2. Agenda • Scope • What is Construction Challenge? • BHS and Construction Challenge • Regionals • Challenge • Results and Summary • Preparing for Nationals • Research and Brainstorming

3. Agenda (contd.) • Challenges for Nationals • Schematics and Givens • Early solutions • Prototyping • Testing and Results • Final Solution • Demonstration

4. Agenda (contd.) • Nationals Competition • Results and Summary • Nationals Video • Lessons Learned • Acknowledgements • Questions & Answers • Sources

5. Scope • “Gain experience in the construction and infrastructure industries.” -Construction Challenge • Work as teams to achieve a common goal • Use tech & math to solve real-world challenges

6. What is Construction Challenge? • Founded by Association of Equipment Manufacturers (AEM) and Volvo Construction Equipment (2007-2008) • Promote and replenish the shortage of eligible workers in construction and infrastructure. • Joined Destination Imagination (DI) 2008-09 • Challenges focus on local, national, and international infrastructure issues • Hands-on challenges

7. Bartlett High School’s Involvement • Construction Challenge at ConExpo/Con-Agg (2007-08) • Team BOMAG, 6th place • Construction Challenge at Knoxville, TN (2008-09) • First at regionals, middle at nationals • Construction Challenge at Knoxville, TN (2009-10) • 1st at all nationals, lower-middle at nationals

8. 2010-11 Construction Challenge Regionals Challenges • Transportation Infrastructure • Transport a ball through roads, tunnels, etc. • Water Infrastructure • Sort different size and colored balls into corresponding buckets • Local Infrastructure • Identify a local infrastructure issue • Present it and a solution to a Construction Challenge committee

9. 2010-11 Construction Challenge Regionals Results • 1st in Local Infrastructure • 2nd in Transportation Infrastructure • Did not place in Water Infrastructure • 4th place overall, final seat for Nationals • Domination (BHS) placed 1st overall at regionals

10. Preparing for Nationals: Research and Brainstorming • Research a variety of transportation methods • Tracks, tanks, and trailers • Real-world road conditions and solutions • Water infrastructure policies, bills, laws, and agencies • Develop questions for a game show challenge =

11. Challenges for Nationals

12. Early Solutions • Catapult with a detachable RC car base • Conveyor from Supply site to HQ build site • Tank-based RC vehicle • Deployable trailer Cost and size constraints were major factors in our final choice

13. Prototyping: Basics • Traxxas Stampede RC base • High acceleration • Miniature clutch system • Long battery life • Plexiglas car cover • High strength • Easily manipulated (cut, drilled, milled, etc.) • Provided materials by Construction Challenge

14. Prototyping: Trials • Containment system • String of various sizes • Scissor lift system • Suspension • Various ride heights • Increased/decreased shock resistance • Blocked suspension travel

15. Prototyping: Trials (contd.) • Wheelie bar • Prevented rollovers • Reduced containment string tangles • Aesthetically pleasing

16. Testing and Results

17. Test 1: Acceleration • Car needed to navigate course quickly • Stop-and-go strain had to be minimized • Timed how long the car took to cross 10ft sections • Calculated acceleration AND velocity • Adjusted motor gearing based on results

18. Test 1: Section vs. Time Time (Sec)

19. Test 1: Section vs. Velocity Time (Sec)

20. Test 2: Load Capabilities • Transportation of different-size materials • All materials had to be delivered in as short a time as possible • Max weight vs. reduced performance • Adjusted suspension based on necessary travel

21. Test 2: Weight vs. Time Time (Sec)

22. Test 3: Incline Capabilities • 2 of the 3 roads involved inclines • Must remain stable while climbing • Materials need to be transported safely across the roads • Used data to determine road of best fit for each object carried

23. Test 3: Angle vs. Time Time (Sec)

24. Test 4: Battery Life • Battery power runs all car components • Motor, receiver, 5 servos • Had to sustain operations for at least 15 min. (challenge time limit) • Found approx. life lost for each charge/discharge cycle • Optimal recharge time: 8 hrs.

25. Test 4: Battery Life vs. Recharge Time

26. Test 5: Ease of Use • Replacements in case of emergency • Team members with some experience • Used a random test group with varying RC experience • Subjects navigated a small course using our RC car

27. Test 5: Subject vs. Traverse Time Time (Sec)

28. Final Solution • Stampede car base, modified Plexiglas lid with actuating containment arm • Fulfilled all size and weight requirements at “resting position” with arms down • Etched Volvo Const. logo for aesthetics & weight reduction

29. How it Works

30. Nationals Results and Summary • 2nd in Road Rumble Challenge • “Good Neighbor” award for teamwork with our competing team (from Canada!) • 3rd in H2OH Yeah! Game show • Met many industry professionals and the President of Volvo Const. Equipment

31. Nationals Video

32. Lessons Learned Applied tech and math • Acceleration and velocity equations • Incline problems dealing with normal force and force of friction General • Pick a solution and go with it • Managed time produces great results • Never rule out the underdogs
