What is EFLS Technology? A Breakthrough in Robotic Lawn Care
EFLS (Exact Fusion Location System) technology is an advanced positioning system that integrates multiple sensors to offer precise navigation for robotic lawn mowers. Developed to address two major pain points in automated lawn care—low mowing efficiency and complex setup—EFLS enables wireless robotic lawnmowers to operate within virtual boundaries that have an extreme level of accuracy. By replacing traditional boundary wires with virtual mapping, EFLS technology saves consumers time and significantly boosts mowing efficiency, establishing a solid foundation for precision lawn mowing. Positioned within the fields of smart lawn care solutions and automation, EFLS redefines efficiency and user convenience for lawn care enthusiasts, commercial groundskeepers, and facilities managers alike.
The Journey of EFLS: From Basic Positioning to Advanced Multi-Sensor Integration
EFLS technology has evolved through several key stages, each introducing innovations that enhance the accuracy and capabilities of robotic mowers:
EFLS1.0: Wireless and Systematic Mowing
EFLS 1.0 focused on basic RTK (Real-Time Kinematic), Odometer, and IMU (Inertial Measurement Unit) positioning, combining satellite data with gyroscope and accelerometer inputs for reliable boundary-based mowing.
For home lawns across the world, EFLS 1.0 empowers automatic mowers to operate systematically within preset virtual boundaries, delivering a revolutionary mowing experience. This advanced EFLS technology ensures efficient mowing while maintaining a polished, well-kept landscape, elevating the standard for outdoor care.
EFLS 2.0: Multi-Sensor Fusion for Unmatched Precision
EFLS 2.0 is the world’s first visual + RTK solution in the home lawn mower industry. EFLS 2.0 advanced this approach by adding a visual SLAM (Simultaneous Localization and Mapping) system, which constructs a 3D map using a camera. Building on its predecessor, EFLS 2.0 maintains exceptional accuracy even during brief satellite signal losses, leveraging data from gyroscopes, accelerometers, compasses, and odometers. By layering in a 3D visual map generated from a monocular camera, EFLS 2.0 creates a robust positioning system to keep mowers running seamlessly. Powered by deep learning-based feature detection, the mower identifies lighting-invariant feature points in complex environments, significantly boosting stability in fluctuating lighting and environmental conditions.
EFLS 3.0: Expanded Vision and Optimized Precision for Large-Area Mowin
EFLS 3.0 takes precision lawn mowing further, adding left and right camera VSLAM to the existing monocular VSLAM of EFLS 2.0, extending the Field of View (FOV) to a remarkable 300 degrees for even greater reliability. EFLS 3.0 is the first in the industry to integrate VSLAM and VIO with dual RTK antennas, offering a pioneering solution for automated lawn care. Its unique configuration, optimized for large and complex areas, positions EFLS as an industry leader and trendsetter, paving the way for future advancements in robotic lawn mowers.
Coupled with refined VIO (Visual-Inertial Odometry) technology, EFLS 3.0 enhances positional accuracy for seamless navigation in complex spaces. Dual RTK antennas provide superior coverage and accuracy, enabling robust operation in large, complex lawns.
With a triple-camera configuration, EFLS 3.0 doubles the system's visual coverage, empowering mowers to navigate challenging areas—such as narrow passages or low-texture walls—with confidence. The dual RTK antennas further optimize satellite signal reception, while an intelligent algorithm dynamically adjusts primary and secondary base station data, ensuring robust RTK-based positioning stability across vast and segmented lawns.
Why EFLS Stands Out?
Precision Above All Else
Combining RTK with visual localization, EFLS technology achieves centimeter-level positioning, setting a new benchmark in the lawn care industry. The system’s sensor fusion allows mowers to operate in various environments, from open fields to narrow pathways, without sacrificing accuracy.
Differentiating with Dual RTK Antennas and Visual Localization
Through the integration of dual RTK antennas and camera-assisted VSLAM, EFLS provides industry-leading accuracy and expands coverage. This combination is particularly beneficial for large and intricate landscapes, where signal reliability is paramount. Eliminating the hassle of fixing antennas to the wall, while maintaining exceptional accuracy. Additionally, EFLS’s VIO component enhances relative positioning, making it an ideal choice for commercial and residential users who value precision.
Unmatched Benefits of EFLS Technology
User-Friendly and Quick to Deploy
Unlike traditional wired lawn mowers which require boundary wires, EFLS-enabled mowers are ready to go right out of the box. With virtual boundaries and intuitive deployment, users can quickly set up and let their wireless robotic lawnmower operate independently, saving time and minimizing hassle.
Efficient and Sustainable Performance
The system autonomously navigates and maintains accuracy without manual input, allowing for a seamless user experience. With the precise positioning enabled by EFLS, navigation and route planning are optimized, allowing for a systematic mowing path that maximizes efficiency. Thanks to high-precision positioning and efficient cutting, combined with optimized battery performance, the mower achieves significantly greater cutting coverage per charge. Unlike random mowing patterns, the planned cutting path eliminates overlap, maximizing efficiency and effectiveness.
Furthermore, EFLS technology optimizes mowing paths to conserve battery life, reducing the frequency of charging cycles and extending battery longevity. This means more time spent mowing and less downtime, which directly translates to higher energy efficiency and prolonged durability of key components.
Multi-Sensor Precision and Reliability
EFLS technology combines RTK positioning with VSLAM and VIO, allowing wireless robotic lawnmowers to navigate various terrains with accuracy and stability. Unlike traditional systems, which may struggle in satellite-obstructed areas, EFLS continues to perform by relying on visual landmarks for positioning, ensuring uninterrupted operation in complex environments. Thus, it supports various terrains and large open spaces, ensuring consistent performance across residential, commercial, and public landscapes.
With each iteration, EFLS technology moves closer to a vision of fully automated, high-precision lawn care that’s accessible, efficient, and adaptable. EFLS technology redefines automated lawn care through precision, innovation, and robust functionality, shaping a future where intelligent lawn management becomes standard across residential, commercial, and public domains. The future of lawn care is here, and EFLS leads the way.
