Cookwala / SDK et scénarios / 031
Compare two devices on the same recipe: same plan length, different rungs
Two kitchen robots with the same operations and different sensors both plan lentil soup. The plans have the same eleven steps; the verification column is where they differ.
Lire d'abord: /docs/CORE/ /docs/QUICKSTART/
Étapes
Without thermometers: heating, boiling and hot holding are logged estimates.
dryRunWith thermometers: pan surface, liquid and core temperature verify the same three steps.
dryRunThe difference is four sensors in the capability documents.
getDevicesBoth robots cut the vegetables under their camera; the knife step is identical.
Résultat
You can diff two devices by the rung each step gets, which is a fair way to compare products: not what they accept, but what they verify. Next: scenario 010 does the same with estimates forbidden.
