FJ Dynamics Grass Collector

The FJDynamics GC01 Grass Collector Kit is an autonomous sweeping and turf debris management system engineered to integrate with FJD robotic turf platforms (such as the RM21 and Rough Ranger). It utilizes a high-torque rotating roller brush and an integrated hopper to continuously harvest grass clippings, leaves, and loose organic matter across natural turf and synthetic sports fields without requiring manual operator sweeping.

Collection & Sweeping Mechanism Variable-Speed Roller Brush: Features three adjustable rotational speed settings (300, 400, and 500 RPM) to match grass density and debris load. Height Adjustment: Operates across a 20 mm to 50 mm height window to optimize contact pressure and prevent scalping or synthetic fiber disruption. Integrated Hopper: Provides 150 liters (33 gallons) of internal holding capacity for continuous collection cycles. 2. Autonomous Operation & Software Control Integrated Fleet Control: Managed via FJD software, synchronizing travel paths, sweeping speeds, and zone boundaries with the base autonomous mower. Automated Transport & Offloading: Works within mapped transit paths to carry accumulated waste to predetermined disposal zones. Lawn Striping Capability: Includes continuous turf pressure alignment to produce uniform light-and-dark directional striping patterns across sports fields during collection passes. 3. Application Versatility Multi-Surface Design: Functions on natural turf, hybrid grass, and rubber-infill artificial turf without damaging sub-surface backing or dislodging infill materials. Multi-Debris Handling: Collects fresh grass clippings, dry autumn leaf litter, and small surface debris. Commercial Applications Sports Fields & Stadiums: Clipping collection and pitch striping for soccer, rugby, and athletics fields. Golf Facilities: Driving range debris cleanup, fairways, and tournament preparation. Artificial Turf Grounds: Infill grooming and surface debris removal on synthetic athletic surfaces. Municipal & Corporate Parks: Automated leaf collection and high-visibility lawn grooming.
