Product Description
The RI70-90 is an integrated hollow shaft harmonic drive robot joint actuator designed for robotic arms, humanoid robots, articulated joints, and advanced robotic motion systems.
It integrates a brushless motor, harmonic drive reducer, encoder feedback system, and hollow-shaft structure into a compact joint module, simplifying the integration of motor, reduction, and position feedback components in robotic joint designs.
The hollow-shaft architecture allows cables and wiring to be routed through the joint, making the RI70-90 particularly suitable for articulated robot arms and humanoid robot joints where compact mechanical integration and clean internal wiring are required.
The actuator supports multiple configurations, including CAN or EtherCAT communication, single or dual encoder feedback, and optional brake.

FAQ
What is the RI70-90 robot joint actuator?
The RI70-90 is an integrated robotic joint actuator combining a brushless motor, harmonic drive reducer, encoder feedback, and hollow-shaft structure in a compact joint module.
What is the advantage of a harmonic drive robot joint actuator?
Integrating the harmonic reduction mechanism directly into the joint reduces the need to separately assemble the motor, reducer, and feedback components, helping simplify robotic joint design.
Does the RI70-90 have a hollow shaft?
Yes. The hollow-shaft architecture provides internal space for routing cables and wiring through the robotic joint.
Does the RI70-90 support CAN communication?
Yes. CAN communication is available.
Is EtherCAT communication available?
Yes. EtherCAT is available as an alternative communication configuration.
Can I choose between single and dual encoders?
Yes. Single encoder and dual encoder configurations are available.
Is a brake available?
Yes. The RI70-90 is available with or without a brake depending on the required configuration.
Is the RI70-90 suitable for humanoid robots?
The integrated hollow-shaft and harmonic drive architecture makes it suitable for compatible humanoid robot joints, robotic arms, articulated robots, and other advanced robotic motion systems.
Can I order a different communication or encoder configuration?
Yes. CAN/EtherCAT, single/dual encoder, and brake configurations are available. Contact us before ordering if you require a configuration other than the standard listed version.
