2. Introduction
AEVs are small (< 500grams), autonomous, electric motor-powered, propeller-driven vehicles that are suspended from and maneuver along a monorail track systems hung from the laboratory ceilings
Example AEV
Introduce the concept of Advanced Energy Vehicles (AEVs), described above, and the design/build project. Refer to the Grand Challenges: Alternative energy sources, and the research and development to harness and use the energy efficiently is on the top of the list of the Grand Challenges for Engineers of the 21st Century – as determined by a committee of the National Academy of Engineering.
The overall objective for the AEV design/build project is to introduce the students the concepts of energy efficiency and energy management through the team oriented multidisciplinary design and operation of a small autonomous vehicle.
Three (3) awards are presented for BEST ENGINEERED, MOST INNOVATIVE, and BEST PROJECT DOCUMENTATION.

3. Project Objectives Project Management and Teamwork
Time management, task scheduling, communication, etc.
Design Process and Cycle
Indentifying requirements/constraints, brainstorming, initial designs, build/test/analyze, final design, etc.
Project Documentation
Project notebook, design review phase documents, final reports, extra credit video, etc.
There are three (3) main objectives to the AEV project.
Each are discussed in the following slides.
Additional details can be found in the Project Description Document.

4. Project Management and Teamwork
To successfully bring any complex project to completion requires proper planning and the coordinated effort of a group of people
Expected to produce related documents such as a project schedule and team meeting records, all of which must be regularly updated and kept in the team project notebook (discussed next week)
Additional information is included in the Project Description Document
To successfully bring any complex project to completion requires proper planning and the coordinated effort of a group of people. To help your team achieve this goal, you will be introduced to the basics of project management and teamwork. This includes, but is not limited to: time management and task scheduling, team communications and meetings, fair division of labor and team member responsibilities.
Student teams will be expected to produce related documents such as a project schedule and team meeting records, all of which must be regularly updated and kept in the team project notebook.
Additional information is included in the Project Description Document.

5. Design Process and Cycle
Process includes: identifying the project requirements and constraints, gathering background information, brainstorming, identification and management of materials, preliminary analysis & initial design, and the build/test/modify/document cycle
As part of this process, you will brainstorm initial concepts of your AEV, produce a preliminary design of your AEV, document revisions as they occur, and produce a final paper design that accurately reflects your final AEV design
Review Engineering Design Process material from 1181
Teams will reach a useful design much sooner if they follow a more formalized approach to the design process.
Teams will brainstorm initial concepts of AEVs, produce a preliminary design, document revisions as they occur, and produce a final paper design that accurately reflects the final AEV design.
Documentation of all design iterations will be kept in a project notebook, including initial concepts and the final design.
Additional information is included in the Project Description Document and steps outlined in Tools and Tactics of Design reference text.
It is expected that students will review the Engineering Design Process material from 1181 mini-design project.

6. Project Documentation
Your project documentation consists of three parts: the team project notebook, the oral presentation and the final written report
The team project notebook is the complete documentation of the AEV project, which will be reviewed on a weekly basis. It should contain your lab documentation, paper design, team meeting minutes, project management documents, and anything else of importance relating to the AEV
Additional information is included in the Project Description Document
Documentation consists of three parts: the team project notebook, the oral presentation and the final written report.
The team project notebook is the complete documentation of the AEV project, which will be reviewed on a weekly basis. It should contain lab documentation, paper design, team meeting minutes, project management documents, and anything else of importance relating to the AEV. The final technical oral presentation is an overview of your AEV design. The final written report is a complete summary of all aspects of your design.
The requirements for each of these are described during the design project.
Other references are: Tools and Tactics of Design and A Guide to Writing as an Engineer.

7. AEV Video
In addition to the required documentation components, an AEV Video can be completed for up to 2% extra credit on your overall grade
Here is a short example video

10. Design Review Phases

11. AEV Design Review Phases
Demonstrate the design process through a series of review phases
A design review is described as a:
"documented, comprehensive examination of the design to evaluate the adequacy of the design requirements“
The Mission Concept Review (MCR) is an example of an early review phase; and, in this case, is provided.
Review definition provided above.
Design review phases are used, to various degrees, within industry and department of defense components
The most commonly known are the Preliminary Design Review and the Critical Design Review.
The review phases relevant to, and important for, the AEV project are listed on the following slides.

12. AEV Design Review Phases Procedure
AEV design teams will demonstrate the design by:
Developing Test Readiness Review Documents to demonstrate that the team is prepared to meet the Performance Test Objectives
Developing a Preliminary Design Review Document from laboratory tests and Performance Test 1
Developing a Critical (Final) Design Review Document from detailed investigations in design, including the PDR, and Performance Tests 2-4
The Preliminary Design Review (PDR) and the Critical Design Review (CDR) are the major milestones for the AEV project.
Each are worth 12.5% of the project grade.
The Project Notebook and its content will be the primary judging criteria for BEST PROJECT DOCUMENTATION.
