SkyDrive is developing the cargo drone for use in industries that carry heavy materials on complex terrain such as slopes, mountain valleys, overpasses, power transmission towers, civil engineering/construction sites, agricultural fields, etc.

Usage of cargo drones will help avoid dangerous works, save personnel and shorten the term of works. Hence SkyDrive can contribute to responding to labor shortages and improving Japan’s labor productivity sagging due to its declining population.
