The virtual-real interaction system design and interaction characteristics research of an ankle rehabilitation robot based on digital twin.
BackgroundIn recent years, the large-scale epidemics and the increasing demand for rehabilitation generated a demand for remote rehabilitation, while digital twin provided technical support for home-based rehabilitation.ObjectiveIn order to monitor the operation status of rehabilitation robot and make dynamic adjustments, a virtual-real interaction system for an ankle rehabilitation robot (VRIS-ARR) is designed based on the digital twin theory, and its virtual-real interaction characteristics is researched.MethodsThe VRIS-ARR is consisted of physical layer, communication layer, virtual layer and application layer, and is designed by the application of software tools such as 3ds Max, Unity 3D, C#, Python. The database technology and multi-threaded development method are applied to realize the virtual-real interaction function of the system.ResultsThe performance and function experiments of the VRIS-ARR are carried out, and the system has the characteristics of strong virtual-real interaction, which can work smoothly with high control accuracy and without obvious delay.ConclusionThe experimental results indicate that the developed VRIS-ARR is very reliable between the ankle rehabilitation robot and the host computer.
期刊介绍：
Technology and Health Care is intended to serve as a forum for the presentation of original articles and technical notes, observing rigorous scientific standards. Furthermore, upon invitation, reviews, tutorials, discussion papers and minisymposia are featured. The main focus of THC is related to the overlapping areas of engineering and medicine. The following types of contributions are considered:
1.Original articles: New concepts, procedures and devices associated with the use of technology in medical research and clinical practice are presented to a readership with a widespread background in engineering and/or medicine. In particular, the clinical benefit deriving from the application of engineering methods and devices in clinical medicine should be demonstrated. Typically, full length original contributions have a length of 4000 words, thereby taking duly into account figures and tables.
2.Technical Notes and Short Communications: Technical Notes relate to novel technical developments with relevance for clinical medicine. In Short Communications, clinical applications are shortly described. 3.Both Technical Notes and Short Communications typically have a length of 1500 words.
Reviews and Tutorials (upon invitation only): Tutorial and educational articles for persons with a primarily medical background on principles of engineering with particular significance for biomedical applications and vice versa are presented. The Editorial Board is responsible for the selection of topics.
4.Minisymposia (upon invitation only): Under the leadership of a Special Editor, controversial or important issues relating to health care are highlighted and discussed by various authors.
5.Letters to the Editors: Discussions or short statements (not indexed).
