Torque Density in Harmonic Joint Modules: A Key Parameter for Lightweight and Space-Constrained Robotic Arms

Torque density shows how much output torque a robotic joint can deliver within a limited weight and size.

This article explains why torque density is an important parameter when selecting harmonic joint modules for robotic arms. Instead of focusing only on rated torque, engineers should also consider actuator mass, volume, precision, thermal performance, dynamic performance, and installation constraints. A high-torque-density harmonic joint module can provide sufficient torque in a compact and lightweight package, making it valuable for humanoid robots, cobots, medical robots, mobile manipulators, aerospace systems, inspection robots, and other space- or weight-constrained applications.

Harmonic Rotary Actuator: Built-In Driver vs. External Driver — Which Is Right for Your Application?

A built-in or external driver should be selected based on the actuator’s space, wiring, thermal, control, and maintenance requirements.

Harmonic Rotary Actuators can use either built-in or external drivers, with each configuration suited to different machine architectures. Built-in drivers are useful for compact robotic joints, humanoid robots, collaborative robots, and applications where space and wiring are major constraints, while external drivers offer greater flexibility for CNC systems, semiconduct...
