How it works on your site
The WJ Group Robotic PreMarker is an 18 kg wheeled robot that autonomously sprays temporary pre-marking dots and lines on road carriageways, following a GNSS-guided digital marking plan loaded via USB. It covers one subtask within the roads and pavements job: layout and measurement for highway surface works, including centre lines and car park bays; final line application, symbols, and other marking patterns stay with the crew. The Robotic PreMarker has been in production deployments since 2018 across six confirmed UK highway schemes for contractors including Balfour Beatty and Costain/Galliford Try.
Layout and Measurement
The robot loads a digital marking plan in CSV or DXF format from a USB key and follows GNSS coordinates to spray temporary pre-marking positions on the carriageway. The operator stays inside a vehicle behind the traffic management closure while the robot traverses the work zone. Final permanent line application, symbols, hatching, and complex junction geometry remain crew work.
