The first robot mason in Slovenia was presented in Cerknica

A groundbreaking innovation has arrived on construction sites across Slovenia with the introduction of a bricklaying robot known as WLTR. This technology marks the first instance of robotic bricklaying being demonstrated in the country, taking place in the town of Cerknica. The robot, which has been used on European construction sites for several years, represents a significant step forward in the automation of construction processes. It can lay bricks at a speed of up to ten square meters per hour and reach a height of 3.5 meters without requiring scaffolding. Its operation requires only one operator and an assistant, and according to its manufacturer, it can replace the work of a multi-person masonry team in certain projects. This presentation aligns with a broader trend toward automating construction, driven by labor shortages and the need for increased productivity across Europe.

The WLTR robot is designed to automate the laying of bricks and works in collaboration with construction teams. Initially, an experienced bricklayer lays the first row of bricks, after which the robot takes over from the second row onward. Utilizing sensors, the robot checks the position of each brick and makes necessary adjustments, achieving millimeter-level precision. This level of accuracy ensures consistent quality and reduces the physical strain typically associated with manual bricklaying.

The system operates using electrical power (400 V) and requires one trained operator and one assistant worker. According to the company behind the robot, in specific scenarios, it can replace a team of five to six bricklayers, particularly during physically demanding tasks. Amel Emkić from the Wienerberger group emphasized that robotic bricklaying does not replace human knowledge and experience but rather addresses challenges within the construction industry. He noted that today's construction sites demand faster execution, uniform quality, greater safety, and better organization of work. The robot handles the most physically demanding part of the job, while essential professional expertise remains in the hands of humans. Emkić highlighted that robotics will not eliminate the trade of bricklaying but will transform it.

To facilitate automated bricklaying, the system uses specially developed, finely finished bricks featuring additional grooves for precise handling and placement. These features enable stable and repeatable automated bricklaying. The WLTR robot has already been employed in more than 40 commercial projects across Europe, ranging from residential buildings in the Czech Republic, kindergartens in Poland, industrial warehouses in Austria and Hungary, to family homes in the United Kingdom.

The introduction of this technology in Cerknica underscores a growing shift towards automation in the construction sector. As labor shortages continue to challenge the industry, solutions such as the WLTR robot offer potential relief by increasing efficiency and reducing the physical burden on workers. However, the integration of such advanced machinery also raises questions about the future role of traditional trades and the need for new skills among workers. While the robot enhances productivity and consistency, it necessitates a reevaluation of how construction projects are managed and executed.

As the use of robotic systems becomes more widespread, their impact on the construction landscape could be profound. Companies like Wienerberger and Tosidos, which have partnered to showcase the WLTR robot, are likely to play a pivotal role in shaping the adoption of such technologies. Their efforts reflect a strategic move to address current industry challenges while preparing for future demands. With continued advancements in automation, the construction sector may witness a transformation that balances technological progress with the preservation of skilled craftsmanship.
