Servo Joint Modules for Humanoid & Quadruped Robots | MagicLab

MagicLab's self-developed servo joint modules integrate motors, reducers, encoders, drive electronics and control functions into compact motion units for humanoid robots, quadruped robots and collaborative robotic systems. The portfolio includes planetary, harmonic and linear modules covering different torque, speed, precision, size and force-output requirements. Selected models provide dual encoders, temperature feedback, CAN, EtherCAT or RS485 communication, and multiple control modes for torque, position, velocity, stiffness and damping. With compact structures, high torque density, responsive control and thermal-management design, the modules support robot legs, waists, arms, ankles, forearms and precision linear mechanisms. Module selection should be based on joint position, load, motion range, control protocol and operating environment.

Servo Joint Module Series & Engineering Advantages

Planetary Joint Modules

P110, P90N20, D90 and P60N30 provide a broad torque range for full-size and mid-size humanoid joints, quadruped legs and other high-load rotary mechanisms.

Harmonic Joint Modules

H60 and H70 combine compact dimensions, high positioning accuracy and strong bearing support for robot arms, waists, collaborative joints and precision manipulation.

Linear Joint Module

T28 integrates a ball screw, motor and dual encoders to deliver compact linear force for forearms, ankles and precision linear-motion applications.

Integrated Control & Feedback

Built-in drive electronics, encoder feedback, temperature monitoring and high-speed communication simplify wiring, improve controllability and accelerate robot-system integration.
