Robotics has reached a top technological level in recent years, a level at which it can be successfully used not only in structured spaces (for less complex applications) but also increasingly in unstructured spaces. Robotics technology is now used effectively in hospitals for rehabilitation and assistive devices, in the home for domestic applications, in the space for autonomous robots and automated vehicles, in amusement parks for entertainment attractions, and on the ground for military applications. In industrial applications, robotics has enlarged its scope with high-speed robots, cooperative robots, and smart robotic devices for production set-ups. These new applications have created new challenges in robotics. New materials have been developed to make frames lighter and smarter, new actuators and sensors have been made in compliance with specific applications and for more advanced performance, new flexible gripper devices have been produced with superior control systems, and new interfaces have been developed that are integrated with the devices and easier to use. This special issue features 18 research articles related to the latest research results and practical case studies in robotics technology. Subjects include robots for rehabilitation, robots as assistive devices, robots for agriculture, robots for exploration, robots for automation and industrial applications, service robots, new actuators, new sensors, new gripping devices, new control strategies, and robotic systems. We deeply appreciate the careful efforts of all the authors and thank the reviewers for their incisive efforts. Without these contributions, this special issue could not have been printed. We hope that this special issue will trigger further research on robotics technology. Finally a special memory of Cesare Rossi, one of the authors, that died suddenly after the preparation of the manuscript.

Machine Interaction

Soft actuators and robotic devices have been increasingly applied to the field of rehabilitation and assistance, where safe human and machine interaction is of particular importance. Compared with their widely used rigid counterparts, soft actuators and robotic devices can provide a range of significant advantages; these include safe interaction, a range of complex motions, ease of fabrication and resilience to a variety of environments. In recent decades, significant effort has been invested in the development of soft rehabilitation and assistive devices for improving a range of medical treatments and quality of life. This review provides an overview of the current state-of-the-art in soft actuators and robotic devices for rehabilitation and assistance, in particular systems that achieve actuation by pneumatic and hydraulic fluid-power, electrical motors, chemical reactions and soft active materials such as dielectric elastomers, shape memory alloys, magnetoactive elastomers, liquid crystal elastomers and piezoelectric materials. Current research on soft rehabilitation and assistive devices is in its infancy, and new device designs and control strategies for improved performance and safe human-machine interaction are identified as particularly untapped areas of research. Finally, insights into future research directions are outlined. Corresponding author(s) Email:   [email protected], [email protected]

Recently, intelligent systems are desired to support human in real world such as advanced safe vehicles, home service robots, wearable computing devices, and intelligent home security systems. Such intelligent systems require extremely high computational power that exceeds that of state-of-the-art microprocessors. They also require <ul><li>Low power consumption</li><li>Low latency from input to output</li><li>Compactness</li></ul> Special-purpose processors called ""system LSIs"" play an essential role in meeting these requirements. This special issue focuses on the latest advances in system LSIs for real-world intelligent systems. One of their most important tasks is sensing environmental information such as visual information. Image and angle sensors, for example, are implemented in system LSIs. Image processing is the most time-consuming in real-world intelligent systems due to the extremely large amount of data. To overcome this problem, novel parallel architectures are presented. Electrical wires between processing modules must be minimized to make intelligent systems compact. High-speed serial data transfer is one most effective way to minimize the electrical wires. An architecture that handles processing order based on task priorities is a key to low latency. Processing of human interfaces such as face detection and speech recognition are also important factors in making intelligent systems user-friendly. I thank the authors of the articles in this issue for their effort and contributions, and the members of the Editorial Board for their cooperation.

Energy storage systems (ESS) are becoming essential as a solution for troublesome industrial systems. This study focuses on the application of a type of ESS, a high-power technology known in the literature as supercapacitors or electric double layer capacitors (EDLC). This technology has had a huge impact during the last decade on research related to the electric traction drives, renewable sources and powergrids. Related to this aspect, this paper summarizes the most relevant scientific publications in the last five years that study the use of supercapacitor technology (SCs) in electric traction applications (drives for rail vehicles and drives for road vehicles), generation systems for renewable energy (wind, solar and wave energy), and connection systems to the electric grid (voltage and frequency regulation and microgrids). The technology based on EDLC and the practical aspects that must be taken into account in the op-eration of these systems in industrial applications are briefly described. For each of the aforementioned applications, it is described how the problems are solved by using the energy storage technology, drawing the solutions proposed by different authors. Special attention is paid to the control strategies when combining SCs with other technologies, such as batteries. As a summary, some conclusions are collected drawn from the publications analyzed, evaluating the aspects in which it is necessary to conduct further research in order to facilitate the integration of EDLC technology.

The use of magnetic bearing in industrial applications has increased due to their unique properties. Nowadays efficiency and predictability in handling rotors on magnetic bearings is asked with the same standard as conventional rotors on oil or roller bearings. First of all one must be aware of the special technical properties of magnetic bearing designs. The dynamic behavior of the rotor combined with requirements of the application define the desired bearing characteristic. With modern tools covering the mechanical aspects as well as the electronic controllers and their digital implementation on a DSP, these properties can be designed. However, despite the use of such efficient tools engineering practice is needed. Therefore this paper summarizes the major steps in the control design process of industrial applications. Three rotors supported on magnetic bearing with their specific dynamic behavior are presented: a very small high speed spindle (120,000 rpm); a small industrial turbo molecular pump rotor (36,000 rpm); and a large multistage centrifugal compressor (600 to 6300 rmp). The results of the analyses and their experimental verification are given.

Abstract Laser cutting is a well-established industrial process for sheet metal applications. However, cutting thick plates is still accompanied by problems because of the characteristic limited process parameter window. Since cutting by means of fiber lasers has become dominant, tailored solutions are required in such systems for industrial applications. The development of a robust real-time monitoring system, which adapts the process parameters according to a specific quality requirement, implies a significant step forward towards automated laser cutting and increases the process robustness and performance. In this work, a coaxial multi-sensor monitoring system is tested for fiber laser cutting of stainless steel thick plates. A high-speed camera and a photodiode sensor have been selected for this investigation. Experiments at different cutting speeds, representing primary cut quality cases, have been conducted and various features of the obtained process zone signals have been examined. Finally, the feasibility of industrial application of the developed setup for high-power fiber laser cutting is discussed, followed by several implementation recommendations.
