In our 183-page annual, 液压 appears 311 times, 丝杠 3 times, 人形 zero. 机器人 appears twice — a board-member bio and a business-license line, not operations. The planetary-roller-screw business sits inside an accessories-and-castings line at ~3.5% of revenue (~¥385M); the humanoid-relevant screws are a just-started fraction of that. No humanoid end-market is named. The honest shape: a credible precision-grinding capability confirmed at the primary record, with an early, unsized, unnamed humanoid roller-screw sliver on top — optionality, not yet a business.
