(5 years 2 months) 1. Software architecture designing. Selecting or retrofitting fitted design pattern combinations, in consideration of hardware limitation, performance, extensibility, configurability, and maintenance difficulty. Software developments are based on well-designed UML(Unified ModelingLanguage). Database or other data storage methods are also involved in achieving specific features, for example, statistical process control. 2. Integrating hardware into the system. Creating the hardware abstract layer, and seamlessly integrating complex hardware components into the system based on their technical characteristics, operational processes, and communication methods. The motion component includes step-motor controller, high-performance servo-driver, and industrial robots. The X-ray tube and Camera, are working together to acquire projection(x-rayimage) of the inspected items. EtherCAT, CANOpen and Ethernet/IP Fieldbus components, which include safety relay, I/O module, remote instrument, etc. Workpiece identification devices, Barcode reader, RFID Reader, etc. 3. Optimizing the performance of existing sub-systems or features. To optimize the performance of sub-systems, or functionality, new methods, mechanisms, or strategies would be used. For instance, Multi-processes, multi-threads, Win32 API, Real-time operation systems, etc. Create the prototype of the sub-systems and their feature, and transfer them to the industrial solution. 4. Continuous development, integration, and deployment. Using the methodology DevOps for software development, testing, and deploying, furthermore, they are used for internal-team and cross-functional team management, cooperation, and interaction as well. 5. Maintaining existing systems. Solving the reported issues from the application/service team or customers. Extending functionalities of the system, and providing internal technical training to the application/service team.

(1 year 7 months) 1. The communication interface between the robot/motion controller and Wandelbots Robot Process Teaching System. Using Visual Studio Code(C/C++ and CMake) or Visual Studio(C#) to develop robot abstraction layer and communication layer on the robot trajectory teaching system side. Using C, C++, or Manufacturer-defined programming languages to develop the communication module at the robot/motion controller side(UR, ABB, Codesys,Servotronix). In regard to the communication module, mainly includes the socket message server/client module, serialization/de-serialization module, interpretation module, and data optimization module. Integrating the existing robot SDK into the relevant software layer of the Wandelbots robot motion trajectory teaching System. 2. Robot motion application development. Using the robot/motion controller programming language(ABB-Rapid, SoftMC-Basic, Structured Text, etc.) or C/C++ to develop well-structured and object- oriented motion applications in order to couple with the robot motion trajectory teaching system. PID controllers, interpolators, or other algorithms need to be developed for optimizing final movement performance. RobotDK, MATLAB, and Excel VBA are used for simulation, evaluation, and data analysis. 3. Software development management. Using agile software development tools(Jira, Git) for managing daily tasks and coordinating with another developer or team. Doxygen and Markdown are used as the main tools for writing software development-related documents. Additionally, well-understanding of the methodology of the software Semantic Versioning. 4. Electrical engineering Using EPLAN to manage the whole process of deploying customized electrical systems that are parts of the Wandelbots Robot Process Teaching System. In regard to electrical system deployment, which includes designing electrical schemes, selecting the parts, assembling, debugging, and optimizing.
