Most wheeled mobile robot (WMR) controllers have been developed based on nonskidding and nonslipping assumptions. Unfortunately, wheel skidding and slipping are inevitable due to wheel tire-deformation; consequently, the stability and performance of these controllers are not guaranteed. This brief aims to develop a global positioning system (GPS)-based path following a controller for a car-like wheeled mobile robot in the presence of wheel skidding and slipping. The proposed control scheme uses real-time kinematic (RTK)-GPS and other aiding sen ....etc

1. INTRODUCTION

GLOBAL Positioning System (GPS) receivers for the consumer market require solutions that are compact, cheap, and low power. Manufacturers of cellular telephones, portable computers, watches, and other mobile devices are looking for ways to embed GPS into their products. Thus, there is a strong motivation to provide highly integrated solutions at the lowest possible power consumption. GPS radios consist of a front-end and a digital baseband section incorporating a digital processor. While for the baseband processor, cost-reduc ....etc

Introduction

Overview

Coronary artery disease, the restriction of blood flow to the heart, is the leading cause of death in the United States. The chances of suffering a myocardial infarction are great and increase up to fifteen times after the first occurrence. During a heart attack, heart muscle is depraved of oxygen and will literally die if the artery remains blocked. The first few hours are critical in saving much of the dying heart muscle and preventing permanent heart damage. Unfortunately, the symptoms vary and the most common ....etc

In this modern, fast moving and insecure world, it is become a basic necessity to be aware of oneâ„¢s safety. Maximum risks occur in situations wherein an employee travels for money transactions. Also the Company to which he belongs should be aware if there is some problem. What if the person traveling can be tracked and also secured in the case of an emergency?! Fantastic, isnâ„¢t it? Of course it is and hereâ„¢s a system that functions as a tracking and a security system. Itâ„¢s the VMSS. This system can deal with both pace an ....etc

Real-Time Positioning Technology Fleet management system is a rapid growing industry. This system helps institutions to manage vehicle fleet efficiently and effectively through smart allocation of resources. In this project, an intelligent fleet management system which incorporates the power of concurrent Global Positioning System (GPS) and Global System for Mobile Communications (GSM) real-time positioning, front-end intelligent and web-based management software is proposed. In contrast to systems which depend solely on GPS positioning, the pr ....etc

This paper presents a Tele-monitoring and management system for inter-cities transportation vehicles such as taxis and buses. The system is based on a stand-alone single-board embedded system that is equipped with GPS and GSM modems that is installed in the vehicle. A personal computer based GSM-Server is installed at transportation's head-quarter. While the vehicle is on the move, its real-time parameters such as speed, location, estimated arrival time, road condition and surrounding weather status are reported as SMS message to the transporta ....etc

Assisted GPS works by providing a GPS reference network in which a series of receivers have a clear view of the sky and can operate continuously. This reference information is then made available to cellular networks such as GSM and UMTS to refine location accuracy within the sphere of location based services. This module discusses the interaction between the reference network and the Location functions within a cellular network and how these combine to offer accurate location information. ....etc
