Final Design Review Report: The Underdogs, Parker Johnson, Jack Montgomery, Katherine Thomas
Final Design Review Report: The Underdogs, Parker Johnson, Jack Montgomery, Katherine Thomas
Mechanical Engineering
Aspen is a three-legged dog with mobility issues from Berkeley, California. She was hit by a car and her rear left leg was amputated at the hip. Robin Swanson, Aspen's owner, and her friend, Audrey Beil, are the sponsors for this project. Jack Montgomery, Katherine Thomas, and Parker Johnson, “The Underdogs”, are tasked with helping Aspen regain some of her mobility and the ability to go on walks. Research was done into the problem by talking with the sponsors and looking into existing products, designs, and patents. This document, the Final Design Review Report, outlines the background information, problem specification, …

2 Degree Of Freedom Robotic Leg, Oded Tzori, Henry Terrell, Adan Martinez
Mechanical Engineering
Professor Xing, an assistant professor at Cal Poly, proposed the 2 DOF Robotic Leg project for this quarter’s senior project class. The project is to build a robotic leg attached at the hip to a stand, which will be used as a teaching tool and eventually help develop Cal Poly’s very own robotic quadruped. Since this project has multiple uses after its completion, there are multiple customers that it must perform well for: the Cal Poly Mechanical Engineering (ME) Department, the ME Lab instructors, and the students. The Scope of Work (Sections 2 & 3) is composed of 2 main …

Design Of Structural Stand For High-Precision Optics Microscopy, Sara T. Novell
Master's Theses
Lawrence Livermore National Lab (LLNL) is home to the National Ignition Facility (NIF), the world’s largest and most energetic laser. Each of the 192 beamlines contains dozens of large optics, which require offline damage inspection using large, raster-scanning microscopes. The primary microscope used to measure and characterize the optical damage sites has a precision level of 1 µm. Mounted in a class 100 clean room with a raised tile floor, the microscope is supported by a steel stand that structurally connects the microscope to the concrete ground. Due to ambient vibrations experienced in the system, the microscope is only able …

Spring Loaded Camming Device, Jared S. Christner, Kaitlin O. Deherrera, Ryan W. Edwards, John S. Hickey
Mechanical Engineering
Spring loaded camming devices or “cams” are used in traditional rock climbing as a means of active fall protection. Climbers place cams in cracks and fissures in the rock wall. The cam’s lobes press against the walls, locking it in place, anchoring the climber in case of a fall. Currently, there is a lack of large cams on the market. Only two small companies produce cams that are usable in cracks 6.5 inches wide and larger, however their designs are either too heavy and/or lack features to be comfortable. We are a group of mechanical engineering students at Cal Poly …
Cal Poly Supermileage Dynamometer, Jacob Randall, Nate Deffenbaugh, Kyle Milgram
Cal Poly Supermileage Dynamometer, Jacob Randall, Nate Deffenbaugh, Kyle Milgram
Mechanical Engineering
Our senior project involves designing a chassis dynamometer capable of simulating variable loads for the Cal Poly Supermileage Vehicle (SMV) team. The chassis dynamometer we are developing uses an alternator to develop additional resistance that the vehicle will have to overcome while testing. To implement a control system for the variable load, we use an Arduino Nano paired with multiple sensors and drivers. This control system allows the user to select different levels of resistance that correlate with different road grades. We designed a custom Printed Circuit Board (PCB) that will contain all the electrical components needed for the control …
