Building Humanoid Robots with Robot Joint Actuators: A Systematic Solution from Prototype to Mass Production

Designing a compact, high-torque robot joint requires more than selecting a motor or harmonic reducer—it requires optimizing the entire actuator system around the robot’s mechanical, motion, electrical, and integration requirements. This article presents a practical engineering approach covering actuator selection, harmonic transmission, torque density, encoder and brake...

This article provides an in-depth analysis of the key technologies that determine RV reducer performance, focusing on cycloidal gear profile modification, precision manufacturing, and long-term accuracy retention. It explains how optimized tooth profile modification affects backlash, transmission accuracy, load capacity, noise, and service life, while high-precision manu...

Choosing a planetary gearbox should start with the application problem, not simply the highest torque or lowest backlash specification. Industrial robots require low backlash and high torsional rigidity for precise dynamic motion, CNC machines need stable accuracy and thermal performance during continuous operation, while AGVs and AMRs prioritize efficiency, lightweight ...
