- YJ30。 Industry and security inspection Police patrolThe first quote is the YJ30's own product description (same page). Translated: (education/research) points to research and development; (patrol/inspection) to inspection; (emergency response/rescue) to defense and emergency response. The other two quotes are from the page's shared section (the same three cards appear on all four YJ30-series product pages): (police patrol) points to security and surveillance. The third card, (power-line inspection), only repeats inspection.Source and note: Intended use, per the manufacturerA yuejialingdong.com/index.php/yuejiasizuxilie/56.html · Retrieved 25 August 2026

Against the field
Each strip holds every robot of this type in the guide that states the figure, one bar per group of values. Further right means a larger figure, not a better robot.
Height
46.2cm18.2inOur conversion from 462 mm. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.
89 quadrupeds state a height
65 state a higher figure, 19 a lower one.
Weight
17.5kg38.6lbOur conversion from 17.5 kg. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.
124 quadrupeds state a weight
85 state a higher figure, 35 a lower one. Log scale: each step along the axis multiplies the value.
Runtime
90–120minNote: load condition not stated
104 quadrupeds state a runtime
YJ30 states a range, not one figure, so it is shown as a band and not ranked against the others.
Indicative price
11,608USD
16 quadrupeds state a public price
7 state a higher figure, 7 a lower one. Log scale: each step along the axis multiplies the value.
Max speed
10.8km/h6.71mphOur conversion from 3 m/s. The manufacturer does not state an imperial figure itself, so the conversion has no source of its own.
113 quadrupeds state a top speed
44 state a higher figure, 35 a lower one. 10 more state exactly the same figure.
Notes
The manufacturer's own table has a typo in this model's dimensions, missing a letter from the unit, on both the Chinese and English pages. Read as millimetres, not metres.
The manufacturer's table merges “climb angle” and “degrees of freedom” under one heading but gives only one value, with a degree sign — so degrees of freedom is left unstated.
The manufacturer's own table gives two runtime figures in the same cell: 1.5-2 hours standard, and 3 hours with an optional second battery. The figure given is the standard one.
The manufacturer's marketing text hints at a laser/vision sensor system, but the specification table has no LiDAR row.
