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 Project Objective (Problem Definition) AEV Design Cycle INITIAL CONCEPTS (Brainstorming) EXPERIMENTAL RESEARCH (Programming) (System Analysis) PT 1 PT 2 PT 3 PT 4 FINAL DESIGN Present AEV Design 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 Design Review Phases Overview Mission Concept Review (provided) Mission Concept Review (MCR) Test Readiness Review: Performance Test 1 Final Documentation Preliminary Design Review (PDR) Test Readiness Reviews: Performance Test 2-4: Critical Design Review (CDR) AEV Components AEV Components Classroom Components • Desktop Tracks • Li-PO Battery and Chargers These components are to stay in the classroom at ALL times AEV-Kit (kept by team) Automatic Control System Structure Pieces Hardware Electric Motors Propellers Monorail wheels Hand Tools AEV Components Tracks: • Classroom (overhead) • Desktop Desktop Track Each desk has a desktop stand to use throughout the AEV design process Classroom Track The laboratory has suspended track(s) for design and operational testing AEV Components AEV Structure and Wheels AEV AEV structure Structure and Wheels AEV Wheel AEV Reflective Sensor Propulsion System Energy Storage Automatic Controller Motor Driver Aerodynamic Bodies AEV Components AEV Propulsion System Brushless Electric Motor AEV Structure and Wheels Propulsion System 2.5” and 3”, Diameter Propellers Energy Storage Automatic Controller Motor Driver Aerodynamic Bodies AEV Components AEV Energy Storage AEV Structure and Wheels Propulsion System Energy Storage 2-Cell Lithium-Polymer Battery Capacity: 800mAh Voltage: 7.4V (nominal) Automatic Controller Motor Driver Aerodynamic Bodies AEV Components AEV Automatic Control System Arduino Nano USB AEV Structure and Wheels Propulsion System Energy Storage Automatic Controller Motor Driver Aerodynamic Bodies Motor Driver AEV Components AEV Aerodynamic Body Components OPTIONAL OPTIONAL components AEV for AEV Design Home-built or Team Bought Innovative thought encouraged Structure and Wheels Propulsion System Energy Storage Automatic Controller Motor Driver Aerodynamic Bodies AEV Components AEV Aerodynamic Body Components OPTIONAL AEV Structure and Wheels Propulsion System Energy Storage Automatic Controller Motor Driver Aerodynamic Bodies 3D Printing Laser Cutting Mission Concept Review 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)
