Development Of A Miniature Pipe Crawler For Application In Fossil Energy Power Plants, Caique C. Lara
Development Of A Miniature Pipe Crawler For Application In Fossil Energy Power Plants, Caique C. Lara
FIU Electronic Theses and Dissertations
The power generation of fossil fuel power plants relies on burning coal to generate steam. The heat exchange between the water and burned coal occurs in the combustion chamber, which operates at a high pressure and temperature. Monitoring the integrity of the tubes inside the combustion chamber is a key factor to avoid failures. However, this is not an easy task as some areas are hard to reach and the pipeline commonly has a complex geometry. Moreover, the inspection is typically manual, external and the environment is hazardous for humans. This thesis presents the development and testing of an electrically …
Robot Control For Remote Ophthalmology And Pediatric Physical Rehabilitation, Melissa Morris
Robot Control For Remote Ophthalmology And Pediatric Physical Rehabilitation, Melissa Morris
FIU Electronic Theses and Dissertations
The development of a robotic slit-lamp for remote ophthalmology is the primary purpose of this work. In addition to novel mechanical designs and implementation, it was also a goal to develop a control system that was flexible enough to be adapted with minimal user adjustment to various styles and configurations of slit-lamps. The system was developed with intentions of commercialization, so common hardware was used for all components to minimize the costs. In order to improve performance using this low-cost hardware, investigations were made to attempt to achieve better performance by applying control theory algorithms in the system software. Ultimately, …
Design And Control Of A Dynamic And Autonomous Trackless Vehicle Using Onboard And Environmental Sensors, Scott R. Jagolinzer
Design And Control Of A Dynamic And Autonomous Trackless Vehicle Using Onboard And Environmental Sensors, Scott R. Jagolinzer
FIU Electronic Theses and Dissertations
The purpose of this thesis is to explore the current state of automated guided vehicles (AGVs), sensors available for the vehicles to be equipped with, control systems for the vehicles to run on, and wireless technology to connect the whole system together. With a technological push towards increasing automation and maximizing the possible throughput of systems, automated technology needs to improve for trackless and wireless systems such as vehicles that can be used to move loads in a vast array of applications.
The goal of this research is to develop and propose improvements in both vehicle and control system design …
Development Of A Body For A Pneumatic Crawler For Radioactive Waste Pipelines, Jose Alfonso Matos
Development Of A Body For A Pneumatic Crawler For Radioactive Waste Pipelines, Jose Alfonso Matos
FIU Electronic Theses and Dissertations
The goal of this thesis was to develop a body for a crawler robot to navigate DOE Hanford Site transfer pipelines in a timely fashion. Previous work in pipe crawlers was analyzed and different configurations were studied by this author in order to design a suitable device. Tests were done in CAD to verify the device would fit and be able to travel within the confines of the pipelines’3” inner diameter and 90° elbows with 4.25”radii. Pipelines in Hanford can transition into 2” pipe and this was also taken into consideration when selecting the dimensions for the device. Manufacturing methods …
