Track Opportunity | The Humanoid Robot Industry is Accelerating Implementation, High-End Joint Modules & Reducers are the Cornerstone for the Industry to Move towards Large-Scale Commercial Use
According to MIR forecasts, the market size of precision reducers for humanoid robots will reach the hundred-billion level by 2035. Dozens of joint modules all over the humanoid robot form the complete motion system of the robot, responsible for full-scenario actions such as walking, handling, grasping, twisting and flexible interaction, which directly determine the motion freedom, motion coordination and environment adaptation capability of the robot. As the core kernel of joint modules, the precision harmonic reducer is well-deserved the "heart of the joint". It undertakes the core functions of deceleration and torque increase, precise position control and power buffering, perfectly solves the inherent shortcoming of motors with high speed and low torque, and converts high-speed power into controllable, stable and strong driving force.
Under the strict requirements of humanoid robots for lightweight, high precision, long endurance and high flexibility, the reducer is no longer an ordinary transmission component, but the core lifeline that determines the robot's motion accuracy, load capacity, service life, safety and stability. The performance ceiling of the reducer is the motion ceiling of the humanoid robot; the integration level of the joint module directly determines the product experience and commercial implementation capability of the humanoid robot.
At present, the joint modules of humanoid robots generally have pain points such as obvious low-speed vibration, conflict between lightweight and high torque, excessive temperature rise, leading to the high-end supply field still being monopolized by overseas manufacturers dominated by Japanese enterprises, and the domestic supply chain is in urgent need of accelerated substitution.

Empowerment from Capital: Supported by diversified capital, to help build a leading enterprise of full-body rotary joints for humanoid robots
[Innoangel Fund] stated: Under the wave of humanoid robot industrialization, harmonic reducers, as the core components of light-load joints, are ushering in a huge incremental market. High-end products have been monopolized by Japanese enterprises for a long time, and local enterprises with independent high-end mass production capabilities have broad domestic substitution opportunities. We are optimistic about this company. Its harmonic reducer's comprehensive performance can match Japanese high-end products, with solid technical barriers. The company not only focuses on single reducer products, but also makes long-term layout of harmonic joint modules, extending downstream to fit the integrated procurement trend of complete machine manufacturers. Relying on excellent precision manufacturing skills, it is expected to deeply enter the humanoid robot supply chain, fully grasp the industry outbreak window, and its growth space is worth looking forward to.
[Wanwei Capital] stated: We are very optimistic about the differentiated transmission technology and delivery order potential of Hengxuan Robot, and will rely on the deep collaboration of algorithm ecological resources to empower the enterprise to expand the humanoid robot supply chain and accelerate the domestic substitution process of high-end reducers.
[Ninebot Capital] stated: The robot industry is gradually entering a new stage of competition for product definition and engineering capabilities, and core components will become the key foundation that determines the performance, cost and mass production efficiency of the complete machine. The core team of Hengxuan has been deeply engaged in the field of precision transmission for a long time, has R&D and industrialization experience in international leading precision transmission enterprises, has a deep understanding of the technology, products and manufacturing of harmonic reducers and robot joints, and has quickly realized product verification and customer introduction after starting the business. We are optimistic about Hengxuan's continuous accumulation in technology R&D, product definition and large-scale manufacturing, and look forward to the company growing into a leading enterprise with long-term competitiveness in the field of robot core components.
[DaoYi Capital] stated: At the current stage, the humanoid robot industry is at a critical stage from concept to mass production. As the core component of the complete machine, the joint module is the biggest production capacity bottleneck for the complete machine to move towards large-scale mass production. The founding team of the company takes the Japanese precision transmission system as the technical source, has complete experience from forward R&D of reducers, product definition of modules to industrial implementation, and is a scarce core supplier in China that has both the self-manufacturing capability of underlying components and the understanding of complete machine applications, forming a non-replicable core barrier and differentiated advantage. We are highly optimistic that the company will become the definer of the standard and the core platform for humanoid robot rotary joints at this industrial inflection point.
[Shenzhen Guarantee Venture Capital] stated: The core investment value of Hengxuan Technology lies in its deep technical moat. The team is derived from Japan's top precision transmission system, has mastered the forward design capability of harmonic and cycloidal reducers, and has achieved breakthroughs in key indicators such as torque density and impact resistance. This "root technology" capability of self-developing and self-manufacturing underlying core components enables its products to have both high performance and low cost advantages, builds an extremely high industry entry threshold, and is a platform-type enterprise scarce in the robot industry chain with underlying technology innovation and definition capabilities.
[Shenzhen Angel FOF] stated: Physical AI represented by embodied intelligent robots will bring a rotary joint market dozens of times larger than that of industrial robots. Under new scenarios, robots' requirements for lightweight, low vibration, load adaptability and other aspects are increasingly prominent. The main reason why we are optimistic about the Hengxuan project is that the team has forward-looking experience of Japanese precision reducer manufacturers on the R&D side; has a mature system on the production side; and has forward-looking insight into the industry evolution on the market side. We believe that Hengxuan is expected to seize the opportunity of physical AI and become an international first-class supplier of core rotary joints.
