Product Overview

The eRob70I is a compact 70 mm diameter I-type integrated robot joint module delivering up to 70 Nm peak momentary torque from a 100 W motor. Combining all eight core subsystems in a single 0.77 kg plug-and-play unit, it dramatically reduces mechanical and electrical development complexity for collaborative and humanoid robot builders.

The eRob70I is a fully integrated rotary actuator combining servo motor, harmonic gear reducer, encoders, servo electronics, and compact mechanical packaging in a single assembly.
