A Transition-Aware Method for the Simulation of Compliant Contact With Regularized Friction

RA-L 2020

Multibody simulation with frictional contact has been a challenging subject of research for the past thirty years. Rigidbody assumptions are commonly used to approximate the physics of contact, and together with Coulomb friction, lead to challengingto-solve nonlinear complementarity problems (NCP).

A pressure field model for fast, robust approximation of net contact force and moment between nominally rigid objects

IROS 2019poster

We introduce Pressure Field Contact (PFC), an approximate model for predicting the contact surface, pressure distribution, and net contact wrench between nominally rigid objects. PFC combines and generalizes two ideas: a bed of springs (an `elastic foundation') and hydrostatic pressure. Continuous p…
