Advanced Energy Vehicle (AEV) Lab 00: 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 4
AEV Learning 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 Portfolio, design review phase documents, final reports, extra credit video, etc. 5
AEV Design Cycle
Problem Solving Method 1. Define Problem solving is an iterative process. At any point you may need to 2. Represent go back to a previous step (even the beginning!) and re-work the problem. 3. Plan 4. Implement 5. Evaluate Reworking the problem will provide a better solution than rushing through the steps. Your first solution may not be your best solution! See Lecture 02 from ENGR 1181 for more in depth description of DR PIE 7

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. 9
AEV Design Review Phases Procedure 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 10

DEFINE: Mission Concept Review (MCR)
DEFINE: Mission Concept Review Background: Galactic Empire is rebuilding their army after the destruction of the Death Star Rebel alliance needs to prepared Construction is done on remote planets Power very limited Alliance using a monorail system to transport newly constructed R2D2 units from one side of the planet to the interceptor aircrafts Giphy.com 13
Vehicle Constraints 1. The AEV must traverse along a monorail track system. 2. The AEV must be able to operate both forward and backward along the monorail track system. 3. The main propulsion system must be air driven (propeller) and hang below the track system. 4. The vehicle must utilize provided Li-PO batteries to supply the power to the electric motors. 5. The Arduino Controller must not be placed on the vertical support arm. 6. There must be a clearance area of two by two inches between the Arduino Controller and the caboose connection (magnet). The front of the AEV will have a mating erector set part similar to the bracket shown below, but without a magnet. The Caboose will initially be positioned the entrance of the junkyard. 14
Front of Classroom Track is split into 4 parts Outside Right (Green) Inside Right (Purple) Outside Left (Blue) Inside Left (Red) Scenario is the same for all, just different distances 15

PLAN: Brainstorming Activity
Connecting the components to AEV Now that the problem has been defined, and you have represented the components of the AEV, brainstorm the design plan. As a group, on each sticky note write one thing that may be tested, designed and modified for your AEV. 27
