Deviations and variants in the key figures (3)

Payload, walking

NoteThe producer's label: Effective Payload (standard terrain).

Runtime

CaveatThe producer states two ranges – 3.5-5 h / 16-20 km with no load and 2.5-3.5 h / 12-15 km in operation – but does NOT state what load the 2.5-3.5 h applies at. The M20 states its load condition (15 kg); the M20S doesn’t.

Max speed

CaveatThe producer also states 9 m/s as a lab-measured extreme speed. Here the operating speed is used.

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.

The producer writes about "The LYNX M20 series", and the M20S is a variant within that series.

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.

Payload, standing	100kg220lbOur conversion from 100 kg. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.	A CaveatThe producer's label: Maximum Payload Capacity. The page doesn't explicitly say standing. The placement is an interpretation.
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 CaveatThe producer also states 9 m/s as a lab-measured extreme speed. Here the operating speed is used.
Max slope	45°	A CaveatFootnote [2]: Lab-tested slope angle; actual performance varies by surface material.

Stair step, continuous	30cm11.8inOur conversion from 30 cm. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.	A CaveatThe producer's own label: Max. Continuous Stair Height. The ratio between the two step fields is 3.3 times. On the comparable figure, the M20S is on par with Boston Dynamics Spot's 30 cm; had we used the high figure, it would beat everything else in the field.

Notes

Shares a product page with two sibling models as a third tab. Dimensions and weight match the base model, but most other figures are markedly higher — a different robot, not an equipment option.
