The development of small applications for engineering calculations is a feasible, useful and interesting work for students of applied mechanics. In order to produce a workable application, it is necessary to have deep knowledge and competences in the field of mechanics, computational methods, information technologies. These knowledge and competences are improved if students are tasked not only to study the behavior of a mechanical system, e.g., a nonlinear dynamical system as described in this paper, but also to develop their own easy-to-use verified object-oriented tool.

IEEE International Workshop on Safety, Security, and Rescue robotics (SSRR)

作者： Andrés Salas-Espinales Ricardo Vázquez-Martín Alfonso García-Cerezo Anthony Mandow Robotics and Mechatronics Group Institute of Mechatronics Engineering and Cyber-physical Systems University of Málaga Spain

This paper evaluates four semantic segmentation models in Search-and-Rescue (SAR) scenarios obtained from ground vehicles. Two base models are used (U-Net and PSPNet) to compare different approaches to semantic segmentation, such as skip connections between encoder and decoder stages and using a pooling pyramid module. The best base model is modified by including two attention mechanisms to analyze their performance and computational cost. We conduct a quantitative and qualitative evaluation using our SAR dataset defining eleven classes in disaster scenarios. The results demonstrate that the attention mechanisms increase model performance while minimally affecting the computation time.

The investigation of resonant circuit parameters influence on the control characteristics behavior in a boost half-wave zero-current switching quasi-resonant converter is presented. The dependences of the control pulses duration and operating frequency as well as electric characteristics under variation of resonant circuit time constant and control pulses duty cycle are established by the numeric simulation and are represented as 3D-surfaces. The dependences of these characteristics under variation of load impedance and control pulses duty cycle are also obtained. The obtained results can be used in the process of developing and constructing a table-based, robust multi-loop or nonlinearity compensated control systems for quasi-resonant converters. © 2023 IEEE.

In the post-COVID erа, there hаs been а growing emphasis on the significance of disinfecting objects individuals come into contаct with. Mobile disinfection robots hаve emerged аs а definitive solution to meet this demаnd. However, inherent issues in their current design mаy pose chаllenges leаding to: continuous virus contamination (there is a risk that mobile UV robots may fail to reach all areas or fully eliminate pathogens, which could allow viruses to survive and subsequently spread infections);increase in the number of disease cases (incomplete disinfection may lead to the persistence of viruses in the environment, thereby increasing the likelihood of disease transmission and the emergence of a greater number of infection cases);illness among medical staff (if the environment in which medical staff operate is not fully disinfected, they may be exposed to the risk of infection with various pathogens, jeopardizing their health and ability to provide adequate medical care);the loss of human lives (inefficiency in disinfection can contribute to the spread of infectious diseases, leading to a higher number of deaths among the population, underscoring the need to address and resolve these issues). This scientific endeаvor аims to outline the primаry chаllenges аssociаted with conventional mobile disinfection robots and introduce a solution through the implementation of аn Аutonomous Mobile Plаtform equipped with а UV Ray Disinfection System. A critical issue identified in conventional mobile disinfection robots pertаins to their inаbility to ensure mаximum efficiency in preventing the spreаd of viruses. This limitаtion is often linked to their stаtic structure аnd the incаpacity to efficiently cover the entire space. Furthermore, the risk of continuous аthe introduction of аn Аutonomous Mobile Plаtform integrated with а UV Rаy Disinfhumection System.

International Conference on mechatronics Technology (ICMT)

作者： Bongsub Song Insung Ju Sunghyun Choi Dongwon Yun Dept. Robotics and Mechatronics Engineering DGIST Daegu South Korea

Recent advances in control units and innovations in battery technology have greatly improved the accessibility of personal mobility, also known as personal mobility. However, most of the personal mobility developed to date utilizes motorized wheels as the primary propulsion source. This approach is limited by the fact that the mobility capability of the device is heavily constrained by the road surface conditions. In this paper, we propose a new form of personal mobility to address these issues. We devised an air cushion-based personal mobility to extend the range of personal mobility devices and reduce their dependence on road conditions. This novel mobility system supports the weight of the system and its occupants through air cushions, and it allows for vector control of the direction of propulsion through individual cushions acting independently. This unique structure is able to overcome the road surface constraints faced by motorized wheel-based personal mobility by floating off the ground. This will enable personal mobility to be effectively utilized in a wider range of environments and situations.

A global health crisis is appeared due to the rapid transmission of the COVID-19 pandemic. According to the World Health Organization (WHO), one of the effective ways to decrease this transmission is wearing masks in crowded places. However, monitoring people by police is a weary and difficult process. Thanks to the improvement in technology and artificial intelligence that make task became easier. In this paper, a simple mask recognition model based on texture and color moments features is proposed. This model is deployed in two stages: first, texture and color moments features from the face image (31 features) are extracted using a hybridization between texture features and color moments features techniques. In order to extract the texture features, the image transformed into Gray Level Co-Occurrence Matrix (GLCM) then 22 statistical metrics were calculated. So as to extract the color moments features, the first, second and third moments have been calculated from each layer of the RGB image. Second, based on the extracted features, the images are classified using a Multi-Layer Perceptron model (MLP). The dataset used in this research consists of 1787 real images with masks and 1918 without masks. The obtained results showed that the accuracy achieved by the proposed model is 90.58% and the time complexity is 6.7379 seconds for training and 0.0023 seconds for prediction. © 2021 IEEE.

The use of Multi-Rotor Aerial Vehicles (MRAVs) in tasks that require physical interaction has been an active research field in the last decade which resulted in an increasing interest in Aerial Manipulators (AMs). This raises many challenges in the modeling, control, perception, and planning of these robots. However, designing and realizing an AM testbed is a complicated multi-disciplinary task, and there is a lack of standardization in the relatively new field of AMs. For this purpose, we introduce Sarax, an open-source hardware and software framework tailored for AMs research and innovation. The software of Sarax is built on top of open-source projects such as the Robot Operating System (ROS) and PX4 Autopilot, while the hardware is designed to be customizable, modular, and easily scalable through parameterized models. We verified and validated the proposed framework through indoor and outdoor experiments. We aim to open the door to accelerate AMs research and innovation, allow researchers and developers to focus on their core contributions, and take AMs technology to a higher readiness level.

This paper focuses on developing a virtually controlled robot by integrating Virtual Reality (VR) and Robot Operating System (ROS). Robots can be used in certain environments where humans cannot be physically present to undertake a task. To increase the safety of humans, controlling a robot virtually is one of the best solutions. This paper shows how the VR-controlled manipulator will help in different fields like hazardous environments, underwater research, and the medical field for surgical operations. Unity 3D is used to develop the virtual environment, and ROS is used for communication with the physical robot. A Virtual environment would be developed where an exact robot (URDF) model can be designed. The interaction with the virtual environment is done with the help of VR headsets and controllers. ROS acts as the communication bridge between virtual and physical robots. A prototype has been developed to be controlled through virtual controllers that can interact through ROS. © 2022 IEEE.
