Environment detection is important task for an autonomous robot. Obstacle avoidance is a must when the robot do indoor activity. I this case robot movement is done in corridors and rooms, which is similar to a maze. Distance from the walls can be sensed with different sensors, in the experiment infra-red sensors were used. There are several methods for obstacle detection and calculating the distance...
In the framework of designing a system for the estimation of the position of moving objects, this work treats the case of Dead Reckoning solution. The algorithm uses exteroceptive data coming from two degree of freedom Micro-electro mechanical system (MEMS) accelerometer to plot the trajectory of a mass point in a two-dimensional map. The mathematical model of the Dead Reckoning algorithm is based...
Man-machine interaction, human-robot interaction and robot behavior became an important factor of robotics, since the robotics as a separate research field appeared. Etho robotic is the science, which studies robot habit, which acts as animals or humans. Also it studies human reaction regarding the robot which acts as a dog, ant, or other animals. The paper intends to present a robot behavior model...
For the purpose of determining the pose (position and orientation) of a moving object, inertial sensors and magnetometer data are computed to enhance GNSS data accuracy. This paper develops a method called hybrid localisation that combines absolute localisation, using exteroceptive data, and dead reckoning technique, using proprioceptive data. The hybridisation technique uses tightly coupled approach...
The Mojette (MOT) transform is a relatively new method for image transformation. With the use of MOT on images, multimedia files, distributed databases before information transmission became possible to reconstruct the data even if some part of information were damaged. The Mojette transform similarly to the Radon transformation calculate a group of projection on an image block. As result of this...
This Real-time Industrial Ethernet IO system is a communication concept for implementing modular, distributed applications on the Ethernet. User data from the field devices are transmitted cyclically via a real-time industrial Ethernet channel to the process image of an automation control system. The paper, presents a very efficient method to measuring and analyzing the reaction times of IO device...
This paper analyses a fuzzy rule interpolation method implemented on different platforms. Fuzzy rule interpolation based control systems play a major role in robot control and have several kinds of implementations. The fuzzy control applications based on fuzzy rule interpolation with the contributions made by Johanyak Cs. [7], allowed the implementation of several fuzzy models. In fuzzy control applications...
The Mojette Transform is a mathematical transform that has approximately 20 years of research history. The transform is the exact definition of the Discrete Radon transform. Despite of the simplicity of its mathematics, this transform is a really computationally intensive procedure. The purpose of this paper is to introduce algorithms based on the Mojette Transform that the research group (composed...
The today computers, as taught in the elementary computer architecture courses, are based essentially on the principles, suggested by von Neumann in a 1946 report. Since that, only minor improvements have been carried out, although the impressive technical developments seem to hide this fact. In the meantime, also a whole software industry has grown up, and masses of society are using computers, sometimes...
Modern industrial quality monitoring systems are based on optical fibre sensors, microelectronic sensory technology and miniaturized infrared spectroscopy systems based on low-power, low-cost, high-efficient and innovative hardware solutions. The proposed paper presents development work related to create remote control system for monitoring water pollution petrochemical products using optical fibre...
Key elements and architecture of the developed optically powered atmosphere quality monitoring system are discussed. System design and some details of optically powered and optically controlled remote sensory module system design are presented. Finally some experimental results of system performance are presented.
The purpose of this article is to introduce the achievements reached with the Mojette Transform in recent years within our workgroup including from the simple description of the Mojette Transform and the Inverse Mojette Transform which originates form France to a theory of real time application. We introduced the benefits of the transform through its implementation in .Net environment. Describing...
The paper presents a short introduction to reconfigurable systems and why are they used or should be used in control of AC drives. The reconfigurable vector control system is introduced and there are treated the reconfiguration problems. There is analyzed the reconfigurable control system and it is motivated the need for reconfiguration in motor control. The control of the induction motor fed by the...
