Geneva Mechanism

Overview

To design the Geneva Mechanism, I first looked at schematic sheets to understand the different parts of the mechanism I would need to create. After that, I attempted to make it on my own, but it went poorly since I did not have the necessary clearance.

Tutorial

After realizing that I did not know what I was doing, I decided to follow a tutorial on how to make a Geneva mechanism and followed this tutorial. I did not just want to follow these instructions directly, and my goal became to make it a 10-drive slot cam. After following the tutorial and making it 10 drive slots, this is what it looked like in Fusion360:

Simulating

One of the key parts of the project is that I needed to simulate a working relationship between my different components in Fusion360. I first heard that as we needed to animate the relationship, and this mistake cost me a day and a half of work. Additionally, my original design, despite my best effort, was unable to work. This caused me to have to find another tutorial and get that one to work.

One of the big differences I found between the two designs was that the simulations lacked any clearance for the parts. I do not know why this is a necessary factor, and it may not be, but in the tutorial, I found no clearance was given for the components. The most notable thing about making simulations, I found, was that I needed ground components so that the components I wanted to spin would be able to.

Eventually, I did get the simulation to work, and here's the video of that working:
