In this project, we were assigned to use a gear, a cam, and a crank. To integrate these mechanisms creatively, we built a humorous narrative around IShowSpeed's China Tour and his "complicated" interactions with Zhangwei Da and Yiming Tian. Each mechanical part was assigned a unique role to enhance both storytelling and functionality. The gear powers Tian's monocycle as he drips water onto Speed's head, prompting Speed to duck—an action achieved through the crank mechanism. Meanwhile, Zhangwei takes on the role of a boxer, using alternating left and right punches (driven by the cam) to comically hit Speed’s backside. The result is a fun and dynamic demonstration that brings the characters and mechanisms to life.
