Fuzzy Logic Control Of An Inverted Pendulum Robot, Kyle Reid
Fuzzy Logic Control Of An Inverted Pendulum Robot, Kyle Reid
Electrical Engineering
The inverted pendulum is a classical problem in controls. The inherit instabilities in the setup make it a natural target for a control system. Over the years it has been the benchmark for testing new and innovative control theories such as Fuzzy Logic. During the course of this project a software fuzzy logic controller was implemented using a PIC microcontroller. At the conclusion of the experiment an interesting realization was made about the nature of Fuzzy Logic and its applicability in the world of controls.
Exploring The Human Interactivity With A Robot To Obtain The Fundamental Properties Of Materials, William L. Christian
Exploring The Human Interactivity With A Robot To Obtain The Fundamental Properties Of Materials, William L. Christian
USF Tampa Graduate Theses and Dissertations
This research studies the way in which humans and robots interact with each other. When two humans are working together through a set of robotic devices, do they tend to work together or fight with each other more? In which Cartesian direction do they have the most difficulty? Does fighting drastically affect the performance of the team? Finally, what measures can be taken to promote better cooperation between humans and robots to ultimately allow humans to work just as comfortably with a robotic partner as with a human partner? This research answers these questions and provides an analysis of human-robot …
Scene Segmentation And Object Classification For Place Recognition, Chang Cheng
Scene Segmentation And Object Classification For Place Recognition, Chang Cheng
Doctoral Dissertations
This dissertation tries to solve the place recognition and loop closing problem in a way similar to human visual system. First, a novel image segmentation algorithm is developed. The image segmentation algorithm is based on a Perceptual Organization model, which allows the image segmentation algorithm to ‘perceive’ the special structural relations among the constituent parts of an unknown object and hence to group them together without object-specific knowledge.
Then a new object recognition method is developed. Based on the fairly accurate segmentations generated by the image segmentation algorithm, an informative object description that includes not only the appearance (colors and …
Multiple Robot Boundary Tracking With Phase And Workload Balancing, Michael Jay Boardman
Multiple Robot Boundary Tracking With Phase And Workload Balancing, Michael Jay Boardman
Master's Theses
This thesis discusses the use of a cooperative multiple robot system as applied to distributed tracking and sampling of a boundary edge. Within this system the boundary edge is partitioned into subsegments, each allocated to a particular robot such that workload is balanced across the robots. Also, to minimize the time between sampling local areas of the boundary edge, it is desirable to minimize the difference between each robot’s progression (i.e. phase) along its allocated sub segment of the edge. The paper introduces a new distributed controller that handles both workload and phase balancing. Simulation results are used to illustrate …
Cooperative Remote Sensing And Actuation Using Networked Unmanned Vehicles, Haiyang Chao
Cooperative Remote Sensing And Actuation Using Networked Unmanned Vehicles, Haiyang Chao
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This dissertation focuses on how to design and employ networked unmanned vehicles for remote sensing and distributed control purposes in the current information-rich world. The target scenarios are environmental or agricultural applications such as river/reservoir surveillance, wind profiling measurement, and monitoring/control of chemical leaks, etc. AggieAir, a small and low-cost unmanned aircraft system, is designed based on the remote sensing requirements from environmental monitoring missions. The state estimation problem and the advanced lateral flight controller design problem are further attacked focusing on the small unmanned aerial vehicle (UAV) platform. Then the UAV-based remote sensing problem is focused with further flight …
Design And Evaluation Of A Humanoid Robot For Autism Therapy, Daniel J. Ricks
Design And Evaluation Of A Humanoid Robot For Autism Therapy, Daniel J. Ricks
Theses and Dissertations
Recent evidence has shown that children with autism may behave more pro-socially when interacting with a robot than with a human. The objective of this research is to develop a robotic system for use in the clinical treatment of children with autism. The governing assumption behind this thesis is that using a robot in a clinic, under the guidance of a trained therapist, may lead to therapeutic benefits that may not be achieved without the presence of the robot. The robot Troy was developed to fulfill such a role in a clinical setting. The primary objective was to design a …
Robotic Goal-Based Semi-Autonomous Algorithms Improve Remote Operator Performance, Shawn Hunt
Robotic Goal-Based Semi-Autonomous Algorithms Improve Remote Operator Performance, Shawn Hunt
Wayne State University Dissertations
The focus of this research was to determine if reliable goal-based semi-autonomous algorithms are able to improve remote operator performance or not. Two semi-autonomous algorithms were examined: visual servoing and visual dead reckoning. Visual servoing uses computer vision techniques to generate movement commands while using internal properties of the camera combined with sensor data that tell the robot its current position based on its previous position. This research shows that the semi-autonomous algorithms developed increased performance in a measurable way. An analysis of tracking algorithms for visual servoing was conducted and tracking algorithms were enhanced to make them as robust …
