When Ant System algorithm is used to solve combinatorial optimization problems with precedence constraints, the computation of components list that can be used to extend the current partial solution is time consuming. For every component, the algorithm tests if the precedence constraints are met. In this work, a treatment list of components is proposed,(More)
In this paper is presented an algorithm to detect human faces using the orthogonal projection principle PCA (Principal Component Analysis) and a neural network classifier trained offline with a set of training images acquired from a webcam as well as from the CBLC and Manchester databases. The algorithm for the detection and tracking of faces will be(More)
This paper introduces the concept of “virtual pheromones” for use in controlling autonomous mobile robots. Virtual pheromones are stored in a map of the environment maintained by a “pheromone server”, which acts like a shared memory for all the agents. Autonomous agents communicate with the pheromone server by means of a radio(More)
This paper presents a real-time implementation of a fuzzy logic control algorithm applied to the mobile robot PatrolBot. PatrolBot is a wheeled mobile robot (WMR) with two driving wheels and two caster wheels. The design and implementation of the fuzzy controller is described and analyzed. Position is achieved from the robot and it is the entry of the(More)
This paper proposes a model for a reversible assembly line useful in order to analyze its structural properties. Wheeled mobile robots (WMRs) equipped with robotic manipulator are used in the disassembly operation. The developed model can be used in the stages of designing, configuring and sizing of an Assembly/Disassembly Mechatronic Line (A/DML). For the(More)
In this paper, two Petri Nets (PN) models of an assembly line and of an integrated mobile platform equipped with manipulator are proposed in order to perform disassembly. The first model is a discrete event model, where, both, the assembly/disassembly line and wheeled mobile robot (WMR) equipped with robotic manipulator (RM) are considered as discrete(More)
The new idea in this paper is to make a processing line capable of reprocessing pieces that have not passed the quality test. The focus is to provide a model of the processing line and to introduce in the process a wheeled mobile robot (WMR) equipped with a robotic manipulator (RM) in order to transport pieces, for reprocessing. For this purpose, an(More)
