Hierarchical Policy Blending as Inference for Reactive Robot Control

no code implementations14 Oct 2022 Kay Hansel, Julen Urain, Jan Peters, Georgia Chalvatzaki

To combine the benefits of reactive policies and planning, we propose a hierarchical motion generation method.

SE(3)-DiffusionFields: Learning smooth cost functions for joint grasp and motion optimization through diffusion

1 code implementation8 Sep 2022 Julen Urain, Niklas Funk, Jan Peters, Georgia Chalvatzaki

In this work, we focus on learning SE(3) diffusion models for 6DoF grasping, giving rise to a novel framework for joint grasp and motion optimization without needing to decouple grasp selection from trajectory generation.

Learning Implicit Priors for Motion Optimization

no code implementations11 Apr 2022 Julen Urain, An T. Le, Alexander Lambert, Georgia Chalvatzaki, Byron Boots, Jan Peters

In this paper, we focus on the problem of integrating Energy-based Models (EBM) as guiding priors for motion optimization.

Learning Stable Vector Fields on Lie Groups

no code implementations22 Oct 2021 Julen Urain, Davide Tateo, Jan Peters

Learning robot motions from demonstration requires models able to specify vector fields for the full robot pose when the task is defined in operational space.

ImitationFlow: Learning Deep Stable Stochastic Dynamic Systems by Normalizing Flows

no code implementations25 Oct 2020 Julen Urain, Michelle Ginesi, Davide Tateo, Jan Peters

We introduce ImitationFlow, a novel Deep generative model that allows learning complex globally stable, stochastic, nonlinear dynamics.
