FJDynamics RM21 - Commercial Robotic Mower for Turf Care

Unleash the next era of commercial turf maintenance with the FJDynamics RM21 - a professional, fully electric autonomous mower engineered for large properties where consistency, labor efficiency, and precision matter. Built for sports fields, golf applications, turf farms, and large estates, RM21 pairs smart route planning with RTK positioning and LiDAR awareness to deliver repeatable cuts—day after day, zone after zone. Precision mowing that stays on track RM21 uses RTK + LiDAR fusion to maintain reliable navigation—even in challenging signal environments like tree cover—while intelligent path planning optimizes coverage inside your defined work areas. Manage multiple zones, set schedules, and monitor status via app-based controls for hands-free, predictable mowing across large sites. Commercial coverage for big properties Designed for scale, RM21 is rated for up to ~3 acres per charge and up to ~23 acres over three days (with higher 72-hour coverage listed depending on charging configuration). It’s also built to handle real terrain with up to a 20° climbing ability and speeds up to 3.7 mph. Rugged, safe, and low-interruption RM21 supports “set it and forget it” operation with smart docking/auto return for charging when battery is low, plus safety-focused sensing and protection features. FJDynamics highlights 360° LiDAR obstacle detection, physical bumpers, lift protection, and rain monitoring for safer unattended operation. The RM21 Add-On Ecosystem Turn one Robot into a Turfcare Team One of RM21’s biggest advantages is expandability: add purpose-built modules to move beyond mowing into collection, dew control, line marking, and ball picking—ideal for sports complexes, golf facilities, and multi-field venues. Ball Picker Kit (BP01): Automated ball collection (driving ranges) Turn RM21 into a hands-free range assistant. BP01 supports automatic return to the unloading point when baskets are full, real-time monitoring, and multi-robot coordination for full-course coverage. Capacity is listed at two baskets, 400 balls per basket, with a ~35" picking width. Line Marker Kit (LM01): Crisp, repeatable lines with less paint For sports turf teams, the LM01 kit is built to cut time and reduce waste. FJDynamics claims it can reduce paint usage by 50%+, cut labor costs by up to 90%, and mark up to 20 full-size fields per charge, with support for multiple field layouts (football, rugby, baseball, and more). Grass Collector Kit: Mow + collect in one pass Perfect for facilities that want a cleaner finish without extra labor. GC01 is positioned to collect clippings and fallen leaves while mowing (or perform an intelligent post-mow sweep), and it also calls out artificial turf debris clearing and striping control for a professional presentation. Specs list ~33 gallons max collection volume and ~31.5" collection width. Dew Brush Kit (DB01): Dew control for truer roll and cleaner turf For early-morning golf and sports turf routines, DB01 focuses on consistent presentation. It supports smart lifting and folding to avoid impacts during turns and transitions, with customizable brushing direction to clear dew evenly. The brush system extends to ~115" in the three-section configuration. Media
