Product Features

Zero backlash l High repeatability

RGD series uses directly electric rotating machinery to achieve zero backlash,and rotaty resolution reaches 0.01° , which is suitable for the rotary positioning scenarios in semiconductor production.

Fast and Stable

With DH-Robotics' excellent drive control method, as well as precision direct drive technology, RGD series can control gripping and rotating movements perfectly. Rotation speed reaches 1500° per second.

Integrated structure l Power-off protection

The dual servo system for gripping and rotating is integrated with the drive control module, which is more compact and suitable for more scenarios. Brakes are optional for the needs of various applications.
