  • A shared-autonomy heavy-lift assistive robot for manufacturing

    Creator:
    Finley, Taylor M.
    Abstract:
    Automating pick-and-place operations for large steel castings in a foundry is challenging, particularly from a perception point of view. Accurately estimating the identity and orientation of a given part is an open and complex problem, especially if that part sits in a bin of very similar parts. The problem is...

  • Design of a Biomass Feeding Robot for Controlled Cookstove Testing

    Creator:
    O'Boyle, Duncan
    Abstract:
    The purpose of this report is to detail the design and validation of a prototype robot that feeds biomass into a range of small household cookstoves at a programmable rate. Improved design and testing methods for the development of improved biomass cookstoves are needed to design stoves that alleviate the...

  • An approach to reduced-order modeling and feedback control for wave energy converters

    Creator:
    Shoori J., Hesam E.
    Abstract:
    Wave energy holds great promise to be part of the alternative energy portfolio that will provide independence from fossil fuels. As wave energy converter (WEC) technologies mature, designing effective control strategies to extract maximum energy, extend device life, coordinate WEC operation within an array, or mitigate negative impacts of a...

  • Geometric Chatter Stability Index for Milling and Modeling of Chip Pulling Effect

    Creator:
    Maulimov, Mukhtar
    Abstract:
    Prediction and mitigation of chatter vibrations in machining operations and optimizing overall machining mechanics are crucial for achieving greater productivity and manufacturing efficiency. This thesis first explores effect of directional relationships on chatter stability in milling process. Based on the directional relationships, a geometry-based chatter stability index (CSI) is proposed...

  • Interconnection Networks Based on Gaussian and Eisenstein-Jacobi Integers

    Creator:
    Shamaei, Arash
    Abstract:
    Quotient rings of Gaussian and Eisenstein-Jacobi(EJ) integers can be deployed to construct interconnection networks with good topological properties. In this thesis, we propose deadlock-free deterministic and partially adaptive routing algo­rithms for hexagonal networks, one special class of EJ networks. Then we discuss higher dimensional Gaussian networks as an alternative to...

  • Modeling, simulation, and analysis of two hydraulic power take-off systems for wave energy conversion

    Creator:
    Casey, Sean (Sean Michael)
    Abstract:
    Hydraulic power take-off (PTO) systems have been implemented in several wave energy converter (WEC) designs in recent years. Two popular hydraulic PTO configurations coupled to a point absorber hydrodynamic model are simulated in waves representative of an energetic sea state likely to be found in deep waters off the coast...

  • Robotic deburring

    Creator:
    James, Francis
    Abstract:
    Deburring of machined parts is a crucial task in the aerospace and automotive industry. This process is still performed manually to a large extent due to the unpredictability of burr formation as well as the complex interactions between the human arm and the workpiece. Poor ergonomics, repetitive stress and strain...

  • Grasping complex casting shapes with an underactuated parallel jaw gripper on an industrial robot

    Creator:
    Carpenter, Ryan Joseph
    Abstract:
    Steel foundries are in great need of automation as current operations involve many hazardous manual tasks. Automating foundry operations is very challenging due to the variety of tasks that must be performed on physical objects that vary significantly in size, shape, and weight. This thesis focuses on robotically automating the...
