Robotics, mechatronics, and digital technologies are actively being used in sports, health care, and exercise. Additionally, advancements in AI and robotics are expected to lead to even more innovative applications. Robotics technology plays a significant role in sports and exercise training. There is a growing interest in technology that enables training robots to monitor individual movement and form, providing feedback to the user and facilitating effective training. The combination of biosensor technology and digital technology is enhancing performance and health monitoring. Real-time data collection using wearable devices and smart sensors allows for measuring exercise performance and analyzing biometric data. Systems are also being developed that utilize AI and machine learning to analyze individual data and provide information to enhance performance and prevent injuries. VR and AR are offering groundbreaking experiences in the field of sports and exercise, with various applications in development, including training simulations, realistic recreations of competitive events, visual performance analysis, and virtual coaches for training instructions. In this special issue, we invite papers on the research and development of robotics, mechatronics, and digital technologies and systems in sports, health care, and exercise. We also welcome papers discussing the social implementation of these systems.
