Abstract
In a diverse society, a crucial aspect of developing social robots is their ability to adapt to each individual's characteristics. There are two types of adaptation: physical and social. In pHRI, attention is paid to physical adaptation, but by investigating the social meaning of physical adaptation, we can extend it to social adaptation. Although it is a physical interaction, a handshake is a social action with complex meanings. We realized a handshaking robot with a Rowat-Selverston CPG controller that can synchronize with human movements. This study aims to clarify the relationship between physical and social adaptation by examining individual characteristics inferred from the internal state of the robot and human-robotic social attributes. Our finding is that there is a correlation between the internal state of the robot and some robotic social attributes. It was also found that the length of the handshake had little effect on these social perceptions. This study highlights the complex interplay between robot physical adaptability and social attribution, providing a foundation for developing robots capable of personalized and socially meaningful interactions.

Patrick Hénaff
Patrick Hénaff is Professor since September 2013. He obtained a MSc in robotics in 1989 and a PhD in robotics in 1994 from the Robotic laboratory of Paris, Université Pierre et Marie Curie (France). From 1997 to 2013, he was associate Professor at the Technical Institute of the University of Cergy-Pontoise. From 1997 to 2009, he worked as a researcher at the LISV (Systems Engineering Laboratory at the University of Versailles) and from 2009 to August 2013, he was a researcher at the ETIS laboratory at the University of Cergy-Pontoise, CNRS UMR 8051. From September 2013 to September 2023, he was Professor at the Ecole des Mines de Nancy , University of Lorraine, and in the LORIA laboratory, Neurorhythms team. He was head of the Complex Systems, Artificial Intelligence and Robotics department at LORIA from 2015 to 2022 and head of the Computer Science department at Mines Nancy from 2018 to 2023. Since October 2023, he is professor at the École Nationale d'Ingénieurs de Brest (France) and researcher at the Lab-STICC Laboratory, Interaction department. His research focuses on bio-inspired control in robotics. They aim to gain a better understanding of the learning mechanisms involved in motor coordination in humans, in order to model them and integrate them into humanoid robot controllers so as to give the latter sensorimotor coordination learning capabilities. In particular, it is developing computational models of adaptive neural networks dedicated to controlling the rhythmic movements of humanoid robots.
