Query: Learning Visual Shape Control of Novel 3D Deformable Objects from
  Partial-View Point Clouds   If robots could reliably manipulate the shape of 3D deformable objects, they
could find applications in fields ranging from home care to warehouse
fulfillment to surgical assistance. Analytic models of elastic, 3D deformable
objects require numerous parameters to describe the potentially infinite
degrees of freedom present in determining the object's shape. Previous attempts
at performing 3D shape control rely on hand-crafted features to represent the
object shape and require training of object-specific control models. We
overcome these issues through the use of our novel DeformerNet neural network
architecture, which operates on a partial-view point cloud of the object being
manipulated and a point cloud of the goal shape to learn a low-dimensional
representation of the object shape. This shape embedding enables the robot to
learn to define a visual servo controller that provides Cartesian pose changes
to the robot end-effector causing the object to deform towards its target
shape. Crucially, we demonstrate both in simulation and on a physical robot
that DeformerNet reliably generalizes to object shapes and material stiffness
not seen during training and outperforms comparison methods for both the
generic shape control and the surgical task of retraction.
