Single Arm Recumbent Bicycle, Alexander Borsotti, Ryan Westermann, Sean Liston

Mechanical Engineering

The goal of this report is to outline and cover the scope of work for the Single Arm Recumbent Bicycle Senior Project. The report will give an introduction of the problem, a background of the existing research or products relating to our project, the objectives of our project, our project management plan, our final design, manufacturing, testing, our project management, and final recommendations for improving the final design. The team is being supported by the Quality of Life Program, a non-profit organization that works to improve the lives of those injured in duty while serving our nation.

Team Joseph's Bike Trailer, Keely Thompson, Curtis Wathne, Ryan Meinhardt

Mechanical Engineering

This final design report shows the results of this senior project’s design process of creating a custom bike trailer for Team Joseph. As done in the Scope of Work, Preliminary Design report, and Critical Design report, current products, relevant technologies, and American Society for Testing and Materials (ASTM) standards are fully researched and benchmarked to aid in the design selection process. Customer requirements are looked at and developed into engineering specifications. A detailed design was created for CDR to show to Team Joseph, and manufacturing and testing plans were laid out. This final design report adds the final design revisions …

Final Design Report: Allergen Mixing Assistant (Ama) Micro-Refrigeration Redesigning, Mitchell Parks, Minwoo (Michael) Suh

Mechanical Engineering

Abstract

Allergen Mixing Assistant (AMA) by Xtract Solutions is a device designed to more “effectively refrigerate, organize, and mix allergenic extracts”. Although Xtract Solutions intended the product to be fully automated, the company has decided against its automation and declared its current design as a minimum viable product whose components are too expensive, difficult to source and complex. Therefore, Cal Poly AMA design team - Mitchell Parks and Minwoo Suh - has decided to replace these expensive components with much more economical alternatives as shown below:

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 …

Low-Cost Strider For Guatemala, Nicole Catherine Cooper, Gonzalo Hernandez, Jared W. Tower

Mechanical Engineering

The purpose of this project was to create a strider, a type of standing rehabilitation device, for children in developing countries who have trouble walking and supporting their full body weight. The project was initially brought to us by Cal Poly professor Brian Self, who had visited a clinic in San Marcos and determined that there were children there who had difficulties with walking and were a need for a rehabilitation device. The team discussed the problem with Dr. Self, Matt Robinson (a local San Luis Obispo prosthetist), and Cal Poly physics professor Pete Schwartz, all of whom had visited …

Beach Wheelchair Project, Rory Aronson, Joshua Marcum, Samuel Coyne, Alex Hayes, Alexa Colburn, Max Hessel, Benedikt Strauss, Marvin Rimmele, Marco Pietsch

Mechanical Engineering

The Beach Wheelchair, Sandcrawler, is a machine intended to help give people with disabilities the full beach experience. The non-profit organization Bridge II Sports sponsored this project, and tasked us with developing the design and fabricating a prototype. This chair has several features including a linkage mechanism that raises and lowers a chair relative to an external frame, hand crank drive with Gates Carbondrive belt and sprockets, buoyant Wheeleez balloon tires, and much more.

Wiihopp, Jeff Christian, Ben Hoselton, Derek Simon

Mechanical Engineering

Childhood obesity is becoming a growing problem in the United States. According to the CDC, childhood obesity has more than tripled in the past 30 years [7]. It can lead to health problems previously reserved for adults, such as diabetes, high blood pressure, and high cholesterol. For the team WiiHopp project, we plan to turn a JumpSport mini-trampoline into a controller for the Nintendo Wii console. The hope is to help turn the problem of video games and the laziness surrounding them into an active solution to combat the problem of childhood obesity.

Our goal is to produce an add-on …

Low-Cost Prosthetic Leg For The Vida Nueva Prosthesis Clinic, Sarah M. Baker, Justin G. Lekos, Jen Van Donk, Kevin Yamauchi

Mechanical Engineering

The Piernas de Vida team partnered with the Vida Nueva Clinic of Prostheses and Orthoses in Choluteca, Honduras to design, plan, and implement a prosthetic foot that could be manufactured entirely by the technicians at the clinic in order to reduce their costs and ultimately allow them to serve more patients each year. Currently, the clinic uses a prefabricated prosthetic lower limb provided by the International Committee of the Red Cross (ICRC) which can be adapted to both transDfemoral and transDtibial patients. The team has successfully developed a foot, currently called the Layer Foot, which can be used by the …
