“…Fig. 6 shows the values of Urbach energy as a function of the percentage of doping with zinc sulfide (ZnS), where we note that its value increases with the increase in the percentage of doping, which is consistent with the results reached by the researcher [37].…”

Pure and doped magnesium oxide (MgO) thin films were prepared with different volumetric ratios (0, 2, 4, 6, and 8%) of zinc sulfide (ZnS) on glass substrates at (350 °C) by chemical spray pyrolysis technique. The surface topography, absorption spectrum, absorption coefficient and Urbach energy of the prepared films were studied. The atomic force microscopy (AFM) results revealed that the surface topography of the prepared films changes as the percentage of doping with zinc sulfide (ZnS) increases. The absorbance spectrometry of the prepared films was measured by UV-vis. The Urbach energy of the prepared thin films increased by increasing the doping ratios with (ZnS).

In this paper, a new method for objects store in static environments, referred to as objects store system, is designed and constructed. This system consists of thirty boxes arranged in four columns to store and retrieve objects using the line follower robot. The storing and retrieving process is investigated by using a differential drive mobile robot which equipped by left and right infrared sensors to work as line follower robot. The trajectories of this robot is arranged according to the N-ary tree algorithm and enhanced by using the digital differential algorithm DDA to reduce the rabble occurrences. The address of each store box is considered as an access code with five binary digits which protect by using the radio frequency identification module (RFID). The objects store system is implemented on two experimental scenarios, one of them is used to test the time of arrival with respect to the number of store boxes and the other is used to test the average length of the paths. General TermsDifferential drive mobile robot, Object store system.

“…Also, the Path planning approaches are important aspects of multimobile robot formation. These approaches can be classified into global and local methods based on the sensor information available [10][11]. The global methods guarantees the reaching of the robots to their targets.…”

This paper denotes a survey on formation control of multimobile robot systems which drawn significant attention for the last years. It is concentrated on the stability of multi mobile robots when they obtained the required formation. Also this paper discusses the approaches of formation control and applications of them in changing and remote environments. Two classifications for the formation control methods are surveyed in this paper: the formation control strategies and the formation control stability. The differences among the surveyed approaches are discussed and the results are summarized.
