Drawor: Revolutionizing Construction Layout with Robotics

Automated precision and efficiency redefine modern building practices

The construction sector is experiencing a significant transformation as automation and unmanned solutions become increasingly vital. Traditional manual layout methods, once standard, now struggle to meet the rigorous requirements for accuracy, speed, and safety in contemporary engineering projects. Drawor emerges as a response to these challenges, offering a fully integrated system that minimizes human error and streamlines the construction layout process.

At the heart of Drawor’s innovation is its intelligent collaboration between a drone, a layout robot, and a total station. The drone transports the robot and measurement equipment directly to the site, where the robot autonomously deploys and initiates the layout. This synergy is powered by dynamic dual-track parallel technology and a drone-mounted prism, which together overcome visibility obstacles and achieve millimetre-level precision even in complex environments.

The realization of Drawor is rooted in four core technologies: dual-track dynamic measurement, an electric permanent magnet suction cup, laser SLAM navigation, and 5G real-time control. These elements ensure not only high accuracy but also adaptability to challenging construction sites. The use of carbon fibre for the drone and aerospace aluminium alloy for the robot further enhances durability and performance, supporting digital intelligent construction under demanding conditions.

Drawor’s operational workflow exemplifies automation at its finest. Drones deliver the layout robot and total station, after which the robot autonomously manages the deployment and layout process. Real-time communication between the total station and the drone prism guarantees continuous accuracy, reducing the need for manual intervention and significantly boosting efficiency. This approach not only cuts operational costs but also enhances safety by limiting human exposure to hazardous environments.

Recognized with the Iron A' Design Award in Robotics, Automaton, and Automation Design in 2025, Drawor stands out for its integration of industry best practices and competent technical features. The system’s development involved extensive research, experimentation, and field testing, focusing on overcoming the limitations of traditional equipment and ensuring stability in real-world applications. The result is a robust, scalable solution that sets a new benchmark for digital construction layout worldwide.

Drawor’s success signals a promising future for intelligent construction, where automation and precision drive progress. As the industry continues to evolve, solutions like Drawor are poised to play a pivotal role in shaping safer, more efficient, and highly accurate building practices.
