Our Team Leader's favorite quote:
What is the first rule of engineering?Why we think we should win:
Each year we get better and better and this year is the best.Suggestion for next year's challenge:
Putt a golf ball into the hole.
Rube enjoys all kinds of music - from classical to country to disco. Our machine takes a look at Rube's favorites.
Our Step List
1 Coin is inserted into spiralling slot.
2 Coin completes circuit on the motor on ticket box, turning on conveyer belt which pushes out ticket
3 Falling ticket pulls out syringe, releasing conductor and releasing the wire which falls into water completing the circuit thus starting the music.
4 Conductor rolls down inclined plane and pushes lever
5 Lever turns on motor that pulls string
6 String pulls out wood pieces that turn on violinists
7 Last violinist's back knocks over neck of cello
8 Cello neck hits string, triggering rat trap
9 Rat trap pulls trigger of dart gun
10 Dart hits "gong," knocking over lever
11 Lever hits ball, which rolls down inclined plane
12 Ball falls into bucket, releasing elevator
13 Elevator pushes against piano
14 Piano hits lever which turns page
15 Page turns, completing circuit
16 Motor pulls notes into wood on a swivel, releasing pulley system
17 At the top of the pulley, guy knocks off ball
18 Ball pulls string, turning off notes and releasing record
19 Record screw down and falls into record player, pulling string connected to saxophone
20 Saxophone turns, releasing cart
21 Cart rolls into exit box, allowing Cello to open
22 Cello opens, and hits a lever connected to two switches
23 Turns on the motor which rotates the machine by 1/3 to reveal the Country Music. At the same time, a dowel is removed from the comic foreground of a maestro, to reveal a Cowboy.
24 When the machine turns by 1/3 one lever hits the Comic foreground to turn off the rotation of the machine. A second lever hits the comic foreground to start the rotation of the ukelele on the Country Music.
25 Spinning Guitar strikes CD on weighted fulcrum (and as machine completes its 1/3 turn the motor is switched off and the rotation stops).
26 CD hits string which pulls out peg that was restricting the lever
27 Lever tilts on its axis and a barrel fall down the tube.
28 barrel hits one end of a lever at the bottom of the tube, which causes the other end of the lever to lift up
29 mechanism on truck allows the truck to rise, acting as an inclined plane for a barrel to roll down
30 the barrel rolls off the truck and lands on one end of another lever. The other end of the lever lifts to push another barrel off the shelf
31 as the barrel falls off the shelf, a pulley system works to lift a mousetrap
32 Mousetrap pulls string knocking over the 1st barstool
33 as the first barstool falls, it pulls out a pin that holds down a barrel, releasing the barrel to lift up
34 the barrel lifting up causes horseshoes to fall down in a pulley system
35 as the horseshoes fall, they lands on a lever which rises to release another barrel
36 as the second barrel rises, it sets off a mousetrap below which releases the second barstool to fall
37 the second barstool falls on a snake lever which holds Woody in place to prevent the saloon door from opening
38 when Woody is released by the snake lever, his platform rotates on a fulcrum and allows the saloon door to open
39 when the first saloon door swings open, it pulls out a pin that holds the second door closed, opening the door
40 as the second saloon door opens, it causes a bunch of horseshoes to fall, putting down the deer head held in place on the wall
41 as the deer head spins downward, the antlers hit a lever that hold a CD case in place, releasing the CD case and allowing it to flip downwards
42 as the CD case flips downwards, it releases a CD to roll down a series of four ramps along the wall
43 the CD knocks a hinge that holds a "banjo player wanted" sign in place. A mini guitar is held up by the sign, so the guitar is released when the CD knocks the sign
44 as the first mini guitar falls, it hits a lever that holds the second mini guitar up, caused the mini guitar to fall
45 as the second mini guitar falls, it turns on two motors: The first turns on the second 1/3 rotation of the machine and the second turns on the first dancer of Disco. In addition, as it begins to turn, it knocks over the comic forground of the cowboy to reveal the Disco Dancer.
46 Spinning Dancer releases CD which is propelled upward via a string on a pulley connected to a weight. (And as the machine completes its second 1/3 turn, the motor is switched off and the rotation stops).
47 CD strikes front of "TV set" lever releasing the CD "yo-yo" which slowly falls downward
48 CD Strikes switch which simultaneously turns on Disco Light and spinner that will release Slinky (note, the circuit for the light is completed by wire submerged in salt water)
49 Spinner tilts shelf which acts as a lever which releases slinky
50 Slinky proceeds down alternating shelves until it hits a switch
51 Switch turns on Turntable which spins and hits another switch
52 Switch turns on the second dancer. Second dancer turns on switch.
53 Switch turns on second turntable which spins and hits another switch
54 Switch turns on the third dancer. Third dancer turns on fourth dancer.
55 Fourth dancer knocks over a roller skate which rotates around its wheel and axle in order to pulls string attached to a dowel
56 Dowel releases second roller skate from its lever which pulls string attached to drink dispenser.
57 Drink dispenser dispenses liquid until liquid level is below the level of the wires and Turns Off The Disco Light!

Our Machine Verbal Presentation. This is your team’s chance to shine and be creative! We want to hear the story your machine tells, and understand how the steps represent the theme and key elements of your narrative. The Machine Introduction should not be a step-by-step explanation of how the steps work. This is where your personality, humor, and team spirit engages the audience and gets them excited to see your machine.
