Lab 01: AEV Project IntroductionAdvanced Energy Vehicle (AEV)

Introduction

Example AEV

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

AEV Project Objectives

Project Management and Teamwork• Time management, task scheduling, communication, etc.

Design Process and Cycle• Identifying 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.

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.

AEV Design Review Phases

AEV design teams will demonstrate the design by:

1. Understanding the Mission Concept Review (MCR) to create an AEV to complete mission objectives and to meet design constraints

2. Developing Test Readiness Review Documents (TRR) to demonstrate that the team is prepared to meet the Performance Test Objectives

3. Developing a Preliminary Design Review Document (PDR) from laboratory tests and Performance Test 1

4. Developing a Critical (Final) Design Review Document (CDR) from detailed investigations in design, including the PDR, and Performance Tests 2-4

AEV Lab Reporting Format

Technical Communication Guide The GRADING GUIDELINES for each lab which will tell

which type of report format to follow.

Follow the Technical Communications Guide (Tech Comm Guide) found on the EEIC Course Website.

Make sure to have the appropriate header or cover page with the necessary information!

Remember to use past tense, third person, and also spell check the document before handing in!

AEV Documents Page

• The AEV Documents Page includes many documents that will be used throughout the semester

• A Lab Manual is included that describes the activities associated with each lab.

• A Lab Guidelines document describes the reporting requirements for each lab.

• Today follow the description for Lab 1 in the Lab Manual• Assemble the sample AEV components

shown on the AEV documents page under  3D PDF of Sample AEV.

Today’s Activities

1. Team will construct sample model of AEV – without motors or electronics

2. Team will brainstorm ideas for modifications for their design

3. Each team member will prepare an orthographic sketch of their idea – example in Lab Manual

4. The team will produce an Executive Summary as described in the Lab Guidelines document for Lab 1 on the AEV Documents Page. Disregard cost and weight estimates.

5. Print kit parts list (2 copies) and kit label and bring to next week’s lab

Design Considerations1. Must move forward and backwards2. Energy usage should be minimized (weight,

aerodynamics, etc.)3. How many motors to use4. Should motors be pushing or pulling vehicle?5. What propellers should be used?6. How will vehicle position be determined and

controlled?7. Battery voltage variations8. Track independence (slight uphill, downhill

variations may cause coasting)
