Analyzing time-series changes of the contact surface by touching is important to elucidate the touching skills of Humanitude as one of the pervasive multimodal comprehensive care methodologies. For the analysis, there is a frustrated total internal reflection (FTIR) method to capture contact surfaces on a transparent flat plate by a camera. However, this conventional flat plate is far from the actual surfaces of care receivers because the surfaces of humans consist of curved shapes. In this paper, we propose an FTIR sensing system using a transparent curved plate to capture more ideal contact states with a surface shape more similar to the human body. We collect the contact surface data of the beginning of touching motions by Humanitude experts and novices using the FTIR sensing system with the curved and flat plates. Then, we compare the data by the experts and novices in terms of time-series contact areas and the quantitative indices and subjective evaluation and discuss the analysis results. Through these experiments, we confirm that the proposed system has the potential for the novices to perform more correctly the beginning of Humanitude's touching motions. © 2024 IEEE.

The rapid development of computer vision makes human-computer interaction possible and has a wide application prospect. Since the discovery of the first case of COVID-19, the global fight against the epidemic has begun. In addition to various studies and findings by medical and health care experts, people's daily behaviors have also become key to combating the epidemic. In China, the government has taken active and effective measures of isolation and closure, as well as the active cooperation of the general public, such as it is unnecessary to stay indoors and wear masks. China, as the country with the first outbreak of the epidemic, has now become the benchmark country of epidemic prevention in the world. Of course, it is not enough for people to wear masks consciously. Wearing masks in all kinds of public places still needs supervision. In this process, this paper proposes to replace manual inspection with a deep learning method and use YOLOV5, the most powerful objection detection algorithm at present, to better apply it in the actual environment, especially in the supervision of wearing masks in public places. The experimental results show that the algorithm proposed in this paper can effectively recognize face masks and realize the effective monitoring of personnel. © 2020 IEEE.

At present, Chinese traditional physiotherapy is more and more trusted and valued by people, among which moxibustion is a very effective treatment. In order to improve the efficiency of human-computer interaction and help physiotherapists to use robots to replace human power, this paper proposes a visual based robot arm trajectory teaching method. The physiotherapy staff only needs to use an optical marker to demonstrate the therapeutic trajectory on the patient's back, and the robotic arm can pick up the expected trajectory and repeat the same work. We use LK optical flow algorithm to obtain marker's motion trajectory, and then smoothen the trajectory through SG filter, which is more executable for robot arm. Finally, we design an experiment and simulate it on MATLAB to obtain the accuracy of the trajectory and the results is impressive.

This paper presents a soft actuator inspired by origami and a tunable strain limiting layer, which is proposed for reconfigurable soft robotic grasping. Main structure of the actuator is based on Miura origami which generates extension under pressurized air while a limiting layer with tunable length enables the actuator with different motion patterns. By driving the limiting layer through a servo motor, the range of motion and trajectory of the actuator can be pre-programed and the gripper’s grasping range will be affected accordingly. This paper discusses the design, fabrication, analysis and experimental verification of the actuator. Then grasping performance of the gripper under objects of different shapes, sizes, and weights is experimentally evaluated. The reconfigurable soft gripper can be applied as an end-effector to accomplish adaptive grasping tasks with various targets.

Minimally invasive vascular interventional surgery has become one of the main clinical modalities for the treatment of cardiovascular diseases due to its advantages of small intraoperative incisions, precise localization of lesions, and rapid postoperative healing. Based on the drawbacks of low operational precision and excessive radiation exposure of physicians in current vascular interventional procedures, this paper proposes a master-slave teleoperated vascular interventional surgery robotic system to assist physicians in human-machine collaborative interventional procedures. Particularly, the implementation of the system's surgical actions of push-pull and twist guidewire is presented, including hardware construction and driver development. Further, experiments are conducted to test and analyze the performance of the robotic control system. The experimental results verify that the robotic system has good master-slave following and high system positioning accuracy. Finally, the feasibility and reliability of the robotic system for delivering guidewires to perform interventional procedures were verified by robot-vascular model experiments. © 2021 IEEE.

The investigation focused on microstructural changes and hot corrosion behaviour in various salt environments (Na2SO4+25 wt% K2SO4 and Na2SO4+25 wt% NaCl) at 900 °C of NiCoCrAlYSi laser cladding coatings before and after high-current pulsed electron beam (HCPEB) irradiation. HCPEB treatment effectively eliminated imperfections like micropores and elemental segregation, creating a remelted layer characterized by a high-density dislocations and nanostructures. The irradiated impacts including polishing, purification, composition homogenization, and grain refinement facilitated the development and self-repair of a compact and tenacious oxide scale. This enhanced oxide layer effectively mitigates extensive corrosive media erosion. The utilization of HCPEB treatment has shown significant potential in enhancing the hot corrosion resistance of NiCoCrAlYSi laser claddings. © 2023, The Authors. All rights reserved.

Aiming at the problem that the conventional target recognition algorithm is highly dependent on light and has a poor fruit recognition effect in low light and dark environments, this paper proposes a three-dimensional fruit recognition method based on PointNet++. First, a depth camera is used to obtain point clouds to construct a dataset, and then the network is trained using the dataset. Finally, the fruit point cloud is recognized by the trained network. The experimental results show that the PointNet++ algorithm can recognize both unoccluded and partially occluded fruit point clouds, and the IoU of the predicted and real results are 0.92 and 0.89, respectively, which meets the actual production requirements.

Mooring location has become increasingly important with the rapid development and utilization of marine resources. The mooring system of the underwater mobile robot is required to be efficient and intelligent. This paper proposes a novel anchoring robot by imitating the excellent inhabitation functions and physiological structure of the razor clam. This bio-inspired robot can autonomously dig holes, anchor, and detach to improve the efficiency of mooring location in marine operations. Specifically, the axe foot of the robot plays an important role in these movements. It contains a screw-cone drill and two soft parts. The screw-cone drill is the main forced part while the robot is in the digging state and the rationality of drill design is proved by mechanics analysis. Moreover, the soft part, which is connected with the upper end of the drill, is analyzed to show the capability of obstacle avoidance. The rationality of the structural design and a good submarine anchoring function of the axe foot are verified by the above analysis.
