Micro-Grid Wind Energy System, Aaron Steinkraus, Brian Huntziker, Cesar Hurtado
Mechanical Engineering
With the completion of a 3.5kW wind turbine located on Esculea Ranch, the power generated from the turbine was dissipated through electric resistance heaters. ABC Wind was given the task to design, build, and implement a system what will efficiently use the turbine’s harnessed power. After interviewing with the Beef Operations Manager of Escuela Ranch, it was decided to use the turbine’s power to supply supplementary water to anywhere on the ranch where and when needed by grazing cattle. The purpose of this project was to research, design, build and implement a system that would harness the generated power and …

Formula Sae Turbocharger Engine Development, Eric Griess, Kevin Mccutcheon, Matthew Roberts, William Chan
Mechanical Engineering
This project, Formula SAE Turbocharger System Development, was sponsored by the Cal Poly, San Luis Obispo Formula SAE team. The team proposed this project in order to have a powerful yet lightweight engine so they can be extremely competitive at their competition. The baseline output of the single cylinder 450cc engine (2006 Yamaha WR450F) was 46 horsepower and 27 ft-lb of torque. The goal of this project was to increase the output of that engine to 60 horsepower and 35 ft-lb through the use of a turbocharger.

Formula Hybrid Drivetrain Design, Zachary (Zak) Mcfarland, Alex Pruitt, William Domhart
Mechanical Engineering
The Formula Hybrid senior project group was tasked with designing and building a drivetrain system for the Cal Poly Society of Automotive Engineers (SAE) Formula Hybrid (FHSAE) team. FHSAE gave customer requirements for performance and geometry for the drivetrain and the FHSAE rulebook has guidelines regarding safety requirements. The team chose to compete in the electric category of the 2012 FHSAE competition. After getting feedback from previous car performance and researching different powertrain options, the senior project team arrived at three conceptual ideas. Using a quality function deployment method, the senior project team chose the concept where two motors independently …

Amputations are a common occurrence in soldiers returning home who have suffered the effects of IED and munitions explosions. For upper limb amputees, trans-radial amputations are the most common. Traditional hook devices do not offer an adequate level of normalcy for users, prompting the use of myoelectric devices. While current myoelectric devices do offer a more natural experience, they come with a host of other problems that makes their adoption by service personnel not desirable or not permitted by the VA. PolyGrasp Reach seeks to reduce weight and cost and improve performance. This addresses several of the issues with devices …

Robotic Fingerspelling Hand For Deaf-Blind Communication, Brian Fang, Colby Dixon, Trevor Wong
Mechanical Engineering
Robotic fingerspelling hand for the deaf-blind. The hand forms the shapes of the American Manual Alphabet with 11 servos. The project was sponsored by The Smith-Kettlewell Eye Reaserch Institute.

California Olive Ranch Hedger, Tyler Enos, Seth Abbott, David Gamba
Mechanical Engineering
The purpose of this project is to evaluate the problems of the current KCI (Kingsburg Cultivator Incorporated) olive tree hedger in use at California Olive Ranch (COR) in Artois, CA, and then correct these problems which should yield a better performing, more efficient, and reliable machine. These problems include: the hydraulic oil temperature getting too high, the saw blades not having enough horsepower, and poor cutting performance due to operator error as well as terrain variations.

Sole Power: Pedal Phone Charger Final Report, Nicole Hensley, Anthony Ruh, Krista Schmidt, Joseph Garcia
Mechanical Engineering
The device design was conceived to meet the energy needs of rural populations in India. These communities have cell phones but lack access to reliable grid power, especially during monsoon season. The charger is designed to be affordable, durable, and easily repairable for each owner family. It uses off-the-shelf components and is intended to be replicated by backyard manufacturing startups in developing countries.
Its purpose is to efficiently transfer human foot motion via a treadle, four-bar-linkage, and sprocket-chain step-up to drive a rotor & stator generator from a common gas scooter. The single-phase alternating current from the generator is passed …
Pedaling And Braking Forces And Their Effect On Suspension Performance, Kathleen Kramer, Nik Goodell, Cesar Giron
Pedaling And Braking Forces And Their Effect On Suspension Performance, Kathleen Kramer, Nik Goodell, Cesar Giron
Mechanical Engineering
The goal of this project is to produce a quantifiable relationship between pedaling and braking forces and suspension behavior. The test results will serve as a benchmark, against which other suspension designs can be compared in an objective, numerical manner. This report details the work completed towards determining this relationship and is primarily focused on design development of the data acquisition system and analysis of braking forces, pedaling forces and suspension response. A 2011 Specialized Stumpjumper FSR Expert Evo was used as the development platform. The system will be used to measure various rear suspension designs for comparison.
