Aplicación de algoritmos de navegación autónoma en entornos estáticos desconocidos para el robot TurtleBot3 sobre ROS
(Universidad Distrital Francisco José de Caldas) Pachón Márquez, Daniela Esperanza; Jacinto Gómez , Edwar; Jacinto Gómez, Edwar [0000-0003-4038-8137]
This project addresses the autonomous navigation challenge for a TurtleBot3 robot in unknown static environments. The goal is to implement a series of navigation algorithms based on SLAM over ROS that generate maps and navigation tasks. The proposed solution integrates a custom ROS package that incorporates 360° LiDAR data processing. The system will run on the TurtleBot3 Burger platform with Raspberry Pi 4, employing low computational cost algorithms (Hector SLAM, Gmapping) and a ROS stack for the move_base algorithm. It will be validated in three real environments (classroom, hallway, open space) with localization and coverage metrics.
Propuesta de implementación del mantenimiento productivo total (tpm) y el oee en la mejora de la eficiencia operativa y la reducción de tiempos de inactividad para la empresa minipak s.a.s.
(Universidad Distrital Francisco Jose de Caldas) Mendez Muñoz , Cristian Camilo; Santos Salinas, Cristian Sebastian; Rodriguez Florian, Roman Leonardo; 0009-0008-2693-6890
This research arises from the need to improve operational efficiency and reduce downtime in the Rotogravure area of the company Minipak S.A.S, in which constant equipment failures and low participation of employees in maintenance activities are evident. The main objective is to develop a proposal based on Total Productive Maintenance (TPM) and the Overall Equipment Effectiveness (OEE) indicator, to optimize resources, reduce losses and increase operational availability. A descriptive methodology with a quantitative approach was developed, which included the current diagnosis of the plant, the analysis of operational data, the identification of failure times, and the measurement of OEE. The results show a low level of overall efficiency, mainly associated with unplanned stoppages and little participation of personnel in the care of the equipment. Finally, a proposal is presented for the implementation of TPM the use of OEE to identify critical points, reduce losses and increase performance and quality in the rotogravure processes.
Desarrollo de una aplicación móvil usando la metodología scrum para realizar un registro del estado de seguridad en los que se encuentran los cajeros automáticos
Parra Contreras, Lisbeth Judyana; Torres Agudelo, Wilmer Fabian; Gómez, Edwar Jacinto; 0000-0003-4038-8137
In this paper a solution is proposed to support the security of ATMs, since there has been a high rate of citizens who constantly distrust ATMs, due to their repeated incidents and developments in the face of acts of vandalism, due to this reason and with the objective of providing a contribution to the surveillance companies, a mobile application is presented which allows obtaining information of the inspections of the drivers online, being more accurate and with photographic support, this information can be visualized on a platform web anywhere in the city. Additionally, there is the online tracking or location of users who use the application and thus request assistance from the different ATMs where an inspection is desired, generating it from the web platform and executed from the mobile application. The records sent from different parts of the city of Bogotá and surrounding areas are reflected along with the times of reception and response of the requests sent
Ciberdefensa Abierta: El Ciclo de la Inteligencia de Amenazas con Software Libre
Lozano Arana, Eduard David; Ferro Escobar, Roberto
This article establishes the fundamental guidelines for adopting projects developed within free and open‑source software communities in corporate environments, with an emphasis on their application in cybersecurity systems. Its aim is to highlight the potential of these solutions to build secure, legitimate, and scalable ecosystems capable of integrating multiple layers of protection and threat intelligence. It examines the strategic impact of free software on modern cyber defense, addressing the technical and legal implications associated with the various available licenses. The article also clarifies the differences between free software and proprietary software, emphasizing that access to source code does not necessarily imply zero cost or the absence of restrictions. Additionally, it categorizes the main types of projects found in open‑source communities, assessing their ability to integrate with enterprise security standards and regulatory frameworks. This approach seeks to encourage the informed adoption of open solutions, promoting sustainable and auditable practices in digital risk management.
RIS para Mejorar la Conectividad Inalámbrica en Bogotá
Moreno Reinel, Jahir Leonardo; Ferro Escobar, Roberto
Electromagnetic waves used in mobile services and next-generation networks face significant propagation constraints in urban environments due to high attenuation and limited building penetration. In cities, these limitations are compounded by sparse, antenna density, spectrum congestion, and geographic factors, leading to areas of poor connectivity and deepening the digital divide. This study examines connectivity quality in Bogotá by analyzing data sources such as user-reported reception and proposes the use of Reconfigurable Intelligent Surfaces (RIS) to create intelligent radio environments, drawing on the predominant literature on this technology. RIS are programmable metasurfaces capable of manipulating electromagnetic waves to increase information capacity and optimize the wireless channel. We outline potential deployment scenarios and the challenges relative to traditional designs currently implemented in the capital.
