Center node: "6dls modeling non planar frictional surface contacts for grasping using 6d limit surfaces"
  Abstract: Robot grasping with deformable gripper jaws often results in non-planar surface contacts as the jaws deform to the object geometry and may lead to six-dimensional (6D) friction. We present a friction computation for curved surfaces by combining concepts of differential geometry and Coulomb friction. We propose two 6D limit surface (6DLS) models generalized from well-known three-dimensional LS (3DLS) models, which describe the friction-motion constraints for a single non-planar contact. We further introduce an algorithm to predict multi-contact grasp success by building a grasp wrench space with the 6DLS of each contact. Simulation results show that the 6DLS models reach up to 2.71% average fitting error with friction samples obtained from six parametric surfaces and 2473 meshed contacts from finite element method simulations of 24 objects and two types of gripper jaws. To evaluate the proposed 6DLS-based algorithm for grasp success prediction, we collect 280 physical grasps of ten 3D printed objects with a KUKA robot and a SCHUNK parallel-jaw gripper. Physical experiments suggest that the algorithm achieves 97.2% precision, a metric inversely related to false positive predictions, and 56.3% recall, a metric inversely related to false negative predictions. The 6DLS models increase recall by up to 15.3% over the 3DLS models without decreasing precision.
