On March 11, 2011, an accident occurred at Fukushima Daiichi Nuclear Power Station (FDNPS) of the Tokyo Electric Power Company Holdings (TEPCO), and radiation levels in the reactor buildings have reached high levels due to the spread of radioactive contamination. Therefore, in order to reduce the risk of radiation exposure to workers during decommissioning work at FDNPS, it has become essential to utilize remote control system based on the technologies and knowledge in the field of robotics and mechatronics. The decommissioning of FDNPS is expected to take 30–40 years, and although 10 years have passed since the accident, there are still many unknowns at FDNPS. In addition, difficult tasks such as of fuel debris retrieval from the Primary Containment Vessel (PCV) await in the future, and the development of technologies to accomplish this is currently underway. Since the experience and knowledge of technological development gained through decommissioning task should be shared widely. This special issue is to collect review, technical papers related to robotic, mechatronic and information systems for decommissioning, and also development reports on remote control technologies used in decommissioning of FDNPS and also the technologies being developed for that. We also welcome a wide range of topics related to decommissioning technology.

Regular paper submission is always welcome. Submitted paper is reviewed at all times, and when it is accepted for publication, it will appear in the near issue.
一般投稿論文は常に受け付けております。随時査読を行い、採録になり次第出版日の近い号に掲載されます。

つくばチャレンジは2007年の開始以来，電子デバイスの高性能化によるLidarの三次元化とそれを利用する制御技術の進歩によって自律移動性能が向上し，課題を達成するロボットが増えてきました．さらなる人間との共存を進めるために探索や横断歩道の横断等が追加されましたが，季節の移り変わりや気象条件の変化があっても確実に動作することの難しさも見えてきました．障害物地図による自己位置推定による自律制御技術はほぼ確立されたものと言えますが，技術継承のための人材教育と研究の進展を両立することが求められています．中之島ロボットチャレンジでは，2025年の大阪万博に向けた自動ゴミ回収ロボットの実現を目指した研究開発が進行しています．本年の本走行が終了し，収集した実験データをまとめる時期となりました．本特集号では制御の成功例または失敗例の本質を分析して共有することで技術の向上を目指しています．チャレンジ参加者や自律移動ロボット研究者からの投稿をお待ちしています．

The Tsukuba Challenge, launched in 2007, has seen an increasing number of robots accomplish their assigned tasks as the performance of their autonomous navigation systems has improved. This improved performance has mainly stemmed from 3D Lidar systems that have been realized using high-performance electronic devices, and advanced control technologies that take advantage of these systems. To further promote the coexistence of robots with human beings, additional tasks, such as searching, crossing a crosswalk, etc., have been assigned to robots over time, but it has been found that they still have some difficulty operating securely when the seasons or weather conditions change. While autonomous control technologies using self-localization by means of obstacle maps have become more or less established, what is now needed is the human resource training for technological succession to be made compatible with the research progress. Also, the Nakanoshima Robot Challenge has encouraged the research and development of autonomous trash collection robots that are intended for use at the Osaka-Kansai Japan Expo 2025. As both Challenges’ final runs were completed in 2022, it is now time to collate the data collected during these experiments.
This special issue on “Autonomous Robotics Challenge” aims to help improve autonomous robotics by analyzing and sharing the essence of successes and/or failures experienced in controlling autonomous mobile robots. In the above-mentioned context, you, whether a Challenge participant or an autonomous mobile robot researcher, are cordially invited to contribute your papers to this special issue.

“Micro Electro-Mechanical System” (MEMS) is a mechatronics device based on semiconductor integrated circuit manufacturing technology. The development of MEMS devices has realized gyro/accelerometer sensors, pressure sensors, and flow sensors that are small enough to be installed in smartphones.
On the other hand, when we look at biological tissues, cells and intracellular microstructures, which are the basic constituent units, are microns or sub microns in size. Therefore MEMS technology is essentially a very powerful tool for researchers who want to manipulate and measure these minute biological components because it matches their scale.
MEMS technologies applied to medicine and life science are called Bio-MEMS, and in recent years, many Bio-MEMS devices and technologies including micro fluidic devices for cell culture, manipulation, and measurement, and lab-on-a-chip devices for chemical reactions and analysis on MEMS devices, have been developed and resulted in very impressive research results.
This Special Issue on “Bio-MEMS” cordially invites you to contribute your papers on a wide range of themes related to Bio-MEMS technology, from fundamental MEMS technology and device development to its applications to experiment and measurement using MEMS devices.

In biological and social systems, a “swarm” refers to a group of individual units that behave as a single intelligent entity. “Swarm behavior,” the collective result of the local interactions among the group members, exhibits what is called “swarm intelligence.” By identifying the design principles of such swarm intelligence, we may be able to create swarm robots that are highly adaptable, fault tolerant, and dimensionally flexible.
For this special issue, we invite papers on topics in which an interdisciplinary approach, including disciplines ranging from technology to biology to the mathematical sciences, for example, is used to elucidate the design principles of swarm intelligence. We believe that such knowledge will lead to transformations in the field of swarm robotics.

As we become a super-aging society, it is essential to maintain and improve the quality of life among the elderly and to counter the young labor force shortage. Such problems are becoming evident in several areas, including not just the manufacturing sector but also the fields of transport/mobility and healthcare/welfare, wherein such situations abound that cannot be solved simply by replacing human workers with robots. In the manufacturing sector, for instance, the transmission of skills and knowledge is threatened as the members of the baby boomer generation who possess the knowledge and experience have reached the age of retirement, even as the younger population is declining. Another example is the provision of care with human warmth at sites of nursing. As we evolve toward Society 5.0, which is represented by a digital transformation and encompasses elements such as digital twins, it will be critical to pioneer a robotic technology that allows robots to work with humans to achieve a prosperous coexistence and create an affluent society. For this special issue, featuring humancentric robotic systems coexisting and working together with humans, we invite researchers to submit papers covering a wide range of topics, including element technologies and operating and evaluation methods.

Autonomous mobility, as exemplified by self-driving cars, autonomous mobile robots, drones, etc., is essential to the acceleration and practical application of transportation services and the automation of delivery, guidance, security, and inspection. Therefore, in recent years, expectations have been building for autonomous mobility to grow as a technology that not only improves the convenience and comfort of transportation and the efficiency of logistics but also leads to solutions to various social problems. Various technological elements are required to ensure the safety and quality of autonomous mobility for safe use. For example, technology is needed to create environmental maps and automatically determine obstacles, based on data acquired by cameras and sensors such as LiDAR. Technologies for planning appropriate routes and controlling robots safely and comfortably are also essential. In this special issue, we call for research papers on the “recognition,” “decision and planning,” and “control” of autonomous mobility in use. We welcome papers on, but not limited to, the following topics: mobile robots, self-driving cars, drones, personal mobility, SLAM, odometry, state estimation, path tracking control, obstacle avoidance, active cruise control, assist control, and attitude control.

The World Robot Challenge (WRC), was a competition in which teams from all over the world competed with their robots in one of the 4 categories: Industrial Robotics, Service Robotics, Disaster Robotics, and Junior. From this competition several research outcomes, practical implementations and new knowledge were created. This special issue of JRM aims at offering an opportunity for participants of the WRC to present their work, and their robots that competed in the WRC, and the learnings from this competition and the outcome for future developments in robotics. Scientific contributions in any of the four categories of the WRC are welcome.
