Overview:

Dynamixel is a robot exclusive smart actuator with fully integrated DC Motor + Reduction Gearhead + Controller + Driver + Network in one DC servo module.

  • Advanced durability, degree of precision, and wider control zone were achieved thanks to the newly applied contactless absolute encoder
  • 360 degrees position control without dead zone
  • 4,096 precise resolution by 0.088 degrees
  • Speed control at endless turn mode
  • Reliability and accuracy were advanced in the position control through PID control
  • High baud rate up to 4.5Mbps

Shape of the AX-series + durability of the MX-series

The MX-series is a new type of DYNAMIXEL with numerous advanced functions, such as precise speed control, 360 degrees of accurate positioning, PID control, and high speed communication.


MX actuator

The MX actuator contains a new contactless magnetic rotary encoder for accurate angular movement over a full 360 degrees.

360 degree 4096 Steps

The absolute angle measurements provide instant and reliable information of the angular position with a resolution of 12 bits = 4096 positions within 360 degrees. This delivers fine angle movements accurate to 0.088 degrees.

PID Control

The MX-series also integrates a new PID Control, which automatically and accurately corrects for naturally occurring errors such as backlash (caused by small gaps in the gears). Thus, positioning is more reliable and in compliance to specifications.


Precise speed is controlled through serial data and has a resolution of 10 bits to accurately adjust the high speed movements into 1023 increments of speed control.

Actuator status, commands, and sensor information are easily provided through readable memory and made available as a serial bit stream through TTL communication with a baud rate of up to 4.5 Mbps (4,500,000 bits per second).

Dynamixel SDK:

Dynamixel SDK

Provides various control environment just like Dynamixel

Dynamixel SDK is a software development kit that provides Dynamixel control functions using packet communication. The API of Dynamixel SDK is designed for Dynamixel actuators and Dynamixel-based platforms. You need to be familiar with C/C++ programming language for right use of the software. This e-Manual provides comprehensive information on ROBOTIS products and applications.

Supported Protocols

To control Dynamixel, communication should be established according to the protocol of Dynamixel. There are versions 1.0 and 2.0 of the Dynamixel protocol. The Dynamixel SDK supports both, and the user can use both protocols simultaneously using the Dynamixel SDK. Refer to the following manuals for details on the protocols.

  • Dynamixel Protocol 1.0
  • Dynamixel Protocol 2.0 (Recommended protocoltype)

Supported Devices

The Dynamixel SDK can be used on PCs such as desktops or laptops, as well as on tablets, and also on SBCs like Raspberry Pi and UpBoards. In addition, it can be used with embedded boards that support the Arduino IDE. Dynamixel uses TTL and RS485 communication. In order to use computer and Dynamixel, we recommend USB2Dynamixel or U2D2 as interface device.

Supported Operating Systems

The Dynamixel SDK supports all three operating systems: Windows, Linux, and MacOS.

Supported Languages

The Dynamixel SDK supports various programming languages: C, C++, C#, Python, Java, MATLAB and LabVIEW.
In addition, Dynamixel SDK supports ROS, so it can be used as ROS library using C++ or Python modules.

  • C: *Dynamic library and source code of this library and examples
  • C#, Java, MATLAB, LabVIEW: Support based on dynamic library using C language
  • C++: *Dynamic library and source code of this library and examples
  • Python: Python module and examples
  • ROS: ROS library using C++ and Python modules

(* Dynamic library (*.dll, *.so, and *.dylib files) / .dll: dynamic-link library on Windows / .so: shared object on Linux / .dylib: dynamic library on macOS)
