Trademarks

YASKAWA, MOTOMAN, DX100, DX200, YRC1000, YRC1000micro, MOTOMAN NEXT, FS100, ERC, XRC, MRC, INFORM and MotoPlus are trademarks or registered trademarks of YASKAWA Electric Corporation or its affiliates. Other product names, company names and brands in this documentation belong to their owners. They are used only to say which equipment the SDK communicates with.

UnderAutomation is an independent software publisher. It is not affiliated with, endorsed by or sponsored by YASKAWA Electric Corporation or its affiliates. This SDK is not a Yaskawa product. Yaskawa does not certify, review or support it. UnderAutomation provides the support of the SDK.

Protocols and interoperability

The SDK communicates with Yaskawa Motoman controllers (YRC1000 (micro), MOTOMAN NEXT, DX100 / DX200, FS100, ERC / XRC / MRC) through the functions of the controller: the High Speed Ethernet Server, the Ethernet Server, the web server and the FTP server (see Choose a protocol).

The SDK contains no Yaskawa source code and no Yaskawa binary. It installs nothing on the controller. The functions you use must be enabled on the controller, and your controller must have the options that the features you use need.

The robot models of the offline kinematics are described by their nominal Denavit-Hartenberg parameters. They are given to compute positions on a PC, and do not replace the data of the robot manufacturer.

Responsible use

The SDK can change the state of an industrial robot: it can switch the servos on, start jobs, move the arm and write I/O, variables and files. A robot is dangerous machinery.

The safety of people and machines is the responsibility of the integrator. The SDK does not replace a safety system. You are responsible for the risk assessment of your application and for its compliance with the machinery regulations that apply to you. Test your application at reduced speed, in a cell with its safety functions active, before you use it in production.

Third-party components

The SDK contains code from the project below. UnderAutomation modified this code (namespaces renamed, types made internal, code adapted) and the DLL is obfuscated. This component stays under its own license. The copyright notice and the full license text are in the file THIRD-PARTY-NOTICES.txt, delivered with the DLL, the NuGet package, the Python package and the source code package.

These packages are installed by NuGet or pip from their publishers. UnderAutomation does not redistribute them:
