MyActuator RH-25 Hollow Harmonic Actuator (EtherCAT & CAN, Dual Encoder)
MyActuator RH-25 Hollow Harmonic Actuator (EtherCAT & CAN, Dual Encoder)
🚀 Zero-backlash harmonic joint for high-precision robotics
🔍 Product Overview
The MyActuator RH-25 is an RH hollow-shaft harmonic joint actuator - a complete robot joint in a single unit that uses a harmonic (strain-wave) reducer for near-zero backlash and a hollow shaft that lets you route cabling straight through the joint - ideal where positional accuracy and clean wiring matter more than raw speed. It eliminates the need to engineer your own motor + gearbox + driver + encoder stack, which is why integrated smart actuators are the single most important building block of a modern humanoid robot.
