Enabling Shape Memory Alloys as Actuators for Robotics

Gurley, Austin (2017-11-27)

Does any existing technology provide a viable actuator for the high degree-of-freedom robots that will soon be ubiquitous in society? If a technology exists that is in any way superior to the electric motor for robotics – ...

Evaluation of Cooperative Navigation Strategies with Maneuvering UAVs

Pryor, Jacob (2021-07-27)

This thesis presents and evaluates cooperative navigation methods used to reduce navigation solution error growth between members of an unmanned aerial vehicle - unmanned ground vehicle (UAV-UGV) or all-UAV team when Global ...

An Experimental Evaluation of the Delta Operator in Digital Control

Eidson, Brandon (2010-07-19)

Interest in digital control systems has been on the rise over recent decades with the ever decreasing cost and increasing performance of microprocessors and the academic advancements in control theory. Although there are ...

An Experimental Exploration of Low-Cost Sensor and Vehicle Model Solutions for Precision Ground Vehicle Navigation

Salmon, Daniel (2015-12-08)

This thesis presents the use of a vehicle dynamic model (VDM) in conjunction with standard vehicle safety sensors to assist a low-cost Inertial Measurement Unit (IMU) and low-cost Global Positioning System (GPS) for fused ...

A Feature-based Solution for Kidnapped Robot Problem

Wei, Lei (2015-12-11)

The Kidnapped Robot problem in robotics commonly refers to a situation where an autonomous robot can’t locate itself against the map. It can be caused by external force when a robot is carried to an arbitrary place, or ...

A Feedback Linearization Approach for Panel Flutter Suppression with Piezolectric Actuation

Onawola, Oluseyi (2008-12-15)

A panel is subject to dynamic instability when induced aerodynamic loads under the supersonic/hypersonic environment result in a self-excited oscillation called panel flutter. The panel of an aircraft that flies at ...

GPS and Inertial Sensor Enhancements for Vision-based Highway Lane Tracking

Clanton, Joshua (2006-08-15)

For the past decade much research in the Intelligent Transportation Systems (ITS) community has been devoted to the topic of lane departure warning (LDW). A significant portion of highway fatalities each year are attributed ...

Graph-Based Relative Path Estimation Using Landmarks for Long Distance Ground Vehicle Following

Pierce, Dan (2022-12-08)

This dissertation presents a graph-based sensor fusion framework for the localization of automated ground vehicles for leader-follower path duplication. A specific focus is given to scenarios where the following distance ...

Hardware Acceleration for Pedestrian Dead Reckoning in Embedded Systems

Johnston, Benjimen (2022-04-25)

Hardware acceleration within embedded systems can potentially allow algorithms to meet real time requirements in devices where it was previously impossible. Though many algorithms have been developed targeting embedded ...

Hybrid Aerial and Ground-based Mobile Robot for Retail Inventory

Lyu, Yibo (2018-05-10)

Radio frequency identification (RFID) technology is increasingly used in retail stores and warehouses because it can help to improve the inventory process, enable automatic checkout, and reduce shoplifting. This dissertation ...

Incorporation of a Foot-Mounted IMU for Multi-Sensor Pedestrian Navigation

Pierce, Daniel (2016-04-29)

This thesis deals with pedestrian localization by way of multi-sensor fusion. A special focus is made on the use of a foot-mounted inertial measurement unit (IMU) and its incorporation into other pedestrian navigation ...

Internet Data Acquisition, Search and Processing

Neeli, Sandeep (2009-12-11)

Internet data acquisition from the Web is the process of extracting essential data from any web server. Semi-structured data present in the form of HTML web pages need to be extracted, converted into structured data before ...

Kalman Filter Based Tracking Algorithms For Software GPS Receivers

Lashley, Matthew (2006-12-15)

In this thesis several new Kalman filter based tracking algorithms for GPS software receivers are presented. Traditional receivers use Costas loops and Delay Lock Loops (DLL) to track the carrier and Pseudo-Random Noise ...
