She highlights the importance of designing robots that interact with humans in responsible and beneficial ways, considering the potential long-term impacts on human values and social norms.

9.- Collaborative Human-Robot Interaction: Dragan explores the concept of collaborative interaction between humans and robots, where both parties contribute to achieving common goals. This collaboration requires robots to not only understand human intentions and preferences but also to actively adapt their behavior to facilitate cooperation and mutual understanding.

10.- The Evolution of Robotics and AI: Reflecting on the advancements in robotics and AI, Dragan discusses the rapid progress in the field and the increasing capabilities of robotic systems. She stresses the need for continued innovation and research to address the remaining challenges in human-robot interaction, ensuring that robots can effectively serve and augment human abilities in a wide range of applications.

11.- Interactive Dynamics with Autonomous Vehicles: Dragan delves into the nuanced dynamics of interaction between autonomous vehicles and human drivers. She explains how autonomous vehicles must not only predict human actions but also understand how their own actions can influence human behavior, enhancing coexistence on the road.

12.- Underactuated Systems and Human Influence: The concept of underactuated systems is explored, where the behavior of humans (considered as part of the system) can be influenced but not directly controlled by the autonomous system. This approach highlights the indirect control mechanisms that autonomous vehicles can leverage to navigate complex social situations.

13.- Pedestrian Behavior Analysis: Dragan shares her observations on pedestrian behavior, noting the subtle negotiations and unspoken rules that govern interactions between pedestrians and vehicles. This highlights the importance of understanding nuanced human behaviors for designing effective autonomous systems.

14.- Civil Inattention in Human Behavior: The phenomenon of civil inattention, where individuals navigate shared spaces with minimal direct interaction, is discussed. Dragan notes its relevance in designing autonomous systems that can predict and adapt to human presence without requiring explicit communication.
