Animations[edit]

These are all my animations I've done for Wikipedia!

Straight Line Mechanisms[edit]

Approximate Straight Line Linkages[edit]

To see the original article they're used for, see the Gallery for Straight line mechanism.
You can also directly visit each linkage's individual page if available in each diagram's caption.

Perfect Straight Line Linkages[edit]

To see the original article they're used for, see the Gallery for Straight line mechanism.
You can also directly visit each linkage's individual page if available in each diagram's caption.

Four-bar Linkages[edit]

Standardization / Style[edit]

My animations are done entirely using GeoGegbra as of now. If you spot an error, let me know!

Ruleset[edit]

  1. All Diagrams are made in GeoGebra.
    • Links are set to size 13 (maximum width)
    • Joints are set to size 5. Colored black by default. Point type is the colored dot with a black outline.
    • Ground Joints are set to size 6. Colored black by default. Point type is the cross.
  2. Size for diagrams are a 646 pixels by 646 pixels square by default. (There isn't actually a reason as to why this is the case. I could've chosen 500x500 or some other value, but 646 for some odd reason stuck with me.)
    • Sides at a minimum have to be at least 646 pixels.
    • If a mechanism is too wide or tall for a square, change it to a 1.5:1 or 1:1.5 ratio (969 x 646 px or 646 x 969 px).
    • I have yet to come across an animation that requires even wider or taller ratios, but if required, just go by multiples of 323, starting from 646.
  3. Parts of the same color have the same dimensions. This is the color pallete priorities I'm using in RGB:
    • Cyan - 26, 187, 178 - Usually the power source.
    • Pink - 247, 181, 236 - Indicates an output link of significance (e.g. A bar travelling rectilinearly)*
    • Orange - 233, 102, 46 - Indicates an output if two unique straight lines are formed from a single mechanism.
    • Magenta - 255, 0, 140
      • Indicates an output if two unique straight lines are formed from a single mechanism.
      • Highlights the pin for a slot.
    • Amethyst - 167, 31, 255 - Indicates a slide and slider.
    • Gold - 255, 193, 82 - Larger than green links.**
    • Lime - 124, 191, 114 - Smaller than yellow links.**
    • Indigo - 103, 104, 180 - If really necessary, which it rarely should be.
    • Sky Blue - 164, 195, 239 - If really necessary, which it rarely should be.
    • Red - 189, 52, 48 - Not used yet, but can be.
    • Brown - 109, 81, 72 - Not used yet, but can be.
    • Blue - 54, 57, 218 - Not used yet, but can be (hang on how many unique links does your linkage have?!)
  4. Output is animated in a sinusoidal motion.***
  5. Diagrams are either a PNG or GIF file.
    • Framerate is 20 FPS.
    • Recorded using ScreenToGif. May find a better program one day but this is very sufficient, especially as it can allow for specified recording dimensions and at whatever framerate as you wish, along with other useful things.
  6. Links that are planes rather than lines should be shaded in. (Refer to the Quadruplanar Inversor diagrams for an example.)

* This is still a bit inconsistent. I'll have to create a proper standard for this.
** There are exceptions for this, such as GIFs that are directly related to each other, such as the Parallel 4-bar Linkage GIFs.
*** The only exception to this is the Sylvester-Kempe Inversor 3 (cyan crank rotates regularly) and Sarrus linkage (the yellow links go WAY too fast if the output travelled sinusoidally, so I made it follow the function which runs a lot more smoothly.)

It's a pretty long list, and I'm curious to hear about thoughts on this as well. I'm open to suggestions! I'm also, of course, willing to make new linkages upon request from people, being this is quite a lot to follow, haha.

Tasks Pending[edit]

Animation Wishlist[edit]

  • Roberts table constructed from cognates of the Roberts linkage
  • Slider cognates
  • Tangent converter

Known Issues[edit]

  • Chebyshev Linkage.gif - Anchors are not equal in size.
  • Chebyshev Lambda Linkage.gif - Anchors are not equal in size.
  • Chebyshev Table Linkage.gif - Anchors are not equal in size.
  • Roberts Linkage.gif - Triangle link should be shaded in.
  • Bricard Inversor.gif - Anchors are the wrong texture. (appears as • rather than ×)
  • Quadruplanar Inversor 4.gif' - Contraparallelogram's opacity is not set correctly.
  • Quadruplanar Inversor Derivation Alt.gif' - Rectilinear bar should be dashed.
