    A Remote Monitoring System of Potato Growing Conditions in urban crops
    (Universidad Católica San Pablo, 2025) Calla Guzman, Nathali Muriel; Barrios Aranibar, Dennis
    The text addresses the impact of overpopulation, climate change, and rising food prices on food security, highlighting urban agriculture as an innovative solution. While this method allows for food production in small spaces, it demands time and commitment, which can be challenging for busy individuals. Agriculture 4.0 employs satellites, robotics, and AI to optimize crop monitoring, conserve water, and eliminate insecticides. The proposed system includes data collection, cloud transmission, and userfriendly interpretation, featuring humidity and temperature sensors linked to an ESP32 microcontroller, a real-time database, and a web platform for control. Results indicate improved care and growth of potato plants by maintaining optimal conditions. The system is user-friendly, scalable, and future research aims to integrate mobile robots for broader applications.

    An approach of social navigation based on proxemics for crowded environments of humans and robots
    (MDPI, 2021) Daza Guardamino, Marcos Julio; Barrios Aranibar, Dennis
    Nowadays, mobile robots are playing an important role in different areas of science, industry, academia and even in everyday life. In this sense, their abilities and behaviours become increasingly complex. In particular, in indoor environments, such as hospitals, schools, banks and museums, where the robot coincides with people and other robots, its movement and navigation must be programmed and adapted to robot–robot and human–robot interactions. However, existing approaches are focused either on multi-robot navigation (robot–robot interaction) or social navigation with human presence (human–robot interaction), neglecting the integration of both approaches. Proxemic interaction is recently being used in this domain of research, to improve Human–Robot Interaction (HRI). In this context, we propose an autonomous navigation approach for mobile robots in indoor environments, based on the principles of proxemic theory, integrated with classical navigation algorithms, such as ORCA, Social Momentum, and A*. With this novel approach, the mobile robot adapts its behaviour, by analysing the proximity of people to each other, with respect to it, and with respect to other robots to decide and plan its respective navigation, while showing acceptable social behaviours in presence of humans. We describe our proposed approach and show how proxemics and the classical navigation algorithms are combined to provide an effective navigation, while respecting social human distances. To show the suitability of our approach, we simulate several situations of coexistence of robots and humans, demonstrating an effective social navigation.

    An approach to improve simultaneous localization and mapping in human populated environments
    (IEEE, 2021) Inofuente Colque, Kevin Adier; Barrios Aranibar, Dennis
    One task that autonomous mobile robots have to perform in indoor spaces is to construct the map of their environment and report their location and orientation. This process is called Simultaneous Localization and Mapping (SLAM). To do so, robots extract data through their sensors. However, in dynamic indoor environments, moving objects induce the SLAM process to collapse or diverge. Moving objects should not be taken into account to generate the map and the occlusions that they generate should be solved. In this work, we propose a robust and flexible approach for SLAM algorithms to perform better in human populated environments; by integrating a filtering scheme that manages moving and static objects. To illustrate the suitability of our approach, we implement Gmapping, as the classical SLAM algorithm, and RANSAC as the filter. Nevertheless, any other SLAM algorithm and filter can be implemented. The simulation tests have been carried out using three museum environments, which the robot can face in real life. Through the results obtained, it is possible to conclude that the proposed approach is efficient in managing the sensor data, filtering the outliers, and thus removing dynamic objects from the map.
