The Toknav TR10 is a GNSS-guided pre-marking robot that autonomously paints layout lines, curves, dots, numbers, and letters onto road, airport, and infrastructure surfaces using RTK positioning for centimeter-level accuracy. It runs on a battery-powered wheeled chassis with a paint/slurry hopper, is steered via one-click drawing import of pre-designed plans, and is built to cover ground several times faster than manual marking crews.
