abstract = {Object rearrangement is widely demanded in many of the
manipulation tasks performed by industrial and service
robots. Rearranging an object through planar pushing is
deemed energy efficient and safer compared with the
pick-and-place operation. However, due to the unknown
physical properties of the object, rearranging an object
toward the target position is difficult to accomplish. Even
though robots can benefit from multimodal sensory data for
estimating novel object dynamics, the exact estimation error
bound is still unknown. In this work, first, we demonstrate
a way to obtain an error bound on the center of mass (CoM)
estimation for the novel object only using a
position-controlled robot arm and a vision sensor.
Specifically, we extend Mason's Voting Theorem to object CoM
estimation in the absence of accurate information on
friction and object shape. The probable CoM locations are
monotonously narrowed down to a convex region, and the
extended voting theorems' guarantee that the convex region
contains the CoM ground truth in the presence of contact
normal estimation error and pushing execution error. For the
object translation task, existing methods generally assume
that the pusher-object system's physical properties and
full-state feedback are available, or utilize iterative
pushing executions, which limits the application of planar
pushing to real-world settings. In this work, assuming a
nominal friction coefficient between the pusher and object
through contact normal error bound analysis, we leverage the
estimated convex region and the Zero Moment Two Edge Pushing
method (Gao et al., 2023) to select the contact
configurations for object pure translation. It is ensured
that the selected contact configurations are capable of
tolerating the CoM estimation error. The experimental
results show that the object can be accurately translated to
the target position with only two controlled pushes at
most.},
