Quick Answer: Yarbo’s RTK GPS technology redefines robotic lawn mower navigation by providing centimeter-level precision positioning that eliminates the need for perimeter boundary wires, allowing for hands-free, error-free operation even across complex terrains and large properties up to 6 acres.
The future of autonomous yard maintenance lies in precision and freedom. Traditional robotic mowers rely on physical perimeter wires or inconsistent sensors (Lidar/Vision) to operate. Yarbo breaks this barrier using Real-Time Kinematic (RTK) GPS, transforming the mowing experience from complicated setup to seamless automation. This dedicated technology page explains the fundamental difference between wire-free RTK GPS navigation and conventional mowing methods.
Why Traditional Mowing Navigation Fails Large, Complex Lawns
Before advanced AI, robotic mowers faced limitations that restricted them to simple, flat yards. These limitations are primarily rooted in outdated navigation methods:
-
Boundary Wires: Traditional mowers require users to bury or stake perimeter wires. This setup is labor-intensive, easily damaged (by shovels, animals, or weather), and must be re-installed if the yard changes.
-
Lidar and Single Vision Systems: While LiDAR or basic vision systems offer navigation, they suffer from reliability issues, particularly in complex environments. Lidar struggles with dense foliage or fog, and single vision cameras can lose track in rapidly changing light conditions or under heavy tree cover.
The modern homeowner needs a solution that is "wire-free, error-free, and requires zero installation".
How RTK GPS Works in Yarbo Robotic Lawn Mowing
RTK (Real-Time Kinematic) GPS uses a fixed base station and a mobile receiver on the mower to deliver real-time corrections, achieving 1–2 cm accuracy. This allows Yarbo automatic lawn mower with gps to navigate your yard without any physical guides, while adapting dynamically to complex landscapes.

Key Advantage: No perimeter wires, no signal interference from obstacles, no manual remapping.
The Technical Edge: How Yarbo Achieves Centimeter-Level Precision
Yarbo’s navigation is centered on RTK GPS combined with multi-sensor fusion, providing the necessary redundancy and accuracy for complex, real-world conditions. RTK significantly enhances standard GPS by using a fixed base station to correct errors in real-time, delivering accuracy down to the centimeter.
Multi-Positioning Navigation System
Yarbo's navigation relies on a robust combination of sensors:
-
RTK GPS: Provides highly accurate global positioning, crucial for large properties and defining precise edges.
-
IMU (Inertial Measurement Unit) & ODOM Sensors: Compensate for movement when satellite signals are momentarily weak (e.g., under tree cover or near buildings).
-
Binocular Cameras & Ultrasonic Sensors: Enable 360° obstacle detection and real-time mapping of the operating environment, identifying people, pets, or debris.
-
Dual-Antenna System: Helps maintain navigation stability and accurate positioning, eliminating the need for manual calibration.
This fusion of technology ensures smart path planning and allows the machine to operate completely autonomously.

FAQs: Yarbo RTK GPS Navigation
Q1: What does RTK GPS mean for robotic lawn mowers?
RTK GPS (Real-Time Kinematic Global Positioning System) allows the robot to achieve positioning accuracy down to the centimeter level. This level of precision eliminates the need for perimeter wires and ensures accurate mowing and navigation, even near delicate edges or obstacles.
Q2: Can Yarbo’s RTK system work under dense tree cover?
Yarbo uses a multi-positioning navigation system that combines RTK GPS with IMU, vision, and odometer sensors. If the GPS signal is temporarily weakened (e.g., under dense trees), the IMU and cameras help maintain accurate navigation.
Q3: How large of a property can Yarbo manage using RTK GPS?
Yarbo automatic lawn mower with gps is engineered for large residential and commercial landscapes and can manage continuous mowing over an area up to 6 acres (25,000 ㎡).
Q4: Do I need to install a base station for the RTK system?
Yes. The RTK system requires a base station (typically the data center) to receive and process satellite signals, providing the real-time corrections necessary for centimeter-level accuracy.
Q5: How does Yarbo handle steep slopes without boundary wires?
Yarbo utilizes patented all-terrain tracks and a torsion-flexible frame, allowing it to maintain powerful traction and stability on steep, uneven terrain, handling slopes up to 35° (70% grade).
Q6: How often does remapping happen?
Only if you significantly alter your landscape. Yarbo robot lawn mower with gps updates maps in real-time during operation.
