Japanese construction company Takenaka Corporation, in collaboration with other partners, will conduct a demonstration experiment combining autonomous vehicle transportation and drone flight in December. This initiative will take place in Yumeshima in Osaka City, the construction site for the EXPO 2025 Osaka, Kansai. The project aims to enhance productivity and reduce manpower on construction sites by transporting materials within the site using autonomous vehicles and delivering them directly to workers by drones.

This experiment is part of the Ministry of Land, Infrastructure, Transport and Tourism's 3D urban model initiative, "Project PLATEAU." The autonomous vehicle transportation system is being developed in partnership with Tokyo-based start-up ADAWARP Japan, while the autonomous drone flight system is being developed with SENSYN Robotics.

Among the prior experiments, the autonomous vehicle transportation system was tested on public roads in Osaka City. Vehicles equipped with LiDAR, which measures distances to buildings, navigated through a 3D virtual model of the city, efficiently creating a point cloud map. This map allowed for accurate self-positioning in the real world, confirming the feasibility of autonomous driving. This marks Japan's first autonomous driving system utilizing a 3D urban model.

For the autonomous drone flight experiment, GPS, LiDAR, and Visual Inertial Odometry (VIO) technology, which calculates movement by capturing continuous changes in camera images, were integrated. In areas where GPS accuracy declines, VIO ensured precise positioning through image analysis. The results confirmed that drones could safely and accurately navigate both indoors and outdoors, even among high-rise buildings. (2024/07/19)
