Development Of An End-Effector Sensory Suite For A Rehabilitation Robot, Stephanie A. Stiber Jul 2006

Development Of An End-Effector Sensory Suite For A Rehabilitation Robot, Stephanie A. Stiber

Graduate Theses and Dissertations

This research presents an approach in assisting the control and operation of a rehabilitation robot manipulator to execute simple grasping tasks for persons with severe disabilities. It outlines the development of an end-effector sensory suite that includes the BarrettHand end-effector, laser range finder, and a low cost camera.

The approach taken in this research differs greatly from the currently available rehabilitation robot arms in that it requires minimal user instruction, it is easy to operate and more effective for persons severely disabled. A thorough study of the currently available systems; Manus, Raptor and Kares II arm, is also presented.

A Mechanized Horseback Riding Simulator As An Aid To Physical Therapy, Jennifer Lott Jul 2006

A Mechanized Horseback Riding Simulator As An Aid To Physical Therapy, Jennifer Lott

Graduate Theses and Dissertations

Equine-assisted therapy is a nontraditional form of physical therapy that involves riding horses as a form of rehabilitation. Limited access to these riding programs justifies a need to develop a horseback riding simulator capable of simulating the gaits, bend, and collection of the horse. Research involving the development of horseback riding simulators is limited, but the available research does show promising results in the ability to aid in physical therapy.

A two-dimensional model and simulation was developed using MATLAB. Using the results from the simulation, a horseback riding simulator was designed, fabricated and tested. The physical simulator was capable of ...


Detection Of Cracks In Single-Crystalline Silicon Wafers Using Impact Testing, Christina Hilmersson Mar 2006

Detection Of Cracks In Single-Crystalline Silicon Wafers Using Impact Testing, Christina Hilmersson

Graduate Theses and Dissertations

This thesis is about detection of cracks in single-crystalline silicon wafers by using a vibration method in the form of an impact test. The goal to detect cracks from vibration measurements introduced by striking the silicon wafer with an impact hammer. Such a method would reduce costs in the production of solar cells. It is an inexpensive, relatively simple method which if commercialized could be used as an efficient in-line production quality test.

A hammer is used as the actuator and a microphone as the response sensor. A signal analyzer is used to collect the data and to compute frequency ...
