🌏 English, 한국어

This helper is a wrapper for the Dynamixel-SDK. With this, configure and drive your motor more quickly. You do not need to know how the SDK works. In other words, this helper makes it easy to modify the control table.

pip install dynamixel_helper --user

🐣 Simple Example

The following code is an example of turning on the motor torque.

helper = DxlHelper("preset/{my_robot}.json")
motor = helper.get_motor(0)  # id: 0

🚀 Getting Started


  1. pip (package manager)

    # Python 2
    sudo apt install python-pip
    python -m pip install -U pip
    # Python 3
    sudo apt install python3-pip
    python3 -m pip install -U pip
  2. Dynamixel SDK

    CAUTION💥: Please install the pip before installing the Dynamixel SDK. Otherwise, when you install this Dynamixel Helper, you will get an dependency error of Dynamixel SDK.

    You need to install the official Dynamixel SDK before using this helper.

    Click here: Dynamixel SDK Installation

    1. Clone the official SDK repository into your custom folder, for example, I created ~/lib.

      git clone
    2. Go into the folder /DynamixelSDK/python of your cloned SDK.

      cd ${your_download_path}/DynamixelSDK/python
    3. Run with --user option to install the library. Administrator privileges, a.k.a. sudo, are not recommended. More information here.

      python install --user


Simply type pip command below to install this helper.

pip install dynamixel_helper --user
