Soft Robotics

Our work spans a full suite of soft robotic technologies such as soft manipulators, grippers, underwater and biomimetic robots for application to industry, healthcare, and extreme environments. In this regard, we conduct research on the development of novel soft actuation methods, sensing technologies, and control techniques.

Soft actuators and manipulators

We explore novel designs and fabrication techniques for creating soft robots using silicones, fabrics, 3d printed materials, and origami-inspired structures.

Soft sensing

We develop novel technologies for sensorizing soft actuators and robots. Over the years, we have developed optical fibre based sensors for shape sensing in soft manipulators, force and proximity sensors for soft interaction, and soft electronic skins for proprioception and exteroception in soft robots.
