Robot-assisted Minimally Invasive Surgical techniques are becoming standard-of-care in the surgical practice. With the rapid advancement of surgical robotics, many believe that the next step is subtask automation, since it has the potential to safely improve one element of a surgery, which might be most suitable for design and execution supported by artificial intelligence. The outcome of surgery...
Industry 4.0 can be said to be the current trend of automation and data exchange in manufacturing technologies. Originally, the term “Industrie 4.0” is from a project in the high-tech strategy of the German government, which hope to promote the computerization of manufacturing. Usually involves terms like cyber-physical systems, Internet of things, amd cloud computing. For now, Industry 4.0 becomes...
The task to distinguish between soft tissues by testing their mechanical properties is often referred to as the primary cognitive role of haptic devices. It is a common view that today's surgical simulators that are using haptic interfaces should rely on simple mechanical models of soft tissues, instead of complex, parameterized finite element models, thus enhancing real-time operation and focusing...
This paper is about extended application of virtual engineering principles, methodologies, and systems as a possible answer to urgent need for integrated industrial, research, and higher educational programs and processes. One of the motivations is the changed world of engineering which requires quick utilization of new findings as new context. At the same time, development of virtual engineering...
Development of modeling systems for product engineering or experimental purpose was enforced by need for engineering of cooperating systems operated multidisciplinary products during the recent years. As result the requirements, functional, logical, and physical (RFLP) structured model replaces the pure physical level representations in industrial engineering modeling systems at leading industries...
Reliable force control is one of the key components of modern robotic teleoperation. The performance of these systems, in terms of safety and stability, largely depends on the controller design, as it is desired to deal with various disturbing conditions, such as uncertainties of the model parameters or latency-induced problems. This work presents a polytopic quasi-linear parameter-varying (qLPV)...
It is a great pleasure and honor to greet you to the annual conference, 2016 IEEE International Conference on Systems, Man, and Cybernetics (SMC 2016) at Budapest, Hungary. SMC 2016 is the flagship conference of the IEEE Systems, Man, and Cybernetics Society. It provides an international forum for researchers and participants to report up-to-the-minute innovation and development, summarize state-of-the-art,...
In-silico modeling is an important part of biomedical engineering. Advanced controllers providing high quality control can be validated through it checking if the available mathematical model of the given biomedical process produces the desired output. However, due to high patient variability the advanced linear control methods applied on linearized models could produce several distortions compared...
Advanced surgical robotic systems aim to offer improved capabilities through automated low-level functions. In the applications, soft tissue mechanics and tool-tissue interaction modeling play an important role in achieving optimal control, relying on model-based control methods. This approach allows for addressing crucial issues during teleoperation, such as time-delay, state observation or stability...
Complexity is the most common feature of the practical tasks to be solved in control technology. Grasping only a little particular segment of reality, often referred to as “model building”, provides us with imprecise and incomplete models of certain subsystems that operate in dynamic interaction with their neglected environment. The classical method of Model Predictive Control (MPC) assumes that our...
This paper is about new methods which are contributions to system level interdisciplinary definition of multidisciplinary engineering structure (ES). Definition of ES is flexible. It may be product, functional unit, or experimental configuration of components. Developers of engineering modeling systems were forced to extend conventional physical level representations with system level representations...
Robotics is becoming a mainstream phenomenon, entering all areas of our lives. In addition to cutting-edge research and development, robotics is becoming equally important in the classroom and home education. Numerous educational kits have appeared on the market recently, ranging from simple toolboxes and toys to complex, configurable R&D sets. Their value in formal teaching lies in modularity...
Eversince computer technology entered the operating room (OR), surgery has gone through one of the greatest changes in the history of medicine, and now we are foreseeing the age of the digital OR. The range of the novel applications spans from intra-operative navigation to the development of autonomous suturing tools. More recently, after 20 years of experience with pre-programmed, image-guided and...
The paper gives an overview of a number of successful research and development projects in the area of geometric measurement covering different features in the manufacturing industry. The various instruments presented in the subsequent paragraphs are used either by calibration laboratories or quality control departments of manufacturing companies. Each description starts with a short specification,...
On the way of moving engineering activities into generic contextual and self-adaptive virtual space, this paper introduces a new concept of integration virtual representation and simulation background for research, product development, and higher education processes in the form of appropriately configured multidisciplinary professional engineering models. These models can be organized in advanced...
New comprehensively integrated, model and simulation based, and intellectual property driven way of product engineering which also serves fundamental, problem specific, and product specific research motivated a new concept called as multifunctional engineering space (MES). The MES concept was defined as new bridge which connects industrial product engineering processes, activities to reuse industrial...
Achieving reliable force control is one of the main design goals of robotic teleoperation. It is essential to grant safe and stable performance of these systems, regarding HMI control, even under major disturbing conditions such as time delay or model parameter uncertainties. This paper discusses the systematic derivation of polytopic qLPV model from the nonlinear dynamics of typical soft tissues...
Theoretical, methodological and systemic resources were developed on the way towards product system model centered and intellectual property driven engineering during the past decade. These developments enhanced communications between humans as well as between humans and physical objects. Leading industries utilized new generation of product lifecycle management (PLM) systems in connection with smart...
With blood purification the life of a person suffering by kidney malfunction can be saved or the quality of her/his life can be increased. This is the purpose of hemodialysis machines, where the blood of the patient is filtered (cleared) in an extracorporeal tube system. Here peristaltic pumps are responsible for the fluid transport, where the strict control is a serious need, in order to maintain...
Under the conceptual framework of Cognitive Info communications, a recently published definition of Cognitive Control draws twofold sense characterizing the goals of this branch of systems and control science. On the one hand, Cognitive Control aims to apply the results of control theory to regulate natural or artificial cognitive systems. While on the other hand it points toward the modeling of cognitive...
