A Rube Goldberg Machine is a multi step complicated machine created to completed a simple task.
Our Rube Goldberg was built over the course of 5 weeks with 1 planning, 3 building, and 1 presenting. Our Theme is "Around The World," we featured the United States, Europe, and Asia. The objective was to raise the flag of the world. The board is created with mostly wood, its painted blue with scattered clouds. The photos in the background are cut and pasted. In order to make the wood pop out of the board we painted it like a road as if the marble was a car.
For the first week of planning we came up with 3 tied ideas. Technology, Netflix, and Around The World. In the end we chose around the world as it had the most capability. Traveling is something most of us enjoy and can connect with. The schematic here------------> is the original design. Using the power of gravity through the ramps to move the ball. This design was the bare minimum of what was needed so we changed a few things.
From the first design to the last our build got longer and more finalized. For example, ways to catch the changing ball and less steep ramps for a longer Rube Goldberg. Our Rube Goldberg also featured two electrical circuits.
Electrical circuits:
L.E.D.s: All four of the lights where connected in parallel with a tinfoil switch to activate it. On ramp 4 the ground and power where disconnected until the ball connected the circuit.
Motor: The motor was controlled by a button at the bottom, controlled by the pulley. The ball would fall into one side and the pulley would push the button on the other.
Build log:
Day 1: Planning Rube Goldberg
Day 2: Measuring and drawing out plan on board.
Day 3: Start building, attached track 1, 2, and Lumbard Street.
Day 4: Attached the London Eye and track 3.
Day 5: Attached step 1 (lever) and brainstormed ideas for screw.
Day 6: Attached screw and brainstormed pulley ideas.
Day 7: Attached the pulley. First test run. started painting background.
Day 8: Finished painting background. Printed background photos. Plan New York lights and motor.
Day 9: Cut and pasted land marks. Attached LEDs and motor.
Day 10: Wired LEDs and motor. Finalized pulley. Worked out any bugs through testing.
Day 11: Finalized build. Practiced presentation.
