Error-State Model Predictive Path Integral Control of Tendon-Driven Continuum Robots Using Cosserat Rod Dynamics With Strain Parametrization

RA-L 2026

This paper presents an error-state Model Predictive Path Integral (MPPI) framework for tendon-driven continuum robots (TDCRs). Tracking-error dynamics are formulated on a Lie group to preserve full pose geometry, yielding precise position-orientation error metrics. A nonlinear Cosserat-rod model wit

Few-Shot Physics-Informed Neural Network for Shape Reconstruction of Concentric-Tube Robots

ICRA 2026poster

Modeling concentric tube robots (CTRs) involves complex nonlinear continuum mechanics, and despite recent progress, physics-based models often lack an accurate representation of the experimental setups. To overcome these limitations, deep neural network-based models have been explored as alternative…

Learning Based Estimation of Tool-Tissue Interaction Forces for Stationary and Moving Environments

RA-L 2024

Accurately estimating tool-tissue interaction forces during robotics-assisted minimally invasive surgery is an important aspect of enabling haptics-based teleoperation. By collecting data regarding the state of a robot in a variety of configurations, neural networks can be trained to predict this in
