The main goal of the research is to increase the measurement resolution of the ultrasonic range finders to meet the needs of vital signs non-contact registration based on the chest movements. The two-phase method is proposed to make distance estimates by sending the probe pulse trains, calculating the phase spectrum of the echo signal’s envelope and tracking its relevant components. During the first phase the rough TOF based estimate is made. During the second phase this estimate is corrected based on the phase spectrum of the echo signal’s envelope, the phase ambiguity is removed and the...

The paper is focused on the mobile robot convoying along the path travelled by some leader carrying the active ultrasonic beacon. The robot is equipped with the three- dimensional receiver array in order to receive both the ultrasonic wave and the RF wave marking the beginning the of the measurement cycle. To increase measurement reliability each receiver contains two independent measurement channels with the automatic gain control. The distance measurements are preprocessed to remove identify the artifacts and either remove them or substitute with the interpolated value. To estimate the...

An important addition to the inertial navigation system are magnetometers. Areas with magnetic field anomalies serve to determine the reference points. But the magnetometers are influenced from both the electrical equipment of the robot itself and robot’s parts configuration. Compensation of the robot’s self-influence on the readings of the magnetometers is carried out by computer tools. In order to obtain the initial data, live experiments are required in a natural enviroment. For simplifying data acquisition about the behavior of magnetometric systems of a mobile robot an facility is used,...

Robustness against parameter uncertainties is an important requirement for robot controllers to achieve high precision and fast tracking. This paper proposes a procedure to cover the uncertainties remaining after the exact linearization (also known as the computed torque method in robotics), and to design am additional linear compensator ?(?) to ensure robust performance and stability. The design of ?(?) involves standard ℋ_∞ . The procedure is presented in details for a model of a four degree-of-freedom SCARA manipulator. The load mass and friction coefficients are considered as uncertain...

An effective functioning of unmanned vehicles demands to process large amounts of various data coming from sensors, on-board data bases etc. Therefore date fusion technology is one of key-technologies for autonomous vehicles and systems. In order to systemize such data processing special so-called data fusion architectures are used (e.g. JDL, Waterfall, Boyd etc.). However some of those have a list of restrictions w. A goal of this paper is to present a novel data fusion architecture which could be used on board of unmanned vehicles. This architecture consists of 5 basic layers: parameters...

Project of robot in simulation system can be divided into two main parts. First is graphical model, and second is physical model. This paper discusses results of using tools for 3D modelling and building physical models. Graphical models are developed using 3dsMax software from CAD model. It is possible to perform straight conversion from the CAD model to a graphical game-ready model but results are poor. The most serious issues were performance, and texturing. Graphical models had to be created from scratch. Mechanical part was developed with Vortex Editor. Vortex Editor is tool which...

This paper describes results of effectiveness test of simulator for e-training operators of tele-operated vehicles. The test has been conducted with 20 participants (Warsaw Military Univesity of Technology students) divided into two groups. First group, numbering 11 persons, operated Dromader robot without previous training on the simulator. Members of the second 9-persons group went through simulator training before operating the robot. The trial was composed of two exercises. First of them was devoted to test driving abilities of the operators. The task for operator i was to cover the...

Within the frame of a European project called Eura-Thermal, the general objective was to upgrade the regional metrological infrastructure (Bosnia & Herzegovina, Croatia, Ireland, Serbia...) with new capabilities, especially in the field of thermal measurements. This paper highlights the strategy used for improving in the short term, scientific knowledge transfer and the capabilities of different emerging institutes. Furthermore, as a main output, the impacts and benefit for Industry and for the end-users are also presented as examples.

The main objective of present study is the definition of bio-functional foods and the investigation of attitude of consumers toward the market and consumption of comestible snails in the wider region of Thessalonica. The questionnaire of particular study was applied in sample of 353 individuals at the duration: 13 December his 2013 until 28 his April 2014 in the urban group of Thessalonica. The questions that included it was for the most part “closed” type, so that it can become statistical treatment and analysis of elements in order to results a line of conclusions. The analysis of elements...

Field commodities are exposed to fungal contamination with potential negative impact on human health. Bioactive plant molecules, as for example antioxidant compounds present in common buckwheat (Fagopyrum esculentum Moench), can provide natural means of biocontrol. To this purpose, the ability of flavonols extracted from common buckwheat hull to modulate, in in vitro conditions, Aspergillus flavus production of aflatoxin B 1 (AFB 1 ) was tested in comparison to synthetic rutin. Positive results achieved let infer that the extract could be furtherly tested also in vivo.
