Item Desarrollo de un dispositivo biomecatrónico adaptable al miembro superior humano para ejercicios funcionales de acondicionamiento físico(Universidad Santiago de Cali, 2019) Tovar Sánchez, Javier David; Franco Vargas, Sergio Alejandro; Arcos Hurtado, Edgar Francisco (Director)Recognizing the importance of technology in the different processes of scientific, economic and social research, and putting it at the service of man in favor of improving their health conditions, has been a constant throughout history. Today these advanced technologies are offered only in specialized places for such purposes, which limits users in time and space to make use of them, not allowing the integration of such technologies to their daily lives and facilitate their living conditions. Another relevant aspect is the high costs associated with these technologies, a factor that prevents people who do not have economic resources from accessing them. Taking into account these aspects, and in order to reach a larger population, we developed a biomechatronic device adaptable to the human upper limb with double functionality, the first is the prevention of diseases associated with sedentary lifestyle through the enhancement of functional exercises of physical conditioning, focusing mainly on strengthening and bodybuilding in the early stages after an injury, the second is rehabilitation for people with mobility difficulties in the upper limb, either by natural causes or accidental, providing in a single portable device the ability to prevent and rehabilitate diseases and / or injuries of the upper limb. The first is the ability to prevent and rehabilitate diseases and / or injuries of the upper limb. In the process of developing the device, stages of planning, generation and evaluation of concepts, detailed design, construction, tests and adjustments were carried out to finally arrive at the prototype that managed to satisfactorily supply the bodybuilding and rehabilitation phases, the latter being the main axis, given the technical specifications required for bodybuilding in active users.Item Desarrollo de una órtesis para rehabilitación de hombro con dos grados de libertad de uso domiciliario(Universidad Santiago de Cali, 2024) Valdés Olivera, Joseph Alejandro; Bermeo Varón, Leonardo Antonio (Director); Arcos Hurtado, Edgar Francisco (Director)Limitations in upper limb movement due to pathologies or accidents can significantly impact a person's daily life, affecting their social, economic, and professional activities. This underscores the importance of rehabilitation, which, through consistent therapies, can effectively aid in the recovery process. However, traditional rehabilitation often relies on large supportive devices, necessitating visits to care centers. Unfortunately, inconsistent attendance can lead to slow or even nonexistent progress. To address this, portable active orthoses have emerged as a potential solution, offering the possibility of faster recovery. In this study, an additional degree of freedom (flexion extension of the shoulder) was integrated into an orthosis previously developed at the University of Santiago de Cali, tailored for upper limb rehabilitation in individuals with limited shoulder movement. The implementation involved redesigning the device, updating electronic components for improved ergonomics, and incorporating a linear motor. The device underwent evaluation with 15 participants performing shoulder flexion-extension movements from rest to 70, yielding an acceptability rating of 75.6 out of 100 using the system usability method.Item Desarrollo mecánico de una prótesis para desarticulación de codo(Universidad Santiago de Cali, 2021) Salazar Rojas, Michael Alexander; Sánchez Montehermoso, Melissa ; Arcos Hurtado, Edgar Francisco (Director); Bermeo Varón, Leonardo Antonio (Director)Amputations are a procedure in which a limb is separated from the body. As a result of this process, you have a residual limb or stump. Commonly, amputations are the result of traffic accidents or work-related accidents, mostly in the agricultural sector. When an individual has undergone an amputation, his limb can be replaced by a prosthesis that will allow you to perform functions that you have lost in some way. In this work was realized a development of an active prosthesis, which will help the user to perform movements that facilitate the development of their daily activities, for example, brushing their teeth, putting food in their mouth, carrying or directing some kind as an object. These activities can be carried out because the prosthesis can perform movements such as supination and pronation of the elbow, as well as flexion (140º) and extension of the same. The design of the prosthesis has a clamp or gripper; a grip element, which will allow the user to grasp or hold objects regardless of their shape and that meet an average weight of 500gr. The clamp has a maximum (10 cm) and minimum (0 cm) opening limit. The prosthesis is designed with materials that allow its durability, materials resistant to prolonged use and rigid to execute the movements correctly, but at the same time they are light materials that do not generate a weight disproportionate to that which the patient can support, as this can cause another type of inconveniences in the health of the user. Gears were used for the transmission system and electric actuators were used for the actuation system.Item Sistema en línea para el monitoreo de humedad y temperatura en el laboratorio de metrología de una clínica de la ciudad de Cali(Universidad Santiago de Cali, 2025) Rojas Perdomo, Stefany; Marroquin Torres, Angie Sthefany; Mamian Homen, Vladimir; Arcos Hurtado, Edgar Francisco (Director)Isothermal enclosures are medical and industrial equipment designed to condition a closed space to maintain appropriate temperature and humidity levels. These enclosures may sometimes fail due to manufacturing defects, lack of maintenance, material wear, battery support issues, or human error. If not detected in time, such failures can compromise environmental conditions, especially within the climate chamber, and negatively impact processes such as the calibration of thermo-hygrometers. To address this issue, this work presents the development of an online measurement system that enables real-time monitoring of temperature and humidity conditions in a specific laboratory. This technological solution integrates a system based on an ESP32 microcontroller and humidity and temperature sensors, with data stored in the cloud using InfluxDB and visualized through the Grafana platform. Four monitoring devices were developed and deployed in the equipment room, the mass area, the pressure area, and the temperature and humidity area (including the climate chamber). Over a one-month evaluation period, more than 43,200 records per sensor were collected (one sample per minute), which allowed for the identification of out-of-range behaviors during at least four simulated failure events. The system demonstrated a reduction in the average failure detection time of over 85% compared to manual verification, thus improving response capacity to critical variations. Additionally, energy autonomy tests were conducted by simulating a power outage, during which the devices continued to operate normally using a rechargeable battery for a period of three hours. The results indicate that the system not only significantly reduces response time to failures but also optimizes calibration processes, enables traceability of environmental conditions, and ensures continuous monitoring in compliance with ISO/IEC 17025:2017.
