The construction sector faces growing labor shortages while demand for building renovation and new housing continues to rise. At the same time, tasks such as plastering and surface coating remain physically demanding and difficult to automate. LAYERED addresses this challenge with a lightweight mobile robot that automates surface finishing directly on construction sites. The system scans walls and allows workers to select the surfaces to be treated through a simple interface, after which the robot applies plaster or coatings with consistent quality. Designed to integrate seamlessly into existing construction workflows, the system reduces manual effort and material waste, helping the industry meet growing construction and renovation needs despite limited labor.
