What we're studying:
We are studying a wide variety of topics, some unintentionally. Primarily we are studying energy transfer, principles of engineering and problem solving for when steps don't always flow as cohesively as they should. We are unintentionally learning about teamwork, and how to move forward and solve conflict within the design and the group.Our Team Leader's favorite quote:
"Education is the most powerful weapon which you can use to change the world."
-Nelson MandelaWhy we think we should win:
We think we should win because our machine is well structured and has complex components that elicit reactions other than stereotypical steps like dominoes. We have opted for more difficult reactions like completing a circuit with a vinegar and baking soda solution in order to raise a ramp and so forth. We have intertwined creativity and engineering, telling a story while completing a task.Suggestion for next year's challenge:
Make a sailboat sail, drop an anchor, put on a pair of glasses, paint a mannequin's nails, button a dress shirt, kick a soccer ball, sharpen a pencil, tie a shoelace
Our machine is a hotel continental breakfast bar functional with 3 shelves where nothing ever seems to say place and cabinets that always seem to cause a ruckus no matter what. Though a series of coils, pulleys, strings, electronics, ramps, gears and more our machine tells the story of little Joshy and his clumsy adventure at a hotel's continental breakfast.
Our Step List
1. Group 1: To start the machine little joshy accidentally pulls a campbell's soup can.
2. Unbeknownst to him, this creates a ramp of sorts causing a ball bearing to fall.
3. This in turn hits a different campbells can causing them to roll.
4. This hits a salt and pepper shaker which falls into a basket.
5. The added weight in the basket causes the string to tighten and pull a meat tenderizer.
6. Group 2: The meat tenderizer hits the box of rice and causes it to fall down.
7. When it falls it hits a limit switch.
8. The limit switch starts and opens a trap door.
9. When the trap door opens the orange conveniently placed there falls through the door causing a spatula to begin wobbling
10. The wobbling of the spatula knocks over the some baking soda.
11. This creates a vinegar baking soda solution which completes the circuit.
12. By completing the circuit an inclined plane raises.
13. The raise in the inclined plane triggers a ball to roll down it hitting a mouse trap.
14. The mouse trap snaps triggering the opening of the door to the mouse house.
15. By the door being opened the mouse scurries away until it hits a golf ball.
16. The golf ball rolls a bit after being hit until it falls through a hole and down a ramp and into a basket.
17. Group 3 This causes the basket to fall and hit the fridge.
18. When it hits the fridge it pulls a release causing ball bearings to fall into a cup.
19. The weight causes the cup to lower and in turn open the freezer door.
20. The opening of the freezer door causes bottles of orange juice to topple over.
21. When the orange juice falls over it hits a button. The button triggers the first cabinet door to open.
22. When the cabinet door opens it causes the cereal boxes to topple over like dominos.
23. When the last cereal box falls down it hits a button which simultaneously brings up the current cabinets door and releases the second cabinet door.
24. Group 4 The door falling causes the string attached to a nail gets pulled in turn pulling a nail through a wooden post.
25. This releases a piece that moves down a coil.
26. Attached to the piece moving down the coil is a string that is attached to the trigger of a mouse trap. Once the coil piece gets down the coil far enough it will release the trap.
27. When the trap releases it throws a tide pod down the ramp.
28. Attached to the mouse is another string also attached to a block The string pushes the block into the open pad, closing the corner.
29. The tide pod rolls down the ramp and slides into a glove attached to a pulley. The pulley activates and releases a ball.
30. The ball rolls down a path. At the end of the path is a circuit that gets closed by the metal ball.
31. The motor activates now that the motor is closed. The motor pulls a string attached to paper towels.
32. The rolls unravels. Attached to a paper towel deeper in the roll is a string connected to the next groups first step.
33. Group 5 The paper string roll pulls the lever which makes a ball bearing fall down down the ramp.
34. The ball bearing runs into the pulley in turn pulling out the support of the fruit basket.
35. The ball bearing falls through the coffee maker and into a cup.
36. This cup falls on onto a lever triggering the container to open by way of string.
37. The allows the ball bearing to continue and run into a mouse trap.
38. The mousetrap pulls the release on the toaster and the release for the cereal.
39. The toaster triggers a mousetrap.
40. The mousetrap pulls the support thereby pouring the milk. .
