In the field of embodied intelligence, force sensors serve as the “tactile nerves” of humanoid robots. From gentle assistance in daily services and object picking to precise industrial assembly and medical auxiliary operations, the sensitivity and reliability of force sensors directly determine the robots’ task adaptability and practical value. In recent years, several domestic companies have made continuous breakthroughs in the field of humanoid robot force sensors, breaking international monopolies while forming an industrial pattern with distinct technical characteristics and market advantages.
Blue Dot Touch (Beijing) Technology Co., Ltd. is a national high-tech enterprise focused on the research and application of cutting-edge force control technology for intelligent robots. As a professional force control solution provider, the company offers one-stop services including robot force sensor hardware, force control algorithms, and industry process algorithms.

The performance of Blue Dot Touch’s products has reached an internationally leading level, with an accuracy of up to 0.1% FS and a response frequency exceeding 10 kHz, and the core components are 100% domestically produced. In terms of market performance, the company has achieved a domestic market share of over 70% in the field of six-dimensional force sensors for humanoid robots, with even greater advantages in the robot joint force sensor business. In the first half of 2025, the shipment volume exceeded 70,000 units, accounting for over 95% of the total domestic shipments. Currently, Blue Dot Touch has become a core supplier for almost all leading companies in the industry, including Zhiyuan Robotics, Xiaomi Robotics, and UBTECH.
Ningbo Keli Sensor Technology Co., Ltd. was established in 1995 and mainly develops and produces various sensors, industrial IoT systems, and multi-scenario application solutions. It is a national-level manufacturing single-item champion demonstration enterprise, a national-level enterprise technology center, and a national manufacturing “double innovation” platform.
Keli Sensor has completed strategic investments in humanoid robot companies such as Kepler Humanoid Robotics, tactile sensor companies like Tashan Technology, and leading inertial measurement unit (IMU) companies like Wuxi Beimi Sensor. Through these investments, Keli Sensor has initially built a robot sensing solution capability centered on six-dimensional force/moment sensors, integrating tactile, IMU, and other multi-modal perception capabilities. The company has currently provided samples to over 50 domestic humanoid robot, collaborative robot, and industrial robot companies, with products covering key components such as six-dimensional force/moment sensors and joint torque sensors. Nearly a thousand units of six-dimensional force sensors have been shipped, and some customers have moved from sample verification to small batch orders, with product performance and reliability recognized by the market.

The sensors required for humanoid robot wrists and ankles need to have a small diameter, but the robots themselves are heavy, and during movements such as jumping and running, they can experience multiple overloads. To address the characteristics of humanoid robots, Kunwei Technology has developed the HRS series six-dimensional force sensors with a small size and large range, achieving an accuracy better than 0.1% FS and a precision better than 0.3% FS. The company has now entered the supply chains of leading brands such as Zhiyuan, UBTECH, Xiaomi, Galaxy General, and Fourier, with the first domestically mass-produced humanoid robot product using its six-dimensional force sensors.
Haibosen Technology (Shenzhen) Co., Ltd. is a national high-tech enterprise and a specialized and innovative enterprise in Shenzhen, mainly engaged in self-developed products, including 3D flash measurement sensors, 3D line spectral confocal sensors, point spectral confocal sensors, laser tool setting instruments, ultra-high-speed industrial cameras, six-dimensional force sensors, and laser needle sensors.
Haibosen’s self-developed six-dimensional force sensors have been supplied in bulk to over 20 leading robot companies, providing gram-level force control accuracy for humanoid robots, collaborative robots, and high-end industrial scenarios, enhancing the robots’ perception capabilities. Against the backdrop of the robot industry relying on imported sensors, Haibosen leverages the advantages of the Shenzhen supply chain, achieving 80% localization of components and compressing the delivery cycle to as fast as one week, thus improving the responsiveness of domestic production.
From technological breakthroughs to market implementation, domestic force sensor companies are building a complete industrial ecosystem with differentiated advantages, continuously leading in the localization rate of core components, performance indicators, and delivery efficiency. As the humanoid robot industry enters a critical stage of large-scale production, these domestic forces will continue to use precise perception technology as a foundation to break technical barriers, reduce application costs, and provide core support for the widespread adoption of robots in more scenarios, promoting the leap from following to leading in the global humanoid robot industry.
