Adjustable Medical Assistance Bed, Michelle Callson, Andrew Chen, Deborah Flores, Devin Meadows Jun 2019

Adjustable Medical Assistance Bed, Michelle Callson, Andrew Chen, Deborah Flores, Devin Meadows

Mechanical Engineering Senior Theses

The objective of this project is to design and manufacture a bed that provides increased safety and convenience to patients needing physical assistance and their caregivers, specifically catering to special needs patients. The bed is designed to have variable height between 0” and 30” from the bottom of the mattress to the ground, allowing the patient to get into bed with minimal physical assistance from the caregiver. The design process for this product was organized in three subsystems: lifting mechanism, escape prevention, and frame. The lifting mechanism is designed to accommodate the bed’s variable height, as well as support ...


Pedal 4 Purification, Cory Yamagata, Coleton Rodd, Jonathan Keyes, Matthew Lograsso Jun 2019

Pedal 4 Purification, Cory Yamagata, Coleton Rodd, Jonathan Keyes, Matthew Lograsso

Mechanical Engineering Senior Theses

The lack of access to clean drinking water remains one of the largest issues still facing humanity. The Pedal 4 Purification is a product that addresses this need by utilizing pre-existing bicycle infrastructure and local freshwater sources to allow people to purify their own drinking water on a daily basis. Attachable to any standard bicycle, the Pedal 4 Purification product consists of pump, purification, cart and adjustable kickstand subsystems that allow the operator to pump, purify and transport 40L of potable water. Pedaling at the reasonable rate of 60 rpm will provide the optimal flow rate of 1.54L/min ...


Design Of An Urban Garden Aquaponics System, Riley Albright-Borden, James Wang, Sydney Thompson Jun 2019

Design Of An Urban Garden Aquaponics System, Riley Albright-Borden, James Wang, Sydney Thompson

Interdisciplinary Design Senior Theses

The project objective is to create a durable, off-the-grid, large-scale aquaponics system consisting of over 90 sq. ft of growing space, a 650-gallon fishpond, and four types of sensors to transmit water quality data to the internet for remote water quality monitoring. The end goal of the project is to supplement produce grown in the garden to further increase fresh, nutritional options available in meals cooked and distributed by Loaves and Fishes Family Kitchen to combat food insecurity in San Jose. This report presents the need for a system, details the various subsystems, and the rationale for the designs. It ...


Power-Assist Wheelchair Attachment, Catherine Van Blommestein, Ryan Boyce, Rosemary Cole, Matthew Marks Jun 2019

Power-Assist Wheelchair Attachment, Catherine Van Blommestein, Ryan Boyce, Rosemary Cole, Matthew Marks

Mechanical Engineering Senior Theses

This senior design project sought to combine the best characteristics of manual and power wheelchairs by creating a battery-powered attachment to propel a manual wheelchair. The primary customer needs were determined to be affordability, portability, and travel on uneven surfaces. After the initial prototype, using a hub motor proved unsuccessful, so a second design was developed that consisted of a gear reduction motor and drive wheel connected to the back of the wheelchair by a trailing arm that could be easily attached/detached from the frame. The prototype of the second design succeeded in meeting most of the project goals ...


Automatic Romaine Heart Harvester, Jonathan Borst, Chuck Culberson, Andrew Torrance Jun 2019

Automatic Romaine Heart Harvester, Jonathan Borst, Chuck Culberson, Andrew Torrance

Mechanical Engineering Senior Theses

The Romaine Robotics Senior Design Team developed a romaine lettuce heart trimming system in partnership with a Salinas farm to address a growing labor shortage in the agricultural industry that is resulting in crops rotting in the field before they could be harvested. An automated trimmer can alleviate the most time consuming step in the cut-trim-bag harvesting process, increasing the yields of robotic cutters or the speed of existing laborer teams. Leveraging the Partner Farm’s existing trimmer architecture, which consists of a laborer loading lettuce into sprungloaded grippers that are rotated through vision and cutting systems by an indexer ...


Environment Chamber For Shape-Memory Alloy Testing, Luis Acevedo, Joseph Bodo, Nicholas Fernandes Jun 2019

Environment Chamber For Shape-Memory Alloy Testing, Luis Acevedo, Joseph Bodo, Nicholas Fernandes

Mechanical Engineering Senior Theses

The purpose of this project is to design, test, and build a temperature-controlled environment chamber to enable tensile testing of shape memory alloy (SMA) wire specimens at a temperatures ranging from 80-200°C. The most important design specifications were a maximum exterior wall temperature of 40°C and a maximum temperature variation along the specimen length of ±5°C, with end users' ease- of-use considered. Hand calculations and iterative finite element analysis (FEA) simulations in SolidWorks were used to verify design choices before proceeding with sourcing parts and materials, and assembly. Real-world implementation of the system showed a heat-up time ...


The Seedling Sanctuary: Automated Cold Frame For Gardner Elementary, Fiona Bell, Christopher Carpio, Alex Kosaka Jun 2019

The Seedling Sanctuary: Automated Cold Frame For Gardner Elementary, Fiona Bell, Christopher Carpio, Alex Kosaka

Mechanical Engineering Senior Theses

The purpose of this report is to provide the details of the Seedling Sanctuary, a mechanical engineering senior design project. The project in question is an automated cold frame designed specifically for Gardner Academy, a local elementary school in San Jose. A cold frame is a miniature greenhouse that opens like a chest and is made from clear plastic. Automated ventilation and watering systems create a microclimate within this greenhouse structure to create the ideal growing conditions for seeds. The main purposes of the cold frame are to lengthen the growing season, be maintenance free, and enhance garden education. From ...


Swarm-Based Techniques For Adaptive Navigation Primitives, Nathan Metzger May 2019

Swarm-Based Techniques For Adaptive Navigation Primitives, Nathan Metzger

Mechanical Engineering Master's Theses

Adaptive Navigation (AN) has, in the past, been successfully accomplished by using mobile multi-robot systems (MMS) in highly structured formations known as clusters. Such multi-robot adaptive navigation (MAN) allows for real-time reaction to sensor readings and navigation to a goal location not known a priori. This thesis successfully reproduces MAN cluster techniques via swarm control techniques, a less computationally expensive but less formalized control technique for MMS, which achieves robot control through a combination of primitive robot behaviors. While powerful for large numbers of robots, swarm robotics often relies on “emergent” swarm behaviors resulting from robot-level behaviors, rather than top-down ...


Human-Centered Electric Prosthetic (Help) Hand, Jamie Ferris, Shiyin Lim, Michael Mehta, Evan Misuraca Apr 2019

Human-Centered Electric Prosthetic (Help) Hand, Jamie Ferris, Shiyin Lim, Michael Mehta, Evan Misuraca

Interdisciplinary Design Senior Theses

Through a partnership with Indian non-profit Bhagwan Mahaveer Viklang Sahayata Samiti, we designed a functional, robust, and and low cost electrically powered prosthetic hand that communicates with unilateral, transradial, urban Indian amputees through a biointerface. The device uses compliant tendon actuation, a small linear servo, and a wearable garment outfitted with flex sensors to produce a device that, once placed inside a prosthetic glove, is anthropomorphic in both look and feel. The prosthesis was developed such that future groups can design for manufacturing and distribution in India.
