2. Minimum Technical & Performance Specifications

The proposed robotic system must meet or exceed the following engineering and operational requirements:

A. Navigation and Guidance System

• GPS Precision: Must utilize Real-Time Kinematic (RTK) GPS, cellular network correction, or a local base station to guarantee a line placement accuracy of ± 1 inch (2.5 cm) or better.

• Signal Continuity: System must possess the ability to maintain line straightness and operational continuity during brief satellite or cellular signal degradation.

• Safety Features: Equipped with mechanical bumpers, lidar, optical sensors, or automatic software geofencing that immediately shuts down the machine upon encountering obstacles, pedestrians, or boundary violations.

• Layout Library: Software must include pre-programmed, standard dimensions compliant with NFHS, NCAA, and FIFA regulations for sports including, but not limited to: Football, Soccer, Lacrosse (Men's and Women's), Field Hockey, Baseball/Softball, and Track/Rugby geometries.

• Customization: Operator must be able to resize, shift, rotate, and combine multi-sport fields simultaneously using a mobile application or tablet interface.

• Cloud Storage: System must sync field layouts to the cloud, allowing identical fields to be re-painted season after season without repeating the initial measurement/pinning layout process.

C. Mechanical, Paint, and Battery Capacity

• Drive System: Must feature a rugged, low-impact wheel or track system capable of navigating wet turf and standard slopes without damaging the grass surface.

• Paint Delivery: Must utilize a high-pressure, airless spray system compatible with industry-standard, bulk concentrated or ready-to-use robotic field paints.

Automated, GPS-Guided Robotic Field Marking System 7
