  • Leonard and Durrant-Whyte [1991] summarized the problem of navigation by three questions: "where am I?", "where am I going?", and "how should I get there?" This report surveys the stateof- the-art in sensors, systems, methods, and technologies that aim at answering the first question, that is: robot positioning in its environment.

  • Leonard and Durrant-Whyte [1991] summarized the general problem of mobile robot navigation by three questions: “Where am I?,” “Where am I going?,” and “How should I get there?.” This report surveys the state-of-the-art in sensors, systems, methods, and technologies that aim at answering the first question, that is: robot positioning in its environment. Perhaps the most important result from surveying the vast body of literature on mobile robot positioning is that to date there is no truly elegant solution for the problem.

  • Gyroscopic precession is a key factor involved in the concept of operation for the north-seeking gyrocompass, as will be discussed later. Friction in the support bearings, external influences, and small imbalances inherent in the construction of the rotor cause even the best mechanical gyros to drift with time. Typical systems employed in inertial navigation packages by the commercial airline industry may drift about 0.1 during a 6-hour flight [Martin, 1986]. 2.1.

  • In editions of Rory’s previous book iPhone and iPad Apps for Absolute Beginners (Apress), there were only two ways to teach the reader how to make an iOS app user interface. The first was to write everything in code, and the other was to use Interface Builder to compose a Windows-based app. But things have changed with Storyboarding … boy, have they! Storyboarding first appeared with Xcode version 4.2. When we first saw the scenes that made up an app, we thought Storyboard was fantastic. It was wonderful how Storyboard allowed us to navigate a path through out app in a visual way.

  • The idea of this book on Sensor fusion and its Applications comes as a response to the immense interest and strong activities in the field of sensor fusion. Sensor fusion represents a topic of interest from both theoretical and practical perspectives. The technology of sensor fusion combines pieces of information coming from different sources/sensors, resulting in an enhanced overall system performance with respect to separate sensors/sources.

  • This book is meant to be interesting, helpful, and educational to hobbyists, students, educators, and midlevel engineers studying or designing mobile robots that do real work. It is primarily focused on mechanisms and devices that relate to vehicles that move around by themselves and actually do things autonomously, i.e. a robot. Making a vehicle that can autonomously drive around, both indoors and out, seems, at first, like a simple thing.

  • Various methods for controlling mobile robot systems have been developed which are generally classified into two categories: global planning and local control. Many works, based on the complete knowledge of the robot and the environment, use a global planning method such as artificial potential fields [11], connectivity graph, cell decomposition [12], etc. These methods build some paths (set of sub-goals) which are free of obstacles

  • Other Wireless Systems The two major applications of RF and microwave technologies are in communications and radar=sensor systems. Radar and communication systems have been discussed in Chapters 7 and 8, respectively. There are many other applications such as navigation and global positioning systems, automobile and highway applications, direct broadcast systems, remote sensing, RF identi®cation, surveillance systems, industrial sensors, heating, environmental, and medical applications. Some of these systems will be discussed brie¯y in this chapter....

  • Manufacturing companies deploy sensors in their products to return a stream of telemetry. Sometimes this is used to deliver services like OnStar, that delivers communications, security and navigation services. Perhaps more importantly, this telemetry also reveals usage patterns, failure rates and other opportunities for product improvement that can reduce development and assembly costs. The proliferation of smart phones and other GPS devices offers advertisers an opportunity to target consumers when they are in close proximity to a store, a coffee shop or a restaurant.

  • The demand of vehicle navigation and guidance has been urgent for many years. The idea of integrating multisensor navigation systems was implemented. The most efficient multisensor configuration is the system integrating an inertial navigation system (INS) consisting of MEMS based micro sensors and a global positioning system (GPS). In such system, the GPS is used for providing position and velocity whereas the INS for providing orientation. The estimation of the system errors is performed by a Kalman...
