The FJ Dynamics RM21 Robotic Mower is a fully autonomous, high-capacity mowing solution designed for large-area turf management. Purpose-built for sports fields, sod farms, golf courses, estates, campuses, and commercial landscapes, the RM21 delivers consistent cutting quality with minimal labor requirements.

With advanced navigation, intelligent mapping, electric drive, and a highly durable design, the RM21 represents a new standard in professional turf automation. It handles expansive open turf, varying terrain, environmental challenges, and multi-zone mowing with ease — all while keeping operational costs low and turf quality high.

Key Features & Benefits

🚀 Fully Autonomous Mowing

• Combines RTK GNSS positioning and LiDAR navigation for centimeter-level accuracy.

• Wire-free operation—no perimeter boundary wires required.

• Automatically creates optimized mowing routes and manages multiple mowing zones.

• Returns to the docking station for charging when needed, then resumes work automatically.

🌳 Advanced Terrain & Obstacle Handling

• Full 360° obstacle detection using LiDAR and integrated sensors.

• Collision bumpers, lift and tilt sensors, and rain detection enhance operational safety.

• Designed to operate reliably across varying terrain, including slopes up to 20° and uneven turf.

📱 Smart Remote Management

• Control and monitor the RM21 via a mobile app.

• Set mowing schedules, view progress, adjust mowing zones, and manage multiple fields remotely.

• Ideal for managers overseeing large properties or multi-site operations.
