Learning Models as Functionals of Signed-Distance Fields for Manipulation Planning

no code implementations2 Oct 2021 Danny Driess, Jung-Su Ha, Marc Toussaint, Russ Tedrake

We show that representing objects as signed-distance fields not only enables to learn and represent a variety of models with higher accuracy compared to point-cloud and occupancy measure representations, but also that SDF-based models are suitable for optimization-based planning.

Learning Neural Implicit Functions as Object Representations for Robotic Manipulation

no code implementations29 Sep 2021 Jung-Su Ha, Danny Driess, Marc Toussaint

Robotic manipulation planning is the problem of finding a sequence of robot configurations that involves interactions with objects in the scene, e. g., grasp, placement, tool-use, etc.

Approximate Inference-based Motion Planning by Learning and Exploiting Low-Dimensional Latent Variable Models

no code implementations22 Nov 2017 Jung-Su Ha, Hyeok-Joo Chae, Han-Lim Choi

Second, an approximate inference algorithm is used, exploiting through the duality between control and estimation, to explore the decision space and to compute a high-quality motion trajectory of the robot.
