DYNAMIXEL Workbench Support Discontinuation and Archive Notice

We have decided to discontinue official support for DYNAMIXEL Workbench, and the repository will be archived accordingly.

As we move into the era of Physical AI, the ROBOTIS Open Source Team recommends using ROS 2 Control for controlling DYNAMIXEL actuators. For ROS 2-based applications, we especially recommend using the DYNAMIXEL Hardware Interface as the preferred approach going forward. https://github.com/ROBOTIS-GIT/dynamixel_hardware_interface

If you have any questions regarding DYNAMIXEL Workbench, other legacy software, or ROBOTIS products and technologies, please contact us through the ROBOTIS Contact page: https://docs.robotis.com/docs/common/contact

We sincerely thank everyone who has used, supported, and contributed to DYNAMIXEL Workbench over the years. We greatly appreciate your continued interest and support.
