Human behaviour recognition plays a significant role in early intervention for the cognitive rehabilitation of older people. While existing methods focus on improving third-person vision, human visual attention has been largely ignored in recognition, especially when humans interact with objects. This paper proposes an egocentric behaviour analysis (EBA) based on object relationships using multi-scopic approach. First, we use egocentric vision to extract features from hand posture, object detection, and visual attention movement at the microscopic level. Second, we develop the perception ability to validate the hand-object interaction (HOI) with visual attention at the mesoscopic level. Third, we implement the cognitive ability to describe human activity with multiple object interactions at the macroscopic level. We analyzed Graph Attention Networks (GAT) to evaluate the proposed method for categorizing some activities. The experimental results demonstrate that the GAT can successfully classify related objects with activities. Further research and development are expected to support the robotics application in our living laboratory.

This work proposes two myoelectric control maps based on a DoF-wise synergy algorithm, inspired by human motor control studies. One map, called intuitive, matches control outputs with body movement directions. The second one, named non-intuitive, takes advantage of different synergies contribution to each DoF, without specific correlation to body movement directions. The effectiveness and learning process for the two maps is evaluated through performance metrics in ten able-bodied individuals. The analysis was conducted using a 2-DoFs center-reach-out task and a survey. Results showed equivalent performance and perception for both mappings. However, learning is only visible in subjects that performed better in non-intuitive mapping, that required some familiarization to then exploit its features. Most of the myoelectric control designs use intuitive mappings. Nevertheless, non-intuitive mapping could provide more design flexibility, which can be especially interesting for patients with motor disabilities.

This paper studies SLAM-related work, builds an experimental platform in an actual production environment, and designs experiments to compare several internationally leading commercial SLAM solutions with an open-source SLAM based solution. We also compare localization performance using a retro-reflective landmark system. Their key indicators such as positioning accuracy and repeatability accuracy were evaluated. At the end of the paper, the advantages and disadvantages of each SLAM scheme are comprehensively evaluated from aspects such as performance and cost.

Medical robot research is one of the important research directions in the field of robotics. By searching the Web of Science core collection database, the relevant literature on medical robot research from January 1,2002 to December 31,2022 was retrieved and used as a research sample. Using CiteSpace software combined with VOSviewer and Pajek software for visual analysis, identify and analyze its research status, research hotspots and evolution trends, and predict its development direction. Finally, we found that the research institutions cooperate more, but there are regional constraints. The research hotspots mainly focus on the research of surgical robot, mechanical design and system development, and the deep integration of robot and medical treatment. In recent years, the keywords of related literature in this field mainly include Artificial intelligence, human-computer interaction, software robots, care and so on. Research on telemedicine, AI assistance, and flexible wearables are some of the future development directions in this field.

The pneumatic soft manipulator is made of flexible materials, which has the characteristics of strong environmental adaptability, safe human-machine interaction, etc. In practice, the pneumatic soft manipulator has more and more applications in medical rehabilitation, aquaculture, pipeline maintenance, search and rescue work, etc. In recent years, the demand for pneumatic soft manipulators has increased, and higher requirements have been put forward for their flexibility and operation accuracy. However, due to the large deformation nonlinear characteristics of the pneumatic soft manipulator, its kinematic modeling is difficult. Considering this fact, this paper focuses on the kinematic modeling and trajectory planning for the pneumatic soft manipulator with three chambers. Firstly, we obtain the forward kinematic and inverse kinematic models of the pneumatic soft manipulator with three chambers through rigorous analysis and mathematical derivation. After that, based on the kinematic model, we propose a trajectory planning method for the pneumatic soft manipulator with three chambers. Finally, simulation results are given to test the satisfactory performance of the proposed method.

This paper reports the progress of an ongoing project "Emergency Evacuation System for Disabilities in Wheelchair" sponsored by Engineering Projects in Community Service (EPICS) of IEEE. The project aims to develop an advanced mechatronic system that will be used to evacuate a disabled in a wheelchair from a high-rise building with the minimal assistances from caregivers. In this paper, the needs to develop such a system are discussed thoroughly, existing evacuation techniques are investigated to identify their limitations, a new evacuation system is conceived to enhance safety, flexibility, and efficiency of existing techniques. The project also explores a new way to support students' collaborations in designing a complex mechatronic system effectively. Model-Based System Engineering (MBSE) is adopted in designing key system components with minimized couplings with others, and the case study development has evidenced the systematism and effectiveness of MBSE in dealing with couplings, complexity, and scalability of complex mechatronic systems.
