About

Xavier Greppin is a pioneering roboticist whose work has fundamentally shaped the field of human-robot interaction in public spaces. His most significant contribution came from orchestrating the deployment of personal robots at Expo.02, a large-scale public exposition where his team operated multiple autonomous mobile robots simultaneously. This groundbreaking work, detailed in his highly cited 2003 paper "Robox at Expo.02" (228 citations), demonstrated how robots could engage with thousands of non-expert visitors in complex, collaborative interactions. Greppin's research addresses the critical challenges of multi-robot control, visitor flow management, and interaction management in real-world settings. His 2003 paper on the interactive autonomous mobile system RoboX (65 citations) established foundational principles for secure, reliable human-robot communication using multiple modalities simultaneously. Through his development of the SOUL environment for tour-guiding robots, Greppin pioneered techniques that enable robots to maintain social awareness while managing crowd dynamics. His work remains essential reading for researchers interested in deploying robots in public spaces, balancing technical reliability with natural human interaction.
