February 2015

ABSTRACT :The purpose of this project is to design a vehicle that is able to encounter gravity forces that will lead it into an unbalanced state , this vehicle will be stable in all statues (standing still or in motion ) using an opposite force to encounter any tilting angle which is produced by the control momentum gyroscope. Angular momentum will be generated by a DC motor that rotates a disk in one speed. The second task in this project was to control the motion of the vehicle in many speeds by using a micro-controller to use the PWM technique and generate a binary signal for better speed control of the vehicle. A motor driver to control the direction of rotation of the movement motor to drive the vehicle forward or backward. Third task was to control the vehicle wirelessly, a Bluetooth circuit connected to micro- controller to change the speed and enable the vehicle to go forward and backward, and this done by using mobile application.

ABSTRACT:Branch-Line Microstrip Coupler is one of the fundamental components in RF/Microwave systems. It is a 4-Port device that divides and/or combiner power simultaneously. These features make the coupler extremely useful in various applications (GSM-Band), such as antenna feeding network, phase shifter, balance amplifier and mixer. In this project theoretical study was carried out on the characteristic of Microstrip Directional Couplers included, Isolation, Coupling, through and Directivity, which are important quantities for characterization of couplers. The AWR Program was used to establish the design of the Microstrip Coupler Circuit using element browser. Measurements S-Parameters of Microstrip Coupler Circuit were conducted and Spectrum Analyzer was used for this purpose. Although Spectrum Analyzer was used for measurements Transmission Coefficients, Coupling, Isolation, Directivity and Reflection Coefficients. Measurement errors due to tracking frequency response and mismatching in this conducted project were considered.

ABSTRACT :Uda Yagi antenna design for transmit or receive electromagnetic energy the at 500 MHz resonance frequency and 40Mhz bandwidth and its directional antenna consisting of multiple parallel elements in a line in a half-wave long consist of a single driven element connected to the transmitter or receiver with a transmission line, and reflector and four directors supported on a boom(6 elements ) we designed the Yagi , test it , take the measurements and simulations it by using antenna magus.

2D Scanner

ABSTRACT:This project idea started with an educational concept. No one will argue that a laser scanner is state of the art, and more accurate. But this project aim was to learn how to use simple components as low cost sensors, using the components and devices available in the market, and to build the scanner at the lowest cost possible.

2D Scanner is a contact scanner, in which a probe touches the outer dimension of the scanned object, consequently measuring its external dimensions.

The basic idea was to fix the scanned object on a rotating platform, measuring the outer surface. Then rotating the platform one step, using a stepper motor, measuring the outer dimension again, and repeating this step until, the whole outer dimension is scanned. This phase, would finish the scanning process. And the collected data is stored in the scanner memory. But it will not enable a visual representation of the scanned object. Which is normally expected.

To visualize the scanned object, a computer was used to draw the outer perimeter of the scanned object. To achieve that, the stored data is transferred to the computer usingRS232 connection, then the computer has to calculate the errors due to the measurement process, then, the X and Y of each point. Finally, to draw and connect all the points.
