Abstract: This project is described the modeling of steer by wire (SbW) technique that implement using DE1 board to control the positioning. The variable resistor and servomotor are uses as input and output respectively. The actual position of variable resistor is translated into analog voltage signal using voltage divider theorem. The analog signal later on is converted into 10-bit digital form using A/D converter embedded in the PIC16F873A. An output from A/D converter is connected to the DE1 GPIO port as an input to the controller. The VHDL code is used to program the FPGA on DE1 board. The controller algorithm is successfully translated into the VHDL code and the DE1 boards completely act as a controller for this project. As a result, the motor pointer can follow exactly the desired pointed by the variable resistor.

Abstract: This project involves the design and development of an autonomous mobile robot that can move in various motions using Mecanum wheels. The Mecanum wheels developed consist of fifteen rollers made from abacus beads. All Mecanum wheels are independently powered using four units of DC motors and gearbox system. The aim of this project is to build a robot, which is autonomous, and move according to what have been programmed. The functions are forward, reverse, right slide, left slide, diagonal, rotation and obstacles avoidance. All these functions are set up by using MPLAB IDE software. This robot is controlled by microcontroller PIC16F877A which use as the brain to control the robot movement. This robot has obstacles avoidance capability which the robot will avoid obstacles like walls and boxes. It is equipped with three IRsensors on the left, right and in front of the robot to detect any obstacles.
