Professional Autonomous Turf Care
FJD RM21 Multi-Functional Commercial Robotic Mower
Autonomous commercial mowing with RTK + LiDAR navigation, intelligent path planning, multi-zone management, automatic charging, remote app monitoring, and an expandable professional turf-care platform.
Current DRT Package Configuration
Y0100006 RM21 × 1 + 00040038 2 kWh Battery × 2
Built to Automate Large-Scale Turf Maintenance
RM21 is designed for professional mowing applications such as golf courses, sports fields, orchards, municipalities, campuses, and other large managed properties. Instead of manually driving a mower across the same areas every day, operators can create digital work zones and let RM21 execute repeatable mowing tasks automatically.

From Mapping to Autonomous Mowing
How Does the RM21 Work?
The mower first learns where it should work. After mapping and task setup, RM21 follows planned routes using RTK + LiDAR, detects obstacles, and can return for charging automatically.
Map the Area & Plan the Route
First, create the digital mowing area. RM21 can then automatically generate organized working routes inside the defined boundary.
Instead of wandering randomly like many residential robotic mowers, RM21 follows planned passes to reduce overlap and missed areas.
Divide the Property into Zones
A large property does not need to be treated as one giant mowing area. Individual fields, fairways, rough areas, or turf sections can be organized as separate digital work zones.
RM21 can execute a single task across multiple zones, simplifying management of larger commercial sites.
Configure & Schedule the Job
Use the supported app workflow to manage the mower, review maps and job history, and create future mowing schedules.
Navigate with RTK + LiDAR
RM21 combines RTK positioning with LiDAR sensing to support precise and stable autonomous navigation.
LiDAR is especially useful in environments such as beneath trees or around structures where satellite positioning can become challenging.
Detect Obstacles During Operation
Real-time 360° LiDAR helps detect objects around the machine while it follows its autonomous route.
Front and rear physical bumpers provide another layer of protection for commercial operating environments.
Automatically Return to Charge
When the battery becomes low, RM21 supports automatic return to its charging station.
This reduces manual battery handling and supports longer, scheduled autonomous mowing workflows.

Connectivity Explained
Does RM21 Need Wi-Fi or Internet?
Navigation and network connectivity serve different purposes. RTK + LiDAR are the core navigation technologies, while network connectivity supports setup, app, remote management, and related services.
The exact RTK, network, antenna, and charging configuration depends on property size, terrain, tree coverage, and deployment method. Contact DRT before installation to confirm the recommended site configuration.
Optional Terrain Upgrade
Optional Dual Rear Tires
For slopes and uneven ground, RM21 can use optional dual rear tires to provide additional traction and stability.
Standard Setup
Standard Rear Wheels
Suitable for typical commercial turf conditions.
Optional Upgrade
Dual Rear Tires
Additional tire contact helps improve grip and stability on slopes and uneven ground.
Optional equipment. Contact DRT to confirm availability, compatibility, mounting hardware, and installation requirements.

One Robot. Multiple Jobs.
More Than Just a Mower
RM21 is designed as a modular professional turf platform. Optional attachments allow the same robotic base to perform additional maintenance tasks.
Attachments are optional and may be sold separately.
Application Scenarios
Designed for Professional Turf Environments
Advanced Golf Course Workflow
From Site Data to Autonomous Mowing

Mowing-area figures are theoretical values under standard test conditions. Actual coverage depends on operating hours, terrain, grass conditions, cutting height, slope, charging configuration, and other site conditions.
On slopes, routes should generally be planned uphill and downhill. Cross-slope mowing should be avoided or performed with caution.
Always inspect the work area before autonomous mowing. Obstacle-detection performance can vary with object size, grass height, terrain, lighting, and movement.
RTK equipment, antennas, network configuration, charging equipment, optional attachments, software services, and installation requirements may vary by project and package. Contact DRT to confirm the complete configuration before deployment.
Professional Robotic Turf Care
Automate More. Maintain Smarter.
