Deviations and variants in the key figures (3)

Payload, walking

NoteThe producer's label is Payload Capacity.

Runtime

NoteThe producer also states 3 h / 15 km with no load. Here the figure with a load condition is used (12 km).

Max speed

CaveatTHREE figures for the same property on the same page: Lab-Tested Max. Speed 5 m/s, Operating Max. Speed 2 m/s, and footnote [1] Lab-tested extreme speed; safety-limited to 3m/s in user mode. Here the operating speed is used – the only one the user actually gets.

Intended use, per the manufacturer

The manufacturer’s words

The LYNX M20 series represents the world’s first wheeled-legged robot built specifically for challenging terrains and hazardous environments during industrial operation. Featuring lightweight design with extreme-environment endurance, it conquers rugged mountain trails, muddy wetlands and debris-strewn ruins—pioneering embodied intelligence in power inspection, emergency response, logistics, and scientific exploration.

FIVE categories in one sentence. It’s the producer’s own list, and the five carry no ranking between them (L27): the robot belongs to all five, not just the first.

This category is not our assessment.

Every field in the schema

20 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.

Payload, walking	15kg33.1lbOur conversion from 15 kg. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.	A NoteThe producer's label is Payload Capacity.
Payload, standing	50kg110lbOur conversion from 50 kg. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.	A CaveatThe producer's label is Max. Load Capacity. The page does NOT say it is standing load. The placement here is an interpretation, chosen because the field structurally plays the same role as Unitree's standing load.
Max speed	7.2km/h4.47mphOur conversion from 7.2 km/h. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.	A CaveatTHREE figures for the same property on the same page: Lab-Tested Max. Speed 5 m/s, Operating Max. Speed 2 m/s, and footnote [1] Lab-tested extreme speed; safety-limited to 3m/s in user mode. Here the operating speed is used – the only one the user actually gets.
Max slope	45°	A CaveatThe producer's footnote [2]: Lab-tested slope angle; actual performance varies by surface material.
Single obstacle	80cm31.5inOur conversion from 80 cm. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.	A NoteThe producer's own label: Max. Single-Step Height.
Stair step, continuous	25cm9.84inOur conversion from 25 cm. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.	A NoteThe producer's own label: Max. Continuous Stair Height. Comparisons should use this figure, not the 80 cm one.

Onboard compute	2x eight-core 64-bit (16 GB + 128 GB)	A NoteThe only specification difference from the M20 Pro, which has three of the same unit.

Autonomy level	not stated	A NoteThe page lists Omnidirectional obstacle avoidance and Point cloud surround view as the only two autonomy entries, but BOTH carry footnote [3][4]: Feature enabled via future OTA update. They don't exist today. An entry that reads the feature list without the footnote attributes the M20 an autonomy the producer itself says it doesn't have yet. The M20S has the same entries WITHOUT the footnote.
