Overview:
The AX-12A servo actuator from Robotis is the most advanced actuator on the market in this price range and has become the defacto standard for the next generation of hobby robotics. The AX-12A robot servo has the ability to track its speed, temperature, shaft position, voltage, and load. As if this weren't enough, the control algorithm used to maintain shaft position on the ax-12 actuator can be adjusted individually for each servo, allowing you to control the speed and strength of the motor's response. All of the sensor management and position control is handled by the servo's built-in microcontroller. This distributed approach leaves your main controller free to perform other functions.
Dynamixel is a robot exclusive smart actuator with fully integrated DC Motor + Reduction Gearhead + Controller + Driver + Network in one DC servo module.
Dynamixel AX-series are used in ROBOTIS STEM, Premium, and GP. You can easily create various types of robots such as humanoid, 4 legged and 6 legged robot with the AX-series. It can also be used as a wheel so that you can create a robot with a combination of wheel type and joint type in a single module.
By using a variety of high-strength engineering plastic option frames or by printing frames using a 3D printer, you can produce any type of robot at a low cost.

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)
