Program of Study

The main emphasis of the Ph.D. program is the successful completion of an original and independent research thesis. The degree requirements are designed around this goal.

Minimum Requirements

  • Completion of 36 semester hours of courses with a letter grade
  • Passing a comprehensive qualifying exam with written and oral components.
  • Successfully conducting, documenting, and defending a piece of original research culminating in a doctoral thesis.
  • PLEASE NOTE: AI and Autonomy can no longer be chosen together as areas. You may still choose either AI or Autonomy as a core area, with a corresponding qualifier and core classes. The Autonomy and AI electives have been combined, so anyone who selects AI or Autonomy may choose electives from either area.

New Courses

Three new required courses are designed specifically for the Robotics Ph.D.:

Course
Details
CS/AE/ECE/ME 7785
Introduction to Robotics Research

Provides students with a familiarization of the core areas of robotics including: Mechanics, Control, Perception, Artificial Intelligence, and Autonomy. Provides an introduction to the fundamental mathematical tools required in robotics research. (3 credit hours).

The desired learning outcome is to provide a strong theoretical foundation for students on the multidisciplinary subject matters found in robotics. This is accomplished by:

  1. Providing an introduction to the fundamentals of robotics in the core areas of mechanics, control, perception, artificial intelligence, and autonomy.
  2. Providing the basic theoretical and mathematical tools to support the core areas in robotics.
  3. The evaluation component includes:
  • Mid-term and final exams to evaluate student understanding of course material.
  • Written homework assignments to reinforce and apply lecture materials.
  • Group project and presentation to apply theoretical understanding to real-world applications.

CS/AE/ECE/ME 8750
Multidisciplinary Robotics Research I
(3 credit hours)
Prerequisite: CS/AE/ECE/ME 7785

CS/AE/ECE/ME 8751
Multidisciplinary Robotics Research II
(3 credit hours)
Prerequisite: CS/AE/ECE/ME 8750

These courses form a two semester sequence with similar “laboratory-rotation” formats. Each course requires the student to complete a semester-long research project under the guidance of at least two faculty members from distinct participating schools (AE, BME, CoC, ECE, or ME). The courses are designed to expose students to the discipline of research in a structured way and to encourage novel ideas in a multidisciplinary context.

The desired learning outcome is to foster a multidisciplinary research approach in the student by:

  • Critically assessing the prior art in an area outside his/her own,
  • Performing state-of-the-art experimental or simulation work in a multidisciplinary area,
  • Coherently reporting, at the level of a conference publication, on the research performed.

The evaluation component includes:

  • Week 2, a one page proposal outlining the proposed work along with a well-argued motivation;
  • Week 5: a detailed written review paper of the state-of-the art in the area;
  • Week 10: a written report on the experimental or simulation component in progress;
  • Week 14: a final report and presentation that includes all of the above along with a discussion of the work done and opportunities for future work.

All deliverables will be graded by both faculty advisors as well as reviewed to comply with the evaluation criteria set by the Robotics Program Committee.

Qualifying Exam

The purpose of the comprehensive exam is to:

  • Assess the student's general knowledge of the degree area
  • Assess the student's specialized knowledge of the chosen research area

The comprehensive examination provides an early assessment of the student's potential to satisfactorily complete the requirements for the doctoral degree. As such, it requires that fundamental principles be mastered and integrated so that they can be applied to solving problems relevant to robotics.

Procedure

After three regular semesters (Fall or Spring) from entering the Ph.D. program the student must take the comprehensive examination at the next scheduled offering, usually during the fourth regular (i.e. fall or spring) semester. If the comprehensive examination is failed, the student may have one additional opportunity at the next scheduled offering. The examination will be offered at least once every year.

The comprehensive exam is a written and oral examination and is administered by a faculty committee, selected by the thesis advisor in consultation with the student, and approved by the Robotics Program Committee. The committee consists of:

  • Three faculty members consistent with the student's graduate coursework and research area.
  • The thesis advisor as a non-voting observer.

Ph.D. Thesis

The Ph.D. dissertation describes the results of a research project and demonstrates that the candidate possesses powers of original thought, talent for research, and ability to organize and present findings.

Dissertation Advisory Committee

The student presents and defends a written Ph.D. proposal to a Dissertation Advisory Committee of at least five faculty members approved by the Robotics Program Committee. The Dissertation Advisory Committee consists of five or more members where:

  • At least three members must be faculty affiliated with the Robotics Program or from the student's Home School (CoC, AE, BME, ECE, ME).
  • At least two members must be from outside of the student’s Home School

Ph.D. Dissertation Proposal

The objective of the Ph.D. Proposal is to allow an early assessment of your chosen topic of research for the satisfactory completion of the doctoral degree. The proposal should delineate your specific area of research by stating the purpose, scope, methodology, overall organization, and limitations of the proposed study area. The proposal must include a review of the relevant literature and indicate the expected contribution of the research.

The proposal should be organized as follows:

  • Summary - limited to 200 words.
  • Table of Contents
  • Project Description - a clear statement of the work to be undertaken. Limited to 15 pages single spaced (30 pages double spaced) and including all graphic elements and tables.
  • Bibliography

Pages should be of standard size (8½" x 11"; 21.6 cm x 27.9 cm) with minimum 1" or 2.5 cm margins at the top, bottom, and on each side. The minimum type font size is 10 to 12 points.

Dissertation Defense

The dissertation, when completed, must be publicly defended before an Examination Committee approved by the Graduate Studies office. In most instances the Examination Committee is expected to be the same as the Dissertation Advisory Committee. If a candidate should fail to pass the final oral examination, the Examining Committee may recommend permission for one additional examination. It is expected that the dissertation results will be published in peer-reviewed journals and conferences.

Details on preparing and submitting a dissertation according to institute guidelines are available on the Graduate Admissions website.

Residency Requirement

“Doctoral students must spend at least two full-time semesters in residence at the Georgia Institute of Technology and ordinarily must complete research for the dissertation while in residence.” (Georgia Tech 2009-10 General Catalog)
