Many very large-scale systems are networks of cyber-physical systems in which humans and autonomous software agents cooperate. To make the cooperation safe for the humans involved, the systems have to follow protocols with rigid real-time and real-space properties, but they also need to be capable of making competitive and collaborative decisions with varying rewards and penalties. Due to these tough requirements, the construction of system control software is often very difficult. This calls for applying a model-based engineering approach, which allows one to formally express the time and space properties and use them as guidance for the whole engineering process from requirement definition via system design to software development. Moreover, it is beneficial, if one can verify with acceptable effort, that the time and space requirements are preserved throughout the development steps. This paper focuses on modelling spatio-temporal properties and their model-checking and simulation using different analysis tools in combination with the methods and tool extensions proposed here. To this end, we provide an informal overview of CASTeL, our CASTeLogic. CASTeL is stochastic and includes real-time concurrency and real-space distribution.

RMIT University's Practical Space Weather Prediction Laboratory

Space weather is a key component in the daily operation of many technological systems and applications; including large-scale power grids, high-frequency radio systems and satellite systems. As the international space sector continues to boom, accessible space weather products, tools and education are increasingly important to ensure that space actors (both old and new) are equipped with the knowledge of how space weather influences their activities and applications. At RMIT University, the initiative was taken to develop a Space Weather Prediction Laboratory exercise for students as part of its new offering of a Bachelor Degree in Space Science in 2020. This new Space Weather Prediction Lab exercise is offered as part of an undergraduate course on `Space Exploration', which has a diverse student in-take, including students with no background in physics; a key detail in the design of the Lab. The aims of the Space Weather Prediction Lab were to: (1) Provide a short and intense introduction to the near-Earth space environment and its impact on various human technologies; (2) Give students `hands-on' training in data analysis, interpretation and communication; and (3) Create an immersive space science experience for students that encourages learning, scientific transparency and teamwork. The format of the lab that was developed can be easily scaled in difficulty to suit the students' technical level, either by including more/less space weather datasets in the analysis or by analyzing more/less complicated space weather events. The details of the Space Weather Prediction Lab developed and taught at RMIT in 2020, in both face-to-face and online formats, are presented.

Abstract—We present work on structuring robotics simulation scenarios into components. Components can comprise simulation entities with a physical counterpart such as automated guided vehicles, drones, robots and machines. Components are typically further structured into sub-components, e.g., a robot arm or a gripper and they can be used to build digital twins. Different aspects for classifying components can be distinguished, here, we are concentrating on composability, performance and fidelity. In this paper, we are concerned with components in the robotics simulation tool Gazebo used with Robot Operating System (ROS). Several structured scenario cases are created and we are investigating how these scenarios behave in Gazebo with respect to performance and fidelity for selected cases.



On Decision Support for Remote Industrial Facilities using the Collaborative Engineering Framework

February 2018

21 Reads

Means to support collaboration for remote industrial facilities such as mining are an important topic, especially in Australia, where major mining sites can be more than a thousand kilometers from population centres. Software-based collaboration and maintenance solutions can help to reduce costs associated with these remote facilities. In this paper, we report on our collaborative engineering project providing a decision support solution tailored for Australian needs. We present two application examples: one related to incident handling in industrial automation, the other one in the area of smart energy systems.

In this report, we present our work in visualization and augmented reality technologies supporting collaboration in manufacturing automation. Our approach is based on (i) analysis based on spatial models of automation environments, (ii) next-generation controllers based on single board computers, (iii) cloud-, service- and web-based technologies and (iv) an emphasis on experimental development using real automation equipment. The contribution of this paper is the documentation of two new demonstrators, one for distributed viewing of 3D scans of factory environments, and another for real time augmented reality display of the status of a manufacturing plant, each based on technologies under development in our lab and in particular applied to a mini-factory.

This paper presents how collaborative industrial project are embedded into engineering curriculum at two departments: School of Science and the School of Engineering, at RMIT University, Australia. We introduce general structure of the industrial projects as Work Integrated Learning (WIL) modules, as well as provide a number of examples of recently completed projects. Industrial summer projects, which were running in the years 2015/16 in collaboration with ANZ, ABB, Alfred Hospital, etc., were pipelined with final year projects from the School of Engineering as well as with the Software Engineering Projects (Bachelor and Master level) from the School of Science. The goal of these projects was to enable continuity of activities as per industry requirements and enhance learning experience, as well as, employability of the students. All the projects were successfully completed, also receiving positive feedback from industry partners. Some of the projects led to student’s employment within the companies that have sponsored the projects. With this approach, Future Designers Grant from the Department of State Development, Business and Innovation, Victoria, was efficiently implemented and a new product developed. After receiving Bosch Venture Forum Award in Germany, in June 2015 industry collaboration has extended to new partner, School of Science and activities continued over the summer. New design is implanted as well as large number of improvements.

In this paper, we present our work on monitoring of control software behavior for PLCs. In particular, we are looking at IEC 61499-based software specifications. Monitoring is done remotely, i.e., the interface behavior of function blocks is streamed to a cloud-based service. Specifications are realized using formal languages such as 1) regular expressions, 2) timed automata, 3) temporal logic. Monitors can be automatically generated from these languages. Using our specifications, we are able to detect abnormal behavior in control software such as timing changes that can, e.g., show the presence of memory leaks or a virus. We demonstrate our ideas using an example.

... For instance, a recent study (Zhang et al., 2021) on virtual surgical training systems enabled by modern medical technologies and VR shows that the design of collision detection and force feedback algorithms is essential to ensure transparency and immersion for trainees. The Virtual Experiences Laboratory (VXLab) at RMIT University visualized time series data as static images, and the solar wind imagery in a looping video format, providing an immersive space science experience for students that fosters learning, cooperation and "transparent data sharing" (Carter et al., 2022). Additionally, new technologies provide opportunities to solve problems regarding lack of transparency. ...
