Movement Components

Rube Goldberg Machine Components The Building Blocks of Complexity

In a Rube Goldberg machine, movement components are the backbone of the complex series of events. These components use different types of movement to transfer energy from one object to another, creating a chain reaction that ultimately leads to the desired outcome. A well-designed movement component can make or break the success of a Rube Goldberg machine.
There are several types of movement components that are commonly used in Rube Goldberg machines, including rotational, linear, and oscillating movements.

Rotational Movement

Rotational movement is one of the most commonly used types of movement in Rube Goldberg machines. This type of movement involves the use of a wheel or axis to change the direction of a moving object. Rotational movement can be used to transfer energy from a rolling ball to a series of levers, which then trigger a chain reaction.
For example, the classic Rube Goldberg machine features a rolling ball that triggers a series of levers, which then drop a hammer onto a series of dominos, creating a cascading effect.

A simple example is to use a rolling ball to trigger a lever that opens a small gate.
A more complex example is to use a rotating wheel to transfer energy to a series of pulleys, which then lift a heavy object.
Another example is to use a rotational movement to power a small motor that then activates a series of mechanisms.
