FJ Dynamics PaintMaster Pro

The Sveaverkin Paintmaster Pro is an autonomous, commercial-grade sports field line marking robot engineered for automated field painting across athletic complexes, municipal parks, schools, and sports clubs. Powered by Real-Time Kinematic (RTK) GNSS positioning, the unit dispenses turf paint along digitally mapped field templates with centimeter-level precision, eliminating the need for manual string lines, manual surveying, or traditional hand-pushed marking equipment.

Core Systems & Architecture

1. Navigation & Layout Precision

• RTK GNSS Guidance: Connects with RTK base stations or network RTK (NTRIP) to achieve sub-inch line precision on straightaways, center circles, arcs, and penalty boxes.

• App-Based Layout Templates: Features standard pre-configured layouts for soccer, American football, rugby, field hockey, lacrosse, track events, and custom lines or logos.

• Obstacle & Boundary Detection: Built-in collision sensors and optical detection pause operation when dynamic objects or personnel cross the active path.

2. Paint Dispensing Mechanism

• High-Pressure Spray Assembly: Employs a pressurized pump and specialized spray nozzle designed to atomize field-marking paint evenly without clogging or overspray.

• Flow Rate Synchronization: Automatically adjusts paint pump pressure in real time based on vehicle ground speed to ensure uniform color density throughout the run.

• Quick-Clean / Flush System: Built with accessible fluid lines and quick-connect couplings to facilitate fast paint refills and post-operation flushing routines.

3. Software & Field Management

• Mobile App Control: Operators select field types, adjust line dimensions, set starting orientations, and initiate automated painting runs via tablet or smartphone.

• Path Memory & Resume: If paint runs low or a job is interrupted, the platform records exact coordinates, allowing the robot to resume spraying at the exact stopping point without overlap or gaps.

• Multi-Field Batch Mapping: Saves custom field layouts to memory for repeatable seasonal layouts across multi-pitch complexes.

Commercial Applications

• Sports Complexes & Stadiums: High-precision marking for soccer pitches, lacrosse fields, and multi-sport venues.

• Schools & Universities: Automated line painting for athletic tracks, practice grounds, and seasonal tournament fields.

• Municipal Parks & Rec Departments: Unmanned marking for public park facilities and intramural grounds.

• Event & Exhibition Turf: Custom outdoor boundary marking and temporary event grid layouts.
