Rube Goldberg machine

  1. Feb 14, 2010 #1
    Hey everybody. I am starting this seemingly impossible and hard project of making a rube goldberg machine. Can anyone give me helpful tips and ideas on how to start it? and perhaps provide examples?

    Please provide the context and some background. We are not in the habit of doing your school project work for you here.

    This is my first time to make a rube-goldberg machine and am having trouble in coming up with ideas and ways to perform tasks like:
    -a motor powered shaft that moves a mass for 10sec (I was thinking of like those baggage centers in the airport, but have no clue on how to do it)
    -actvitating a pneumatic/hydraulics in an enclosed system (which i clearly have no clue how to do and this is probably the hardest of my tasks)
    If yu could give me simple tips on how to make a rube-goldberg machine (like how to make pulleys, and how to make use of electrical wires and tubes)
    I know this sounds like alot of rambling, I have all these ideas in my head but have no clue on how to do them, but I would really appreciate your help.
    This is my very first goldberg machine and my teacher isn't really helping me make this very much. I want to do good on it and actually understand how to make one.

    How can you be given an assignment that you have "no clue" how to do? Could I please have your professor's e-mail address and name so that I can complain about his teaching skills?

    Classic Rube Goldberg mechanisms perform very mundane tasks using excessively complicated methods. Your first step is to decide what end-result you need to accomplish. For example, squeezing toothpaste onto a toothbrush, or watering a plant.
    Ever seen a record player?
    Pneumatics = gas (usually air); Hydraulics = liquid (usually oil).
    Pneumatics are vastly easier to implement on a small scale.
    Pulleys, gears, belts, motors and such things are available inexpensively from many surplus vendors. Most cities have at least one electronics/industrial surplus store. Of course, there are plenty of online sources, for example:
    http://www.allelectronics.com/
    http://www.goldmine-elec.com/
    http://www.herbach.com/
    http://www.surpluscenter.com/
    Just Google http://www.google.com/search?q="basic+electricity"" are a whole 'nother beast. If you don't know basic electricity, don't even think about tubes.
    Write out your ideas in outline form. I find it is easier to keep track of what I want to do.
    (I use my Palm PDA, keeping it sync'd with my work and home PCs, so my idea/project outlines are always handy, and up to date.)
    If your teacher isn't helping, consult a different teacher.

    Pantaz: Thank you so much for your helpful reply. I now have an idea of what I'm doing and should do.

    Remember that it isn't a real Goldberg device unless it involves a parrot, a teakettle, a piece of toast, or a window blind (preferably all 4). :wink:
