Simple Models, Real Swimming: Digital Twins for Tendon-Driven Underwater Robots

ICRA 2026poster

Mimicking the graceful motion of swimming animals remains a core challenge in soft robotics due to the complexity of fluid-structure interaction and the difficulty of controlling soft, biomimetic bodies. Existing modeling approaches are often computationally expensive and impractical for complex con…

Camera-tracked Soft Underwater Robot Enabling Robust Orientation Control for Maneuverability

IROS 2025

Maneuverability in soft bio-inspired underwater robots, particularly for following complex trajectories, remains an unsolved challenge. In this work, we present a control approach based on a PD controller integrated with real-time camera feedback, enabling continuous and reliable free-swimming contr

Control and Morphology Optimization of Passive Asymmetric Structures for Robotic Swimming

RA-L 2023

Aquatic creatures exhibit remarkable adaptations of their body to efficiently interact with the surrounding fluid. The tight coupling between their morphology, motion, and the environment are highly complex but serves as a valuable example when creating biomimetic structures in soft robotic swimmers

An Experimental Validation of the Polynomial Curvature Model: Identification and Optimal Control of a Soft Underwater Tentacle

RA-L 2022

The control possibilities for soft robots have long been hindered by the lack of accurate yet computationally treatable dynamic models of soft structures. Polynomial curvature models propose a solution to this quest for continuum slender structures. Nevertheless, the results produced with this class
