El Capitán: Cal Poly Rose Float Digital Drive System, Gregory Raffi Baghdikian

Computer Engineering

In today’s world of smartphones, self-driving cars, and internet-connected coffee makers, it seems as if computers are contained in everything around us. These “embedded systems” have become critical components of our lives, improving everything about the things they control, from cost, to speed, to simplicity. One area that embedded systems has hardly gained a foothold is in the world of floatbuilding. Most of the floats in the Tournament of Roses Parade, including the one built jointly by Cal Poly San Luis Obispo and Cal Poly Pomona, are technologically very simple, using mostly analog components and rudimentary discrete digital logic to …

Universal Weight Machine, Oscar Andrade, Bibiana Koch, Robert Molloy, Haley Rentfro, Emily Woods

Mechanical Engineering

The purpose of this project is to design and build an inexpensive, universally accessible multi-station exercise machine for the physical and mental well-being of athletes of the Special Olympics and Pathpoint Life Education & Advancement Program. The machine has three sides tiered to higher resistance: the first station offers a minimal resistance aerobic exercise focused on moving the arms with an ergometer, the second station provides numerous locations to latch on resistance bands that will build strength in the athlete’s arms and chest, and the final station has a donated weight machine that offers lat pulldowns and flys with maximum …

Metals Am Design For Manufacturing, Maren Cosens, Ben Wong, Kevin Hale

Mechanical Engineering

We are looking to improve upon the current post processing techniques for metal additive manufacturing (AM). This project, sponsored by Lawrence Livermore National Laboratory (LLNL), will investigate ways to improve the design of stainless steel 316 parts made by AM, and how these designs will help with post processing techniques. We hope that the findings regarding stainless steel will apply to to improve the AM and post processing handshake in general. In particular, the project will focus on including different features in different basic part design shapes to aid in fixturing and post-processing of the part made by AM. This …

Automated Bearing Press, David Baker, David Brock, Engelbert Diec

Mechanical Engineering

Our group was presented with a challenge to design an automated machine to replace Micro-Vu’s current manual pressing operation. We moved, planned, and scheduled our tasks for the three quarters we will be working on this project by using a Gantt chart. In designing the machine, we generated concepts and used analysis and prototyping to select the most promising ones. Our final design uses a pneumatic press to press the parts, and it includes magazines to hold the parts before pressing, pneumatic actuators to move the parts to and from the pressing location, and a lever to separate the defective …

Design And Testing Of A Top Mask Projection Ceramic Stereolithography System For Ceramic Part Manufacturing, Dylan Robert De Caussin

Master's Theses

Ceramic manufacturing is an expensive process with long lead times between

the initial design and final manufactured part. This limits the use of ceramic as a viable material unless there is a large project budget or high production volume associated with the part. Ceramic stereolithography is an alternative to producing low cost parts through the mixing of a photo curable resin and ceramic particles. This is an additive manufacturing process in which each layer is built upon the previous to produce a green body that can be sintered for a fully dense ceramic part.

This thesis introduces a new approach …
