Model Based Force Estimation And Stiffness Control For Continuum Robots, Vincent A. Aloi

Doctoral Dissertations

Continuum Robots are bio-inspired structures that mimic the motion of snakes, elephant trunks, octopus tentacles, etc. With good design, these robots can be naturally compliant and miniaturizable, which makes Continuum Robots ideal for traversing narrow complex environments. Their flexible design, however, prevents us from using traditional methods for controlling and estimating loading on rigid link robots.

In the first thrust of this research, we provided a novel stiffness control law that alters the behavior of an end effector during contact. This controller is applicable to any continuum robot where a method for sensing or estimating tip forces and pose exists. …

Connecting Islamic Technology And The History Of Robotics In Wikidata Via Wikidatabot, Anchalee Panigabutra-Roberts

UT Libraries Faculty: Other Publications and Presentations

My current study is on the connection between the history of robotics and Islamic technology. I focused on early Muslim inventors, such as al-Jazari, from Artuqid Dynasty of Jazira in Mesopotamia (modern day Iraq, Syria and Turkey) who is considered to be the father of robotics. He wrote the Book of Knowledge of Ingenious Mechanical Devices, the manuscript treaty published after his passing in 1206, translated by Donald R. Hill, a British engineer and scholar on Islamic technology, in 1974. The manuscript in Arabic (MS. Greaves 27) is archived at the Bodleian Library, University of Oxford, United Kingdom. In …

Dynamic In Vivo Skeletal Feature Tracking Via Fluoroscopy Using A Human Gait Model, William Patrick Anderson

Doctoral Dissertations

The Tracking Fluoroscope System II, a mobile robotic fluoroscopy platform, developed and built at the University of Tennessee, Knoxville, presently employs a pattern matching algorithm in order to identify and track a marker placed upon a subject’s knee joint of interest. The purpose of this research is to generate a new tracking algorithm based around the human gait cycle for prediction and improving the overall accuracy of joint tracking.

This research centers around processing the acquired x-ray images of the desired knee joint obtained during standard clinical operation in order to identify and track directly through the acquired image. Due …

Autonomous Android: Autonomous 3d Environment Mapping With Android Controlled Multicopters, Tate Glick Hawkersmith

Masters Theses

Autonomous robots are robotic platforms with a high degree of autonomy, programmed to perform various behaviors or tasks. They can either be semi-autonomous, only operable within the strict confines of their direct environment, or fully autonomous, capable of sensing and navigating their environments without any human interaction.

In this thesis, I focus on fully autonomous robotic platforms, specifically multicopters, controlled by an onboard Android-driven device, a widely available operating system for smartphones and tablets with over 1.4 billion active monthly users worldwide [Callaham 2015]. The main objective of this research is to create a plug and play solution for autonomous …

3d Robotic Sensing Of People: Human Perception, Representation And Activity Recognition, Hao Zhang

Doctoral Dissertations

The robots are coming. Their presence will eventually bridge the digital-physical divide and dramatically impact human life by taking over tasks where our current society has shortcomings (e.g., search and rescue, elderly care, and child education). Human-centered robotics (HCR) is a vision to address how robots can coexist with humans and help people live safer, simpler and more independent lives.

As humans, we have a remarkable ability to perceive the world around us, perceive people, and interpret their behaviors. Endowing robots with these critical capabilities in highly dynamic human social environments is a significant but very challenging problem in practical …

Modeling, Analysis, And Control Of A Mobile Robot For In Vivo Fluoroscopy Of Human Joints During Natural Movements, Matthew A. Young

Doctoral Dissertations

In this dissertation, the modeling, analysis and control of a multi-degree of freedom (mdof) robotic fluoroscope was investigated. A prototype robotic fluoroscope exists, and consists of a 3 dof mobile platform with two 2 dof Cartesian manipulators mounted symmetrically on opposite sides of the platform. One Cartesian manipulator positions the x-ray generator and the other Cartesian manipulator positions the x-ray imaging device. The robotic fluoroscope is used to x-ray skeletal joints of interest of human subjects performing natural movement activities. In order to collect the data, the Cartesian manipulators must keep the x-ray generation and imaging devices accurately aligned while …
