Friends, do you remember the humanoid robot half marathon a few days ago? Those “steel athletes” that fell and got back up resemble our mindset when trading stocks, with ups and downs yet always moving forward.But did you notice that the seven teams that completed the race all share a common secret: the breakthrough in tactile sensors? Why are tactile sensors considered the “lifeline” of humanoid robots? What is the ultimate goal of humanoid robots?It is not about how fast they can run, but about being “precise” like humans.Whether it’s screwing in a bolt, holding a coffee cup, or navigating complex terrains, the sensitivity of tactile sensors directly determines whether a robot can perform high-precision actions. Currently, the industry faces a critical issue: 90% of the global tactile sensor market is still dominated by giants from Japan and Germany, making domestic alternatives urgent. Take Tesla as an example; its third-generation dexterous hand is equipped with tactile sensors that can handle a single-finger load of 3kg, but the cost is as high as several thousand dollars.Meanwhile, domestic manufacturers are breaking barriers with a “technology + supply chain” approach. XXXX’s electromagnetic tactile sensors (already in mass production) have improved resolution to 0.1g level by optimizing magnetic field distribution; XXXX’s capacitive solution utilizes flexible materials to achieve a fusion of temperature, pressure, and humidity in three modalities.Although these two companies have different technical routes, they both target the cost reduction needs of OEMs like Tesla and Xiaomi. Who are the true “invisible champions”? Five A-share targets: from “technological positioning” to “capacity competition” 1. Riying Electronics:Leveraging university resources to create differentiated technology paths, the market penetration of robotic vacuum cleaners is less than 5%, but the growth rate is expected to exceed 300% by 2025. 2. Orbbec:Ranked third globally in 3D vision sensor market share, the service robot business is expected to see a 120% year-on-year revenue increase in 2024, with a valuation of only 20 times, providing a high safety margin. 3. Lingyun Co., Ltd:The domestic market share of six-dimensional force sensors is less than 10%, but the company has secured top client orders in the industrial robot sector thanks to its accumulated technology in automotive pressure sensors. 4. XXXX:The only domestic company to achieve mass delivery of electromagnetic tactile sensors, with orders for the Tesla Model Y project already locked in for ramp-up in 2026. 5. XXXX:Leading the industry by 1-2 years in flexible capacitive tactile sensor technology, Xiaomi’s automotive smart cockpit is expected to become the first large-scale application scenario. Investment Logic: From “concept speculation” to “order fulfillment” Many people are focused on the Tesla supply chain, forgetting that the real breakthrough for humanoid robots lies in the domestic market.According to estimates by CITIC Securities, the domestic shipment of humanoid robots will exceed 100,000 units by 2025, with the tactile sensor market alone reaching 2 billion yuan. Companies like XXXX and XXXX have already entered the stage of actual orders, with XXXX’s tactile sensor revenue expected to increase by 200% year-on-year in 2024, and XXXX’s related product gross margin exceeding 70%. More critically, the industry chain is moving from the laboratory to the production line. Zhejiang Rongtai’s micro screw production line has reached a monthly capacity of 10,000 sets, and Mingzhi Electric’s hollow cup motors have passed certification from Yushu Technology. Once the capacity bottleneck on the hardware side is broken, the speed of software algorithm iteration will determine who can seize the opportunity. Remember, humanoid robots are not a science fiction novel, but an industrial revolution that is happening now.In this “hard battle” for tactile sensors, whoever can secure mass production orders before Q3 2025 will be able to earn the first pot of gold from a decade of dividends.Now is the golden window to “stand on the shoulders of giants and pick up chips”.
