Weight

NoteIncludes battery; the battery is separately stated at about 5 kg.

Payload, walking

NoteNo operator. The page adds in prose: it is recommended to keep the weight within 20 kg.

Runtime

CaveatThe manufacturer states two conditions: 5 h standing and 2 h walking, both with no load. The walking figure is used here. No load condition beyond that.

Max speed

NoteThe only Unitree industrial model with no speed figure at all.

IP rating

CaveatIP68 appears ONLY in the heading text (IP68 Waterproof, Industrial Level Heavy Loader), not in the parameter table, which has no IP row at all. B1 is therefore the only Unitree model with a stated IP68, on the weakest source footing.

Every field in the schema

15 of 33 fields stated

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.

IP ratingIP68A

CaveatIP68 appears ONLY in the heading text (IP68 Waterproof, Industrial Level Heavy Loader), not in the parameter table, which has no IP row at all. B1 is therefore the only Unitree model with a stated IP68, on the weakest source footing.

Operating temperature, lownot statedA

NoteThe table's Working Temperature has the sub-row Battery: -5 C - 45 C. That is the BATTERY's range, not the robot's; there is no row for the robot itself. Placed next to B2's -20~55 C, B1 would look worse in cold — and that does not follow from the source.

Operating temperature, highnot statedA

NoteSee temperature_min — only the battery range is stated.
