About

Ricardo Sosa is a robotics researcher whose work spans reconfigurable mechanical systems, legged locomotion, modular robotics, and human-robot interaction. He is perhaps best known for his pioneering contributions to reconfigurable walking platforms, particularly his development of novel leg mechanisms based on Jansen-type linkages capable of producing multiple gait patterns. His 2015 paper on this topic has accumulated 70 citations and represents a significant advance in energy-efficient legged robot design, while related work on adaptive gait exploration (48 citations) and gait synchronization further consolidates his expertise in locomotion flexibility. Sosa has also made notable contributions to modular robotics through his work on nested reconfiguration — a concept he helped define and formalize — introducing the Hinged-Tetro module and theoretical frameworks that distinguish intra-, inter-, and nested reconfigurations in robot design. Beyond mechanical systems, his research extends into human-centered robotics, exploring robot-inclusive spatial design and robot ergonomics, advocating for cross-disciplinary collaboration between roboticists, architects, and designers. More recently, he has investigated creativity in social robots through human-robot interaction studies. With a body of work consistently bridging mechanical innovation and human-centered design, Sosa stands as a versatile and impactful figure in contemporary robotics research.
