The work problem
Kajima needed to address construction labor shortages and reduce engineers' repetitive rounds, visual documentation and three-dimensional surveying. Structures and material layouts change as construction advances, making controls customized for fixed environments difficult to reuse. The company needed robots to collect routine site data while engineers concentrated on safety, quality and schedule judgments.
Technology and data
The company mounts a FieldAI autonomy unit containing cameras, LiDAR and an edge AI device on robots. Its FFM model processes images and point clouds on the device, combining physics-based reasoning and uncertainty assessment to choose travel directions. A robot explores an unfamiliar area and creates a map, then avoids obstacles while collecting photos and point clouds and updating the map. It returns to its charging station and uploads data for web access. Staff can specify a location and view live video, while people retain technical judgment and safety management.
Results
Kajima reports deployment at more than 10 Japanese construction sites in roughly a year following an enterprise service agreement in 2025, and more than 2,000 autonomous missions across robot types, tasks and sites. It describes continuous use on active sites with daily environmental changes, rather than restricted demonstrations. Automatically captured photos and point clouds make construction status and dimensions available for progress management.
Limits and open questions
The source gives no site-level staffing, time-saving or accident-reduction rates. It identifies the year of the agreement and expanded deployment but not its starting month, so publication date is used for ordering.
