A Virtual Excavator for Controller Development and Evaluation
In order to facilitate the testing and evaluation of control strategies and operator environments designed for heavy duty hydraulic machines, an excavator simulator has been developed and is described in this paper. The simulator comprises an impedance model of the excavator arm, a model for the bucket-ground interaction forces, a graphical environment and a haptic interface. This paper describ...
متن کاملThe Virtual Environment for Force-feedback Experiment of Excavator Using a Noveldesigned Haptic Device
ABSTRACT: This paper describes an approach force-feedback of excavator which is considered for tele-operation using a novel designed haptic device in virtual environment. This study has two main themes, the newly designed haptic device and force-feedback algorithm in virtual environment for excavator. The device can be controlled by human arm joint. Using the device, motion of boom, arm and buc...
متن کاملEstimating trenching costs in FTTx network planning
In this paper we assess to which extent trenching costs of an FTTx network are unavoidable, even if technical side constraints are neglected. For that purpose we present an extended Steiner tree model. Using a variety of realistic problem instances we demonstrate that the total trenching cost can only be reduced by about 5 percent in realistic scenarios. This work has been funded by BMBF (Germa...
متن کاملGeneralization of Dodgson's "Virtual Center" Method; an Efficient Method for Determinant Calculation
Charles Dodgson (1866) introduced a method to calculate matrices determinant, in asimple way. The method was highly attractive, however, if the sub-matrix or the mainmatrix determination is divided by zero, it would not provide the correct answer. Thispaper explains the Dodgson method's structure and provides a solution for the problemof "dividing by zero" called "virtua...
متن کاملLASERS WITHOUT INVERSION: DENSITY OPERATOR METHOD
A quantum theory of a two and three-level laser with injected atomic coherence is developed by using a density operator method, to the best of our knowledge, for the first time. The initial atomic coherence plays an essential role. At steady state, the equation of motion for the density operator yields to exhibit laser without inversion and a phase locking but no threshold for the laser fie...
