Overview

The eRob T-type joint module is a highly integrated all-in-one solution that combines eight core components: a servo motor, high-precision harmonic gear reducer, dual absolute encoders, servo drive, friction brake, temperature sensor, and virtual torque sensor. This innovative design eliminates the need for complex external component selection and integration, providing users with a plug-and-play power unit that significantly simplifies the robotics development process. It is an ideal choice for building high-performance collaborative and humanoid robots.
