Abstract
We propose a method that simultaneously
estimates and controls extrinsic contact with tactile feedback.
The method enables challenging manipulation tasks that
require controlling light forces and accurate motions in
contact, such as balancing an unknown object on a thin rod
standing upright. A factor graph-based framework fuses a
sequence of tactile and kinematic measurements to estimate and
control the interaction between gripper-object-environment,
including the location and wrench at the extrinsic contact
between the grasped object and the environment and the grasp
wrench transferred from the gripper to the object. The same
framework simultaneously plans the gripper motions that make
it possible to estimate the state while satisfying regularizing
control objectives to prevent slip, such as minimizing the grasp
wrench and minimizing frictional force at the extrinsic contact.
We show results with sub-millimeter contact localization error
and good slip prevention even on slippery environments, for
multiple contact formations (point, line, patch contact) and
transitions between them. See supplementary video and results
