Japan has infrastructure facilities, including bridges, tunnels, roads, etc., intensively built during the period of rapid economic growth. These facilities are naturally aging rapidly now. As the percentage of facilities fifty years old or older is expected to increase at an accelerating pace over the next twenty years, it is necessary that those infrastructures aging simultaneously be strategically maintained and updated those infrastructures aging. At present, Japan has about 699,000 bridges and about 10,300 tunnels.
Under the existing conditions, however, almost all of the inspections of infrastructure facilities depend on a labor-intensive approach. If this continues, inspecting all the infrastructure facilities will take too long, resulting in the risk of the collapse of facilities before their inspection and maintenance are completed. In response to this, there is now a growing need for significantly more efficient infrastructure maintenance and inspection utilizing robotics and mechatronics technologies. A few projects have already been launched.
Focusing on systems that are under development or have recently been developed for infrastructure maintenance and inspection, this special issue is calling for papers on robotics and mechatronics that would contribute to such technologies. In addition to research papers, development reports are also welcomed.

As social robot research has advanced, the interaction distance between people and robots has decreased. Indeed, although we once needed to keep a certain amount of physical distance from traditional industrial robots for safety, we now interact with social robots in such close proximity that we can actually touch. Since social robots are at work in our daily environments, it is essential that our designs keep close interactions with humans in mind, so this special issue focuses on close humanrobot interactions. As robotics, engineering, and behavioral sciences all fall within its scope, papers related to sensing, actuation, control mechanisms, haptics, social touch interaction, affective interaction, conversational interaction, verbal/non-verbal behavior design, cognitive science, behavioral science, etc. are welcome. Conceptual papers focusing on new ideas and/or methods are welcomed for this special issue as well.

Recent advancements and sophistications in robotics and mechatronics technologies have created challenges for individual research groups to complete their work independently. Under these circumstances, research institutes, such as universities, have established research centers to promote advanced and sophisticated technological innovations by centralizing humans and material assets. This special issue is planned to globally expose the cutting-edge research outcomes from these research centers in universities as well as companies and governmental agencies. The contents of this special issue will consist of one-page brief introductions to these research centers (page-charge free) and of a few journal papers and development reports from each listed organization. The papers and reports submitted to this special issue will be peer-reviewed base on the regular rules of the journal. All members affiliated with such research centers are hereby cordially invited to contribute papers or reports to this special issue of the Journal of Robotics and Mechatronics.

The special issue, “Machine Learning for Robotics and Swarm Systems,” is focused on machine learning techniques and its application to the field of robotics including swarm systems. Swarm systems were born in a field of robotics as a kind of distributed autonomous robotic systems with the concept of the emergent methodology for extremely redundant systems. They typically consist of homogeneous autonomous robots, similar to living animals that build swarms. Recently, machine learning, such as deep learning, has been more remarkable for controlling the behaviors of these robots in real world. The topics included in this special issue are not only recent advances of machine learning techniques and its applications in the field of robotics and swarm systems, but also the controlling mechanism for multi-robots, such as evolutionary computation or other soft computing methods. Proposals involving new ideas or methods in this field are also welcome.

Miniaturization of computers and electronic devices as well as advancements in processing algorithms have enabled the development and practical use of several wearable devices. Other devices such as power assist robots for reducing the burden of work or wearable sensors for measuring physical activity and health condition of people and animals also provide various uses and are available in several forms. In Japan, Society 5.0 is attracting significant attention as one of the important technologies for a human-centered society that achieves both economic development and solutions to social problems. A society that can benefit from wearable devices anytime and anywhere is thus being realized. In this special issue, we focus on robotics and mechatronics technology for next generation wearable devices to realize a progressive society; the technologies in focus include wearable systems and their principles and fabrication, AI, IoT, and related technologies of practical use.

Control engineering and instrumentation engineering have significantly contributed to the improvement of industrial productivity, saving of resources and energy, and enrichment of our lives. They have become important cross-cutting study fields not only covering engineering but also having strong relations with the environment, society, and economy. Therefore, various studies have been conducted on the educational methods of related technologies at educational institutes and companies. With this background, we planned this special issue with the latest studies on the instruction and evaluation methods for education on control engineering, instrumentation engineering, and control technologies, expecting its contribution to further development in the future.

The Journal of Robotics and Mechatronics (JRM) is calling for not only research papers from university researchers but also development reports from corporate engineers and university or college students. If you would like to present to our readers a system or technology you have developed in the field of robotics and mechatronics, you are encouraged to write a development report, even if you find difficulty in writing a research paper. Once published, your report will appear online free of charge and be shared with readers all over the world. JRM is an English journal, but if you are not confident in your English skills, you can write your report in Japanese and we will translate it for you. We are looking forward to receiving your development reports on, such as, product development in your company or an achievement in a robotics competition.
