Robot Lawn Mower Technology Explained: How It Works
Real-Time Kinematic (RTK) technology revolutionizes the navigation of robot lawn mowers, enhancing their precision significantly. By combining satellite data with corrective signals from a stationary ground-based antenna, RTK narrows down the mower's location from a few meters to just a few centimeters.
This advancement eradicates the need for boundary wires in lawns, allowing the mowers to move in a logical, ordered fashion, rather than simply going around randomly. While global navigation satellite systems (GNSS) alone provide adequate location data, RTK provides up to 100 times greater accuracy compared to smartphone GPS [1][5].
The enhanced accuracy results in the mowers steering precise paths, aligning closely with obstacle edges, and maintaining consistent mowing patterns across the lawn. This improved precision enables them to reliably navigate within predefined zones without the need for physical perimeters, providing boundary wire-free operation and enhancing safety near sidewalks, drainage ditches, or other landscape features [1][5].
The technology utilizes a fixed, antenna-equipped base station with known coordinates, distinct from the robot lawn mower's charging station. Both the RTK station and the mower connect to satellites in the sky to achieve optimal navigation. The RTK station should be placed with a wide and unobstructed view of the sky as possible to ensure seamless signal transmission [2].
It is essential to note that the effectiveness of RTK positioning is dependent on several factors. Overhead obstructions like trees, buildings, or insufficient satellite coverage, can impact the system's performance. Despite this improvement, some users may still encounter challenges such as unmown strips of grass or areas missed during mowing, requiring ancillary navigation systems as backup when signal quality is poor [3].
