SoRoMoX: Fast, Differentiable, and Parallelizable Soft Robot Models
Maximilian Stölzle, Solange Gribonval, Daniel Feliu-Talegon +9
Reduced-order models based on Cosserat-rod theory are now well established, and modeling theory is no longer the primary bottleneck in soft-robot control. Their implementations, ho…
Soft Swing-up: Benchmarking Model-Based Optimal Control for Rigid-Soft Underactuated Systems
Daniele Caradonna, Nikhil Nair, Anup Teejo Mathew +5
Continuum soft robots are inherently underactuated and subject to intrinsic input constraints, making dynamic control particularly challenging, especially in hybrid rigid-soft robo…
A virtual-variable-length method for robust inverse kinematics of multi-segment continuum robots
Weiting Feng, Federico Renda, Yunjie Yang +1
This paper proposes a new, robust method to solve the inverse kinematics (IK) of multi-segment continuum manipulators. Conventional Jacobian-based solvers, especially when initiali…
Coordinated Manipulation of Hybrid Deformable-Rigid Objects in Constrained Environments
Anees Peringal, Anup Teejo Mathew, Panagiotis liatsis +1
Coordinated robotic manipulation of deformable linear objects (DLOs), such as ropes and cables, has been widely studied; however, handling hybrid assemblies composed of both deform…
Collision Detection with Analytical Derivatives of Contact Kinematics
Anup Teejo Mathew, Anees Peringal, Daniele Caradonna +2
Differentiable contact kinematics are essential for gradient-based methods in robotics, yet the mapping from robot state to contact distance, location, and normal becomes non-smoot…
Learning User Interaction Forces using Vision for a Soft Finger Exosuit
Mohamed Irfan Refai, Abdulaziz Y. Alkayas, Anup Teejo Mathew +2
Wearable assistive devices are increasingly becoming softer. Modelling their interface with human tissue is necessary to capture transmission of dynamic assistance. However, their…
