Force feedback sensors are useful for the planning of robotic digging trajectories. In particular, when combined with force-control algorithms it becomes possible to sense buried objects and to determine the weight of excavated materials. The proposed force sensor system makes use of hydraulic cylinder pressure and thereby measures machine force indirectly.(More)
In this paper we present the parallel solver χnavis, a general purpose solver for Computational Fluid Dynamics (CFD). The solver is based on the finite volume discretization of the unsteady incompressible Navier-Stokes equations; main features include a level set approach to handle free surface flows and a dynamical overlapping grids approach, which(More)
