About

Claudio Semini is the head of IIT's Dynamic Legged Systems (DLS) lab. He holds an MSc degree from ETH Zurich in electrical engineering and information technology. He spent 2 years in Tokyo for his research: MSc thesis at the Hirose Lab at Tokyo Tech and staff engineer at the Toshiba R&D center in Kawasaki working on mobile service robotics. During his PhD and subsequent PostDoc at IIT, he developed the quadruped robot HyQ and worked on its control. Since 2012 he leads the DLS lab. His research focus lies on the construction and control of highly dynamic and versatile legged robots in real-world environments. He has published over 100 articles in journals and peer-reviewed conferences. He is a co-founder and chair of the IEEE RAS Technical Committee on Robot Mechanisms and Design. He was the coordinator of the EU-funded ECHORD++ experiment HyQ-REAL (www.hyq-real.eu) and currently heads the IIT side of the Moog/IIT joint lab (moog.iit.it).
