Deviations and variants in the key figures (5)

Weight

NoteIn the 'basic parameters' table.

Payload, walking

CaveatThe manufacturer states only the payload figure, without a walking/standing distinction (see the top note). A cautious estimate, not a reading.

Runtime

CaveatIn the base value. The same cell separately mentions '3.5~4h (Dual Battery)' - an extra accessory-dependent configuration, not used as the main value. No load condition (kg) disclosed.

Max speed

NoteMaximum speed - higher than the walking YJ30's 3m/s, as expected for a wheeled variant.

The first quote is the YJ30 W's own product description (same page). Our own translation: (multispectral fire detection/warning) -> defense and emergency response; (autonomous mobile inspection/patrol) -> inspection; -> industry; -> research and development. (warehousing/logistics) is NOT included as a logistics category here, since it appears only in a list of possible deployment environments, not as a standalone application category alongside the others - a more cautious reading than the broadest possible one. The last two quotes are from the page's shared section: -> security and surveillance.

This category is not our assessment.

Every field in the schema

13 of 33 fields stated Imperial unitsMetric units

Imperial figures are our own conversion unless the manufacturer states an imperial figure itself. The source letter always belongs to the metric figure — a conversion has no source of its own.

The letter points to the source at the foot of the page. Fields without a figure are dashed: the manufacturer does not state them — that is not the same as zero, and not the same as no.
