robotmaaiers

Robotmaaiers are autonomous lawn mowing devices designed to cut grass with minimal human intervention. They are usually powered by rechargeable batteries and use rotating blades to trim the turf. They come in consumer models for home lawns and more capable units for large properties or complex landscaping. The typical design aims to balance cutting efficiency with safety and low noise.

Navigation and cutting

Most models use a perimeter setup such as a buried boundary wire to define the mowing area; some newer models use GPS-based mapping and onboard sensors to plan routes and stay within defined zones. They detect obstacles, slopes, and drops with bump, tilt, or infrared sensors, and automatically adjust speed and path.

Operation and features

They automatically start on a schedule or when activated, dock at a charging station when battery is low, mulch clippings to return nutrients, offer adjustable cutting heights, and can be controlled via smartphone apps or integration with smart home systems. Some models include rain sensors or weather-based scheduling.

Safety and maintenance

Standard safety features include blade braking when lifted or tilted, safety switches, and obstacle detection. Regular maintenance includes blade replacement, cleaning sensors, battery care, and cable checks for boundary systems.

History and market

Since the 1990s, robotic mowers have evolved from experimental designs to widely available consumer products, with multiple manufacturers expanding features such as GPS navigation, intelligent mowing patterns, and connectivity. They are popular for low-noise operation and reduced manual effort but may be challenged by very irregular terrain, tall grass, or large slopes.
