Improved Microrobotic Control Through Image Processing And Automated Hardware Interfacing, Archit R. Aggarwal, Wuming Jing, David J. Cappelleri

The Summer Undergraduate Research Fellowship (SURF) Symposium

Untethered submilliliter-sized robots (microrobots) are showing potential use in different industrial, manufacturing and medical applications. A particular type of these microrobots, magnetic robots, have shown improved performance in power and control capabilities compared to the other thermal and electrostatic based robots. However, the magnetic robot designs have not been assessed in a robust manner to understand the degree of control in different environments and their application feasibility. This research project seeks to develop a custom control software interface to provide a holistic tool for researchers to evaluate the microrobotic performance through advance control features. The software deliverable involved two main …

A Comparative Study Of Underwater Robot Path Planning Algorithms For Adaptive Sampling In A Network Of Sensors, Sreeja Banerjee

School of Computing: Dissertations, Theses, and Student Research

Monitoring lakes, rivers, and oceans is critical to improving our understanding of complex large-scale ecosystems. We introduce a method of underwater monitoring using semi-mobile underwater sensor networks and mobile underwater robots in this thesis. The underwater robots can move freely in all dimension while the sensor nodes are anchored to the bottom of the water column and can move only up and down along the depth of the water column. We develop three different algorithms to optimize the path of the underwater robot and the positions of the sensors to improve the overall quality of sensing of an area of …

Stereo Vision System Module For Low-Cost Fpgas For Autonomous Mobile Robots, Connor Citron

Master's Theses

Stereo vision uses two adjacent cameras to create a 3D image of the world. A depth map can be created by comparing the offset of the corresponding pixels from the two cameras. However, for real-time stereo vision, the image data needs to be processed at a reasonable frame rate. Real-time stereo vision allows for mobile robots to more easily navigate terrain and interact with objects by providing both the images from the cameras and the depth of the objects. Fortunately, the image processing can be parallelized in order to increase the processing speed. Field-programmable gate arrays (FPGAs) are highly parallelizable …

A Brain Robot Interface For Autonomous Activities Of Daily Living Tasks, Don Indika Upashantha Pathirage

USF Tampa Graduate Theses and Dissertations

There have been substantial improvements in the area of rehabilitation robotics in the recent past. However, these advances are inaccessible to a large number of people with disabilities who are in most need of such assistance. This group includes people who are in a severely paralyzed state, that they are completely "locked-in" in their own bodies. Such persons usually retain full cognitive abilities, but have no voluntary muscle control.

For these persons, a Brain Computer Interface (BCI) is often the only way to communicate with the outside world and/or control an assistive device. One major drawback to BCI devices is …

Leveraging Area Bounds Information For Autonomous Multi-Robot Exploration, Tsung-Ming Liu, Damian M. Lyons

Faculty Publications

In this paper we propose an approach, the Space-Based Potential Field (SBPF) approach, to controlling multiple robots for area exploration missions that focus on robot dispersion. The SBPF method is based on a potential field approach that leverages knowledge of the overall bounds of the area to be explored. This additional information allows a simpler potential field control strategy for all robots but which nonetheless has good dispersion and overlap performance in all the multi-robot scenarios while avoiding potential minima. Both simulation and robot experimental results are presented as evidence.

Invariant Inferring And Monitoring In Robotic Systems, Hengle Jiang

School of Computing: Dissertations, Theses, and Student Research

System monitoring can help to detect abnormalities and avoid failures. Crafting monitors for today’s robotic systems, however, can be very difficult due to the systems’ inherent complexity and its rich operating environment.

In this work we address this challenge through an approach that automatically infers system invariants and synthesizes those invariants into monitors. This approach is inspired by existing software engineering approaches for automated invariant inference, and it is novel in that it derives invariants by observing the messages passed between system nodes and the invariants types are tailored to match the spatial, time, temporal, and architectural attributes of robotic …

Robotic Book Scanner, Tobias Samuel Elder, Cynthia Marie Wong

Computer Engineering

Digitizing books has been an issue tackled by companies to allow people to read off Kindles and iPads rather than the traditional paperback. Companies like Google have spent more than $1000 on machines to convert books into electronic copies readable on devices. Yet, not much effort has been made into the invention of an automatic book scanner for consumers. This project seeks to determine a cost-effective approach to robotic book scanning to create PDFs from physical books. This project serves as a proof of concept for a reasonably priced automatic book scanner accessible to consumers. Potentially, the device may be …

Analysis, Optimization, And Implementation Of A Uav-Based Wireless Power Transfer System, Andrew Mittleider

School of Computing: Dissertations, Theses, and Student Research

Wireless power transfer is rapidly advancing in its ability to efficiently transfer power to a variety of devices.

As the efficiency increases, more applications for these systems arise. Since magnetic resonant wireless power transfer can only transfer a small amount of power, most current applications only focus on powering low-powered devices.

Wireless Sensor Networks are composed of many low-powered nodes which currently require human interaction to remain powered. We propose recharging a low-powered Wireless Sensor Network (WSN) with a magnetic resonant wireless power transfer system attached to a quadrotor Unmanned Aerial Vehicle (UAV).

This thesis addresses three main challenges with …

Autonomous Aerial Water Sampling, John-Paul W. Ore

School of Computing: Dissertations, Theses, and Student Research

Obtaining spatially separated, high frequency water samples from rivers and lakes is critical to enhance our understanding and effective management of fresh water resources. In this thesis we present an aerial water sampler and verify the system in field experiments. The aerial water sampler has the potential to vastly increase the speed and range at which scientists obtain water samples while reducing cost and effort. The water sampling system includes: 1) a mechanism to capture three 20 ml samples per mission; 2) sensors and algorithms for safe navigation and altitude approximation over water; and 3) software components that integrate and …

The Design Of A Mobile, Animatronic Bald Eagle, Eric Burns

Phi Kappa Phi Research Symposium (Archived)

Modern animatronics are used as a tool to help engage audiences in realistic and entertaining experiences. Many animatronic figures are dynamic in movement, but static in mobility. The research presented covers the beginnings of mobile animatronic research. An animatronic bald eagle, Opportunity, was designed for that purpose. Animations for Opportunity are generated by integration of Arduino, Pololu Mini Maestro, and Hitec Servo Motors. Arduino receives signals from flex sensors which cause voltage variations when “flexed”. The 1:1 scale, animatronic eagle can be perched on the arm of an “actor” who simulates an eagle’s caretaker. The flex sensors are located within …

A Multi-Case Study Of Student Interactions With Educational Robots And Impact On Science, Technology, Engineering, And Math (Stem) Learning And Attitudes, Stephanie Holmquist

USF Tampa Graduate Theses and Dissertations

The demand for STEM trained workers continues to increase not only in the United States, but globally. Reports have indicated that the United States is not doing a good job encouraging students to pursue STEM oriented degrees. In particular, it has become increasingly important to emphasize STEM connections at an early level in order to encourage student career exploration as they continue their education. Educational robots represent a unique alternative to traditional methods, especially at the elementary level. Considering the use of educational robots have largely been ignored at this level, the purpose of this study was to describe the …

Eliminating Mutual Views In Fusion Of Ranging And Rgb-D Data From Robot Teams Operating In Confined Areas, Damian M. Lyons, Karma Shrestha

Faculty Publications

We address the problem of fusing laser and RGB-Data from multiple robots operating in close proximity to one another. By having a team of robots working together, a large area can be scanned quickly, or a smaller area scanned in greater detail. However, a key aspect of this problem is the elimination of the spurious readings due to the robots operating in close proximity. While there is an extensive literature on the mapping and localization aspect of this problem, our problem differs from the dynamic map problem in that it involves at one kind of transient map feature, robots viewing …

A Sensor Ontology For The Domain Of Firefighting Robots, Amy Renae Wagoner

Open Access Theses

Fires create thousands of dollars in damage and thousands of deaths each year. Firefighters risk their lives everyday and are often killed in action. Firefighting robots may be able to reduce the loss of lives and damage due to fires. Robots are often used for redundant tasks that require the consistency and efficiency of a machine. They are especially optimal for tasks that require strength that exceeds that of a typical human being or for environments that are hazardous to people. Robots' metallic exteriors are far more durable and easier to replace than flesh and blood, thus they are ideal …

Software Architecture And Development For Controlling A Hubo Humanoid Robot, Manas Ajit Paldhe

Open Access Theses

Due to their human-like structure, humanoid robots are capable of doing some complex tasks. Since a humanoid robot has a large number of actuators and sensors, controlling it is a difficult task. For various tasks like balancing, driving a car, and interacting with humans, real-time response of the robot is essential. Efficiently controlling a humanoid robot requires a software that guarantees real-time interface and control mechanism so that real-time response of the robot is possible. Addition- ally, to reduce the development effort and time, the software should be open-source, multi-lingual and should have high-level constructs inbuilt in it.
