The Goddard Project

The goal of this project was to design and build a robotic dog modeled after Goddard from the 2001 television series, The Adventures of Jimmy Neutron Boy Genius. Sheet metal was used for the body of the robot in order to keep the frame lightweight. Goddard travels on two wheels powered by electric motors and two caster wheels. The robot utilizes a Raspberry Pi as its master device and an Arduino Uno in order to control the robot. Essentially, Goddard acts and behaves like an ordinary dog from barking, to moving around, to being a great companion and friend. In addition, Goddard also has access to the extensive knowledge of the Wolfram Alpha database and can be controlled over a wireless internet connection using a keyboard or voice controls. This project was successfully presented and demonstrated at the 2014 University of New Hampshire Undergraduate Research Conference and received an Award of Excellence

On the constraints defining BPS monopoles

We discuss the explicit formulation of the transcendental constraints defining spectral curves of SU(2) BPS monopoles in the twistor approach of Hitchin, following Ercolani and Sinha. We obtain an improved version of the Ercolani-Sinha constraints, and show that the Corrigan-Goddard conditions for constructing monopoles of arbitrary charge can be regarded as a special case of these. As an application, we study the spectral curve of the tetrahedrally symmetric 3-monopole, an example where the Corrigan-Goddard conditions need to be modified. A particular 1-cycle on the spectral curve plays an important role in our analysis.Comment: 29 pages, 7 eps figure

A model summer program for handicapped college students

During the summer of 1988, the Goddard Space Flight Center was the site of a new NASA project called A Model Summer Program for Handicapped College Students that was directed by Gallaudet University. The project's aim was to identify eight severely physically disabled college students (four from Gallaudet University and four from local historically black colleges and universities (HBCU's)) majoring in technical fields and to assign them technical projects related to aerospace which they would complete under the guidance of mentors who were full time employees of Goddard. A description of the program is presented

GREMEX update (Goddard research engineering management exercise)

Management simulation techniques offer training in management problems. Exercise was developed to provide experience in research and development project decision making from management rather than technological perspective. Program and documentation have been revised innumerable times in past. Described report is revised version as it exists to date

Evaluation of advanced geopotential models for operational orbit determination

To meet future orbit determination accuracy requirements for different NASA projects, analyses are performed using Tracking and Data Relay Satellite System (TDRSS) tracking measurements and orbit determination improvements in areas such as the modeling of the Earth's gravitational field. Current operational requirements are satisfied using the Goddard Earth Model-9 (GEM-9) geopotential model with the harmonic expansion truncated at order and degree 21 (21-by-21). This study evaluates the performance of 36-by-36 geopotential models, such as the GEM-10B and Preliminary Goddard Solution-3117 (PGS-3117) models. The Earth Radiation Budget Satellite (ERBS) and LANDSAT-5 are the spacecraft considered in this study
