In 2025, the humanoid robot industry officially entered the first year of mass production. Domestic and foreign manufacturers have increased their investment in research and development to accelerate the commercialization of humanoid robots. According to data, the market size of humanoid robots continues to grow, and domestic and foreign manufacturers are actively deploying to accelerate technological innovation and commercial applications. However, despite significant technological progress, humanoid robots still face many challenges, among which weight reduction and cost issues are particularly prominent. First, weight reduction: the key to improving performance. Weight reduction is the key to improving the motion performance, extending the battery life, and enhancing flexibility and operability of humanoid robots. Lightweight humanoid robots can complete various actions faster and improve work efficiency. At the same time, reducing weight helps to reduce the inertial force of the robot during movement and reduce the burden on the drive system, thereby extending the battery life. However, humanoid robots currently still have bottlenecks in material selection, structural design, etc., resulting in a large overall weight, which affects their performance and application range. Second, cost: a problem that restricts commercialization. The cost structure of humanoid robots is complex, mainly including powertrain systems, intelligent sensing systems, and structural parts. Among them, the powertrain system and intelligent sensing system account for a large proportion of the cost. In addition, the use of high-performance materials also increases the manufacturing cost of robots. Therefore, how to reduce costs while ensuring performance has become an urgent problem to be solved in the humanoid robot industry. In response to the weight reduction and cost issues faced by humanoid robots, the application of lightweight material PEEK provides an effective solution. 01. Significant weight reduction effect PEEK material has excellent mechanical properties, heat resistance and chemical stability, and has a low density. Compared with traditional metal materials, PEEK can significantly reduce the overall weight of humanoid robots, improve maneuverability and flexibility, reduce energy consumption, and extend battery life. 02. Cost optimization potential By optimizing the production process and improving the utilization rate of materials, the cost of using PEEK in humanoid robots can be effectively reduced. With the continuous advancement of PEEK material production technology and the expansion of the market scale, its cost is expected to be further reduced. At the same time, the lightweight characteristics of PEEK materials help reduce the energy consumption and maintenance costs of robots, which has the effect of reducing total costs in the long run. Based on the weight reduction effect and cost optimization characteristics, the main components of PEEK used in humanoid robots include the following four aspects: 1. Structural parts Limb bones and joints: PEEK has high specific strength and low density, which effectively reduces the weight of the robot while maintaining structural strength and stability. Robotic arm: PEEK composite carbon fiber material can be used in the robotic arm to further improve the safety and movement efficiency of the robot. 2. Transmission and connection parts Gears and chains: PEEK gears are suitable for transmission systems due to their wear resistance and low noise characteristics. Bearings and bolts: PEEK bearings are used in joints to effectively reduce friction and noise. 3. Protection and housing Sensor and actuator housing: PEEK is widely used in the manufacture of sensor and actuator housings due to its lightness, corrosion resistance and easy processing. These housings effectively protect precision electronic components from interference and damage from the external environment. Decorative parts: Plastic housings not only have protective functions, but also take into account the needs of appearance design. Through processes such as injection molding, housings of various shapes and rich colors can be manufactured to enhance the overall aesthetics of the robot. 4. Energy and energy storage components Battery housings and insulating components: PEEK’s insulation and high temperature resistance make it an ideal choice for energy modules. The battery housing is made of plastic, which can effectively isolate the high-voltage circuit inside the battery and prevent safety hazards such as short circuits and electric shocks. At the same time, the high temperature resistance of plastic can also ensure the stable operation of the battery in a high temperature environment.
