「We have been developing an automated spraying device, the SOSEI Line Robo, that operates on metal roofs. The device serves as a labor-saving solution to the construction industry’s common challenge of securing skilled workers amid Japan’s declining birthrate and aging population. Specifically, it automatically applies coating smoothly from the upper end to the lower end, which was previously impossible to do manually, improving construction speed and quality. The device can also be operated by workers with limited experience (patent application filed).」
The Line Robo’s functions for improving construction speed and quality through automated coating, and for enabling use by less-experienced workers, have been specified, and a patent application has been filed. - 2026-05-13AdvancedFinancial results briefing materials
