Cobots Robot Arm T type Harmonic Rotary Joint Module

●  Introduction

The T-type harmonic joint module is a highly integrated robotic joint unit that combines a harmonic reducer, torque motor, precision sensors, brake, and driver. It is called “T-type” because the output flange is perpendicular to the motor shaft, forming a T-shaped layout ideal for rotary robot joints.
Designed for collaborative robots, the module simplifies development by integrating key components into one compact, plug-and-play unit. This greatly shortens the development cycle, lowers costs, and makes building a robotic arm almost as easy as assembling LEGO blocks. Its high integration also improves maintenance efficiency and expands the applicability of robotic-arm technology.

Features

Compact T-shaped structure

The T-shaped design enables efficient integration within limited space, making it easy to install at the end of a robotic arm or between arm segments. It greatly simplifies the mechanical design of joints for robots such as collaborative robots and multi-axis manipulators, thereby reducing the overall development cycle.


High integration and protection
The module’s housing is typically streamlined and may offer environmental protection up to IP54. It often adopts a hollow-shaft cavity to accommodate electrical wiring, achieving clean and organized cable management.


High-precision control
With the combination of a harmonic reducer (transmission accuracy within 0.005°) and high-precision sensors, the module provides exceptionally accurate motion control.


High torque output
The harmonic reducer converts the motor’s high rotational speed into large torque output, meeting the load-bearing requirements of robotic applications.


Fast response and high reliability
The high level of integration reduces mechanical transmission components, improving system responsiveness and reliability. It is plug-and-play and requires minimal maintenance.


Force-position hybrid control capability
The module supports hybrid force/position closed-loop control, offering torque feedback with millisecond-level latency and a high signal-to-noise ratio, making it suitable for complex force-control scenarios.
