The harmonic-reducer and robot‑components leg is genuine and partly in production, but it is not yet a broken‑out revenue line – the roughly 99% automotive‑bearing split absorbs it, so it is not yet a sized business. Across our filings the words ‘humanoid’ and ‘dexterous hand’ do not appear. We frame the robot side as industrial – high‑precision parts for core motion joints, smart‑terminal equipment, machine tools, medical devices and automation lines – and describe the field as still in its nascent stage. Whether the leg becomes a separate disclosed business remains an open question.
