The MX-64R is a Dynamixel servomotor, with high-level control features and very precise. It is more powerful than the MX-28R but less than the MX-106R.

This video illustrates the capabilities and the existing application for Dynamixel servomotors:
The servomotors have to be linked to a main controller (CM-900, CM-700, CM-5, CM-510 or CM-530) to be commanded. The progams are made with RoboPlus, which allow really easy programmation, without much previous knowledge.
The most recent main controllers support embedded C and there is a SDK for you to developp your own applications.
The MX-64T and MX-64R are new Dynamixel servomotors in the MX range. They replace and improve the RX-64 servomotor with a new absolute contactless encoder with 12 bit resolution (4096 positions), can be positionned over 360° in joint mode (251° previously), can be speed controlled in wheel mode and estimate their torque based on current.
Moreover they are controlled with a PID (proportional integral derivative ), which parameters can be set servomotor by servomotor. Admissible values are between 0 and 255 and the PID coefficients are modified with the following formulas:
The case of the RX-64 has also been lightly modified, the MX-64R servomotor is therefore not compatible with the HN05-N101/T101 horn.
The Dynamixel servomotor MX-64R supports the MS485 communication protocol (when MX-64T supports TTS communication) with high speed (3Mbs), it is compatible with the CM-700 controller. Warning, the operating voltage is not the same as the RX-64 voltage.
All the technical specifications of the Dynamixel MX-64R actuator are available on the website of the manufacturer at http://support.robotis.com/en/product/dynamixel/mx_series/mx-64.htm
This document offers an overview on the characteristics of all the Dynamixel servomotors.

The chart below compare the Dynamixel actuators on their performance. Servomotors are differentiated by communication type (and the MX range proposes both protocols).
