Cycloidal vs. Harmonic: Which Robot Joint Is Better?

Cycloidal joint modules offer excellent shock resistance, high rigidity, high torque capacity and durability, making them ideal for humanoid robot legs, heavy-duty robotic arms, AGVs and other high-load applications.
Harmonic joint modules, on the other hand, are well known for high precision, low backlash and compact design, making them ideal for precision robotic applications.

The video shows a cycloidal shutdown module with a peak motor speed of 7643 RPM and a peak torque exceeding 590 N·m.

Models include Arc47/68/78/95/102;
operating voltage: 24~72V;
rated torque range: 3~180 Nm;
rated speed range: 100 RPM;

Harmonic Joint Module or Planetary Joint Module — Which One Is Better for Humanoid Robots? 🤖
When designing humanoid robots, choosing the right joint actuator is one of the most important decisions. Should we use harmonic joint modules or planetary joint modules?
The answer is: it depends on the application. In the future of humanoid robots, a hybrid solution combining both technologies may become the mainstream choice.
🔹 Harmonic Joint Modules
✅ High precision and extremely low backlash
✅ Compact size with high torque density
✅ Excellent position control and rigidity
They are ideal for:
Robotic arms
Shoulders, elbows, and wrists
Dexterous hands
Applications requiring high accuracy and smooth motion
🔹 Planetary Joint Modules
✅ Higher efficiency (90%+)
✅ Strong impact resistance
✅ Better for high-speed and continuous operation
✅ More cost-effective for mass production
They are ideal for:
Hip joints
Knee joints
Ankle joints
High-load and dynamic movements
For a humanoid robot, the best solution is usually not choosing only one technology:
Planetary joints for the lower body + Harmonic joints for the upper body can provide the perfect balance between:
⚡ Power
🎯 Precision
🛡️ Reliability
💰 Cost efficiency
