Apply A BAND-AID®
Online Family Division - All Ages
What we're studying:
All members of the team are studying Mechanical Engineering at Wilkes University. All members are seniors. Our Team Leader's favorite quote:
"The great scholar forgets about fame, the worthy scholar works for it, and the unworthy scholar steals it."
"Try to leave this world a little better than you found it and, when your turn comes to die, you can die happy in feeling that at any rate you have not wasted your time but have done your best" - Lord Robert Baden-Powell
"Nothing happens, unless first, a dream" - Carl SandburgWhy we think we should win:
We believe that we should win for several reasons. First and foremost, our machine has many advanced machine design components that are used in different ways than they are normally used, showing our out of the box thinking. In addition, we not only built the machine on a small budget, we also made a complete 3D model of each step and an overall assembly in addition to a 2D drawing package of all steps. The team has also completed countless calculations in order for our machine to properly work. Finally, we made our machine so that it was somewhat whimsical, yet was professional enough to count for our senior design capstone project. Suggestion for next year's challenge:
Open a soda bottle. Favorite Rube Goldberg video:
This machine is being utilized as our senior design capstone project. It is designed to both be whimsical and re-purpose as many items/household items as possible, in typical Rube Goldberg fashion. In addition to utilizing as many engineering principles and advanced machine design components such as cams, gears, power screws, etc. and still apply a band aid.
Our Step List
1. Push button sends electrical power to motor.
2. Motor spins sprocket.
3. Sprocket system moves chain in clockwise direction.
4. Chain moves bolt downward.
5. Bolt pushes down platform.
6. Mass falls off of platform and pulls up other mass.
7. Second mass pulls upward and releases heart-shaped pendulum.
8. Pendulum swings and impacts rod.
9. Rod rotates nut counter-clockwise around bolt.
10. Rod and bolt impact tennis ball.
11. Tennis ball rolls down ramp.
12. Tennis ball impacts with cam.
13. Cam raises and lowers follower
14. Mass falls off of follower and raises second mass off of see-saw.
15. See-saw falls and hits switch.
16. Switch sends electrical power to power screw.
17. Power screw rotates clockwise and releases spring from end.
18. Spring falls and impacts bolt.
19. Bolt impacts ball bearing which rolls through tube.
20. Ball bearing hits bolt into mass.
21. Mass falls off top and down to bottom of machine.
22. Mass pulls stop plate out of way of spring.
23. Spring pushes toy truck forward.
24. Truck impacts bar attached to gear train.
25. Bar turns on light switch.
26. Switch sends electrical signal to desk fan.
27. Desk fan spins and pushes Rain-gutter Regatta boat forward.
28. Boat pushes plate into mass.
29. Mass falls causing scissors to close and cut string.
30. String releases first ball of Newton’s Cradle.
31. Newton’s Cradle final ball impacts with marble on track.
32. Marble pushes bolt with 6 nuts into bucket.
33. Bucket pulls up stop block and releases Pinwood Derby car.
34. Pinwood Derby car rolls down ramp and impacts with rod attached to gear train.
35. Gear train rotates rod with rubber mallet attached.
36. Mallet rotates and pushes down one side of hydraulic press made of syringes.
37. Other end of hydraulic press pushes up plate and allows mass to fall.
38. Mass moving causes chain and sprocket system to rotate.
39. Mass hits plate attached to snail cam and causes it to rotate.
40. Cam rotates and pushes white marble along platform.
41. Marble bounces off of guide rail and falls into funnel.
42. Marble rotates around and falls through funnel.
43. Marble hits spring-hammer release.
44. Spring-hammer hits cannon release.
45. Cannon pushes mass into middle of machine.
46. Mass lifts stopping mass out of way of marble.
47. Marble rolls down three ramps and impacts with light switch.
48. Switch sends electrical power to power screw.
49. Power screw rotates counter-clockwise and lowers bar.
50. Bar rotates “plank-held bar”.
51. Bar turns on light switch.
52. Light switch sends electrical power to motor.
53. Motor spins cam.
54. Cam lifts follower.
55. Follower pushes up one end of hydraulic press.
56. Second end of press pushes up PVC tube cut in half.
57. Band-Aid applied to arm.
