Omnidirectional robotic platform : the control of an omnidirectional robotic platform for use in robot soccer
… replacing their differential drive robots with omnidirectional robots – robots which can move in any direction without first changing their orientation to face the direction of motion. These robots have proved to be highly manoeuvrable and the winning teams in the small robot league are …

Omnidirectional obstacle detection using minimal sensing
… (drones) is introduced. The approach achieves omnidirectional detection of obstacles via suitable synergy of hardware and software. The drone requires a specific arrangement of two cameras, opposing each other, and placed below and above the drone. A total coverage of the drone's surroundings …

Omnidirectional Vision for an Autonomous Surface Vehicle
Due to the wide field of view, omnidirectional cameras have been extensively used in many applications, including surveillance and autonomous navigation. In order to implement a fully autonomous system, one of the essential problems is construction of an accurate, dynamic environment model. In …

Geolocation of Utility Assets Using Omnidirectional Ground-Based Photographic Imagery
A process for using ground-based photographic imagery to detect and locate power distribution assets is presented. The primary feature of the system presented here is it's very low cost compared to more traditional inspection methods because the process takes place entirely in virtual space. …

Size-binary Zincblende: A Colloidal Approach to Omnidirectional Photonic Bandgaps
Binary colloidal mixtures have the potential to greatly expand the range of mesoscale structures fabricated by self-assembly, putting them at the frontier of the realization of novel photonic crystals. Currently, it is not understood how the multicomponent basis and particle size ratio of binary …

Significance of omnidirectional fisheye cameras for feature-based visual SLAM
… well below 180 degrees. However, cameras with omnidirectional fisheye lenses can see much more of their surroundings, which suggests they may be beneficial for the visual SLAM task; this hypothesis is supported by the trend that recent commercial products that rely on robust visual navigation …

Development and Execution of a Testing Strategy for Omnidirectional Wheels
Omnidirectional wheels enable robots to achieve holonomic motion; however, this often comes at the cost of increased rolling resistance compared to traditional caster wheels. The rolling resistance in omnidirectional wheels is higher than in many other wheels due to several factors including an …

Wide-area egomotion from omnidirectional video and coarse 3D structure
This thesis describes a method for real-time vision-based localization in human-made environments. Given a coarse model of the structure (walls, floors, ceilings, doors and windows) and a video sequence, the system computes the camera pose (translation and rotation) in model coordinates with an …

6.78MHz Omnidirectional Wireless Power Transfer System for Portable Devices Application
… and covers all the directions in 3D space. With omnidirectional magnetic field, the charging platform can provide energy transfer in any direction; therefore, the angle alignment between the transmitter coil and receiver coil is no longer needed. Compensation networks are normally used to improve …

Vision-based Navigation and Mapping Using Non-central Catadioptric Omnidirectional Camera
Omnidirectional catadioptric cameras find their use in navigation and mapping, owing to their wide field of view. Having a wider field of view, or rather a potential 360 degree field of view, allows the user to see and move more freely in the navigation space. A catadioptric camera system is a low …

Omnidirectional view and multi-modal streaming in 3D tele-immersion system
… this thesis, we present systematic solutions of omnidirectional view in 3D tele-immersion system in a real-time manner and in an on-demand streaming manner, called FreeViewer and OmniViewer, respectively. we provide a complete multi-modal 3D video streaming/rendering solution, which achieves the …

Design of an omnidirectional soft tactile sensor with applications in leak detection
Soft robots have many unique geometries requiring different tactile feedback mechanisms. In order to respond to their environment, soft robots would benefit by having multi-axis sensors that can determine how a surface is being contacted. As a particular application, previous soft sensor designs …

Analysis, design, and control of an omnidirectional mobile robot in rough terrain
An omnidirectional mobile robot is able, kinematically, to move in any direction regardless of current pose. To date, nearly all designs and analyses of omnidirectional mobile robots have considered the case of motion on flat, smooth terrain. In this thesis, an investigation of the suitability of …

A Continuous-Time Nonlinear Observer for Estimating Structure from Motion from Omnidirectional Optic Flow
Various insect species utilize certain types of self-motion to perceive structure in their local environment, a process known as <italic>active vision</italic>. This dissertation presents the development of a continuous-time formulated observer for estimating structure from motion that emulates the …
