2017 Thermal Energy Storage Device for Solar Cooking
PROJECT SUMMARY
TECHNICAL APPROACH
Convex Solar has been tasked by GTech Precision with the design of a solar thermal energy storage device to be used for cooking. In many parts of the world where electricity and cooking appliances are not accessible, wood and fossil fuels (coal) are burned to provide the heat needed to prepare meals. This presents a health hazard as the gases produced in burning these materials are toxic, particularly when burned indoors. According to WHO, as many as 4 million people are killed from indoor air pollution every year. Solar cookers are an alternative to burning fuels, but they have the limitation of only being useful when there is sunshine. To make use of solar energy for cooking at times when there is no sunlight, Convex Solar will design a Thermal Energy Storage (TES) device that will absorb and insulate solar energy. The design is in it’s early stages, so the target now is to boil water 1 liter of water within 20 minutes with the deviceA Fresnel lens will be used to concentrate solar radiation. The materials for used for storage and insulation are still being considered. Currently, Therminol is being considered for used as a heat storage material, though it is usually used for heat transfer.
There are three components to the system Convex Solar has proposed. The first is the energy collection and storage device. This device has three parts: An insulated pot where the TES material will be placed, the TES material itself, and a collector plate that absorbs solar radiation. Affixed to the plate are fins to improve heat transfer. Currently, Therminol is being considered as TES material. The second component of the system is the Fresnel lens that will be used to collect the energy. The third component is the frame that will be used to track the sun and ensure the concentrated solar energy is properly targeted on the collector

2018 Sheet Music Page Turner
PROJECT SUMMARY
TECHNICAL APPROACH
Musicians often turn the sheets themselves or have someone turn it for them. It is not a particularly easy thing to do, especially when both hands are being utilized simultaneously. Performers who participate in an orchestra or concert often spend weeks or even months preparing for these events. However, even something as simple as one sheet sticking to another is enough to ruin a good performance.
The main motivation for this project therefore is to provide an easier way for musicians to access the next sheet of notes while still playing the instrument. The objective of this device is to enable them to play the instrument without affecting the quality of their performance. Although many have attempted an approach to this concept, either as a commercial product or as an experimentation, it appears that these products still need improvement and are not yet suitable to be employed by musicians.
Performance Innovations will take advantage of available products and inspect their mechanism and scheme. From this, we will either enhance previous models or develop our own unique equipment. We hope to develop a competitive product that is compatible with most standard musical instruments and stands, while minimizing the cost without sacrificing its functionality.
Performance Innovations have completed market research and performed a designselection process. We have narrowed down our ideas and decided that we are going topursue two design paths. The first includes designing a rotational “binder spine”mechanism that will either be a single axis movement or a two axis movement. Wethen completed several solid models using SolidWorks. Then, with these models, we3D printed a rough prototype of the single axis movement helix design, as well as aconnectors for the pages in the scroll design. The second course of action is revisingPagePlease!’s existing product, aiming to cultivate a more efficient mechanism withone motor, reducing noise by installing the motor inside the housing, and timing belt-pulleys system that would drive the entire mechanism at the same pace.

2017 Personal Robotic Assistance Arm
PROJECT SUMMARY
TECHNICAL APPROACH
Kinematic Solutions was asked to come up with an alternative solution for prostheticarm. After researching existing products, it was clear that a lightweight, inexpensive,modular robotic arm would be a great alternative to existing products.
Current robotic arms only address a select amount of our goals. Light weight roboticarms are usually hobby bots and cannot take the day to day use. The robots that cantake the day to day use are usually extremely heavy and expensive. Existing fullyrobotic arms usually require some surgical procedure to interface with the wearer.With the cost associated with amputation, our goal was to come up with a solutionthat would not pose as much as a financial burden on a person in need.
Kinematic Solutions set out to design and test a relatively light, inexpensive, modularrobotic arm. The team intends to show that a robotic prosthetic arm can be designedand constructed such that it can be mass produced at minimum cost. KinematicSolutions wants to show that our careful design and material selection can make anaffordable arm for those in need of personal assistance devices.
Kinematic Solutions set out to research current robotic solutions for amputations andfound the best concepts that could aid in the design of a lightweight, inexpensive,modular arm. Throughout the research stage self imposed limits were set for theoperating conditions of the arm; weight, loading, movement speed, and cost. Usingcommercially available composite material and stepper motors with a carefullydesigned structure, the weight and cost of the device can be driven down. Thesoftware will be integrated with another project being overseen by the ComputerScience Engineering department. The end goal for the arm is to work with thesoftware to carry out commands based on input from the image recognition software.

2015 3D Printed Aircraft Fuselage
PROJECT SUMMARY
TECHNICAL APPROACH
Aerospac3D appreciates the opportunity to research on behalf of Stratasysin order to implement effective standards for Fused Deposition Modeling (FDM) for aerospace structures. We are looking forward to working closely with Stratasys to provide the most effective fuselage deliverable.
Past models have been delayed in reaching testing stages due to the hefty weight of materials, failing joints, and lack of documented printing standards for FDM. What Stratasys needed was a clear solution to these problems. Aerospac3D is ready to address those needs. Employing an organic modeling approach to the DG-1 design, our team can create a wing that is stronger, lighter, and effectively adapted to the FDM environment.
Through cutting edge modeling, optimization, slicing software, and our dedicated team, we believe that Aerospac3D’s professional methods, practices, and tested ability to deliver results are precisely what Stratasysis looking for.
Using data imported from openVSP, Solidworks will be used to create a surface model of the aircraft. This will include both the outer surface and internal supporting structure. Aircraft design is a highly iterative process. As one area of design is refined, so then must another area be refined. Structure created in the Solidworks surface model will be heavily influenced by the optimization data from ALTAIR Hyperworks, a FEM tool which will be used to optimize the internal support structure.
The geometry of internal support structure will also be a function of test 3D prints. These will be fuselage-shaped sections reinforced with various types of support. This support most closely resembles a stringer or frame in a full size aircraft. Due to the challenges associated with 3D printing, the team aims to combine these two structures into a single unitized structure. This optimizes the strength of the airframe, while reducing weight.

2018 Optimization for the Internal Topology and Sizing for Thin-Walled Aircraft Structures
PROJECT SUMMARY
TECHNICAL APPROACH
DS WingSquad will work with an existing aircraft design and test it'sviability as a thin-walled aircraft structure to be manufactured by fuseddeposition modeling. In doing so, a design guideline will be written tocommunicate and document the steps taken to design, analyze,optimize, and manufacture the aircraft structure.
The team will work with Aerospac3D (who is working on the fuselagedesign) to generate CAD models for the different components of theaircraft structure. A topology and sizing optimization will be run inorder to distribute the load path through the structure in such a waythat stresses are minimized where necessary. The overall design willneed to take into consideration the constraints and challenges thatarise from the fused deposition modeling.
We gratefully acknowledge the sponsorship of Stratasys Ltd. along withthe helpful guidance of Dr. Taylor.
DS WingSquad intends to show that fused deposition modeling is avalid process for the manufacturing of thin-walled aircraft structures. Todo this the team will determine external loads experienced in flight anduse Altair's finite element software programs to obtain a designoptimized for the determined load sets. First the team will run atopology optimization in order to determine an optimal stiffenerpattern, followed by a sizing optimization to determine the optimalthicknesses of the internal stiffeners. Design work using Solidworks willbe an integral aspect of the project helping produce models to beexported for optimization. Due to the constraints of fused depositionmodeling, joints will need to be employed where structure componentsare longer than the maximum printing length. The Insight slicingsoftware will be used to slice CAD models, and generate and customizetoolpaths. Once the plane is manufactured, the team will undergo atesting process to analyze the results and validate the hypothesis aboutmaximum loading.

2017 TestFixtureforFlammabilityofMaterialsTesting
PROJECT SUMMARY
TECHNICAL APPROACH
AeroBurn was tasked to develop an airflow system to be attached to atest sample during a fire penetration test. The purpose of the airflowtunnel is to simulate in‐flight conditions and a fire breaking out in theengine compartment of a plane. We were asked to design the systemto fit within an existing test room, and the system had to be able toreport flow rate, temperature, differential pressure, and to be able tochange flow rate during a flame test.
Currently there are no off‐the‐shelf systems which fulfill this task. Twoof the client’s competitors perform this test, but they apparentlycustom‐built a testing system in‐house. The FAA has guidelines and asuggested system design which we used as the basis for our design.
AeroBurn engineers therefore set out to design a system which wouldmeet the FAA guidelines, as well as fit within the constraints of theclient’s existing facility.
AeroBurn engineers first calculated the flow rate in the test sample holder box, basedon the velocity provided by the customer. We then investigated various pipe sizes,attempting to obtain the pressure differential required by the FAA guidelines. Wedesigned a Venturi, but it was determined that it was too big and added too muchweight to the system. We then turned to the pitot tube (below right) for the flowmeasurement, temperature, and differential pressure reporting. We researchedvarious vibration controls to vibrate the system the during penetration test. We alsoresearched various fan options, using the air flow velocity and differential pressure asdetermining factors in fan size and blade type. A temperature analysis was done forvarious materials (below left), to make sure that the sample holder box would notdistort or break during the fire test.

2018 Lifelong Learning Machines
PROJECT SUMMARY
TECHNICAL APPROACH
ARLM Technology was tasked to develop a small-scale system which will showcase
machine learning in a dynamic environment. Over the past few years, those in the field
of robotics have begun to develop self-learning machines that aim to mimic human
capabilities. This evolution has led to a diversification in robotic applications.
ARLM Technology has set out to develop a model which will portray a city clean up
system with a robotic arm capable of sorting various objects and carts which can
autonomously drive to desired locations. This will be accomplished by using the AL5D
robotic arm working in conjunction with Hercules rovers to gather, sort, and return
assorted colored blocks. The blocks simulate different materials that would be sorted
in a recycling system.
The arm/rover system will use various sensors and cameras to locate and identify the
colored blocks while navigating and avoiding obstacles on the test bed.
We gratefully acknowledge the sponsorship of the University of Texas at Arlington
Research Institute (UTARI), and the guidance of Dr. Aditya Das and Dr. Hakki Sevil.
The first criterion considered was whether to build a robot arm from scratch or to buy a built one. ARLM Technology opted to purchase the robot arm hardware as building one from scratch would take a lot of time. We chose the Lynxmotion AL5D Robotic Arm Kit because of its simplicity and ease of use. The robotic arm’s workspace was increased by coupling the arm to a translating carriage. The linear rail system is actuated by a stepper motor and controller that is compatible with raspberry pi and Robotic Operating System (ROS).
The robotic arm is currently hardcoded to demonstrate the full range of motion of the system. The following step will be to apply inverse kinematics and an imaging system to target colored blocks for the robotic arm to grab, lift, and place in a new location.

2017 Autonomous Sun Tracking Solar Panel and Deployment System
PROJECT SUMMARY
TECHNICAL APPROACH
Apollo’s Wake Engineering has been tasked to research and design asolar powered generator that will autonomously deploy and activelytrack the sun.
Traditionally, mobile gas generators are used to power electronicswhile the power infrastructure is repaired after disasters. They are alsoused in rural areas that might not have access to electricity. In bothscenarios, fuel is an important resource and might not be available, soother means of electricity are needed.
The deployable solar tracker will be fitted with an active trackingsystem so it can be set up at any location and work automatically. Thesolar panel tracks the sun to charge the battery as efficiently aspossible.
Apollo’s Wake Engineering wants to be able to power a 30 Watt LED flood light throughthe night and be able to fully charge a battery through the day.Four light dependent sensors split into quadrants will be used to sense where the sunis in the sky. In order for the solar panel to move, a motor will be used to rotate thepanel while a linear actuator will be used to adjust the panel’s angle. Amicrocontroller will be used to measure the resistances across the sensors and thenadjust the solar panel to face directly towards the sun. A scissor lift will serve as thedeployment system and raise the solar panel into the air.

2018 Electric Skateboard
PROJECT SUMMARY
TECHNICAL APPROACH
RAD Engineering was tasked with developing and designing thepinnacle of electric skateboards that could provide an exhilaratingexperience for the rider not only on pavement but also on the roadleast traveled. Through market research and testing, a need was foundto provide a lightweight, powerful, off-road capable, electricskateboard at a reasonable price.
Currently used suspension designs on commercial electric skateboardsincludes board mounted axles (known as “trucks”), bearings, andbushings, allowing the skateboarder to turn by transferring theirweight on the standing platform (known as the “deck”). This systemworks on pavement, however, not for rough terrain. Since independentsuspension is a method currently employed on off-road vehicles tohandle adverse road conditions, RAD Engineering has decided tocombined these two ideas to create the pinnacle in off-road electricvehicle entertainment.
Representatives from RAD Engineering met with an independent electric skateboardcollector who allowed us to test out several commercially available electricskateboards currently on the market. From these experiences, it allowed us todetermine which parameters make an electric skateboard more enjoyable for the rider.Due to acceleration and top speed being critical to rider enjoyment and to becompetitive in the current market, RAD Engineering decided to set a top speed withrider of 30mph and an acceleration from 0-30mph in 8 seconds. Additionally,independent suspension was added to increase rider enjoyment, safety, and add towhere the skateboard can be ridden. Once the global goals were known, mathematicalmodels were developed to determine: required torque, deck material and method ofconstruction, and suspension design. Based upon modeling of the skateboard, a dual,rear-wheel driven brushless motor setup was selected to meet our goals. Once themotors were known, batteries and method of controls were determined. Currently acomplete Solidworks assembly of the board has been constructed along with FEManalysis performed in ANSYS for the critical components of the skateboard.

2018 A Handheld/Wearable Device for Force Feedback Stabilization
PROJECT SUMMARY
TECHNICAL APPROACH
The NAVIgaiter Engineering Group was tasked by The PettingerFoundation to develop a device that can be worn/carried and act as aforce feedback device to help improve gait and stability in elderly,disabled veterans, those with neurological conditions, and others.
Through multiple visits to nursing homes, Dr. Pettinger has observedthat due to a fall, or multiple falls, the elderly begin to deterioratequickly because of the complications that they may experienceafterward. This creates a distinct need for a device to assist the elderly,or others, to improve their gait and balance.
The NAVIgaiter Engineering Group’s intention is to design a device thatuses either reaction wheels, gyroscopic forces, or a moving linear massto provide a force feedback. The goal is to keep the devices weightunder 6 lbs, volume no larger than 0.5 ft3 and a force feedbackgeneration of 1.5 ft-lbs or greater.
The NAVIgaiter Engineering Group conducted research into reaction wheels,gyroscopes, and moving linear mass systems. A decision matrix was used tocompare the following categories for each concept: weight, size, cost,portability, usage time, feedback capabilities, life cycle, electronic controlcapability, and durability. Since a sliding linear mass only has control over oneaxis for feedback, it was eliminated, and the decision matrix pointed toreaction wheels for our first choice. Next, a house of quality was used todetermine which engineering characteristics were most important. Torque,volume and weight were determined to be the top three engineeringcharacteristics. Following the house of quality, a test was done to comparetorque output and the weight of the disk for reaction wheels and gyroscopes.Gyroscopes became the clear leader abovereaction wheel requiring much less weightto provide the same torque output. A
detailed design for the gyroscopes, internalcomponents, and their external housingunit have been created.

2017 Variable Displacement Engine
PROJECT SUMMARY
TECHNICAL APPROACH
GE-6 Challenge was tasked with the dynamic analysis and design of a lift mechanism for a variable displacement engine. The proposed engine is designed to meet client criteria of maximizing fuel efficiency as well as power output by varying piston displacement of the engine. The team was assigned to create a throttling mechanism and actuation system that work together to change the displacement.
The proposed engine is a linear engine similar to the Duke Engine currently being researched. However, the proposed engine is an advancement on this technology due to the client’s unique concept of using wobble plate technology found in axial pumps and integrating it into the engine to create the varying piston displacement resulting in maximum power and fuel efficiency.
The current design that the team is pursuing is based on the use of a worm gear actuator mechanism to lift and lower the wobble plate. A six bar mechanism has been designed to be paired with the engine.
The GE-6 Challenge team members are currently working on the design and mathematical model for a stable lift piston control system using worm drive actuator in place of hydraulic valve actuator systems. Also, a throttle idling mechanism controlled by a six bar linkage system is utilized in the design. These two systems will work simultaneously to provide the desired throttle and engine displacements relative to foot pedal motion. In order to properly size the lift mechanism, detailed analysis of the forces on the wobble plate and lift mechanism have been conducted. The throttling mechanism was chosen due to its ability to yield the proper amount of dwell in the throttle cycle and its simplicity of design compared to a cam actuated mechanism.

2017Wheelchair Dynamometer
PROJECT SUMMARY
TECHNICAL APPROACH
The purpose of the project is to produce a device that
will provide a recreational activity for those who have
their mobility restricted to a wheelchair. The deliverable
will be a bilateral dynamometer that would provide
cardiovascular exercise and gather data as feedback for
the user. A model was completed in 1993 that only
allowed for a specific wheelchair model. Therefore,
compatibility with the multiple kinds of wheelchairs
commonly used by the student athlete community is
crucial. This project follows the direction of work
completed during the Spring-Summer 2017 senior
design cycle.
We gratefully acknowledge the helpful guidance of our
client Tyler Garner and faculty advisor Dr. Robert L.
Woods.
The following major requirements were taken into consideration for the
new design: compliance with a wide range of wheelchairs, close
simulation of normal wheelchair use, a convenient user interface, and
OSHA compliant ramps. To accommodate ramp changes and a wide range
wheelchairs, significant changes to the inherited design were required.
Moreover, a sample of chair dimensions indicated significant differences
from prior assumptions. The structure was widened and roller geometry
adjusted to accommodate these dimensions.
Close simulation of normal wheelchair use requires the wheelchair to
“coast” as it would during normal use. Rather than increasing the
rotational momentum of the rollers to simulate this, our electrical
engineering team will incorporate dynamic resistance to simulate inertial
effects. Finally, as the dynamometer will offer variable resistance based on
the user preference, a flexible user interface was required. A pop-up
touchscreen interface was designed in conjunction with the EE team to
allow access for a wide range of users.

2017 ASHRAE 2018 Student Design Competition
PROJECT SUMMARY
TECHNICAL APPROACH
Infinite Flow entered into the System Selection portion of the 2018ASHRAE Student Design competition. The goal of the competition is toselect and analyze three HVAC systems for a four story, 70,000 sq. ft.mixed use building near Istanbul, Turkey. The competition requiredthat systems be chosen based on low life cycle cost, low environmentalimpact, comfort and health, creative high performance green designand synergy with architecture.
Given the mixed use nature of the building all systems chosen will behybrid systems consisting of several sub-systems. Three separateconfigurations of sub-systems will be analyzed based on the previouslymentioned ASHRAE criteria.
Load calculations were completed using Trane’s Trace 3-D software.The software will also allow for cost analysis and system designselection and testing.
Infinite Flow designers met with engineers from several companies in the Dallas/Ft.Worth area to better understand HVAC design, become familiar with ASHRAE, andlearn about HVAC modeling software. Infinite Flow designers received HVAC trainingclinics from Trane professionals in order to become familiar with HVAC principles.Trane Trace 3-D software was obtained for heating and cooling load calculations.Several meetings with industry professionals and Infinite Flow research was completedto narrow down the potential systems. Analysis based on the requirements of theASHRAE competition will be conducted for the three systems and a decision matrix willbe completed in order to pick the best system out of the three analyzed.
