Dynamixel MX-28R servo motor: the twin brother of the 28T, with an extra RS485 interface

With its case in aluminium and engineering plastic and high quality metal gears, the Dynamixel MX-28R servomotor is nearly identical to the MX-28T. Like all servos in the newest Dynamixel generation, it is equipped with a driver, a gear system and a controller. It is also fitted with a contact-less absolute encoder, and offers the highest baud rate. What’s more, the MX-28R servo from Robotis embeds a programmable feedback system.

The only difference with the 28T is the RS485 multi-drop bus, the MX-28T using the half-duplex, asynchronous, serial communication protocol.

Warning ! This box contains only 6 actuators without the traditional accessories: screws, frames and horns. Only bare actuators are supplied in the box.

Endless programming possibilities

The controllers in this new generation of Robotis Dynamixel servos can be programmed using RoboPlus, but also in C. We’ve provided an MX-28R compatible SDK in the resources below.
