HP has put forward a small robot it says can dramatically speed up construction work, by autonomously printing guidelines straight from the blueprints onto the floor. Rugged, roadworthy and extremely accurate, Siteprint is a super-quick layout tool.

The robot replaces the time-consuming manual process of site layout, using a variety of different inks to place precise lines, exact curves and faithful reproductions of complex shapes on all kinds of floors, from porous surfaces like concrete and plywood to terrazzo, vinyl or epoxy.

It doesn’t require a perfectly smooth or clean floor – indeed, it can handle a certain degree of surface irregularity and obstacles up to 2 cm (0.8 in) high. It runs built-in obstacle and cliff drop sensors for fully autonomous operation, and will work around barriers even if they’re not in the plans.

As well as layout lines, it’s capable of printing more or less whatever else you need on the floor too, including text notes. Operators set it up using cloud-based tools for job preparation, fleet management and tracking, and can run it on site with a touch-screen tablet and a tripod-mounted “totalstation.”
