    Machine Week 2023

    everything's connected but nothing's working ! 

    Your (Group) Task

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

    Mechanism: mechanical degrees-of-freedom (DOF)

    Stuff shuld move around.

    Actuation: computer-controllable motion of the above DOFs

    The motion should be computer controlled.

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

    The motion should result in some desired outcome... maybe make something, draw something, change something, assemble something, sort something, cast a spell, etc.

    We can also think more broadly about "tools" - what does it mean to build a computer-controlled system that acts like a tool, interacting with the world but being mediated by some designer's intent... it's a foamcore world.


    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

    Examples from this Kit

    MechE Components

    Framing Gussets

    ! IMG of each, link to cad. Maybe a set of them "deployed" in a chassis.

    Belt Axis

    ! IMG of it, link to cad and BOM, or a readme-each?

    Leadscrew Axis

    ! IMG of it, link to cad.

    A Rotary Axis

    Using the design pattern explained here.

    The Blot


    MechE (examples)

    • clank
    • corexy (of dave)
    • beehive axes
    • ... add some more

    Examples

    • the blot (or some plotter: motion control, servo, stepper)
    • xylophone (motion control, low-fet, stepper)
    • drum stik (accel, low-fet)

    Stable Circuits

    • stepper
    • servo
    • low-fet
    • BNO085
