Brain machine/computer interface (BMI/BCI) technologies are based on analyzing brain activity to control machines and to support the communication of commands and messages. To sense brain
activities, a functional NIRS and electroencephalogram (EEG) are often employed. The devices have been developed to sense brain activities. Analysis techniques and algorithms for the NIRS and EEG
signals have also been created. Moreover, human support systems in the form of BMI/BCI applications have been developed. In the field of rehabilitation, BMI/BCI is used to control environment control systems and electric wheelchairs. In medicine, BMI/BCI is used to assist in communication for patient support. In industry, BMI/BCI is used to analyze KANSEI and develop novel entertainment games. This special issue focuses on BMI/BCI devices, techniques, and applications that support humanity. Various papers pertaining to but not limited to the following topics are welcomed: devices for EEG sensing; devices for BMI/BCI, EEG-BCI, and EEG-BMI; machine learning for BMI/BCI; deep learning for BMI/BCI; BMI and robotics; brain-inspired systems; EEG analysis techniques; fNIRS signal analysis; cognitive science for BMI/BCI; brain activity analysis; and novel approaches to BMI/BCI.

It is well known that fluid-powered systems are used practically in almost all industrial fields, including construction, manufacturing, transportation, and others. Nowadays, the rapid growth in the development of mechanical elements in fluid power systems, such as control valves, actuators, and sensors, as well as control strategies has given rise to pioneering in some novel application fields, in ways that were thought to be impossible a decade ago. High-precision positioning control using the compressible fluid of pneumatic driving systems and multi-legged robots equipped with standalone hydraulic components are simple examples. Moreover, soft robotics based on fluid-powered technologies have attracted attention not only in academia but also in human support fields that will become more important as Japan’s society ages. This special issue focuses on the state of the art in development of mechanical elements, total drive systems, motion control theory, as well as of concrete applications that use fluid-powered systems.

Micro Electro Mechanical Systems (MEMS) technology, based on the semiconductor process, enables sensors and other key components that are small in size to be fabricated cheaply. MEMS can
be integrated with circuits which enables functions such as signal processing and communication. Although there are so many sensors available to living beings, only a limited number are available
for use by robots. MEMS integrated with circuits has the potential to realize advanced robotics and mechatronics through combinations with AI and other technologies. Sensors that can recognize their environment as 3D imagers and proximity sensors are important not only for autonomous cars but also for advanced robots, and there are many other related devices, such as actuators and advanced sensors. The special issue focuses on the MEMS applications for robotics and mechatronics. Various papers pertaining to these topics are welcomed.

The Science Council of Japan’s 2008 Report, “Aiming for a Zero Traffic Accidents Society,” states that “it is necessary to establish various driver-assisting technologies on the assumption that people make mistakes,” “for advanced driving-assisting technologies, coordination between human operation and machine assistance, and social acceptability need to be evaluated,” and “new driving assistance by introduction of robotic technology and application of limited automatic driving should be considered in the future.” A wide array robotic technologies are expected to contribute to, not only providing intelligence to passenger cars and transport vehicles and their advance but also activities creating a rich future for the transportation of people and materials. Over the past decade, researchers and engineers have made many attempts to achieve this. Now, looking toward the Tokyo Olympics, we call for papers for JRM’s special issue, “Innovative Robotics and Mechatronics Technology of Modern Passenger Cars for Zeroing Traffic Accidents.”

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.

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.
