Title: Real-Time Dynamic-aware Trajectory Planning for Mobile Robots in Indoor Environments Abstract: Service robots are increasingly used in dynamic indoor spaces such as offices, hospitals, or universities, where people and moving objects constantly modify the environment. For safe and efficient operation, a robot must detect and react to these changes in real time. The TIAGo-2 robot (PAL Robotics) provides an ideal research platform for this task. It integrates LiDAR, RGB-D sensors, and a differential base, with full support for ROS 2, including mapping and navigation modules. However, these standard navigation pipelines-based on slam_toolbox and Navigation2-are primarily designed for static environments. When people or objects move within the robot's workspace, its local planner often fails to anticipate or smoothly avoid dynamic obstacles. This internship aims to extend the TIAGo-2 navigation stack by adding a LiDAR-based dynamic obstacle detection module and a reactive...

Internship Topic Stress and emotion monitoring systems play a crucial role in mental health management, especially given the global rise in psychological disorders. Wearable devices equipped with sensors such as ECG (electrocardiogram), PPG (photoplethysmogram), EDA (electrodermal activity), and motion sensors provide a rich source of data for stress and emotion analysis. However, the high dimensionality and noise present in these multimodal datasets pose challenges for efficient processing and interpretability. Feature selection is essential for building robust and interpretable models. Recent advancements in explainable AI (XAI) emphasize the need to ensure that selected features provide understandable information about emotional and stress states, which strengthens trust and adoption by...
