It easily handles slopes up to 20° and can be monitored or controlled from anywhere through the mobile app.
Tech-Driven Lawn Care Reimagined
Accurate and Efficient Mowing
Cut grass with centimeter-level positioning accuracy, giving efficiency a boost while reducing the risk of mowing lapse, mowing task omission or repetitive working.
For sports applications, the RM21 can also be paired with the Line Marker Kit, allowing one machine to both mow the turf and mark field lines with high precision—saving even more time and labor.

Automatic Mowing on Complex Terrain
Leverage LiDAR tech to create a 3D map of the terrain, making it a breeze to safely mow in challenging areas such as under trees or around objects.

One-Click Multi-Field Management
Support mowing multiple zones in a single task to save your valuable time & effort in managing your property, helping you invest more time on critical tasks.

Smart Path Planning
Plan optimal mowing paths automatically with built-in precision algorithms, relieving your anxiety when working on the labor-intensive mowing tasks.

360° Real-time Object Detection
The mower leverages advanced LiDAR technology to detect objects in its surroundings, eliminating blind spots with impressive accuracy. It uses this spatial awareness to react quickly and avoid obstacles before collisions can occur. This rapid obstacle-detection system adds a powerful extra layer of safety to every operation.
Comprehensive Protection
The mower is protected by collision bumpers, which shield it from unexpected impacts. It also includes lift-safety features to detect and respond if it’s raised from the ground. Meanwhile, rain sensors monitor weather conditions to ensure safe, uninterrupted mowing.


Easier and Smarter Mowing
Take full control of your mower from anywhere using the mobile app, giving you real-time access even when you're away. You can easily monitor its status and adjust mowing schedules remotely. This flexibility keeps your turf management seamless and hassle-free.

Power You Can Count On
When the battery runs low, the RM21 automatically navigates back to its charging base to recharge. This self-docking feature minimizes downtime and significantly improves overall working efficiency. Once fully charged, it seamlessly resumes its tasks to keep operations running smoothly.

Confident Performance on Any Slope
Save Time and Money
The RM21 + LM01 Combo from FJ Dynamics dramatically cuts both labor and material costs by combining mowing and line-marking into a single autonomous machine. By eliminating the need for separate crews and equipment, it can reduce labor costs by over 90% and cut paint usage by more than 50%.
