Apply A BAND-AID®
Online Division II - Ages 14 - 18 (High School)
What we're studying:
Synergy and problem solving. Lots and lots of problem solving.Our Team Leader's favorite quote:
OMG! IT WORKED?!!Why we think we should win:
Despite our modest and humble beginnings in a small town in Ontario, Canada, we have envisioned, designed, tested and refined a brilliant machine that can be used for the greater good of humanity. This special healing machine epitomizes the quality health care for which Canada is known and celebrated.Suggestion for next year's challenge:
We think that plugging in a phone charger would be a great task for next year.
Favorite Rube Goldberg video:
The BandAidinator 4000, is Glendale High School's entry in the 2017 Rube Goldberg Machine Online Contest. This brilliant machine gently and creatively applies a Band-Aid to an injured person with a 100% success rate. The machine represents the beautiful synergy and problem-solving skills of team members who are fairly new to the Rube Goldberg scene at Glendale. Special thanks to Ian, Cheryl and Zachary Barton.
Our Step List
1. An injured person, requiring a Band-Aid, presses the button of the BandAidinator 4000, turning on the machine.
2. The button, via an Arduino, activates a solenoid dropping a metal rod.
3. The metal rod pushes a weight off of the end of the ramp.
4. The falling weight causes a pair of scissors to close, cutting a string.
5. The cut string moves through a system of pulleys releasing a weight which pivots a see-saw.
6. The pivoting see-saw causes a ball bearing to roll down the see-saw and through a tube into a cup.
7. The cup falls tightening a string connecting the cup and a plastic rod.
8. The plastic rod releases a pendulum which hits a wooden train.
9. The wooden train rolls down the track and activates a lever.
10. The lever pulls a string, releasing a Newton's Cradle.
11. The Newton's Cradle hits a marble.
12. The marble rolls along a track and hits a lever. The top of the lever pushes another marble that rolls down a ramp. At the bottom of the ramp, this marble hits another lever that pushes a third marble which rolls down the top ramp.
13. The marble then rolls through a marble run and activates a mousetrap.
14. The mousetrap triggers a switch.
15. The switch engages an oscillating fan assembly.
16. The fan assembly knocks a weight off of the side of the machine.
17. The weight drops pulling out a piece of wood from beneath the hammer.
18. The hammer falls triggering the screw grabber to open.
19. The screw grabber releases a marble which moves down a tube and then a zigzag ramp.
20. At the bottom of the zigzag ramp, the marble triggers a run of dominoes made of Band-Aid boxes.
21. The Band-Aid boxes set off a mousetrap.
22. The activated mousetrap pulls a string that removes a magnet from a wooden train.
23. The train rolls down the ramp and hits a lever.
24. The lever causes a ball to roll down a ramp.
25. At the end of the ramp, the ball drops and impacts a switch.
26. The switch turns on a drill.
27. A threaded rod in the drill causes a paint roller to move forward.
28. The paint roller gently applies the Band-Aid to the injured person.
