Sean‘s pick this week is Fidget Spinner (Simscape Multibody) by Pavel Roslovets.

It wasn’t even a couple months ago that I first heard of a fidget spinner in this Time Magazine article. Within a week, all of the sudden they were everywhere. Well, now they’re in MATLAB too!

Pavel has used the physical modeling tool Simscape Multibody to build a dynamic model of a fidget spinner. He imports the geometry from a CAD model and then wires it up to the appropriate blocks. The entire model is just a few blocks. There’s also a video of how to build up the model voiced over in Russian.

Let’s see it in action:

Since many of you probably don’t have the required toolboxes to see the model. I’ve gone ahead and exported it to a web view using Simulink Report Generator. Here’s a link to it: Fidget Spinner Model Web View.
