In the last few decades, solar panel cleaning robots (SPCR) have been widely used for sanitizing photovoltaic (PV) panels as an effective solution for ensuring PV efficiency. However, the dynamic load generated by the SPCR during operation might have a negative impact on PV panels. To reduce these effects, this paper presents the utilization of ANSYS software to simulate multiple scenarios involving the impact of SPCR on PV panels. The simulation scenarios provided in the paper are derived from the typical movements of SPCR observed during practical operations. The simulation results show the deformation process of PV panels, and a second-order polynomial is established to describe the deformed amplitude along the centerline of PV panels. This second-order polynomial contributes to the design process of a damper system for SPCR aiming to reduce the influence of SPCR on PV panels. Moreover, the experiments are conducted to examine the correlation between the results of the simulation and the experiment., Comment: 8 pages, 8 figures, The 4th International Conference on Applied Convergence Engineering (ICACE 2023)

In the COVID-19 period, the number of deaths has increased every day around the world. The pandemic has impacted the life and economy. Especially, there is a shortage in medical including a lack of technology, facility and equipment. One of those, ventilators are the essential equipment that does not provide enough requirements for the hospital. A ventilator is an essential unit in hospitals because it seems to be the first step to protect the life of the patient getting sick. Some low-income countries aim to make a simple ventilator using locally available and low-cost materials for primary care and palliative care. One of the simple principles of ventilators is to adopt an artificial manual breath unit (AMBU) bag with paddles. Unfortunately, the squeezing angle of paddles is not proportional to the exhaust air volume from the AMBU bag. This paper analyzes the character of the squeezing angle of the paddles and the exhaust air volume of the adult AMBU bag through experiments. The result can be used to control the squeezing angle through a DC motor mounted with paddles to obtain the desired air volume., Comment: 11 pages, 11 figures, submitted to The 17th International Conference on Intelligent Unmanned Systems (ICIUS 2021)

This paper is described the massage robot working and acting on the body back with pressure by automation. The massage robot will offer a more affordable and user-friendly alternative with the same benefits as the massage by the therapist. The study investigated the role of effective massage head of robot in the interaction between human and robot. Through a process of design and controlled user evaluation, we examined the cooperation between robot and human as well as the physical influence of affective contact. The system scans to perceive and give motions and touch through elastic and vibration contact. We detail the design of the massage robot, which imitates massage experts with complex operations, then was enhanced through intelligent autonomous.

In the fast-paced modern life, everyone needs some time to relax. A good way to do it is through massage, it helps to get relief from body pain or eases stress and anxiety and then helps to lower blood pressure and more and more other health benefits. Nowadays, you can enjoy the professional massage machine without a therapist. The point and massage therapy machine will offer a more affordable and user-friendly alternative with the same benefits as the massage by the therapist. In this paper, a study of point and massage therapy using image processing is described and the information from image data also extracted to control automation machine or robot massage. After extracting the points from scanning images by a camera, the massage therapy trajectories were sent to master computer for intelligent control, the massage lines would be mapped to support for massage processes. It is not only suitable for every single person and save the time of but also be easy to be data retrieval and not depend on professional experts. This study is based on actual demand so practical application is very wide. Moreover, it will solve the time-consuming problem of experts. In addition to, with the automation, the quality of massage therapy is much higher and the process will be continuous.

This paper discusses the development of a service robot for translating spoken language text into signed languages and vice versa. The motivation for our study is the improvement of accessibility to public information announcements for deaf and less hearing people. The robot can translate Vietnamese sign language into speech and recognize Vietnamese/English speech to suitable gesture/sign language. The paper describes the use of service robot in a sign language machine translation system. Several sign language visualization methods were evaluated on the robot. In order to perform this study a machine translation service robot that uses display screen on robot as service-delivery device was developed as well as a 3D avatar. It was concluded that service robot are suitable service-delivery platforms for sign language machine translation systems.
