This book is mainly about the research on human-motion-based teleoperation and intelligent human-robot interaction technologies. With the development of motion capture and human-robot interaction technologies, human-motion-based teleoperation systems have become a research hotspot in the field. This book conducts research in four aspects: single-arm motion mapping, dual-arm motion mapping, whole-body motion mapping, and reliable communication for teleoperation. Moreover, two application cases are introduced to validate the usability of the human motion mapping strategies from the perspective of remote homecare and remote medical assistance in Healthcare 4.0. Practitioners in fields such as robotics, human-robot interaction, and remote operations can all draw inspiration from this book.
