It's Your Fault! The Influence of Roboldo, a Social Robot, on Human Guilt and Shame in an Interactive Game
type: item
description: This research investigates the ethical consequences of human interaction with Roboldo, a cost-effective emotional robot assembled using low-cost hardware. Grounded in theories such as Computers as Social Actors and Robots as Persuasive Agents, the study examines the influence of blame attribution for mistakes on participants' sense of guilt and shame, specifically within a memory card game. Participants filled out questionnaires pre- and post-interaction with Roboldo, evaluating their initial perceptions of the robot and their levels of guilt and shame under two distinct conditions: one where Roboldo faults the participant for its errors, and another where it faults its developer. The findings reveal no significant differences in levels of guilt and shame between conditions. Additionally, no substantial changes were observed in overall perceptions of the robot's friendliness or effectiveness. These results underscore the complexity of emotional responses in human-robot interactions and emphasize the importance of ethical considerations in robot design.

Integration of BERT Models in NAO Robot for Library Assistance
type: item
description: Uuman-Robot Interaction has evolved significantly with advancements in artificial intelligence (AI) and natural language processing (NLP). This paper investigates the BERT Model and pre-trained sub-models to develop a tool that enable more natural dialogues among social robots and humans. To this end, the NAO robot from SoftBank Robotics was designed to function as a library assistant for the student community. The proposed system integrates the Google Speech Recognition API for voice recognition, transcribing the user's speech into text. Moreover using BERT model and pre-trained sub-models for natural language understanding, the system interprets the user's intent and responds appropriately. Using its Speech Synthesis system, the NAO robot interacts with users through audio, simulating a real conversation. Several experiments were conducted for demonstrating that this setup facilitates user communication, serving as an efficient and accessible intermediary for providing library information.

What is the Comfort Distance for a Human and a Collaborative Industrial Robot Interaction?
type: item
description: Humans interact with each other considering a complex mechanism of analysis defined by the fusion of cultural factors with a set of non-verbal factors such as kinesics, haptics and visual cues. This behavior is termed proxemics, with interpersonal distance being its most expressive signal. When interacting with robotic agents, proxemic behavior must also be considered while respecting the human need to maintain a comfortable distance. This study explores the hypothesis that the comfort distance decreases as there is a common interest activity underway. To validate this hypothesis, a human-robot interaction experiment was conducted where the common interest is achieved through a card game. In addition to the quantitative data, such as the robot's distance, the experiment also generates qualitative data through subjects' responses to a questionnaire about their impressions of the interaction. The analysis of the experiment results is of particular interest in industrial plants where the use of collaborative mobile robots (cobots) represents a growing demand in the sector.

RoboSign: Improving Interaction Between Service-Robot and Hearing Impairments People
type: item
description: Service robots assist humans in routine activities such as domestic tasks. Their interaction with humans, e.g., during communication, is commonly done through voice recognition functionalities. However, voice interaction limits robot usage, making it inaccessible to hearing-impaired people. This paper presents RoboSign, an interaction solution between a service robot and people with hearing impairments through command recognition in Brazilian Sign language (Libras). RoboSign includes a simplified dataset from scratch for a computer with low computational power, training a recurrent neural network model using MediaPipe Landmark Detector and Long ShortTerm Memory (LSTM) to perform signal recognition. The model was validated during training with unknown data, reaching 99% average accuracy, and evaluated in real-time using a camera, reaching 85% average accuracy. These results demonstrate that it is possible to perform human-robot interaction through Libras recognition with considerable accuracy without high computational cost due to simplified data collection and the LSTM algorithm for network training.

LLM Text Generation for Service Robot Context
type: item
description: Service robots are designed to perform useful activities for humans or other machines, such as cleaning a house, providing guidance, or cooking. To perform these activities, robots must be increasingly autonomous and capable of executing physical and cognitive tasks. Such skills involve human-robot interaction, where humans give a specific command, and the robot performs the task. In this scenario, voice recognition and detection tools can ensure communication through natural language. However, obtaining comprehensive and contextualized answers to specific questions or topics becomes challenging for the robot, which relies on static and pre-existing information to generate rigid and repetitive responses. This limitation hinders the creation of a more natural and intuitive dialogue between humans and machines. This paper proposes the LLP4ServiceRobot solution, which uses fine-tuned large language models to generate more dynamic texts and responses. The development methodology involves selecting large language models, fine-tuning them, and training them for text generation and question-answering tasks. We validated our model using two performance metrics: the Fl-Score, for the question-answering model; and ROUGE, for the text generation model. Results showed that the question-answering model achieved an F'l-Score of 52%, while the text generation model achieved a ROUGE-l score of 67%. Additionally, an experiment was conducted to evaluate the Question Answering (QA) model. Results showed that the model could correctly answer 60 % of the questions in a test dataset. The proposed model will be used in the service robot BILL, part of the RoboCup@Home league research at ACSO - the Center for Research in Computer Architecture, Intelligent Systems, and Robotics at the State University of Bahia - UNEB.

Dynamic Safety Zones for Industrial Robots: A Fuzzy Logic and Computer Vision Approach
type: item
description: This research focuses on integrating a robotic manipulator in shared workspaces within the framework of Indus-try 4.0 for Human-Robot Collaboration (HRC). The primary objective is to implement a safe strategy by employing a fuzzy-speed controller to enhance the mobile robot's movements near machinery. This strategy utilizes two cameras: one mounted on the ceiling of the industrial environment and another on the robot itself, called an eye-in-hand camera. The You Only Look Once Version 3 (YOLOv3) Convolutional Neural Network (CNN) detects the obstacles in the environment and identifies the target objects. Simulations were conducted using Gazebo software along with a Robot Operating System (ROS) to determine the effectiveness of the proposed approach in ensuring safe robot movements while accurately reaching target positions by dynamically adjusting velocity within the defined danger zone.

Analysis of the Effect of Marine Currents on an Aerial-Underwater Vehicle
type: item
description: Aerial-underwater vehicles present control challenges in both aerial and underwater environments, so obtaining a model for simulating the current effects experienced by these vehicles in both environments provides an important theoretical basis for analyzing dynamic behavior in closed-loop control. This article proposes the analysis of an aerial-underwater hybrid vehicle while adding the effects of ocean currents as perturbations. In this regard, it is intended to explore two numerical simulation scenarios: in the first scenario, the vehicle performs a mission in an underwater environment without the presence of ocean currents, and in the second scenario, with the inclusion of the effect of ocean currents under the same mission conditions, to illustrate the difference in the vehicle's behavior.

Deep Reinforcement Learning Applied for Threat Engagement by Loyal Wingmen Drones
type: item
description: This study explores using Loyal Wingmen drones in counter- UAV systems to detect and neutralize multiple aerial threats cooperatively. We employ Curriculum Learning and Bayesian Optimization to enhance the Proximal Policy Optimization algorithm, which trains a Deep Neural Network to perform high-level decision-making. The effectiveness of this network is assessed in simulations that pit it against an increasing number of Loitering Munitions, with a comparative analysis of a Behavior Tree agent. A key finding is the effective deployment of simulated LiDAR technology for dynamic multi-target detection, which surpasses traditional systems limited to observing a fixed number of entities.

Trajectory of Humanoid Robots with the Unscented Kalman Filter
type: item
description: In this paper, the integration of the Unscented Kalman Filter (UKF) with gait control for humanoid robot navigation was explored, specifically for the NAO robot. The UKF improves the accuracy of state estimation by processing nonlinear transformations, while gait control adjusts the robot's trajectory using real-time feedback from landmarks detected through computer vision. Experimental results demonstrate that this approach significantly reduces trajectory deviations, leading to improved navigation accuracy and system robustness. This method has potential applications in autonomous robotic systems.

Attitude Control and Simulation of a low Orbit Nanosatellite
type: item
description: Nanosatellites have been objects of research and application in recent years due to the accessibility promoted by the standardization of components and structures. The various applications of this type of device require well-determined and controlled behavior. In this work, a nanosatellite simulation platform provided by Matlab/Simulink was extended and applied to validate closed-loop attitude control techniques using a set of reaction wheels as actuators for low-orbit operation. The attitude of a small satellite was controlled from an unfavorable initial condition, in a movement known as detumbling. The implemented PID controller showed good results in regulating the satellite's orientation angles in low orbit, correcting and maintaining its pointing towards the Earth, without saturating the set of reaction wheels.

Teach and Repeat for Path Planning Using Bézier Curves
type: item
description: In the service robots field, a mobile robot must be able to navigate and repeat previously defined paths. This paper aims to develop a technique capable of teaching and repeating (T&R) a path taken by a mobile robot. We evaluated using a differential robot. The developed system is integrated with the ROS framework and uses the mobile base, which is built with self-balancing scooter components. When changes need to be made in the environment, a user must generate a new path by teleoperating the robot, and the system can repeat new paths autonomously. The proposed approach consists of using Bezier curves to represent the paths taken by the user. The proposed method implements a T &R technique to navigate a mobile robot. Results show the worst maximum average of percentage error (MPE) using this method was only 1.361 % in adapting the Bezier curve to the points where the robot was taught, satisfactorily representing the path. In the repeating process, the worst MPE was 9.983%.

Autoencoder-based Super-Resolution Approach for Aerial Robot Navigation
type: item
description: Images are increasingly used in the navigation of autonomous aerial vehicles. However, processing images locally in aerial robots can be very computationally and energy-intensive. In this sense, it is increasingly common to use remote data processing for applications involving mobile robots. This paper addresses the problem of super-resolution as a strategy for remote processing of aerial images, considering the proposed algorithm as a technique that reconstructs high-resolution images from low-resolution images captured by the aerial vehicle. To this end, we propose an approach called AESR, based on Autoencoder architecture for generating high-definition images, integrating skip-connections and self-attention modules to improve the learning process. The results indicate the high performance of our approach, validating the learning process based on autoencoder. Moreover, the approach achieved high accuracy even in challenging images representing different environments. The experiments demonstrate the robustness and accuracy of our approach, overcoming state-of-the-art techniques, through the use of the quality metrics PSNR, SSIM, LPIPS, DISTS, NIQE, and BRISQUE.

Comparison of Wheel Odometry and Visual Odometry for Low-Cost Vehicle Navigation
type: item
description: This paper presents a comparative study of Wheel Odometry (WO), which relies on measurements from wheel en-coders, and Visual Odometry (VO), which uses images captured by a monocular camera to estimate the vehicle movement, for the purpose of low-cost vehicle navigation. The analysis reveal the strengths and limitations of each method, offering insights into their suitability for different applications. The ultimate goal of the paper is to guide the selection of odometry techniques in designing low-cost, efficient vehicle navigation systems. Results from simulated experiments suggest that, while VO can offer higher accuracy in complex environments, WO remains a viable and cost-effective option for simpler navigation tasks, especially when the associated wheel radius errors are correlated, i.e., similar for both wheels, and do not exceed ±0.26%.

Minimum Time Footstep Planning for Simulated Robot Soccer Kicks Using Model Predictive Control
type: item
description: This work contributes with a footstep planner that applies Model Predictive Control techniques, along with non-linear and mixed-integer numerical optimization, to generate footstep plans for the NAO humanoid robot to kick a soccer ball, within the context of the Robocup Soccer Simulation 3D league. The resulting planner can easily be adapted to other Robocup leagues and applications that require footstep planning. The planner accounts for several constraints related to the employed physical platform, as well as obstacles that may be present in the environment, and minimizes the amount of footsteps present. Two different approaches to find the plans with the least amount of footsteps were proposed, namely the Increasing Horizon Method (IHM) and Constraint Relaxation Method (CRM), and the resulting plans and execution times for different parameters were studied. The footstep plans generated using both methods display interesting emergent behaviors, such as rotating a foot to extend the next footstep's reach, or placing footsteps in a way that, at the end of the plan, the robot faces a completely different direction than at the start.

Deep Deterministic Policy Gradient and Computer Vision for Autonomous Wheelchair Navigation in Human-Shared Environments
type: item
description: We present an innovative approach to autonomous navigation for motorized wheelchairs in shared indoor spaces with human presence, combining Deep Reinforcement Learning and Computer Vision. The primary aim of this study is to enhance the well-being of individuals with disabilities who rely on such assistance for their mobility needs. Our results demonstrate that the Deep Deterministic Policy Gradient (DDPG) algorithm combined with computer vision techniques outperforms the Deep Q-Network (DQN) in both efficiency and stability. Throughout all analyzed stages, DDPG achieved higher average success rates: 98% (Stage 01), 89% (Stage 02), 86% (Stage 03), and 86% (Stage 04), showcasing generalization capabilities and consistently superior performance in diverse settings. In contrast, DQN struggled to avoid collisions, resulting in significantly lower average success rates: 3% (Stage 02), 14% (Stage 03), and 29% (Stage 04). These findings highlight the promising potential of our proposed solution and contribute to the advancement of research in this field.

Improved Defensive Strategy in RoboCup Small Size League using Deep Reinforcement Learning
type: item
description: The Small Size League (SSL) is one of the old-est leagues in RoboCup, an international scientific initiative whose objective is to advance the state-of-the-art in robotics. The matches are highly dynamic and competitive, an excellent environment to exercise and extend the latest decision-making techniques. In this work, we focus on the planning problem of the defense strategy in the SSL context. Our contribution lies in proposing a method for learning such behaviors using Deep Reinforcement Learning (DRL) algorithms. Through this technique, we intend to apply a more automated process than manually adjusting the heuristics used to handcraft such skills in code. For this purpose, the RoboCup Small Size League standard simulator grSim was adapted in order to implement a synchronous mode. Furthermore, we integrated this new simulator with ITAndroids team's code base and with the DRL algorithms provided by the Stable Baselines 3 library. With this setup, we successfully trained an agent using Proximal Policy Optimization (PPO) and Soft Actor-Critic (SAC), the state-of-the-art for continuous control reinforcement learning algorithms. Moreover, we demonstrate that the resulting policies outperform the hand-coded counterparts, showing potential to improve the team's overall defense strategy.

Reinforcement Learning Applied to Very Small Size Soccer Decision-Making, Trajectory Planning and Control In Penalty Kicks
type: item
description: In this work, we propose a Reinforcement Learning (RL) training methodology using Proximal Policy Optimization (PPO) and Curriculum Learning (CL) to make simulated Very Small Size Soccer robots learn to convert penalty kicks against two types of opponents: the “line follow” goalkeeper, which defends the goal by following the goal line, and the offensive goalkeeper, which uses the univector field navigation technique to attack the ball. The RL agents trained using this methodology demonstrated sophisticated penalty kick skills with high conversion rates. The best-evaluated RL agent achieved a conversion rate of over 90% against the “line follow” goalkeeper and of over 71% against the offensive goalkeeper. Comparisons with the univector agent showed that the RL agents significantly outperformed it, with conversion rates 78.71% higher against the “line follow” goalkeeper and 1997.66% higher against the offensive goalkeeper.

A Platform for Manufacturing and Operation of Robot Systems
type: item
description: The industry, since its beginnings, has developed itself through technological leaps aiming to improve its efficiency and productivity. Industry 4.0 is the most recent paradigm that promises to revolutionize production through the integration of information technology in all of its processes. It integrates manufacturing, operations, and maintenance in a single ecosystem comprised of a diverse range of IoT devices, artificial intelligence, and a huge amount of data. This paper elaborates on the implementation of Industry 4.0 concepts into the manufacturing and operation processes of a robotics competition team. The concepts were implemented through a web platform that integrates all of the group's manufacturing and operation processes in a single database. This aggregation is achieved by identifying each of the team's items using Unique Universal Identifiers (UUID). This identification makes it possible to register exactly which item is being used in each robot, when the robot was manufactured, the last time it had to go through maintenance, who has participated in each of those processes, etc. In addition, the web platform, being populated with the Bill of Materials and documentation of each project, is able to help the manufacturing process by supplying the student with a structured step-by-step guide and documentation on how to build each of the projects designed by the team. The Industry 4.0 platform, in that way, can both integrate and register everything that happens in the workshop and improve the processes by guiding the student through each step of the manufacturing process. Finally, for documentation and experimental evaluation, the processes that use the platform were modeled using Business Process Model and Notation (BPMN).

Automating the Evaluation of the Scalability, Flexibility, and Robustness of Collective Behaviors for Robot Swarms
type: item
description: Robot swarms are large self-organizing groups of robots that coordinate to collectively perform missions that escape their individual capabilities. In a robot swarm, the individuals operate using local perception and communication, without relying on a leader or external infrastructure for coordination. These characteristics help robot swarms achieve desirable properties, such as scalability, flexibility, and robustness. In this paper, we use recently proposed experimental protocols to evaluate these properties in various typical collective behaviors for robot swarms. We focus on demonstrating that the joint application of defined protocols can help streamline and automate evaluation and reporting processes in swarm robotics research. In our experiments, instances of robot control software for typical collective behaviors are systematically simulated and evaluated across different environmental configurations and swarm sizes. We show how automated tools can facilitate the evaluation of swarm robotics properties.

Computer Vision for Space Robotics: CubeSat Detection and Tracking with OpenCV
type: item
description: Development of robotic manipulators for space operations is crucial to meet demands for small tasks, reducing astronaut risk via autonomous systems. Computer vision techniques provide the space robot with information about the target object for maintenance or repositioning, such as a CubeSat. To fulfill these requirements, this paper presents the development of a monocular vision system with the aim to provide visual detection, tracking and distance estimation of small satellites like CubeSats. The system, built using OpenCV, is designed to identify, track, and estimate the distance of a 1 U CubeSat within a controlled test environment simulating spatial conditions. By leveraging a combination of background subtraction, edge detection, and geometric analysis, available in OpenCV, the system effectively isolates the CubeSat from dynamic backgrounds, maintains robust tracking, and provides accurate distance estimations. Extensive testing across various scenarios demonstrated that the system performs particularly well in object tracking. Despite the challenges posed by varying lighting conditions and the nanosatellite's small size at greater distances, the system proved to be reliable, albeit limited. These findings underscore the potential of the system for applications in autonomous navigation and satellite servicing.

An Expanded Latent Space Autoencoder for Land Cover Classification of Remote Sensing Images from EuroSAT
type: item
description: Image classification has been instrumental in the interpretation and labeling of images in the field of remote sensing, computer vision, and in robotics applications. Machine learning and artificial intelligence algorithms, particularly artificial neural networks, are extensively utilized for this purpose. In this work we propose the Expanded Latent Space Autoencoder (ELSA) with a case use application to classify land cover data. The main idea on the ELSA network structure is to utilize the latent spaces of multiple internal autoencoders in order to create an expanded latent space. This expanded latent space extracts more information from the input data, and serves as input features for a more simpler classifier network. In order to evaluate the proposed network's ability to extract features and classify complex and multispectral images we employed it to the EuroSAT dataset. The results demonstrate a remarkable capacity for feature extraction using the ELSA network, with lower complexity, trained with a reduced number of images. The classifier network achieved a final accuracy of 98.7%, matching or exceeding the performance of more complex state-of-the-art models.

Enhancing Casting Manufacturing Quality Control with Vision Transformers
type: item
description: Ensuring quality control is a crucial task in modern manufacturing processes. Today, industries must guarantee the quality of their products to stay competitive. Automated visual inspection is one of the most effective ways to promote quality control, enabling the efficient inspection of 100% of the production volume. This paper deals with the quality control problem of casting discs for submersible pump impellers, ensuring quality at the casting stage. We propose an approach to detect defects in casting discs throughout the manufacturing process. Our methodology uses Vision Transformers (ViT), which employ self-attention mechanisms to capture spatial relationships between image patches, allowing the model to learn hierarchical visual representations. Both real and simulated experiments were conducted to validate the proposed approach. The results indicate an accuracy of 99.22% using the proposed ViT inspection. Moreover, the approach maintained high accuracy even in noisy images, with accuracies of 95.45% and 98.28% for Gaussian and Salt and Pepper noise, respectively, in the worst-case scenario. The experiments demonstrate the robustness and reliability of the approach, optimizing the manufacturing process.

Multi-Drone 3D Reconstruction of Architectural and Structural Entities
type: item
description: In this paper, we analyze the results of 3D reconstructions of buildings and monuments using a multi-drone sys-tem with predefined parameters. The drones follow an elliptical flight path with the same average speed in opposite directions and different altitudes for data acquisition of RGB videos. We set the drone cameras at a specific angle to avoid occlusion areas. Then, for 3D reconstructions, we used Convolutional Neural Networks techniques, specifically NeRF and Gaussian Splatting, in two different case studies: a simulation environment and a field test. As a result, we obtained detailed and visually accurate 3D models.

Musicalization of a Line-Following Robot for Educational Robotics Competitions
type: item
description: Educational Robotics competitions take place all over the world, with Robocup being the ultimate destination for most of these competitions. This is not different in Brazil. There are competitions for various educational levels, such as the Brazilian Robotics Competition (CBR) aimed at university students and the Brazilian Robotics Olympiad (OBR), intended for elementary and high school students. One of the categories in these competitions is the rescue category, where autonomous robots can be used to overcome challenges along a course, as well as rescue victims symbolized by objects. Various types of robots can be used in this category, utilizing wheels, chassis, claws, and sensors to assist in path detection, such as color, line, and proximity sensors. This category also has an extra challenge, where teams can present innovations in their own projects. In this sense, the project that performs best along the course and has the best innovation in the extra challenge earns points and can win the competition. One of the robots used in these competitions is from the project One Robot per Student (URA), of the Federal University of Rio Grande do Norte. The robot was designed both for use in competitions and for the training of teachers and teams. The use of music in Educational Robotics is a common approach and is known to be beneficial for education, but it is not as present in robotics competitions. Thus, as a matter of innovation, this work proposes to incorporate music into an autonomous robotics vehicle, in this case, the URA robot, making it a differentiating factor in educational robotics competitions. To achieve this, a buzzer actuator is attached to the URA vehicle's structure to produce sounds that signals the start and end of the vehicle's course in the rescue category challenge. These sounds are inserted into the programming through the frequencies of the melodies used in the URA vehicle's programming. The results of this work consider the effectiveness in c…

Effectiveness Analysis of Claw Designs on the URA Platform for the First Stage of the Brazilian Robotics Olympics
type: item
description: The usage of robotics as a supporting tool to educational activities in Brazil has gained traction with the popularization of both consumer-grade 3D printers and the promotion of events such as the Brazilian Robotics Olympiad (OBR). To compete in such contest, students need to design and make their own robots, which should be able to solving rescue tasks that most often require picking up a ball on some irregular arena ground. This paper analyzes different claw designs, both active (a design that uses a motor) and passive (a design that does not use a motor) in order to evaluate the abilities and capabilities of each design, on the One Robot per Student (URA) platform. We then propose a passive design with comparable effectiveness to the active design in order to reduce the complexity of robot construction. Experiments show that the approach reduces failure points and facilitates the process of teaching a lay-student on building a robot capable of surpassing the challenges proposed by the rescue line challenge from OBR at its fundamental level (one).

Robot Finder v2: Search and Ingestion of Educational Robotics Data from Youtube
type: item
description: Educational Robotics offers an interactive learning approach where students can turn abstract theories into concrete projects. With the exponential growth in content creation on internet platforms, finding specific, high-quality learning objects about robotics in education can be challenging. Platforms like YouTube, for example, have a vast collection of educational videos that cover various topics related to educational robotics. However, they are scattered among a massive amount of available data, making it difficult to have more assertive searches and identify the best resources. This work aims to present Robot Finder v2, a software that uses an automated approach to feed RepositORE, a repository of Learning Objects in Educational Robotics. The Robot Finder v2 searches and stores data from YouTube videos to make the search for this content simpler and more effective. The collected data feeds the RepostiORE, where these objects can be adapted and researched by users looking to acquire skills in educational robotics. For the objects to be found accurately, the software uses the YouTube Data API v3, which has a set of metadata in addition to the descriptions of the videos provided by their creators. The processing done in the Robot Finder optimizes the search and registration of information by mapping API endpoints and seeking correlations of metadata between RepositORE objects and YouTube videos.

Assessment Strategies in Robotics Courses: An Analysis of Methodology and Learning Outcomes
type: item
description: This study investigates the implementation of robotics classes in five schools, targeting both elementary and high school students. The classes, designed according to Fink's Significant Learning Taxonomy and integrating the National Common Curricular Base (BNCC) into subjects like mathematics and sciences, included practical activities, teamwork, and reflections on technology's societal impact. An assessment method based on Fink's Taxonomy was previously developed to validate these courses. Two evaluations were conducted at different phases to measure the development of competencies such as problem-solving, teamwork, and technical skills. This paper presents a structured literature review, detailed analysis of the methodology, application, and results, aiming to understand the actual impact of the robotics course and identify areas for future improvement. Analysis of theoretical questions revealed lower success rates in programming-related questions, suggesting the need for a rotation of functions among students. Despite some challenges, the self-assessment responses showed increased student interest and reduced difficulties over time.

Educational Robotics Public Policies Implementation Issues
type: item
description: We aim to analyze the implementation process of a public policy provided by a municipal law enacted for the provision of educational robotics as a complementary activity in the education network of Natal, RN, Brazil. From the perspective of educational robotics trainees (undergraduate students), we highlight the construction potential and the challenges faced out by them using an action research paradigm done in six school units of the municipal network. The performance of the monitors has been systematized in the period from late 2021 to 2024, from which we aim to understand the law implementation. Activity reports were produced with the actions developed in each school in the mentioned period, to carry out a reflective data analysis in accordance with the legal provisions in the municipal regulatory framework. Therefore, the main contribution of the article is the analysis carried out on the experiences of implementing RE as a public policy, which can be used or replicated in other basic level education networks in Brazil. This includes a possible methodology that can serve as a support for other similar projects abroad. Above all, we noticed that planning must be rigorous, and strictly followed, otherwise it will demotivate teachers and school students. Also, the interference of external actors such as monitors and teachers from Higher Education Institutions is another factor that we analyze as having a strong influence in the continuity of such initiative.

Educational Assistant Robot for Strengthening Children's Learning Using IoT
type: item
description: Digital Information and Communication Technolo-gies (DICTs) have increasingly become part of people's daily lives, whether they are children, adults, or the elderly. However, children's unfettered and increasingly early access to these technologies has been the subject of numerous studies aimed at measuring the impacts of their usage. In parallel, another issue arises: the influence of technology on education. When using technology, children often neglect their studies due to the distractions that technological devices (such as cell phones, computers, or tablets) can cause. In light of this, and aiming to reconcile technology with education, this work seeks to present the development of an intelligent educational assistant robot using the Internet of Things (IoT), with the goal of assisting children in the educational process through active learning approaches. Thus, upon completing the development of the robot, it was possible to verify its full functionality by engaging in interactions, asking questions, and providing details on distance and temperature values.
