Tangled: Learning to untangle ropes with RGB-D perception

Wen Hao Lui, Saxena, Ashutosh·2013·2013 IEEE/RSJ International Conference on Intelligent Robots and Systems

Abstract

In this paper, we address the problem of manipulating deformable objects such as ropes. Starting with an RGB-D view of a tangled rope, our goal is to infer its knot structure and then choose appropriate manipulation actions that result in the rope getting untangled. We design appropriate features and present an inference algorithm based on particle filters to infer the rope's structure. Our learning algorithm is based on max-margin learning. We then choose an appropriate manipulation action based on the current knot structure and other properties such as slack in the rope. We then repeatedly perform perception and manipulation until the rope is untangled. We evaluate our algorithm extensively on a dataset having five different types of ropes and 10 different types of knots. We then perform robotic experiments, in which our bimanual manipulator (PR2) untangles ropes successfully 76.9% of the time.

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.
