What happened: Force-sensor maker Link-Touch said it closed a Series C+ round of more than RMB 100 million, with investors including CATL-linked Puquan Capital and strategic backers like Agibot and Galbot.

Why it matters: Humanoid robots can see and plan, but they still struggle with reliable contact-rich manipulation, and Link-Touch argues force sensing and control is the missing layer between “the arm moved” and “the task worked.”

Wider context: The company claims performance of 0.1% full-scale accuracy, response above 10 kHz, and 500% overload resistance, and says it has volume orders from a roster of Chinese robotics and auto-adjacent firms, as sensor supply becomes a battleground for scaling humanoids.

Background: KrASIA notes CATL has been investing across the embodied-robotics supply chain, and cites market-share estimates that put Link-Touch at roughly 62% of China’s humanoid six-axis force-sensor market in 2024, with projections rising in 2025.

Droid Brief Take: This is the part of humanoid robotics that rarely makes the sizzle reels: precision manipulation is not a motivational speech problem, it is a force-control problem. Money flowing into sensors is an admission that “just add a bigger model” does not magically fix contact physics.

Key Takeaways:

• Funding Round: Link-Touch said the Series C+ raise exceeded RMB 100 million and included Puquan Capital (affiliated with CATL) plus strategic investors and customers such as Agibot and Galbot.
• Component Metrics: The company reported 0.1% full-scale accuracy, response above 10 kHz, and 500% overload resistance for its force-sensing products, positioning them for fast, contact-rich tasks.
• Scaling Pressure: The article ties rising humanoid shipments and supply-chain buildout to demand for force control, noting force data is harder to simulate and often needs real-robot operation to train and validate manipulation.
