Overview
The RM21 robotic mower is an autonomous turf maintenance platform designed for large multi-zone areas such as sports fields, golf courses, turf farms and orchards. It provides consistent, precise cuts and advanced autonomous functions including site mapping, multi-zone scheduling and remote monitoring to optimize mowing operations and reduce manual work.

Key Features

• Intelligent path planning: automatically calculates optimal routes within defined work areas for consistent coverage.
• Multi-zone management: schedule and run tasks across multiple zones for large sites.
• Remote app monitoring: create maps, manage schedules and monitor status from a smartphone.
• RTK + LiDAR fusion: reliable positioning and navigation under trees and in challenging signal environments.
• Multi-layer safety: 360° LiDAR obstacle detection plus front and rear bumpers for safe autonomous operation.
• Smart docking & charging: automatic return-to-charge when battery level is low.
• Modular task kits: optional kits for ball collection, line marking, grass collection and dew brushing.

Applications & Use Cases

• Sports fields (soccer, football, rugby) — consistent mowing with reduced labor requirements.
• Golf courses — maintenance for greens, fairways and driving ranges with multi-zone scheduling.
• Orchards and turf farms — autonomous mowing across large continuous areas.
• Stadiums and municipal turf — time-constrained maintenance including line marking and debris collection.
