Linear quadratic control of nonlinear systems with Koopman operator learning and the Nyström method

1 code implementation5 Mar 2024 Edoardo Caldarelli, Antoine Chatalic, Adrià Colomé, Cesare Molinari, Carlos Ocampo-Martinez, Carme Torras, Lorenzo Rosasco

In this paper, we study how the Koopman operator framework can be combined with kernel methods to effectively control nonlinear dynamical systems.

Towards Transferring Tactile-based Continuous Force Control Policies from Simulation to Robot

no code implementations13 Nov 2023 Luca Lach, Robert Haschke, Davide Tateo, Jan Peters, Helge Ritter, Júlia Borràs, Carme Torras

The advent of tactile sensors in robotics has sparked many ideas on how robots can leverage direct contact measurements of their environment interactions to improve manipulation tasks.

Benchmarking the Sim-to-Real Gap in Cloth Manipulation

no code implementations14 Oct 2023 David Blanco-Mulero, Oriol Barbany, Gokhan Alcan, Adrià Colomé, Carme Torras, Ville Kyrki

The dataset is collected by performing a dynamic as well as a quasi-static cloth manipulation task involving contact with a rigid table.

Deformable Surface Reconstruction via Riemannian Metric Preservation

no code implementations22 Dec 2022 Oriol Barbany, Adrià Colomé, Carme Torras

Estimating the pose of an object from a monocular image is an inverse problem fundamental in computer vision.

The dGLI Cloth Coordinates: A Topological Representation for Semantic Classification of Cloth States

no code implementations14 Sep 2022 Franco Coltraro, Josep Fontana, Jaume Amorós, Maria Alberich-Carramiñana, Júlia Borràs, Carme Torras

Robotic manipulation of cloth is a highly complex task because of its infinite-dimensional shape-state space that makes cloth state estimation very difficult.

Controlled Gaussian Process Dynamical Models with Application to Robotic Cloth Manipulation

1 code implementation11 Mar 2021 Fabio Amadio, Juan Antonio Delgado-Guerrero, Adrià Colomé, Carme Torras

A CGPDM is constituted by a low-dimensional latent space, with an associated dynamics where external control variables can act and a mapping to the observation space.

Online Action Recognition

no code implementations14 Dec 2020 Alejandro Suárez-Hernández, Javier Segovia-Aguas, Carme Torras, Guillem Alenyà

It consists in recognizing, in an open world, the planning action that best explains a partially observable state transition from a knowledge library of first-order STRIPS actions, which is initially empty.

Encoding cloth manipulations using a graph of states and transitions

no code implementations30 Sep 2020 Júlia Borràs, Guillem Alenyà, Carme Torras

Cloth manipulation is very relevant for domestic robotic tasks, but it presents many challenges due to the complexity of representing, recognizing and predicting the behaviour of cloth under manipulation.

Gaussian-Process-based Robot Learning from Demonstration

no code implementations23 Feb 2020 Miguel Arduengo, Adrià Colomé, Joan Lobo-Prat, Luis Sentis, Carme Torras

Endowed with higher levels of autonomy, robots are required to perform increasingly complex manipulation tasks.

STRIPS Action Discovery

no code implementations30 Jan 2020 Alejandro Suárez-Hernández, Javier Segovia-Aguas, Carme Torras, Guillem Alenyà

This knowledge is usually handcrafted and is hard to keep updated, even for system experts.

Dynamic Cloth Manipulation with Deep Reinforcement Learning

no code implementations31 Oct 2019 Rishabh Jangir, Guillem Alenya, Carme Torras

Finally, we compare different combinations of control policy encodings, demonstrations, and sparse reward learning techniques, and show that our proposed approach can learn dynamic cloth manipulation in an efficient way, i. e., using a reduced observation space, a few demonstrations, and a sparse reward.

Robust and Adaptive Door Operation with a Mobile Robot

1 code implementation25 Feb 2019 Miguel Arduengo, Carme Torras, Luis Sentis

In addition, we propose a versatile Bayesian framework that endows the robot with the ability to infer the door kinematic model from observations of its motion and learn from previous experiences or human demonstrations.

Exploiting Single-Cycle Symmetries in Continuous Constraint Problems

no code implementations15 Jan 2014 Vicente Ruiz de Angulo, Carme Torras

Symmetries in discrete constraint satisfaction problems have been explored and exploited in the last years, but symmetries in continuous constraint problems have not received the same attention.
