Xin Fenglong Launches Four Series of Robot Joint Products, Promoting Localization of Core Components
Relying on UBTECH's embodied intelligence technology and Fenglong Co., Ltd.'s precision manufacturing capabilities, Xin Fenglong has launched four series of products: planetary, harmonic, and linear joint modules, as well as miniature servos for bionic human faces. The planetary joint module has a peak torque of up to 300Nm and a torque density of up to 200Nm/kg; the harmonic joint module has an absolute position accuracy of ±0.2°; the linear joint module has a peak push-pull force of up to 100N and a stroke of 20mm. The miniature servo for bionic human faces has already achieved mass production, with dimensions of 23mm*14mm*28.7mm and a weight of less than 40g; at the same output torque, the length dimension is reduced by 18%.

Planetary Joint Module Focused on high torque density and excellent dynamic response capability, with peak torque up to 300Nm, torque density up to 200Nm/kg, support for hollow wiring, absolute position accuracy ±0.7°, and relative position accuracy ±0.5°, suitable for highly dynamic commercial service humanoid robots, mobile robots, and others.
Harmonic Joint Module Used in scenarios requiring precise and smooth motion control, with absolute position accuracy ±0.2°, relative position accuracy ±0.05°, reduction ratio up to 161, and multiple models supporting hollow structures; it can be used not only in light-load precision humanoid robots but also to meet the requirements of industrial scenarios for high-precision compliant motion.
Linear Joint Module Deeply integrates the screw, drive, and encoder to create the robot's "linear muscle," with peak push-pull force up to 100N, thrust density up to 1785.71N/kg, stroke 20mm, and absolute position accuracy ±0.05mm; it can perform high-precision linear reciprocating motion and is used in bionic telescopic structures such as dexterous hands and dexterous arms.
Bionic Humanoid Facial Micro Servo Designed for the narrow space of the face, it has the core advantages of smaller size, greater torque, higher integration, and lighter weight. The product has achieved mass production, effectively resolving the contradiction between space and performance in facial expression actuation for bionic robots. Product dimensions are 23mm*14mm*28.7mm, weight less than 40g, maximum torque 6kgf?cm, equipped with dual absolute encoders, repeat positioning accuracy 0.5°, and support for 360° rotation. Compared with similar products on the market, under the same output torque conditions, the length dimension is reduced by 18% and the height dimension by 4%, further compressing the overall size and weight for easier installation into the compact head structure of bionic robots. The motor adopts a 12mm-diameter PMDC brushless solution, is configured with CAN high-speed communication, has a data refresh rate ≥100Hz, supports online firmware upgrades, and integrates multiple protections against overcurrent, overvoltage, undervoltage, and overheating.
With the rapid development of the humanoid robot industry, industry demand continues to grow for domestic integrated joints with high integration, high reliability, and a complete specification spectrum. In the future, New Fenglong will continue to refine product performance, advance technology iteration and product engineering optimization, deeply collaborate with upstream and downstream partners, and provide abundant domestic component options for the humanoid robot industry.
