## Summary

The RV-135, the first model in Nabtesco's RV series of precision reducers for industrial robots developed in 1985, has been selected by the National Museum of Nature and Science of Japan as a 2026 "Important Historical Materials for Science and Technology (Future Technology Heritage)" and has completed registration. The model uses a unique structure combining a cycloidal mechanism with a planetary gear mechanism, achieving low vibration, a high reduction ratio, compact size and light weight, high rigidity, and high precision, contributing to improvements in industrial robot performance at the time.
