Abstract

Grasp detection in clutter requires the robot to reason about the 3D scene from incomplete and noisy perception.In this work, we draw insight that 3D reconstruction and grasp learning are two intimately connected tasks, both of which require a fine-grained understanding of local geometry details.We thus propose to utilize the synergies between grasp affordance and 3D reconstruction through multi-task learning of a shared representation.Our model takes advantage of deep implicit functions, a continuous and memory-efficient representation, to enable differentiable training of both tasks.We train the model on self-supervised grasp trials data in simulation.Evaluation is conducted on a clutter removal task, where the robot clears cluttered objects by grasping them one at a time.The experimental results in simulation and on the real robot have demonstrated that the use of implicit neural representations and joint learning of grasp affordance and 3D reconstruction have led to state-ofthe-art grasping results.Our method outperforms baselines by over 10% in terms of grasp success rate.Additional results and videos can be found at https://sites.google.com/view/rpl-giga2021

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
