Overview:

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

The Dynamixel XM430-W350-R is a High Performance RS-485 Servo in the Dynamixel X-Series. Using the Same form factor as the other 430 series servos in the X-Series line, the Dynamixel XM430-W350-R has the highest Torque rating in the 430 series in the X-Series line, making it well suited for robotic tasks requiring strength.

Dynamixel X-Series is a new line-up of high performance networked actuator module, which has been widely used for building multi-joint robots with reliability and expandability.

Various Operating Modes: Velocity Control, Position Control, Extended Position Control, PWM Control
Profile Control for Smooth Motion Planning
Hollow Back Case Minimizes Cable Stress (3-way-routing)
Direct Screw Assembly to the Case (without Nut Insert)
Energy Saving with Reduced Current

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)
