36Kr learned that BluePoint Touch (Beijing) Technology Co., Ltd. (hereinafter referred to as "BluePoint Touch") recently announced the completion of a nearly 100 million yuan Series B financing round. This round of financing was jointly invested by GF Xinde, Fosun Capital, Hefei Innovation Investment, and Huacang Capital. The funds will be used for product R & D investment, overseas market expansion, team recruitment, and other aspects.
Founded in 2019, "BluePoint Touch" is a national high - tech enterprise focusing on the R & D and application of intelligent robot force control technology. The core team mainly comes from scientific research institutions such as the University of Science and Technology of China, China Aerospace Science and Technology Corporation, and the Chinese Academy of Sciences. Professor Wang Tianmiao, the honorary director of the Robotics Institute of Beihang University, serves as a director of the company. Currently, it has formed multiple product series, including six - axis force sensors for humanoid robots, general six - axis force sensors, joint torque sensors, and tension - compression sensors.
The force sensor products of "BluePoint Touch" cover both the traditional industrial robot field and the emerging humanoid robot field. In the field of industrial robots, "BluePoint Touch" focuses on areas such as grinding, assembly, medical surgical robots, and welding. Its products have been applied in industries such as medical, aerospace, 3C electronics, and automotive. In the field of humanoid robots, "BluePoint Touch" has established partnerships with leading enterprises in the industry, such as Zhipu Robotics, Xiaomi Robotics, Qianxun Intelligent Robotics, Ubtech, and Zhongqing Robotics, and has become their bulk supplier.
I. Promote the large - scale application of force sensors and cost reduction with platform - type technical capabilities
The six - axis force sensor was first systematically applied in the aerospace field to measure the aerodynamic characteristics of aircraft during wind tunnel tests and flight. In an embodied intelligent system, the force sensor is equivalent to the core force sense organ of the robot. Through the strain or piezoelectric effect, it converts the environmental forces acting on the end of the robotic arm, joints, or soles into electrical signals and feeds them back to the control system in real - time, enabling the robot to achieve functions such as precise operation control, collision protection, and adaptive motion control.
For a long time, international manufacturers represented by ATI have occupied the high - end force sensor market with their first - mover advantage. However, Liu Wuyue, the founder of "BluePoint Touch", believes that domestic force sensors have deeper technological accumulations. "China has more than 70 years of experience in researching six - axis force sensors in the aerospace field. Our core team comes from the aerospace field, which means we are standing on the shoulders of giants. Therefore, in terms of performance such as crosstalk and sensitivity, our current level is actually better than foreign brands." The real challenge for domestic emerging enterprises lies in how to transform the "cost - regardless" technical system in the aerospace field into an industrially replicable solution and solve the cost problem.
It is reported that "BluePoint Touch" has made a series of adjustments in cost control and technical solutions, achieving better cost - performance while maintaining high performance. "Firstly, through technical means, we have improved the overall iteration of hardware circuits, structures, and production processes by improving the technical solutions. Secondly, we have improved production efficiency and ensured a high yield rate through the improvement of automated production processes. Thirdly, through the scale effect, after achieving large - scale production, we have further reduced costs and improved production quality through management means and supply - chain management." Liu Wuyue summarized.
In terms of specific product performance indicators, "BluePoint Touch" has made significant progress in three aspects: In terms of accuracy, it generally achieves 0.3% FS, and the six - axis force sensor for humanoid robots has a high accuracy of 0.1% FS; In terms of response speed, on some joints, the maximum response frequency reaches 10kHz, which means it can respond to a data point every 0.1ms; In terms of integration, the weight of the sensor has been reduced by more than 80% and the volume by more than 90% compared to the original, allowing partners to implant the force sensing function almost "unconsciously".

Behind the performance improvement is the underlying platform - type technical capability. The technical platform of "BluePoint Touch" includes four core technologies: The first is the iterative design of high - performance elastomers, which achieves high performance, high structural strength, low crosstalk, and high overload capacity through a delicate structure; The second is the embedded hardware circuit, whose core is to obtain the entire underlying strain data under low - noise and high - bandwidth conditions; The third is the force control algorithm, which emphasizes efficient and high - precision decoupling, quickly and accurately decoupling the data from hundreds of internal sensitive points into six - axis information data; The fourth is the high - precision six - axis synchronous calibration technology, which uses technologies such as optical guidance and floating loads, as well as the comprehensive technology of six - axis synchronous loading, to form a high - precision calibration system to ensure overall accuracy.
Relying on the platform - type technical capability, "BluePoint Touch" can reduce the customer demand response cycle from 6 - 8 weeks for customized products to 3 - 4 weeks. In the industrial environment where embodied intelligent technology is accelerating its iteration, the marketization cycle of complete machine products has generally been compressed to 6 - 8 months. The ability to compress time has also become an important indicator for measuring the competitiveness of technology - based suppliers.
II. The growth of the embodied intelligent industry exceeds expectations, accelerating domestic market penetration and overseas layout
In Liu Wuyue's view, the embodied intelligent industry has developed rapidly in the past two years. On the one hand, in the field of industrial robots, the growth rate of collaborative robots is very fast. Two years ago, orders of dozens of units were considered large customers, but now orders in the thousands have emerged in the industry. On the other hand, humanoid robots began to develop significantly in the second half of 2023. According to an IDC report, the commercial sales volume of humanoid robots in China in 2024 was about 2,000 units, exceeding industry expectations. Liu Wuyue estimates that according to the current trend, the shipment volume of humanoid robots in 2025 may reach 5,000 to 10,000 units.
Meanwhile, as the embodied intelligent industry accelerates its practical application, the importance of force sensors has gradually become prominent. "When robots truly interact in practical scenarios, it is difficult to achieve high - precision requirements through visual positioning alone in any contact scenario. At this time, a human - like operation mode is typically needed, that is, rough positioning by vision and fine operation by force sense." Liu Wuyue observed that the industry began to install six - axis force sensors at the end of the robot last year, and this year, it started to install joint force sensors on each joint. "Because the installation speed of six - axis force sensors is the fastest, while joint force sensors have better response speed." According to industry statistics, humanoid robots generally require four six - axis force sensors for wrists and ankles and 28 joint torque sensors, which account for about 15% of the BOM cost of the entire humanoid robot in mass - production.
For the different needs and product characteristics of the humanoid robot and industrial robot sectors, "BluePoint Touch" has launched corresponding product series. For humanoid robots, it has developed the LA and LC series products, including six - axis force and joint torque sensors for humanoid robots; for the traditional industrial field, it has launched the LB, LD, and LE series, which are general six - axis force sensors, joint torque sensors, and tension - compression sensors respectively.

Public information shows that "BluePoint Touch" has formed a strong advantage in large - scale production. In 2024, its market share in the six - axis force sensor field for humanoid robots exceeded 70%. In the first half of 2025, the shipment volume of six - axis force sensors to several single customers reached thousands of units; In terms of robot joint force sensors, "BluePoint Touch" shipped nearly 50,000 sets in 2024 and more than 70,000 sets in the first half of 2025, accounting for more than 95% of the total domestic shipment volume.
"Force sensors are essentially components, and the development rules of components must be respected. In the early stage, we quickly expanded the market with technological advantages, but ultimately, long - term sustainable development must be achieved through large - scale production. The company has timely transformed its technological advantages into scale advantages and market share, and at the same time, formed comprehensive advantages in service, quality, and cost in reverse." Liu Wuyue introduced that the annual sales revenue of "BluePoint Touch" has doubled for three consecutive years, and it has achieved positive cash flow.
After this round of financing, "BluePoint Touch" will further increase R & D investment and expand its team, and develop more sensor products in niche fields to meet the requirements of humanoid robots for small size, high precision, and high bandwidth. In the market, it will expand the business channels of core customers with comprehensive technological advantages and develop overseas customers in the European and American markets.
