ROI Calculation Logic

For high-altitude and confined-space infrastructure inspections, assuming 3 workers for 100 days/year at $1.5K/day (AI est.) for labor and special equipment. Implementing this technology could enable 1 worker to complete the same task in 50 days. This projects a total annual cost reduction of ~$400K (AI est.). After initial investment amortization, a net annual saving of ~$150K (AI est.) is anticipated.

Speed to Market
6× faster than in-house development
This technology, invented by the Railway Technical Research Institute, is presumed to have completed basic technical verification. As it is already patented, licensees can bypass the initial R&D phase, focusing directly on integration with existing robotics and drone platforms. This could shorten time-to-market by approximately 2.5 years compared to developing a similar hybrid UAV in-house.
