This book is about programming your robot to do amazing things, whether it be detecting people's faces and other visual objects, navigating autonomously around your house, or responding to spoken commands. We will be using some of the most advanced
We describe a new formulation of appearance-only SLAM suitable for very large scale navigation. The system navigates in the space of appearance, assigning each new observation to either a new or previously visited location, without reference to metr
The WirelessHD specification defines a wireless protocol that enables consumer devices
to create a wireless video area network (WVAN) with the following characteristics:

The omni-directional reflection characteristics of one-dimensional photonic crystals composed of Ta2O5/MgF2 multi-quantum well (MQW) are studied using the transfer matrix method. An omni-directional reflector consisting of three and four Ta2O5/MgF2 M
A Compact, Omni-directional, Circularly Polarized Microstrip Antenna - Presentation of an omni-directional, circularly polarized antenna using a zero-order resonator with arc-shaped stubs
Multi-robot coordination (MRC) is a key challenge for complex artificial intelligence systems, and conventional wireless-communication-based MRC mechanisms that cannot be deployed in radio-frequency-limited environments. In this Letter, we present a
