What Is the Difference Between Different Sizes of Harmonic Joint Modules?

Different sizes of harmonic joint modules generally offer different torque capacities, mechanical dimensions, weights, and installation interfaces. Larger modules may provide higher torque capacity, making them suitable for joints with greater load requirements. Smaller modules are often considered for applications with stricter space and weight limitations.

However, physical size alone does not determine performance. Engineers should compare rated torque, peak torque, output speed, reduction ratio, positioning accuracy, and overall weight when evaluating different models.

For humanoid robots, hip and knee joints may require different specifications from wrist and elbow joints. The most suitable size should be determined by the actual load profile and available installation space rather than selecting the largest available model.
