About

Irene Sardellitti is a distinguished robotics researcher whose work sits at the intersection of safe human-robot interaction, variable stiffness actuation, and intelligent robot control. Her research has fundamentally advanced the design and control of compliant robotic systems intended to operate safely alongside humans in unstructured environments. Sardellitti's most influential contribution is her work on the CompAct-VSA, a novel variable stiffness actuator based on a lever arm mechanism with a continuously regulated pivot point, which has garnered nearly 200 citations and become a key reference in compliant actuation design. She pioneered the concept of hybrid actuation — combining pneumatic artificial muscles with small electrical actuators — laying important groundwork for human-friendly robot development. Her learning-based control strategy for safe human-robot interaction, cited over 145 times, demonstrated how task and robot redundancy can be intelligently exploited to protect human operators during collaborative tasks. With contributions spanning impedance estimation, stiffness control, and online parameter identification for variable stiffness joints, Sardellitti has helped shape the theoretical and practical foundations of modern compliant robotics. Her cumulative citation record reflects sustained influence across the field, making her work essential reading for researchers and students pursuing advances in safe, adaptive, and human-centered robotic systems.
