Advisors/Mentors: Molly Smith, Lloyd Crask
Project Summary: Our project is a 4-story residential building aimed to provide the Fresno State students living on campus with a comfortable housing option integrated into the campus lifestyle. The building will successfully house over 625 students in bunk beds and single beds contained within over 300 dorm rooms. This luxury building features elements designed to allow each person to socialize with their fellow students. The design flow and multiple study areas will maximize student success by providing quiet spaces needed for studying. A recreation lounge, three multipurpose rooms of varying sizes, a learning center, a large communal kitchen, multiple classrooms, common areas, laundry facilities, and a coffee house on the first floor will create a “home away from home” for newly independent students. Deluxe Builders designed this building with the goal of LEED Gold status. We will build it with sustainability in mind. A structural steel superstructure with a brick veneer and metal siding exterior will create a visually appealing and efficient building located on the Southwest corner of the Fresno State campus. Multiple windows will allow for sufficient light and serve as a cost and energy-efficient method for maintaining a comfortable interior atmosphere that reduces the need for excess lighting. Deluxe Builders is a company experienced in residential facilities and design-build projects. We are excited to work with Fresno State to create their vision of a functional and elegant housing option for their students.

Advisors/Mentors: Molly Smith, Lloyd Crask
Project Summary: Our capstone project, for construction management and architectural studies  undergraduates, is to design, estimate and schedule a new student housing project. The project is  to demolish the existing Baker, Graves and Homan Hall with the intention of replacing them with new and improved student living quarters. This is to be done in a matter of three phases and our focus is on phase one. The plan for phase one is to demolish Homan Hall and the existing pool. Our team’s approach is to focus on incorporating sustainability, student input, efficiency, accessibility and overall unity. Our team believes that these capstones will ensure that the new design will be utilized to its full potential and be embraced by everyone who uses it. To give you a sneak peek, we plan on making the new dorms complement the new architecture popping up on campus while still implementing elements that pay homage to the history of the site and what still remains on campus.

Fresno State Student Housing
Students: Yazmin Guerrero, Ashley Ibarra, Jacob McIntosh, Lupe Mojica, Marcos Ventura
Advisors/Mentors: Molly Smith, Lloyd Crask
Project Summary: As California State University Fresno grows exponentially, the new student housing center location becomes more critical as there are limitations in new land developments. As a result, the proposed student housing center will be at the demolished Homan Hall, south of the existing Graves Hall building. In addition, the proposed student housing center will have three different construction phases. For this project, Exico Construction will focus on student housing for phase one of the project. Phase one will be a student housing center with the capability of providing five hundred beds and a total of 6,000-square-feet of community space. The student housing building will consist of three floors and a basement that will include an assortment of commodities. The student housing center will maintain a budget under $55,000,000 while also achieving gold LEED certifications. Moreover, the student housing center will have an exterior enclosure of tilt-up concrete and tempered glass windows. In addition, the student housing center will have parking spaces for bicycles and eco-friendly landscaping. The student housing will also have a white roof finish which should lessen the need for air conditioning and electricity overall. All of our decisions have been based on the overall experience for the residents and community users by exceeding requirements and providing the most useful and multi-function building.

New Fresno State Housing
Students: Anthony Sousa, Jordan Vasquez, Logan Fisher, Samantha Delgado, Daniel Delgado, YaQuelin Murillo, Michelle Veras
Advisors/Mentors: Molly Smith, Lloyd Crask
Project Summary: CM 180B is the second part of the construction management major capstone class. In this class, students are supposed to use the knowledge they have gained during their studies and their group work abilities. Students are assigned different roles as part of their group company and given responsibilities based on that roles. Some important roles assigned are project executive, scheduler, estimator, architect, drafter, project manager, and preconstruction manager. During the first part of the class, CM 180A, students were divided into four groups of about 5-6 students and tasked with working as a company to put together a Statement of Qualifications (SOQ) to qualify to be able to bid on the new Fresno State Housing project. In the SOQ package, every company had to include their team resumes, previous projects completed/experience, team statements and licenses, and a conceptual design of the project. Once all required information was submitted, each team presented their project to the owners and answered any questions regarding their company or qualifications. During the second part of the class, CM 180B, each company is working on putting together a Request for Proposal (RFP) package for the owners in which they have to provide a proposed design, schedule, and estimate to try and secure the Fresno State Housing project. One of the best benefits of this class is getting to work in close-knit teams like we would in the real world. We also experience working between different disciplines like construction management and architects. Another benefit is getting to speak with industry professionals. This allows us to get real work feedback and helps us improve our skills and ultimately our final product for this project.

The Redevelopment of Vacant Structures As a Solution to the Central Valley Housing Crisis
Student: Matt Gomes
Advisor/Mentor: Dr. Sagata Bhawani
Project Summary: Due to rising costs of living and lack of access to competitive wages, California is facing a major housing crisis. While the Bay Area and Southern California regions have already begun to take steps to address this crisis local to their respective regions, the Central Valley has the opportunity to learn from approaches developers in these regions have taken to address this issue and adjust them to fit the needs of the Central Valley. One such approach and potential solution to this crisis is the use of mixed-use development, which vertically combines residential and commercial space in a limited footprint. While the Central Valley does not face the same challenges with regard to shortage of space, it does tend to fall behind economically. Therefore, the concept of mixed-use development can be adapted to fit the needs of the region, specifically with regard to the conversion and redevelopment of existing abandoned structures throughout Fresno County. This project explores the impact this type of development could have on the housing crisis local to the Fresno County area. With information from local jurisdictions regarding the quantities and types of abandoned structures largely in low-income and industrial areas paired with literature regarding the successes other communities have had with this approach, we can begin to assess and quantify that potential impact. The results of this study suggest that, in fact, mixed-use redevelopment of abandoned structures is a viable, effective and sustainable strategy to lessen the effects, if not mitigate the housing crisis locally.

Shallow Subsurface Artificial Groundwater Recharge (SSAGR)
Student: Sam Hawley
Advisor/Mentor: Cordie Qualle
Project Summary: Shallow Subsurface Artificial Groundwater Recharge (SSAGR) is a simple concept. We use leach lines to percolate recharge water in agricultural fields below the crop root zone. SSAGR utilizes the existing pump and filter infrastructure of a field’s drip system to deliver water to the gravity-fed leach lines through a standpipe. The advantages of SSAGR are: 1) it is below the root zone, so it does not impact crop health and it does not leach residual chemicals and nutrients into the groundwater, 2) it does not impede access, or use of the field due to flooding, and 3) it delivers nearly 100-percent of the recharge water for percolation to the groundwater table. Our research will be successful if we can show that the cost per acre-foot for SSAGR is competitive with other forms of recharge which could open many acres of farmland for recharge where soil strata are appropriate. Our work is focused on researching the efficiency and cost of the SSAGR system in terms of acre-feet of water recharged as a function of the cost to recharge the water. A water balance is used to calculate the net water recharged and actual construction and operations costs are used to determine the cost to recharge the water. The poster presentation illustrates the SSAGR system, its groundwater recharge performance, and operations costs.

Autonomous Smart Agricultural Robot
Students: Nicholas Amely, Yue Yang, Vidith Balasa, Jonathan Vazquez, Lawrence Rede,
Luis Villanueva, Cristian Mora, Lauren Main, Joel Velez, John Estrada, Pauline Estrada
Advisor/Mentor: Dr. Hovannes Kulhandjian
Project Summary:
Farming is a very complex process that requires a large amount of different tasks to be performed regularly and effectively to keep it running. These tasks can be very difficult for people to do for long periods of time, and yet many of them are carried out entirely by manual labor. The advancement of Agricultural Technology (AgTech) in the recent years has increased farm productivity and replaced manual monotonous tasks that are unsafe or inefficient for farm labor workers to do by hand. Our proposed solution uses Artificial Intelligence (AI), machine learning, LiDAR, Internet-of-Things (Iot) sensors, RGB and depth cameras, and a smart robotic arm all implemented on a Farm-ng Amiga robot framework to perform multiple intelligent farming tasks autonomously and effectively. The purpose of our autonomous and AI-based robot is to make multiple major farming processes more efficient, cost effective, accurate, and humane, as well as to perform some new farming processes that are not widely explored.

Handheld Vehicle Controls
Students: Joe Garza, Anthony Herrick, Jesus Meza
Advisor/Mentor: Dr. Aaron Stillmaker
Project Summary: The process of driving any type of motor vehicle has been virtually unchanged for about 100 years. One would use their feet to work the accelerator and brake pedal, whereas they would use their hands to turn a steering wheel to maneuver and control the vehicle. The process itself has not changed, but with advancements in driving technology, these “mechanical” actions have been digitized through electronic sensors, servos, motors and electric pumps. This begs the question, when does the process of driving evolve with the technology we are controlling? With driving being a full-body experience, nearly 25 million people of driving age possess some form of disability that limits or inhibits their ability to drive. Handheld Vehicle Controls, HVC for short, is intended to eliminate the need to use your legs to drive by putting all major vehicle controls at your fingertips. The HVC device would override the sensor inputs traditionally given by pressing one of the pedals by using triggers placed behind the steering wheel. The accelerator trigger would control the throttle using your fingers’ pressure as an analog input and converting it to a digital signal between 0 volts and 5 volts. The braking pedal cannot be controlled with digital signals since it is mechanical feedback connected to a hydraulic pump. We will incorporate a digital method of applying the mechanical force to the pedal to bypass this barricade. We will use a 12V-rated DC brushed motor to drive a gear reduction set to apply the needed force to the brake pedal. The initial vehicle for testing and simulation would be a 2014 Honda Accord EXL V6, which utilizes J2534 OBDII communication protocols that can be read and written to using various softwares. Although not necessary for “rudimentary” implementation, the data from the OBDII port of the vehicle will be used to monitor live vehicle data and serve as “read” data rather than “write” data. Upon finalizing our materials, the HVC device will be centered around an STM32-Nucleo F446 microcontroller, several breadboard circuits that will control the braking and throttle overrides, triggers for input and OLED screens. Overall, the project is intended to be an accessibility device for those who cannot drive through traditional means or to change the driving technique that’s been in use for so long.

Smart Ranch
Student: Gabriel Aguilar, Oscar Vazquez De Leon, Anthony Sanchez, Brenden Simpkins
Advisor/Mentor: Dr. Shahab Tayeb
Project Summary: To reduce the unused arable land in semi-rural neighborhoods, by reducing the manual labor required to work the land, an Internet of Things (IoT) network was created. A collection of sensors and actuators are networked together into two or more wireless local area networks (WLAN). The WLAN used within the target home uses WiFi as it is a common consumer IoT electronics protocol to allow compatibility with off-the-shelf IoT devices. The outdoor WLAN uses Long Range Radio (LoRa) to allow for packet transmission over an extended range resulting in more power-efficient transmission when compared to other protocols such as WiFi. All the devices on the garden WLAN are powered with rechargeable batteries and solar panels to allow for mobility. The garden network gathers agricultural related data (soil moisture, soil temperature, ambient temperature, ambient humidity, light intensity, etc) using sensors while regulating the water consumption used during irrigation with a valve and drip irrigation setup. Data-gathering sensors and actuators will automate many of the daily tasks that come with trying to raise a garden or farm. To support these features a remote server (Firebase) is used to manage the databases, host website, and generate analytics for the network. A graphical user interface (GUI) was developed using JavaScript, HTML, and CSS to allow the user to access the network remotely as a website. Access to the interfaces allows for the viewing of raw data, analytics, controlling actuators, configuring automated schedules and other systems. The created network will be tested to determine improvements in water consumption, power consumption, data throughput and other factors that can make the arable land easier to manage for crop growth for the landowner.

Smart Zoo
Students: Puya Fard, Rafael Hernandez, Dominic Keifer, Sahildeep Singh
Advisor/Mentor: Dr. Shahab Tayeb
Project Summary:This is a project conducted by three computer and one electrical engineer major student. It is called the ”Smart Zoo” which will focus on monitoring, collecting, and storing data, which will be used for the purpose of controlling the system or environment. This project uses embedded systems, cloud-based programming, and a software-based user interface that will be developed using C++, Python, and HTML. This project will aim to assist zoo workers and the zoo itself by creating a smart control environment that will protect sensitive zoo animals’ safety. The method of design is described as the following: the data flow is done by first collecting data from the physical sensors configured in an Arduino UNO Rev2 microcontroller. Then the collected data will be stored in an external SD card storage that is also connected to our microcontroller. Moreover, the microcontroller will transfer this data to a collective database in the AWS cloud, which will also include machine learning to predict water and air temperature depending on other variables, along with storing all the data sent by a microcontroller. Finally, data stored in the cloud is going to be accessible via a permitted user connected to the internet using our own implemented website or mobile app. Ultimately the user will be able to monitor the data as well as send back an actuator input feedback to change the temperature of the corresponding habitat of the animal. From a safety perspective, this project emphasizes the need for an educated zoo keeper that will identify critical changes that occur to these habitats to take impactful action with the help of our controlling method. We must also keep in mind that the changes made to the environment will directly affect these animals on demand. Each smart system will cost between $250-300 depending on the quality of the sensors used for the designated zoo animal.

Solar Improved Electric Plane
Students: Roberto Cazares, Raymond Kober, Jason Lawrence, Long Lor
Advisor/Mentor: Dr. Woonki Na
Project Summary: Modern electric planes are limited in range and flight time due to the power density of batteries. The Solar Plane Team’s project utilized a dual power system,  panels along with auxiliary components, to improve the flight duration of electric aircrafts. The team utilized a scaled and modified version of the Magnix Electric Cessna Grand Caravan aircraft, showing that the addition of solar panels to the airframe of the aircraft would help improve the flight durations of modern electric aircraft. The team made modifications to the RC plane which involved adding solar panels and modifying the existing power system to accept the additional generated power. Solar panels were placed along the wing and fuselage of the aircraft. The battery was connected in parallel with the solar panels through a buck DC-DC converter. The power output of the solar panels were monitored by a Raspberry Pi Pico microcontroller to test power usage during the flight. This data was stored on a removable SD card and analyzed to determine the plane's overall power usage. Overall, the team presents a modified RC plane that has an extended flight range due to the addition of solar panels. These modifications could then be scaled up to electric aircrafts currently in production, adding to the impact that electric aircraft have towards a more sustainable aviation future.

Standardization of the EV battery packs benefit both, the users and manufacturers of EVs.

Battery Tester
Students: Catalina Arriaga, Anthony Barba, Brandon Hill, Bien Ly, Rupinder Siddhu
Advisor/Mentor: Dr. Yuanyuan Xie
Project Summary: To better optimize and improve the operations within Fresno State’s battery lab, a universal battery tester was designed to simultaneously charge and discharge four batteries of various sizes from electric vehicle/hybrid battery cells to regular household batteries. The battery tester is controlled by a computer program housed in an Arduino UNO REV 3 microcontroller that will record time and collect the various resistance, current, and voltage readings of the battery terminals. The readings from each terminal are displayed on a 20x4 LCD display. The battery tester is composed of a 3D printed rectangular casing using Grey ABS filament 1.75mm. To formally hold the batteries in place, a spring system exists that allows adjustable sizing for batteries up to 3 inches in length while a clamping system will be used to hold the center of the cells. Additionally, batteries with different terminal shapes such as circular, square, and hexagonal are also accommodated. The tester utilizes potentiometer for altered charge/discharge rates in conjunction with breadboard.

EV Battery Swapping
Students: Ahmed Baluch, Taylor Heaton, Ayyaz Mahmood
Advisor/Mentor: Dr. The Nguyen
Project Summary: As electric vehicles have become more popular over the last two decades, several issues have arisen. For example, passenger vehicles like the Tesla Model 3 take on average 15 minutes to charge the battery enough to drive 200 miles. Faster charging can be used, but this comes at the expense of battery life. In order to overcome this issue, the team has developed a compartment that was designed to allow for modular battery swapping. Using the frame dimensions from the Tesla Model 3, three main subassemblies were developed for this compartment. The first assembly is the top cover assembly, and it is responsible for latching onto the swappable modules. It is driven by a belt and pulley system. The second assembly is the frame assembly, and it was designed to provide structural support for the modules and other assemblies. Custom cuts and brackets were used to assemble it. The last assembly is the door assembly. This assembly was constructed using a system of pneumatic cylinders, and it was designed to swing underneath the compartment and provide accessibility to two modules at a time. Materials were sourced from local vendors as well as online sources. Using Arduino boards, the systems were programmed to actuate the cylinders and other mechanical components. Finally, testing was done after the fabrication stage to check the viability of the prototypes. The designs were then updated using the results from the testing stage.

Field Van Chair Design
Students: Liam Gutierrez, Atish Maman, Ian Rodrigues
Advisors/Mentors: Dr. The Nguyen
Project Summary: Field Van, a custom camper van dealership, sponsored a project with the objective to design and build an attachment for their vehicle seat that would allow it to be used as an outdoor rocking chair. The design was projected to be either an attached and stowable mechanism on the seat itself or a separate detachable base that can be stored away within the vehicle. The product would be made available to new and existing customers either pre-installed or as an add-on option to their seats. First, a scaled 3D printed model was made in order to grasp an overview of the design. Next, a full-scale wood model was constructed to observe the predicted motion of the system revealing movement constraints that were remedied in the final prototype. Penultimately, a final prototype was constructed out of aluminum to test the design in its  entirety, including function and aesthetics. Lastly, the final product achieved was an attached, stowable, gliding mechanism capable of stowing away compactly and providing a comfortable seating experience inside the van and in the rigors of the outdoors.

Implementation of a Total Variation Diminishing (TVD) Scheme for Discontinuity- Capturing of a First-Order Advection Equation
Student: Yi Hao Xie
Advisor/Mentor: Dr. Deify Law
Project Summary: One-dimensional advection equation with a step wave (discontinuity) propagating to the right will be numerically captured using total variation diminishing (TVD) scheme with second-order Lax-Wendroff scheme. The numerical solution will be compared with the analytical solution of the one-dimensional advection equation with a step wave. The TVD scheme is a finite volume method that can provide highly accurate numerical solutions for a given system, even in cases where the solutions exhibit shock waves, discontinuities, or large gradients. Superbee, van Leer, and minmod flux limiter functions will be studied and compared. Applications include supersonic and hypersonic gas dynamics where shock waves tend to occur over the surface of flight vehicles or inside an isentropic nozzle.

Leprino Water Treatment
Students: Wyatt Jones, Thathsara Kumara, Jonathan Swanson
Advisor/Mentor: Dr. The Nguyen
Project Summary: Water conservation is an important issue in California as water resources are limited and expensive. Leprino Foods proposed a project to recapture and treat drained water from their clean-in-place (CIP) systems. It will be reused for future cleaning in their whey production facility to increase their sustainability and water conservation. The company’s estimated recapture CIP waste is approximately 600k gallons per day with an estimated savings of $633,706.6 per year ($3.74/1000 gallons) with an ROI of 18.1% per year and capital investment of $3.5 million. According to our current data analysis, the estimated average reclaim reaches 608,686.07 gallons per day with an estimated saving of $830,786.27 per year with an ROI of 23.74% per year. The final design is a 3-stage system: collection, filtration, and redistribution. The collection stage recaptures CIP water flushes that occur between chemical cleaning from several equipment centers and stores the water in one of two 60k gallon water silos. Average flow rates and operation times were analyzed to determine proper pump and pipe sizing. The filtration stage uses ultrafiltration, reverse osmosis, and ultraviolet treatment to restore the collected water to Pasteurized Equivalent Water (PEW) standard. Sampling and flow rate data provided by Leprino was used to determine the best options with vendors. The redistribution stage pumps the clean water to existing water silos that distribute PEW standard water to CIP equipment. Integration into the CIP delivery system allowed for the use of pre-existing pipe work. Analysis of Leprino’s operation schedule was cross-examined with PEW water silo levels to time the delivery of filtered water.

Leprino Foods VIP Internship: Distribution Circuit Breaker Modernization
Students: Bilal Anwar, Induwara Rekogama
Advisors: Roger Moore, Gregory Beyersdorf, Antonio Urrutia Chavez
Project Summary:
The purpose of this project is to replace the power distribution circuit breakers with a better design and install an up-to-date power monitoring system. The current breakers are bolted buss design which are highly obsolete and require an extensive downtime for maintenance. The new breakers will reduce the downtime by approximately 80% and include a power monitoring system which will allow the optimization of power delivery to different departments. The replacement will be accomplished by doing a circuit breaker retrofill. This will be done by measuring the circuit breaker dimensions and wiring to create a new circuit breaker cassette that can fit in the space remaining from the obsolete bolted buss circuit design. This new design will allow the circuit breaker to be isolated in one section and easily removed compared to the old design which is connected to the entire bus.

Plasma-Based 3D Printing
Students: Giancarlo Kamesch, Kaiyu Vang, Derek Xiong
Advisor/Mentor: Dr. Sankha Banerjee 
Project Summary: Polymer and polymer composite-based 3D printed materials provides consumers with the opportunity to manufacture multiple prototypes and proofs of concept, making it an excellent method for testing design concepts. However, the layer-by-layer printing procedure can result in a weakness that reduces the strength of the finished printed pieces. To address this issue, the team will be treating the surface of the printed samples with room-temperature plasma Corona Discharge to evaluate the effects of plasma-treated plastic filament compared to non-treated surface samples. This will involve tailoring the polymer properties in the layer-by-layer process to create stronger and more cohesive bonds between each layer that is printed over the previous. By doing so, it is expected that the strength of the finished product will be increased. Additionally, the team will be conducting further tests to determine the optimal conditions for plasma treatment and to assess the durability of the printed pieces under various stress conditions. This will provide valuable insights into the potential of plasma treatment as a solution for improving the strength of 3D printed pieces.

Thermal Sleeve
Students: Hayley Kumagai, Timothy Peasha, Jaden Uphoff
Advisor/Mentor: Dr. The Nguyen
Project Summary: Current methods for thermal therapy applications either lack a constant temperature source or do not cover a larger surface area. A thermal therapy sleeve was designed to address these limitations using thermoelectric components that fit the length of the forearm. The device uses Peltier tiles to evenly distribute the temperature treatment across the forearm. The user sets the temperature and duration of the system based on recommended limitations for the human body. Preliminary prototyping demonstrates a potential for success for the device if pursued with more advanced materials.

A Water Piston Engine
Students Daniel Fishback, Thomas Johnson, Chace Lee, Cesar Lemus, Emilio Marquez, Davit Sargsyan, Sharath Kulkarni, Manuela Mendolicchio, Yishen Shao.
Advisors: Dr. Yuanyuan Xie, Dr. Tom Burns, Dr. Jian-Qiao Sun (UCM)
Project Summary:
This project aims to create a utility-scale energy harvesting system to extract kinetic energy from slowly flowing water at low-cost. The project product consumes drag as fuel and transforms slow moving water flow to useful power (e.g., electricity). The developed system uses a pair of lightweight soft parachute assemblies to drive an electrical generator. These assemblies operate in a reciprocating motion where the open chute drives the system and the closed chute trails behind. At the end of each stroke, the open chute closes and vice versa, ensuring a constantly moving system. At the full scale of 30” tube diameters,, calculations show a theoretical power generation of 1.7 kilowatts.

Water Treatment System
Students: Nadine Barton, Luis Cordova, Jose Guerrero, Abel Lopez
Advisors/Mentors: Dr. Yuanyuan Xie
Project Summary: The lack of water resources is an ever growing concern not only in California after years of recurring droughts but also in the rest of the United States and the world. The goal of this project was to integrate two preexisting water filtration systems to lower the total dissolved solids (TDS) in recovered irrigation water. One filtration system is a nanofiltration system composed of graphene nanoplatelets, activated carbon and filter paper. The other filtration system is a micro-plasma based treatment process. A robotic arm is also used to monitor the system. The combined filtration system should lower the TDS levels of the water to under 500 parts per million (ppm). The final order and combination of these systems was determined by testing each system individually and in combination to determine the most effective integration.

Collapsible Mirror
Charon’s Crew: Amrit Singh, Joshua Phrachanhsay, Kyle Lor
Sanger High School
Project Summary: NASA wants to develop sustainable lunar bases using bricks comprised of melted plastic and lunar soil. However, unlike on Earth, space has no convenient heating methods such as ovens or stoves. In order to create the bricks, efficient, lightweight, and collapsible equipment is required to redirect and focus the sunlight to heat the mixture of lunar soil and plastic as needed. The proposed design seeks to make a solar trough from parabolic mirrors that collapse linearly in which Fresnel lenses will be located on top. A pipe containing the brick mixture will be in between the Fresnel lenses and the solar trough. This design aims to utilize sunlight in two ways: concentration and reflection. The Fresnel lenses concentrate the sunlight onto the pipe, and any missed sunlight will be reflected back to the pipe due to the solar trough. This method of heating creates an efficient solution to NASA’s goal.

Dust Remover
EXO: Anthony Cantor, Afton White, Antonio Jose Padilla
Sanger High School
Project Summary: Ever since the Apollo era from 1969-1972 to the present, NASA has stated that lunar dust damages their solar panel. Dust affects them not only in space but here on Earth. Compared to dust on Earth, lunar dust is very jagged and abrasive to the touch, making it harder to clean. So cleaning it with a brush could scratch and damage the panels even more. A solar panel’s efficiency drops by 40% due to dust which does not allow the rover to run at its full capacity. We are using an inflatable bladder to stretch a fabric above the solar panel, when the fabric is stretched its woven holes are exposed allowing dust to be trapped once deflated. We found that we needed to have multiple passes in order to remover over 90% of dust.

Insect NanoLab
The Beetles: Kaleb Cole, Brayan Nunez, Diego Ramirez
Sanger High School
Project Summary: Around the world, an estimated 2 billion people lack access to sufficient food, and by 2050, Earth will need to have enough resources to sustain 9 billion people. We use half of our habitable land to support livestock farms that only produce 18% of the world’s calories. On the ISS, agricultural land is limited, and a solution to this problem is alternative protein sources. In our prototype, we raised crickets as our alternative protein due to their high protein content per gram of insect. Our purpose was to create a design for NASA that would be suitable in outer space and for use on Earth. Utilizing electronic systems within our NanoLab helped ensure proper conditions are met to keep the insects alive, including a camera to monitor cricket growth.

Lunar Habitat Table
Cosmic Solvers: Simone Kilby, Giovanni Lopez, Leonardo Barraza
Sanger High School
Project Summary: NASA seeks a collapsible, lightweight, and functional table for its lunar habitats. Our goal was to create a table that maintains stability in low gravity situations, as well as being transportable with multi-functions. As a team, we researched previous table patents to find ideas and inspiration for our prototype. We created a one-of-a-kind solution that met the prerequisites, all while considering the difference in gravity. Regarding the resource NASA provided, we used an umbrella-like design created out of Delrin and 3D-printed parts. Our table takes five easy steps for set up and take down. Despite our lightweight design, we still met the requirements to be able to withhold up to 100 pounds. We feel we have met the NASA requirements and are supported by the table's secure compacted design. The design delivers a simple and accessible table that still maintains the crew's living functionality.

Lunar Worktable
Three Planeteers: Angel Razon, Angad Gill, Antwon Leonardo
Sanger High School
Project Summary: According to NASA, The Astronauts for the Artemis launch, which will be launching from 2022 to 2027, will need a worktable to make repairs. The worktable needs to be portable and have working wires, outlets and a retractable reel. We researched previous patents for worktables to find inspiration and ideas the prototype. We made a worktable with detachable magnetic legs and a backboard. The magnetic legs allow for easy manipulation of the legs. The backboard serves to prevent items from falling off the table and can extend the table if extra space is needed. The reel is able to retract the extension cord by manually moving the reel. We feel the design for the worktable meets NASA’s requirements as the design provides easy to manipulate and portable worktable.

Lunar Work Table with Power
JTS Artemis: Octavio Arevalo, Gabriel Cisneros, Jaden Velez
Sanger High School
Project Summary: NASA wants a multi functional work table they can use when constructing their base. They want a table that allows power to run through it (from the Lunar Rovers Bigger Batteries) to power their tools. The requirements consist of a light source, a reel for the plug, 2+ outlets, 4m of cord, easy to manipulate with big gloves, and dust protection. Our illumination design consists of a light source that bounces off aluminum from the top of the table to shine further around the area. The legs nest upon each other and unfold in different directions to provide stability for the table. The table has two outlets on two sides and a hole for the extension cord on one side. Our table only weighs 17.8 lbs., allowing for easy transportation. Our design meets NASA’s requirements and is proven to work with the utmost efficiency.

Micro-Gravity Dice
Roll With It: Isaac Silva, Gabriella Avila, Aaron Rojas
Sanger High School
Project Summary: NASA needs a way to use dice in micro-gravity, so they can have team bonding activities. Our goal is to have a compact design that randomizes any type of dice, and catch it to read the numbers. As a team we looked at previous patents to know what type of things to stay away from when making this idea. We wanted to make something that was original. When we finally settled on an idea, we started making our Piston Design. During this proses there where many features that where added, including our cone design to catch D4’s. Our deign is very simple, all someone has to do is take the bottom acrylic off to put their dice in. After you replace the lid all you have to do is shake. Once you shake to your desired amount then you push the piston closed. At the bottom you will be able to read your number. We feel our design meets NASA’s requirements, as supported by our Not Not Random Test and the games of Monopoly we played. The design delivers a simple shaker piston design for all types of dice.

Microgravity Dice Rolling
Deimos Dice: Adrian Hernandez, Austin Griesner, and Sarah Perez
Sanger High School
Project Summary: NASA needed a functional yet fun way to contain dice in microgravity. When starting this process our goal was to create a dice container for microgravity in order to decrease mental health issues often caused by spending extended periods of time in space performing both physically and mentally demanding tasks. Our design consists of a hexagon shaped container with a wall placed in the middle to prevent the dice from being jumbled together. We also used a slider in order to separate our magnetic surface and our metal dice, allowing our players to shake the container and release the slider when they are satisfied with their roll. We have also tested randomization order to ensure no number bias to recreate traditional game play.
