This project was done in collaboration with two classmates for the class Robot Design Mechanism. We were tasked with creating a mechanism that would convert circular motion (crank) into a linear motion (slider). After deciding on a design I made a 3D model of the parts and put them into an assembly to check for feasibility. Once we knew that the parts we needed would look like we decided which rapid prototyping method would be best for each part. We ended up using 4 different methods, 3D printing the slider, laser cutting the links, manual vertical milling the main body, and metal lathing the steel rods. I was in charge of using the lathe, doing the laser cutting, and some of the milling operations. This project was a great example of using the best prototyping method for the right job and also helped us learn about choosing the best material for the job.
