Transcript Lab 1 AEV Introduction

Advanced Energy Vehicle (AEV)
Lab 01: AEV Project Introduction
Introduction
AEVs are small (< 500grams), autonomous, electric motorpowered, propeller-driven vehicles that are suspended from
and maneuver along a monorail track systems hung from
the laboratory ceilings
Example AEV
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 Considerations
1. Must move forward and backwards
2. Energy usage should be minimized (weight,
aerodynamics, etc.)
3. How many motors to use
4. 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 variations
8. Track independence (slight uphill, downhill variations may
cause coasting)
