Optimizing a Continuum Manipulator’s Search Policy Through Model-Free Reinforcement Learning

IROS 2020poster

Continuum robots have long held a great potential for applications in inspection of remote, hard-to-reach environments. In future environments such as the Deep Space Gateway, remote deployment of robotic solutions will require a high level of autonomy due to communication delays and unavailability o…

Reduced Order vs. Discretized Lumped System Models with Absolute and Relative States for Continuum Manipulators

RSS 2019poster

A reliable, accurate, and yet simple dynamic model is important to analyze, design and control continuum manipulators. Such models should be fast, as simple as possible and user-friendly to be widely accepted by the ever-growing robotics research community. In this study, we introduce two new modeli…

Semi-Supervised Learning via Compact Latent Space Clustering

ICML 2018oral

We present a novel cost function for semi-supervised learning of neural networks that encourages compact clustering of the latent space to facilitate separation. The key idea is to dynamically create a graph over embeddings of labeled and unlabeled samples of a training batch to capture underlying s…
