Scope of Work & Technical Specifications
1. Purpose and Overview
The Enfield Department of Public Works, Buildings & Grounds Division is seeking competitive proposals
from qualified vendors to furnish, deliver, and support an autonomous, GPS-guided robotic field painting

optimize paint resource usage.
2. Minimum Technical & Performance Specifications
The proposed robotic system must meet or exceed the following engineering and operational
requirements:

* 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.
B. Software and Field Customization
* 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

* 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.
