This paper reviews and describes the state-of-the-art in localization of autonomous guided
vehicles (AGVs). The localization problem, the ability to accurately sense and estimate the …

A basic requirement for an autonomous mobile robot is its capability to elaborate the sensor
measures to localize itself with respect to a coordinate system. To this purpose, the data …

This paper introduces error eliminating rapid ultrasonic firing (EERUF), a new method for
firing multiple ultrasonic sensors in mobile robot applications. EERUF allows ultrasonic …

An active wide-beam sonar system that mimics the sensor configuration of echolocating bats
is described for applications in sensor-based robotics. Obstacles in a two-dimensional (2-D) …

[57] ABSTRACT A system and method for determining the position of an automatically
guided vehicle within a workspace is dis closed which operates by detecting sounds …

This thesis documents an experimental investigation into the map-building and exploration
capabilities of a mobile robot. A map enables a robot to predict the state of its environment …

Accurate estimates of mobile robot location, if available, can be used to improve the
performance of a vehicle dynamics control system. To this purpose, the data provided by …

The physical properties of acoustic sensors are exploited to obtain information about the
environment for sonar map building. A theoretical formulation for interpreting the sensor …

This paper presents a novel sonar sensor consisting of three transmitters and three
receivers that can localise and classify 3D targets into 16 different naturally occurring indoor …

Echolocating bats obtain three-dimensional images of their surroundings in complete
darkness by emitting sonar signals and evaluating returning echoes. When flying close to …
