A Variable Stiffness Anthropomorphic Finger Through Embodied Intelligence Design

RA-L 2024

Most existing anthropomorphic robotic fingers are either too stiff to offer compliance, or too soft to provide postural stability. Yet human subjects tend to stiffen their finger when producing fingertip forces and lower their joint stiffness when grasping objects. Variable joint stiffness is theref

A Healable Resistive Heater as a Stimuli-Providing System in Self-Healing Soft Robots

RA-L 2022

Self-healing polymers can address the damage susceptibility in soft robotics. However, in most cases, their healing requires a heat stimulus, provided by an external device. This letter presents a self-healing soft actuator with an integrated healable flexible heater, functioning as the stimuli-prov

Quasi-Static FEA Model for a Multi-Material Soft Pneumatic Actuator in SOFA

RA-L 2022

The increasing interest in soft robotics has led to new designs that exploit the combination of multiple materials, increasing robustness and enhancing performance. However, the combination of multiple non-linear materials makes modelling and eventual control of these highly flexible systems challen

Topology optimized multi-material self-healing actuator with reduced out of plane deformation

IROS 2022poster

Recent advances in soft robotics in academia have led to the adoption of soft grippers in industrial settings. Due to their soft bending actuators, these grippers can handle delicate objects with great care. However, due to their flexibility, the actuators are prone to out-of-plane deformations upon…

From a Disposable Ureteroscope to an Active Lightweight Fetoscope - Characterization and Usability Evaluation

RA-L 2018

The twin-to-twin transfusion syndrome is a severe fetal anomaly appearing in up to 15% of identical twin pregnancies. This anomaly occurs when twins share blood vessels from a common placenta. The complication leads to an unbalanced blood transfusion between both fetuses. A current surgical treatmen
