Mammotion is using the spotlight of the IFA 2025 trade show in Berlin to introduce what it calls a major breakthrough in robotic lawn mower navigation: the Tri-Fusion Positioning System. This platform combines LiDAR, Real-Time Kinematic (RTK) satellite positioning, and vision-based navigation into a single integrated system. While robotic mowers have long relied on pairings of these technologies—such as LiDAR and RTK, or vision and LiDAR—the industry has typically used them in parallel rather than as a unified approach. Mammotion claims Tri-Fusion is the culmination of nearly a decade of development and represents a leap toward consistent, centimeter-level accuracy in a wide range of environments.
The company stresses that each navigation method comes with its own strengths and shortcomings. Vision systems excel at recognizing and avoiding obstacles, but their effectiveness drops significantly in dim lighting. LiDAR, on the other hand, maintains performance in low-light conditions but struggles to orient itself properly on open, featureless lawns. RTK delivers the most precise positioning of all, but the system is highly sensitive to obstructions like trees and buildings, often leading to signal dropouts. By layering these three methods together into a cohesive system, Mammotion aims to minimize the blind spots of each individual technology and create a more reliable navigation framework for its autonomous mowers.
The first products to receive Tri-Fusion will be Mammotion’s Luba Mini AWD LiDAR and Yuka Mini Vision, both launched in Europe earlier this summer. The Luba Mini AWD LiDAR, priced at €2,299, can handle lawns up to 1,500 square meters (0.37 acres), while the smaller €1,199 Yuka Mini Vision is designed for lawns up to 700 square meters (0.17 acres). Mammotion says Tri-Fusion will be made available through firmware updates to these models, in addition to being a native feature of several upcoming mowers that have not yet been announced.
According to Mammotion CEO Jayden Wei, the system is meant to adapt equally well to small city gardens and large country lawns, performing consistently across shaded, obstructed, or uneven terrain. While some skepticism remains—similar claims of centimeter-level accuracy have appeared in past mower marketing—the combination of all three navigation technologies into a tightly integrated platform is a unique step forward. The updated models will begin shipping to the U.S. and U.K. later in 2025, signaling Mammotion’s intent to challenge established players like Husqvarna in the growing robot mower market.
