Robot Field Painting and Mowing for Every Sport

The FJD RM21 Robotic Mower is a versatile, professional-grade solution tailored to maintain and elevate turf across a variety of sports contexts — from football pitches to golf courses. With centimeter-level RTK + LiDAR precision, the RM21 can navigate complex terrain with exacting accuracy, ensuring the playing surface is kept consistently smooth and even. Its app-based multi-zone scheduling allows it to manage large or multiple fields in a single run, making it ideal for grounds that host multiple sports. The mower’s safety systems — including 360° object detection, collision bumpers, and rain sensors — protect both the machine and the delicate turf, while its ability to climb slopes up to 20° means it can handle undulating fairways or the variable grade of a sports field. Because it’s pure electric and automatically returns to its charging station when the battery runs low, the RM21 offers a quiet, sustainable way to maintain premium turf without interrupting play.
