The process for creating the prototype was very simple. We repurposed the links for the slider-crank mechanism created earlier in the semester by changing their lengths. We then laser cut the links and fashioned them into the crank-rocker. Then, the vertical path cam and temporary cat wand were cut out. The cam was attached to a base with the crank-rocker and the cat wand was attached with a hinge to the output link.

It may also be possible to allow for 3 degrees of freedom by implementing a four-bar slider mechanism that will push the toy in and out. While this will not be a part of the prototype, it could be possible to add it afterwards.
