Bionic muscle technology has broken through the flexibility bottleneck of robots, expanding the application scenarios for humanoid robots.
With the rapid iteration of the humanoid robot, flexible intelligent manufacturing, and rehabilitation medical equipment industries, the limitations of traditional rigid driving components have become increasingly prominent. The motors, cylinders, and hydraulic drive modules widely used in the industry have problems such as heavy weight, high rigidity, poor human-robot interaction safety, and poor environmental adaptability, making it difficult to meet the application requirements of lightweight, flexible, and highly simulated robots. As a new flexible drive technology that benchmarks the mechanical properties of human muscles, bionic muscle has become the core track to break the bottleneck of humanoid robot implementation. The bionic muscle project plans to rely on independent flexible materials and bionic drive algorithms to specifically solve the industry pain points of traditional robots such as large rigid impact, high energy consumption, unnatural movement, and limited adaptation scenarios, and it is expected to expand the commercial implementation boundary of industrial collaboration, medical rehabilitation, and home service robots in the future.
Industry pain points are prominent, and traditional drive solutions restrict large-scale industrial implementation
At present, the global bionic robot industry has entered a stage of rapid commercialization. In 2025, the global bionic robot market size exceeded 8.74 billion US dollars, maintaining a rapid growth rate of over 30%. Among them, humanoid robots and flexible collaborative robots have become the focus of capital and industrial layout. However, the technical shortcomings at the drive end have always been the core pain point restricting the large-scale popularization of the industry.
At the technical level, mainstream solutions such as traditional pneumatic muscles, shape memory alloys, and electroactive polymers all have obvious defects. The fatigue life of pneumatic muscles can only reach the order of ten thousand times, which is far lower than the durability requirement of more than 100,000 times for industrial applications. In addition, the motion hysteresis effect is obvious and the control error is large, resulting in insufficient accuracy of robot movements. Shape memory alloy drives have slow response speed, high energy consumption loss, and are prone to accumulated heat during long-term operation, which cannot meet the requirements of high-frequency continuous operation. At the same time, domestic high-end bionic drive materials have long relied on imports, with a high import dependence of core materials. Overseas patent barriers and supply chain monopolies have significantly increased the hardware procurement costs of domestic robot enterprises.
At the application level, traditional rigid-drive robots cannot achieve flexible buffering, and rigid impact is easy to occur during human-robot contact, which poses great safety hazards and is difficult to adapt to close-range interaction scenarios such as home services, elderly care rehabilitation, and close-range industrial collaboration. At the same time, most commercial robot equipment is bulky, high in energy consumption, insufficient in lightweight and bionic degree, and the fluency and naturalness of movements are far less than the movement effect of human limbs, which greatly limits the scene penetration ability of humanoid robots. On the whole, the backwardness of drive technology has become a key bottleneck restricting domestic humanoid robots from moving from prototype R&D to large-scale commercialization.
Plan to develop self-developed bionic muscle technology and deploy core solutions for flexible drives
The bionic muscle project aims at the flexible robot drive track to carry out preliminary planning, and plans to carry out technical research in three directions: bionic mechanics design, modified flexible composite materials, and precise drive control algorithms, with the goal of building a highly adaptable, highly durable, low-energy-consumption bionic muscle drive system, realizing the replacement of some traditional rigid drive components, and making up for the existing technical shortcomings in the industry.
According to the project plan, the material R&D link will try to break through the barriers of imported materials, develop modified nano-composite flexible materials, iteratively optimize the core parameters of materials such as stretching, rebound, and fatigue resistance, aiming to improve the common industry problems of traditional flexible components such as easy aging, easy damage, and insufficient durability, reduce the equipment's dependence on high-voltage power supply and complex heat dissipation systems, streamline the overall structure of the robot, and achieve energy consumption reduction.
In terms of structure and algorithm, the project plans to replicate the movement logic of human muscle stretching, contraction and buffering, design an integrated bionic drive structure, and get rid of the constraints of traditional bulky transmission modules. Simultaneously develop supporting dynamic drive control algorithms, aiming to achieve millisecond-level response, accurately adjust the contraction amplitude, stretching force and movement frequency, improve the hysteresis error of traditional drive solutions, so that the robot's limb movements can achieve simulated, soft and stable output effects. Relying on the flexible adaptive buffering design, automatic force unloading is realized in the state of human-robot contact, the safety risk caused by rigid impact is avoided, and the safety of human-robot interaction is improved.
Compared with traditional drive solutions, the planned bionic muscle system will focus on the characteristics of light weight, low power consumption, high flexibility and high adaptability. It is compatible with terminal equipment such as humanoid robots, flexible manipulators, rehabilitation exoskeletons, and bionic educational robots, with strong expansion space.
Preset diversified business models to target the incremental market of flexible robots
The bionic muscle project carries out preliminary planning for the B-end industrial market, and plans to build a business model of "hardware module sales + technology licensing + customized solution development", with potential target customers covering robot manufacturers, intelligent equipment enterprises, and medical equipment R&D institutions.
In the project plan, the standardized bionic muscle drive modules can be supplied to small and medium-sized robot manufacturers, providing domestic flexible drive accessories to help downstream enterprises reduce the cost of complete machine R&D and production, and complete the flexible upgrading of products. For large equipment enterprises and leading robot brands, customized structure design, algorithm adaptation, and drive solution development services can be provided, and customized systems can be output according to the needs of different scenarios such as industrial collaboration, medical rehabilitation, and special operations. At the same time, the project plans to explore the technology licensing mode, carry out joint R&D with enterprises in the industrial chain, and promote technology implementation.
From the perspective of market space, the global artificial muscle industry maintains a steady and rapid growth. The market size exceeded 300 million US dollars in 2025, and it is expected to exceed 800 million US dollars in 2032, with a compound annual growth rate of about 15%. With the acceleration of the commercialization of humanoid robots, the expansion of the elderly care rehabilitation industry, and the popularization of flexible intelligent manufacturing, the potential market demand for bionic flexible drive components will continue to be released. At this stage, the project is still in the stage of creative and preliminary scheme planning, and no physical prototype has been produced. A series of work such as scheme demonstration, prototype R&D, and performance test will be promoted in the follow-up, and external docking and pilot implementation will be carried out after the technology is mature.
In the future, the bionic muscle project plans to continue to deeply cultivate the R&D of flexible drive technology, continuously iterate material properties, explore cost reduction paths, hoping to fill part of the domestic technical gaps in high-end bionic drives and help the domestic humanoid robot industry move forward.
