Autonomous rebar tying, built for real jobsites
GRID is an autonomous machine that ties rebar directly on the mat, keeping pace with crews on large commercial jobsites. It automates one of construction's most repetitive, injury-prone tasks, delivering consistent, inspection-ready ties that keep projects on schedule and costs down.

Precision Tying
Delivers consistent tie retention and placement.
Autonomous Navigation
Navigates uneven terrain with precision.
Rugged Design
Withstands debris, dust, and rough surface area.
Weather Proof
Operates in rain, snow, and extreme heat.
Data Logging & QA
Logs tie counts, runtime, and reports.
Rapid Integration Precision Execution

GRID fits in any pickup truck bed, SUV, or trailer, and is easy to unload.

GRID is placed on the mat, the operator sets the boundaries, and it's ready to work.

GRID uses computer vision to navigate the mat, detect intersections, and make the ties, all will avoiding obstacles.

When tying is complete, GRID logs the job and the mat is ready for poured concrete.
Autonomy built to transform the jobsite
GRID is Arn's first machine, built to bring autonomy to the jobsite today. It's the start of a growing lineup, and more machines engineered to handle other tedious, manual jobs are already on the roadmap.
