The Tri-Fusion positioning system in Mammotion's Luba Mini Vision AWD robot lawn mower promises location accuracy to within plus or minus 1cm.

Mammotion announced a new robot mower navigation platform ahead of the IFA trade show in Berlin on Thursday: Its Tri-Fusion Positioning System combines LiDAR, Real-Time Kinematic (RTK), and vision capabilities into a single system.
Combining two of these technologies is not uncommon. Older mowers have used a combination of LiDAR and RTK for much of the past half-decade, while combining one or the other with vision navigation has gained favor more recently. And while some robot mowers have all three technologies onboard, they aren’t necessarily connected for navigation, and serve other mower operation purposes.
Mammotion says Tri-Fusion is the culmination of nine years of development effort, and that it be made available as firmware updates for its recently released Luba Mini AWD LiDAR and the Yuka Mini Vision robot lawn mowers as well as several yet-to-be-announced models.

“Whether you have a compact city garden or a sprawling countryside lawn, it delivers high-accuracy mowing in any environment, sunlit or shaded, open or obstructed, flat or hilly,” said Mammotion CEO Jayden Wei
No positioning technology is perfect
Each navigation technology has its own strengths and weaknesses. Vision has given mowers the capability to accurately detect and avoid obstructions, but it’s useless in low-light conditions, which is LiDAR’s strength.
Vision combined with LiDAR isn’t perfect either, especially for wide-open lawns. Without any reference objects to help a mower orient itself in the world, navigation will fail. And while RTK is the best solution for precise positioning, a mower has no means of identifying obstacles in its way, and its signal is easily obstructed by trees and buildings (ask Husqvarna about that issue).
By combining the three technologies into a single platform, Mammotion claims that true centimeter-level positioning accuracy can be achieved. Such a claim is not new and has been made in marketing for past Vision/RTK-enabled mowers we’ve seen and reviewed. The catch is that you need to set up the mower as closed to the manufacturer’s recommendations as possible, something I’ve yet been able to accomplish in my testing.
Available in the U.S. and U.K. later in 2025
The Mammotion Luba Mini AWD LiDAR (€2,299), which can handle lawns up to 1,500 square meters (0.37 acres), was launched in Europe on July 31. The smaller Yuka Mini Vision (€1,199) is also now available in Europe. It can maintain lawns up to 700 square meters (0.17 acres). Both mowers will ship to the U.S. and U.K markets later this year.
