Universal Tread For Power Wheelchairs, Daniel Ceja Gonzalez, Ryan Scarcella, Aaron Rocha, Brian Song

Mechanical Engineering

This project was centered around developing a fully independently driven powered wheelchair attachment that would allow users to traverse non-wheelchair accessible terrain. The initial goal was to create a full-scale model that would allow our user to use and test as a prototype to get over curbs and some light dirt off-roading. However, as the project progressed and limitations of time and money came up, this project was rescoped to a quarter-scale proof of concept model. The goal of this new project was to create a prototype that would carry a scaled-down load and traverse a scaled-down curb. This was …

Composite Pegboard, Asa J. Cusick, Luis Corrales, Joelle Hylton, Wyatt Pauley

Mechanical Engineering

Many of those with mobility limitations who are told they will need a wheelchair for the rest of their lives can actually begin to stand and walk again given the proper tools and support. The current design for a wheelchair seeking to support this process is overly complex, heavy, and exhibits some features that could potentially pose a serious health hazard to those using it. The scope of this project is to aid in the design of an adaptable composite wheelchair frame that can be both lightweight and strong, while still allowing for physical diversity of potential users. Through research …

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, …

Adaptive Exercise Equipment, Jake Ryan Walejko, Spencer Goodman, Kalina Burns, Journey Martinson

The task is to design adapted exercise equipment for the non-profit organization, Achievement House. The objective of this Final Design Review is to document the final design, manufacturing plan, design verification plan, and project management plan. In addition, this document includes previously presented information on the project background, objectives, and concept design. The background and objective sections document various forms of customer research and include the project goals developed by the athletes and fitness instructors of …

Service Dog Ramp, Matthew Lundgren, Ariel Tolentino, Dallas Rocha, Adam Mayeda

Mechanical Engineering

This project involves designing a device to help a service dog easily get into and out of a truck. It details the design and manufacturing process. The project was interrupted due to the COVID-19 pandemic, so detailed instructions are provided for whoever takes on the project in the future.

Katie's Jogger, Megan Guillermo, Erin Wint, Abdullah Sulaiman, Kathryn Mangiaracina

Mechanical Engineering

Edward Robinson is an avid runner who would like to take his daughter on runs. His daughter, Katie, is 100% wheelchair bound and currently does not fit in any commercial joggers on the market. The project team was expected to design, build, and test a custom working prototype of a jogger that the sponsor can use to take his daughter on runs. This entire project was performed over a span of three quarters.

Curb Navigation, Cole A. Tudor, Kaitlyn R. Adams, Robbie Huerta

Mechanical Engineering

The Curb Navigation senior project, proposed by the QL+ organization, was presented to find a solution to an issue a former veteran, Velette, is having. Velette has a difficult time maneuvering curbs when out doing day-to-day errands and activities. The goal of this project is to develop a solution that will give Velette the ability to traverse curbs without the assistance of others or the need to do a wheelie that can lead to an injury. The team has found that adapting and optimizing an anti-tipper design may be the best way to solve the proposed challenge. The team decided …

Beach Wheelchair Attachment, Abbey Jo Scholle, Jackson Dallas Wiley, Jackson Cole

Mechanical Engineering

This document includes the problem that is under scrutiny, the background research towards finding a solution, the objectives, scope of the project, the planned overall design process, the preliminary design we have produced and analyzed, the critical design we have manufactured, the testing and results, and the final assessment of the produced design. The problem is lack of easy access and movement for wheelchair users on the beach. Other solutions and designs have been logged under background research. With this information, the scope of work was designed to meet all the needs specified and describe how the specifications will be …

Wheelchair Tire Change, Vincent Aguilar, Martin Perez-Guzman, Spencer J. Solano

Mechanical Engineering

This project consists of a rear wheel wheelchair lift to be designed and created by a Cal Poly senior project team. This project was created for injured veteran Ms. Landeen who has the trouble of tracking mud into her house because of dirty wheelchair tires. The project was presented by the non-profit organization The Quality of Life Plus (QL+) Program. Much like when you remove your shoes coming into your home, Ms. Landeen needs a way to exchange her outdoor wheels for her clean indoor wheels.

The expected outcome of this project is a fully functioning device that will safely …

Inclusive Lectern, Trent Canales, Sean Day, Dylan Sigley, Stephen Sippel

Mechanical Engineering

A lectern is an essential piece of equipment for almost all speeches and presentations. They come in many forms and range in degree of professionalism depending on the occasion. Lecterns not only hold a presenter’s notes, a microphone, or other presentation aids, they provide a structure for a presenter that can bolster their confidence during a presentation. As such, it is important that all presenters have a lectern available to them. Unfortunately this is not always the case due to lectern accessibility limitations. This problem inspired the Cal Poly Disability Resource Center to request a lectern that satisfies the Least …

School Van Access In Nepal, Edgar Corona, Humberto Maldonado, Josh Schiesl

Mechanical Engineering

A need has been identified by a school in Nepal intended for children with Cerebral Palsy, called Sathi Sansar, to develop a more effective solution to loading and unloading students onto the school’s Toyota HiAce van. Currently, a combination of the driver, parents and teachers manually help the students on and off the van. However, this task has proven to be both laborious and time consuming for all parties involved. A solution to this problem needs to be designed and one is currently being developed by a team of engineering students from California Polytechnic State University-San Luis Obispo and Katmandu …

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.

Foam Wars Ii, Sumant Advani, Sivadas Menon, Casey Pieplow

Mechanical Engineering

The team producing Foam Wars II consists of three Mechanical Engineering students and five Kinesiology students (three the first two quarters and two the last quarter) at California Polytechnic State University, San Luis Obispo. The project is the second iteration of Foam Wars as a senior project at Cal Poly, sponsored by Dr. Kevin Taylor under the National Science Foundation grant. Persons with disabilities often feel limited when it comes to recreational activities and Foam Wars would provide them with an outlet to interact and engage themselves in a group setting. The game consists of various wheelchair attachments that would …
