Deviations and variants in the key figures (4)

Weight

NoteIncludes battery. Without the battery, about 45 kg.

Runtime

NoteAlso >3.5 h with no load (about 35 km). Under the same load and the same battery, A2-W's runtime is under half of A2's (>1.5 h vs >3 h), but its range is longer (about 15 km vs about 12.5 km).

Max speed

NoteOperating range 0-3 m/s; spike up to about 6 m/s. A2-W is faster at its spike than A2 (about 6 vs about 5) but slower in ordinary operation (0-3 vs 0-3.7).

A2-W does not appear in the manufacturer’s English product navigation menu, where A2 is listed under ‘Robot - Industry’ — though the Chinese-language navigation does list A2-W alongside A2 under the same "industry-level" group (the manufacturer’s own Chinese-language label). The category here is therefore the product page’s own sentence, not the navigation’s grouping. The same page also calls the robot an ‘Industrial-grade mobile platform’ — that is a build quality, not a use case, and is not counted.

This category is not our assessment.

Every field in the schema

21 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.
