Origin of continental margin morphology: Submarine-slide or downslope current-controlled bedforms, a rock magnetic approach
Morphological features observed in both swath bathymetry and seismic reflection data are not unique, which introduces uncertainty as to their origin. The origin of features observed in the Humboldt Slide has generated much controversy because the same features have been interpreted as a submarine failure deposit versus current-controlled sediment waves. It is important to resolve this controver...
متن کاملImpedance Control of a Teleoperated Mini Excavator
A position-based impedance controller for excavator-type manipulators has been developed in our laboratory. This paper describes the proposed impedance controller and presents supporting experimental results. First, the problem of impedance control for a single hydraulic actuator is addressed and a method is presented for stability analysis. Steady-state position and force tracking of the close...
متن کاملA robotic excavator for autonomous truck loading
Excavators are used for the rapid removal of soil and other materials in mines, quarries, and construction sites. The automation of these machines offers promise for increasing productivity and improving safety. To date, most research in this area has focussed on selected parts of the problem. In this paper, we present a system that completely automates the truck loading task. The excavator use...
متن کاملImpedance control of a teleoperated excavator
Earth-moving machines such as hydraulic excavators are usually used for carrying out contact tasks. Impedance control can be employed as an approach for achieving compliant motion in such tasks. This paper describes a position-based impedance controller that has been developed in our laboratory for excavator-type manipulators, and presents supporting experimental results. First, the problem of ...
متن کاملNonlinear Oscillations of a Submarine
This is a part of the general program of investigation of nonlinear diierential equations by wavelet{homoclinic methods. We consider the problem of description of oscillation of a beam (circular cylindrical shell) contacting with a semi-innnite channel lled with compressible liquid (a model for submarine oscillations). We consider our problem for the case of two-frequency parametric perturbatio...
