Query: OmniHang: Learning to Hang Arbitrary Objects using Contact Point
  Correspondences and Neural Collision Estimation   In this paper, we explore whether a robot can learn to hang arbitrary objects
onto a diverse set of supporting items such as racks or hooks. Endowing robots
with such an ability has applications in many domains such as domestic
services, logistics, or manufacturing. Yet, it is a challenging manipulation
task due to the large diversity of geometry and topology of everyday objects.
In this paper, we propose a system that takes partial point clouds of an object
and a supporting item as input and learns to decide where and how to hang the
object stably. Our system learns to estimate the contact point correspondences
between the object and supporting item to get an estimated stable pose. We then
run a deep reinforcement learning algorithm to refine the predicted stable
pose. Then, the robot needs to find a collision-free path to move the object
from its initial pose to stable hanging pose. To this end, we train a neural
network based collision estimator that takes as input partial point clouds of
the object and supporting item. We generate a new and challenging, large-scale,
synthetic dataset annotated with stable poses of objects hung on various
supporting items and their contact point correspondences. In this dataset, we
show that our system is able to achieve a 68.3% success rate of predicting
stable object poses and has a 52.1% F1 score in terms of finding feasible
paths. Supplemental material and videos are available on our project webpage.
