This article explains how an application-driven engineering approach can solve compact robot joint actuator challenges by optimizing transmission, motor, sensing, cable routing, and mechanical integration as one complete solution.
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...
