Rube Goldberg was an American cartoonist of the early 20th century. He drew cartoons that exemplified the most inefficient, complex, means of completing a task. Here is a web page with an example cartoon nad more information, http://www.rubegoldberg.com/gallery_01.php . (The British have their version of “Rube Goldberg” style artist. His name was Heath Robinson.)
Complete this activity before building your Rube Goldberg Machine. It will be due weeks before the contest. Check the main contest page for the date.
Early Project Requirement
Before the contest, you will build and turn in an electrical circuit in a Rube Goldberg fashion. You are to build a battery powered device, “bpd,” that is remotely controlled. This means you will have a wire carry the electricity to a motor or other electrical power device.
Most any battery-powered device, (“bpd,”) is easy to control via remote. Your remote controlled device must meet the following criteria.
The final Rube Goldberg Machine –building rules.
For your final Rube Goldberg Machine, you will build a device whose goal is to put toothpaste on a toothbrush. Your machine must be secured to a base of foam core or wood no larger than 20” x 30”. Your device must have at least 8 sequentially working steps.
A working step is defined as a triggering that causes an action. See the web site www.mrwaynesclass.com/ProjectRube/steps to see an animation describing how a “step” is defined.
You will be provided with paper columns and beams that can be used to build a base from. You are not required to use our paper columns and beams -but you must use something.
Hint: Many people like to use dominos in their device. But they are time intensive to set up. Here is a method for resetting dominos quickly. Tape down one side of each domino to act as a hinge.
If you have looked at the exmple machines linked at the top of the page, you will see that each machine uses gravit as ts power source. You can do hte samething, For students who have entered this contest as part of their project grade, you will receive card stock patterns that you can use to build a study, elevated, platform (as shown below.)
