In a counterfeit clever control procedure, another productive methodology for an indoor robot localization framework is arranged. In this paper, a new mathematic calculation for the robot confinement framework utilizing light sensors is proposed. This procedure takes care of the issue of localization (position recognizing) when utilizing a grid of LEDs distributed uniformly in the environment, and a multi-portable robot outfitted with a multi-LDRs sensor and just two of them activate the visibility robot. The proposed method is utilized to assess the robot's situation by drawing two virtual circles for each two LDR sensors; one of them is valid and the other is disregarded according to several suggested equations. The midpoint of this circle is assumed to be the robot focus. The new framework is simulated on a domain with (n*n) LEDs exhibit. The simulation impact of this framework shows great execution in the localization procedure.

This paper proposes a low-cost Light Emitting Diodes (LED) system with a novel arrangement that allows an indoor multi-robot localization. The proposed system uses only a matrix of low-cost LED installed uniformly on the ground of an environment and low-cost Light Dependent Resistor (LDR), each equipped on bottom of the robot for detection. The matrix of LEDs which are driven by a modified binary search algorithm are used as active beacons. The robot localizes itself based on the signals it receives from a group of neighbor LEDs. The minimum bounded circle algorithm is used to draw a virtual circle from the information collected from the neighbor LEDs and the center of this circle represents the robot’s location. The propose system is practically implemented on an environment with (16*16) matrix of LEDs. The experimental results show good performance in the localization process.

The aim of this paper is to design and construct an over voltage protection system for a smart home. This system is designed to control the operation of a multi-device according to their priority and the amount of current allowed to be used for each home. The important part of the system is the main control unit, which receives the readings of the devices by using current sensors -one for each device. The algorithm used for controlling the operation of each device is implemented in software using the Visual Basic program, to show the principle of the operating system. Furthermore, the system is constructed on an Arduino microcontroller and several current sensors to measure the current drawn by each device. The same algorithm which is implemented in the software is applied to the microcontroller to save the energy drawn by the devices. The control system designed is tested in several experiments to show its performance. General TermsSmart home, over voltage system.
