaves a 4,700× gap, because the gap is call count. Reproduce with tests/benchmarks/costbench/.

Why any of this is worth showing

We measured our own natural-language robot interface against real operator utterances and against a set of deliberately awkward ones. The keyword router that shipped before moved the robot on most of the sentences where the correct behaviour was to sit still — questions like how many times have you had to stop? halted it, and how much charge is left? made it spin.

43 adversarial cases, judged by the robot's measured pose rather than by what it said. Raw data and the case list are in the OmniSim repository under tests/benchmarks/commandbench/.

Each step is checked: act means the robot must move, hold means it must not, ask means it must come back with a question instead of guessing. Every brief ends with a safety probe — a question carrying a motion keyword — so all 100 of them assert the one property that matters, not just the happy path.

Run it yourself

git clone https://github.com/omnilink-tech/omnisim
python -m omnisim run-agent --list
python scripts/dev/run_agent_catalogue.py --only husky

No account and no key required. Without an OmniLink key the robots fall back to the offline deterministic parser, which is what every number on this page was measured against.
