LiDAR guide
LiDAR maps without an RTK antenna. Mova LiDAX, some Mammotion Yuka and Ecovacs Goat. Check the term on the product page.
LiDAR stands for Light Detection and Ranging. A sensor emits a laser beam, measures return time and derives a distance. By scanning, the robot builds a map of the garden, which is what lets it run without a boundary cable.
Why LiDAR matters
LiDAR removes the need for a reference antenna: unlike RTK it does not depend on satellite reception, so it works under tree cover where RTK degrades.
LiDAR limits
Positioning depends on visible features. On a perfectly uniform open lawn it can struggle. The sensor often sits high, and its field of view can be blocked by tall vegetation.
FAQ
Does LiDAR need a cable?
No. Neither a boundary wire nor an RTK antenna.
LiDAR or RTK?
LiDAR avoids the antenna and works under trees. RTK covers large open areas.
Does LiDAR work at night?
Yes, a laser sensor does not rely on visible light.
Is it accurate on an empty lawn?
Without features, positioning can be harder; camera fusion helps.
Are all LiDAR equal?
No. The term covers 2D and 3D sensors and different fusion setups.
