1. ‘Mjolnir’ External/Internal Search and Concept Evaluation Tad Bamford Ben Higgins Chris Schultz Aaron Stanton Neal Pang

2. Overview  External Search o Product Research o Fabrication Research  Internal Search o Brainstorming/Concept Generation  Concept Evaluation/Selection o Decision Matrix

3. External Search  Product Research HPVs from previous competitions ○ Performance advantages ○ Current innovative technology ○ Documented findings HPVs available for purchase ○ Robust manufacturing techniques ○ Conventional design/configuration Hobbyist HPVs ○ Personal experience ○ Common failures

4. External Search  Fabrication Research Frame ○ Available materials ○ Available tools/processes Drive train ○ Advantages/disadvantages of component configuration Controls ○ Modifiable commercial parts Steering equipment Wheels/Brakes

5. Internal Search  Brainstorming Strive for innovation ○ Energy storage device ○ Leaning Frame/dynamic camber system ○ Sectional fairing ○ Unconventional/sustainable materials  Concept Generation Produced from PDS criteria Judged by decision matrix
