ROLE

The original strain-wave (harmonic) gear house. Its proprietary flexspline metallurgy-and-grinding process — still a trade secret — defined the high-end reducer category that every precision robot joint depends on.

CHOKE POSITION

Near-monopoly of high-end strain-wave reducers for decades; the single cleanest chokepoint asset in physical AI. But the harmonic segment is exactly where the Chinese challenge (Leaderdrive) is landing first, so the name with the most humanoid upside is also the most exposed to share loss.
