Overview of PEEK Material Industry
Lightweight materials mainly correspond to the lightweight requirements of humanoid robots. Commonly used lightweight materials include magnesium alloys, aluminum alloys, carbon fiber composite materials, engineering plastics, etc. In the current context of "replacing steel with plastic" and "lightweighting", PEEK material, as a new polymer material, is gradually replacing metal materials in the mid to high end field with its excellent performance. PEEK (polyetheretherketone) material is a special engineering plastic at the top of the pyramid, with comprehensive properties at the top of the plastic pyramid. It has characteristics such as high temperature resistance, wear resistance, corrosion resistance, and self-lubricating, and its insulation and chemical resistance are superior to ordinary metals. The density is about half of aluminum alloy, which can achieve lightweight while maintaining high strength and rigidity.
Application of PEEK material in humanoid robots
According to publicly disclosed data comparison, the average weight of robots such as Tesla, Ubiquitous, and Zhiyuan is about 58kg. Among them, 1kg of pure PEEK material is used for gears and joints, and 8kgCF/PEEK is used for limbs. It is expected that a single robot will consume 6.6kg of PEEK. Joints and limbs: PEEK gears: applied to joints, limbs, and other parts of humanoid robots, providing stable transmission and support. PEEK bearings: applied to joints and other positions of humanoid robots, they have excellent wear resistance and self-lubricating properties, which can reduce friction and wear and improve the service life of robots. Body and limb skeleton: PEEK skeleton: used for the body and limbs of humanoid robots. Compared to metal materials, PEEK skeleton can reduce weight by 40% while maintaining sufficient strength and rigidity to meet the load and flexibility requirements of robots.

Mechanical arm components

Linear/rotary actuator is a device that converts rotary motion into linear motion or directly generates linear motion. Mainly used for joints such as wrists, elbows, knees, and ankles in humanoid robots, as well as components that require linear motion, such as arm extension and leg movement. Rotary actuator is a device that enables the joints of a robot to perform rotational motion. Mainly used for joints such as shoulders and hips in humanoid robots, as well as components that require rotational motion, such as arm rotation and head rotation. The commonality between linear and rotary actuators lies in the power source (frameless torque motor) and sensors (encoder, torque sensor), while the difference lies in the transmission mechanisms being planetary roller screws and reducers, respectively. The rotary actuator adopts a "motor+precision reducer" structure, while the linear actuator adopts a "motor+roller screw structure". The core components of linear/rotary actuators include frameless torque motors, roller screws, reducers, sensors, bearings, etc.
