Flame Propagation Test for Space Bound Materials Jarred Druzynski, David Fredriksson, Brandon Huffman, Alexander Poirier, Joseph Templeton

This testing rig performs NASA's Standard 6001B Test 1 which determines if different types of materials are safe for space travel based on their ability to self-extinguish when ignited. Two vacuum chambers stack on top of one another and house many other sub-assemblies required to meet the test requirements. The bottom chamber contains two air inlet assemblies to help blow the smoke and small particulates out. In order to get the additional data, the test rig is outfitted with the following data acquisition sensors: a load cell, a pressure sensor, a thermocouple, thermistors, a radiometer, and a camera.

Icarus RT - Organic Rankine Cycle (ORC) Power Generating System Jose Castellanos, Carlos Duran, Angelina Forzisi, Cristian Hernandez, Corina Lard, Christopher Oyuela

The goal of this project is to develop an Organic Rankine Cycle (ORC) that serves as a proof-of-concept for generating power from waste heat extracted and recovered from Icarus RT’s solar array.

Lithium Processing Chamber Jack Bowen, Mike Johansen, Ilze Sarma

The objective of this project is to design and to manufacture a lithium processing chamber.

 

M

Marker Band Sorter Jason Agtina, Roselynn Conrady, Theresa Escolano, Nathan Fosgett

An automated, machine vision sorter that sorts marker bands based on color, utilizing a Pixy2 Camera. This sorter is designed to be interchangeable with a Keyence XT-24 3D scanning camera, capable of measuring band length tolerance. In addition, this sorter will allow a bulk amount of marker bands to be automatically sorted into separate containers.

Moment Manipulating Arm Support System with Non-Circular Gears Patrick Fleckenstein, Naufal Hidayat, Freddy Rivas, Noah Stanley

The goal for this project was to create a variable moment system using non-circular gears that functioned the same as Levitate Technologies’ current design, which utilizes tension springs and pulleys to achieve a higher cycles till failure. The cables for the pulley system were the first to fail, and would not meet a satisfactory amount of cycles. The use of gears would eliminate the need for cables, increasing the lifetime of the product and reducing its size . Using Matlab, the group was able to design a set of non-circular gears the would operate from 0 to 162 degrees.

 

 

Multi-AUV Deploying System Gabriella Garcia, Analie Samawi, Garry Valdez, Remmy Wilkinson, Max Yant

NIWC’s Unmanned Maritime Vehicle (UMV) Lab is currently using Remotely Operated Vehicles (BlueROVs) to serve as low-cost Autonomous Underwater Vehicles (AUV). The BlueROVs are deployed by hand off a kayak or small boat alongside an Unmanned Surface Vehicle (USV) used to remotely communicate with the BlueROVs. The UMV Lab asked for a Multi-AUV Deploying system that will attach to the pontoons of the USV. This was accomplished by creating two identical systems that are activated by a single remote and are attached on opposite sides of the USV. Each system deploys a single BlueROV at a minimum distance of 20 meters.

NIWC Hydrokinetic Turbine Cameron Alegria, Andre Camunas, Evan Johnson, Ivette Silva, Tremaine Sorge

A vertical-axis hydrokinetic turbine capable of producing at least 1 volt from water flow speeds down to 0.3 m/s at an operational depth of 15 meters.

One-Handed Pill Bottle Opener  Daniel Campas, Claire Santos, Matt Schierman, George Sosa, Kyle Williams

The team was tasked to create a device that allows users with neuromuscular disorders and injuries such as amputation and hemiplegia, to independently manipulate push turn pill bottles. The device is portable, making it easy for clients to take their medications when traveling or while completing daily tasks. The design of this device is purely mechanical and functions without the use of any batteries.

 

 

Oscillating Load Mitigation Backpack Blake Goring, Fadi Essa, Grant Huggins, Keaton Mahaffey

To design a suspension system that would mediate the dynamic loads transferred to the wearer of a backpack while walking.

 

Otterbotics Self-Driving Golf Ball Picker  Eric Gillhaus, Scott Halverson, Zach Hewitt, Liam Kerrigan, Mikey Swan

The project goal for our team is to create a mechanical system attached to an AGV to collect golf balls from a driving range. Our team paired with Otterbotics to add three subsystems to their self-driving vehicle. Our design allows for autonomous operation while collecting 1,000 golf balls in a single run. Once the bin is full, the AGV returns to the set point and distributes the balls evenly into external collecting bins.

PD FRED (Public Domain Floating Robot to Eliminate Debris) Calvin Dixon, Nick Feiner, Matt Kersman, Jason Waas

The objectives of this project are to design and build a production version of FRED (Floating Robot for Eliminating Debris) that can be feasibly built by ocean conservationists across the world to support Clear Blue Sea’s mission of cleansing the oceans of plastic solution. Our project is 10 foot pontoon robot that is able to be remote controlled from up to a half mile from the shore. The design consists of a conveyor belt system that dips into the ocean and brings surface level debris to a bin on the aft. All systems aboard are powered by batteries which are charged by two solar panels atop the vessel.

Robotic Segway Walker Victor Hernandez, Minh Hoang, Sam Kearns, Isaiah Oropeza

The goal for this project is to design a robotic walker that is in the format of a two-wheel Segway with internal self-balancing mechanism.

Simulation Software for Geothermal Power Plant Marwa Abduljabbar, Kris Gaard, Nathan Gibfried, Travis Ryan, Joe Stephens

Controlled Thermal Resources is working on optimizing a geothermal power plant to be built in the Salton Sea geothermal field. A simulation was developed to accurately model the piping system of a similar plant. This allowed us to visualize and test the effectiveness of different piping solutions. A comparison between the current system with cement lined carbon steel, and a system with titanium clad steel was explored.

 

Solar Panel Heat Extractor Alora Aguilar & Christian Ramirez

Our team was tasked by Icarus RT, Inc. to fabricate novel heat extractors for use in extracting waste heat from the surface of photovoltaic (PV) panels to be converted back into usable energy. Throughout their daily operation, the surface temperature of PV panels can vary greatly, often into temperature ranges that cause the PV panels to be less efficient. These extractors would allow the PV panel surface temperature to remain in the highest efficiency temperature range, while the heat from the working fluid can be converted into energy for use on-demand

Tracking System - Pyrheliometer Tiare Corral, Bryan Ikeda, Yadira Velez

To build a low-cost pyrheliometer and its tracking system

UAV Porta-Launcher Fernando Casas, Austin Clements, Patrick Greene, Joseph Mazzeo, Ayendra Subasinghe

The UAV Porta-Launcher was built to launch an Opterra 2-meter drone for NAVWAR. It can be launched remotely, collapsed and transported with ease, launched at adjustable speeds between 10mph and 50mph, launched at adjustable angles between 10 and 30 degrees, and weighs just over 50 pounds.

 

Underwater Autonomous Unrolling Mat Yousef Alsahli, Parker Bailey, Abhishek Pandya, Mark Sutton

Our team was tasked with designing a system to unroll a mat on the ocean floor with a total area of 100m2, for the purpose of deploying a microbial fuel cell that generates electricity from bacteria designed by our sponsors. In order to do this our team designed a pneumatic system that unrolls the mat using hoses that are filled with pressurized air.
