The utility of micro air vehicles (MAVs) has expanded significantly in the last decade, and
there are now numerous commercial systems available at relatively low cost. This expansion …

Positioning systems have become increasingly popular in the last decade for location-based
services, such as navigation, and asset tracking and management. As opposed to outdoor …

In this paper, an ultrasonic positioning system is presented and characterized, based on the
usage of a portable grid of beacons and of a few fixed anchors. Since the beacon grid can …

In recent years, lightweight, inexpensive, vessel-mounted 'recreational grade'sonar systems
have rapidly grown in popularity among aquatic scientists, for swath imaging of benthic …

Glacial lake outburst floods (GLOFs) are a severe hazard in the Himalayas. Glacial lake
expansion and the corresponding volume increase play major roles in GLOFs as well as …

Research on autonomous vehicles (AV)-self-navigating machines that transport both man
and cargo has proliferated lately. While once limited to industrial or military uses, more …

The goal of this study is to generate high-resolution sea floor maps using a Side-Scan Sonar
(SSS). This is achieved by explicitly taking into account the SSS operation as follows. First …

Purpose The purpose of this research is to provide the necessarily and resourceful
information regarding range sensors to select the best fit sensor for robust autonomous …

Deep reinforcement learning (RL), where the agent learns from mistakes, has been
successfully applied to a variety of tasks. With the aim of learning collision-free policies for …

This paper presents a novel approach to mobile robot localization using sonar sensors. This
approach is based on the use of particle filters. Each particle is augmented with local …
