    Machine Mayhem 2022

    The Task

    Each section will design and build a "machine" - this means anything that includes mechanism, actuation, automation and application, so:

    Mechanism: mechanical degrees-of-freedom (DOF)

    Actuation: computer-controllable motion of the above DOFs

    Automation: software-coordinated computer-control of the above, and i.e. sequences therein

    Application: pipelines from desired (designed) outcomes (shapes generated, patterns drawn, parts picked-and-placed etc), to actual outcomes (real stuff!)

    Layering / Interfacing

    messy

    interface

    layerish


    Examples / Ideas

    The machines you design and build don't need to be complicated - try to de-risk ideas early, and do stuff that "works right away" rather than complex projects that require hundreds of details to come together all at once in order to work. This can be fun; have fun.

    Label Maker

    Wire Cutter

    Music Machines

    String / Floating Machines

    Architecture-Scale / Space Transforming

    Claw Machine

    Robot Chainsaw Machine

    Robot Basketball Hoop


    Strategies

    • use interfaces / modularity to split work up,
    • keep your parts, and your tools, organized
    • have a group chat ! invite your TAs !

    Hardware

    Composable Axis

    Composable Rotary

    Extrusions, Brackets, etc

    • structure, etc

    Machine Week Kit Contents

    Here's the list... with the note that we have extras of most line items, so groups need to get a handle on what they will need and let us know where to restock early early !

    Electronics / Software

    based on urumbu, which are also available to use, we are supplying circuits and examples for modular-thing of which there are many circuits
