Legend Robot presents its autonomous mobile spraying fleet at CONEXPO-CON/AGG in Las Vegas, its entry into the North American market with a portfolio of robotic systems designed for interior commercial construction. The company positioned its technology as a response to ongoing skilled labor shortages and rising construction costs across the region. Legend Robot’s systems are built around what it describes as “Physical AI,” a form of artificial intelligence designed to interact with and adapt to physical environments. The technology is intended to reduce reliance on manual labor while addressing safety concerns in construction settings.
At the center of the launch are two models tailored for commercial applications: a 6.2-meter latex painting robot and a 6.2-meter putty spraying, or skim coat, robot. The units are equipped with the company’s third-generation mobile continuous spraying technology, which enables the machines to operate while in motion rather than from a fixed position.
According to the company, the robots use real-time 3D sensing and dynamic path planning to support continuous spraying across high ceilings and large commercial surfaces. Legend Robot states that the systems are capable of single-pass coverage on complex curved surfaces and are designed to reduce the need for manual rework. The company reports that the technology can increase operational efficiency by 50 percent and reduce construction costs by more than 60 percent.
“We are bringing a solution that bridges the gap between robotic innovation and on-site execution,” said Jason Liang, marketing director at Legend Robot. “Legend Robot is no longer just about spraying; we are building a comprehensive smart construction ecosystem.”
As part of its 2026 product roadmap, the company outlined plans to expand beyond spraying systems to include additional robotics for construction workflows. These include high-precision tile-laying robots that use LiDAR for alignment and navigation, as well as heavy-duty floor grinding robots intended to support surface preparation with limited human oversight. Legend Robot said its broader objective is to provide general contractors with a scalable suite of robotic systems aimed at supporting project timelines and standardizing finishing quality across commercial and residential construction projects.
