Overview

SmartLine AI is a compact autonomous line-marking robot that uses RTK GPS, a camera and an NVIDIA Jetson Orin Nano to mark football, cricket, baseball and rugby fields with ±1 cm precision. Select a field template, press start, and it plans, paints and returns to charge — replacing hours of manual string-and-wheel marking.

RTK GPS + camera guidance for ±1 cm line accuracy
Templates for football, cricket, baseball, rugby and more
AI obstacle avoidance and field-boundary detection
8–10 h battery, 60 × 40 × 40 cm and portable

The problem

Groundskeepers at schools, clubs and municipalities spend hours every week marking fields by hand with strings, tapes and push markers. Results vary, paint is wasted, and staff time is expensive. Larger robotic markers exist but are costly and bulky for smaller facilities.

Use cases

Weekly field re-marking

Repaint existing lines automatically, following the previous marks with camera guidance.

New field layouts

Mark a full football or rugby pitch from a template in minutes, aligned to RTK coordinates.

Multi-sport facilities

Switch between football, cricket, baseball and athletics layouts on the same grounds.

Schools and municipalities

Free groundskeepers from manual marking across many sites.

Stadiums and events

Mark logos, event zones and temporary layouts accurately.

How it works

1
Scan
The robot scans the field with its camera and RTK GPS to detect boundaries and existing lines.
2
Plan
AI generates an accurate line plan from your chosen template and field dimensions.
3
Mark
The robot drives the plan and sprays lines with ±1 cm precision, avoiding obstacles.
4
Monitor
Progress, paint level and battery are shown live in the app.
5
Return
When finished, SmartLine returns to its base for charging and storage.

In the app

SmartLine AI FAQ

General FAQ

Is the $49 reservation deposit refundable?

Yes. The $49 deposit is fully refundable any time before your unit ships — email hello@iemilabs.com or use the refund link in your confirmation email. It is credited in full against the purchase price, and reserving creates no obligation to buy. Payments are processed securely by Stripe.

Is my data processed on the device?

Navigation and obstacle detection run on the robot. Camera images are used only for driving and are not stored or uploaded; only job progress and telemetry are sent to the app.

Do I need an RTK base station?

No. SmartLine uses network RTK corrections (NTRIP) over LTE in most regions. A portable base station option is planned for areas without coverage.

Is it safe around people?

SmartLine detects people and objects and stops or reroutes. It also has physical bumpers and an emergency stop, and is designed to be supervised from the app.

Which paint does it use?

Standard water-based field-marking paint, mixed to your usual ratio.

Is SmartLine AI available now?

SmartLine AI is in development. Specifications shown are target specifications and may change as we complete engineering validation. We are targeting a Q4 2027 ship window and will email reservation holders with every major milestone.

What warranty will it come with?

We are planning a 2-year limited hardware warranty covering manufacturing defects, with advance replacement for pilot and business customers. Final warranty terms will be published before shipping begins.
