Robot Lawn Mowers: GPS, RTK and Design Drive Modern Performance
Modern robot lawn mowers have moved beyond boundary wires to rely on GPS paired with Real‑Time Kinematic (RTK) beacons for centimeter‑level accuracy. Companies such as Husqvarna explain how RTK tells satellites "I'm always here," allowing the mower to correct GPS drift. Design factors like cutting width, camera‑based obstacle detection, and scheduling features affect how well these devices handle narrow paths, nighttime operation, and weather delays. Real‑world testing revealed challenges with obstacles like trampolines, tree roots, and pets, while GPS coverage varies between suburban and urban settings. Overall, the technology offers reliable mowing with some human oversight needed.
