Performance benchmark
Computed 0-10 capability scores appear only when the required source-backed inputs are verified.
Scoring methodology
Partial evidence confidenceComputed capability scores use a normalized 0-10 scale from official, verified catalog inputs. Missing required inputs are shown as Not enough verified data instead of a numeric score.
Not enough verified data
0 to 3.5 m/s maps to 0-10
Computed from official degree-of-freedom coverage as a proxy for motion envelope.
10 to 50 degrees of freedom maps to 2-10
Not enough verified data
0 to 50 kg payload maps to 0-10
Not enough verified data
Source-backed autonomy, SDK, simulation, or compute evidence maps to 5.5-7.5
Computed from official degrees of freedom, with a small boost when official dexterity-related evidence is present.
5 to 50 degrees of freedom maps to 1-10, with a sensor/end-effector evidence boost
