Energy Monitoring & Management System (EMMS)

Bennett A. Andrews, Seth Wilcox, Zachery D. Holsinger, Ben Weaver, David C. Williams, and Tom Austin

The Energy Monitoring and Management System (EMMS) is developing an electrical power meter to help make electricity more available in energy impoverished regions of the world. The meter fills a unique niche for energy tracking and regulation within micro-grid systems. The EMMS project has partners in Burkina Faso and Zimbabwe: Open Door Development (ODD), the Institut Missiologique du Sahel (IMS), and the Theological College of Zimbabwe (TCZ). Ties are also maintained on a regular basis with IEEE Smart Village for potential future widespread system implementation.

Recent work on the EMMS meter has been focused on resolving the last few remaining bugs, establishing a robust communication system, and developing a centralized server-based interface which aids with meter configuration and administration. The team has also begun several future developments which include datalogging and remote access features.
Rapid Orthotics for Cure Kenya: Mechanical Design and Modeling of 3D Printed Sockets

Joey D. Andrews, Rachel E. Bruns, Lauren N. Seubert, Jarod A. Snader, Gabi E. Griffith, Elizabeth G. Hargrove, Brandon J. Weindorf, and Jamie R. Williams

Rapid Orthotics for Cure Kenya (ROCK) works with CURE, a non-profit orthopedic workshop in Kjabe, Kenya, to implement a 3D printing system for manufacturing custom prosthetics and orthotics. The goal is to reduce the production time and cost for the current transtibial sockets being manufactured in the orthotic clinic to give the patients a way to integrate into society and reduce stigma from their communities. The team has developed a transtibial socket for below-the-knee amputees produced by a 3D printing system that converts a scan of the residual limb to a model that takes a third of the time to print versus the current manufacturing method. The current focus of the team is to develop a rigorous testing procedure adhering to the requirements set by the ISO 10328 Standard, an internationally recognized testing method. In order to ensure the safety of the sockets, tests must be run demonstrating that the product can withstand the different forces experienced during the gait cycle. Due to the complex geometry of the applied forces outlined in the ISO 10328, the team has designed a novel testing rig that interfaces with the MTS machine at Messiah University to apply the necessary forces according to the geometry outlined in the standard. Additionally, computer-based simulations are being developed in SolidWorks, a 3D modeling software, to determine how the components will behave under certain loading conditions. This is done to ensure accordance with the 10328 Standard and will be critical in the future for developing necessary cyclic tests.
Designing a Locally Manufacturable Wheelchair for Nepal

Ethan M. Barnes, Levi D. Hauger, Cade K. Bender, Harrison J. Crosley, Riley Harro, Joshua J. Holley, Peter C. Hopkins, and Timothy J. Van Dyke

Persons with disabilities in developing countries often lack the basic equipment needed to assist them in their daily lives. International Nepal Fellowship (INF) is a Christian medical organization located in Nepal that provides medical care and assistance to people with disabilities and other conditions. Currently, INF imports expensive wheelchairs that undergo a prolonged border process before being received. INF has reached out to the Collaboratory to design a wheelchair that can withstand the challenges of Nepal’s terrain and can be manufactured from local materials. The Nepal Wheelchair team accepted this challenge and set out to design a wheelchair that can fulfill their needs. The team began by researching wheelchair models for inspiration and eventually settled on two preliminary designs. In January 2020, the team traveled to Pokhara, Nepal to gain feedback from the staff at INF and select a final design based on their comments. During this trip, the team acquired and brought back locally available materials and parts available in Nepal in order to construct a prototype. This year, prototyping has been completed for the following elements: the central frame, wheel lock, footrest, wheel mounting assemblies and armrest fixtures. As a result of knowledge gained during prototyping, some design changes to the wheelchair have been made. Moving forward, the team will test the overall prototype for durability and prepare a manufacturing manual for INF.
Village Water Ozonation System

Grant Brubaker, Ruth C. Galyen, Sam B. Stone, Benjamin K. Burlew, TJ J. Malanga, Ray Knepper, and Michelle L. Lockwood

The Village Water Ozonation System (VWOS) team’s core mission statement is to provide economically sustainable and culturally sensitive drinking water solutions for communities, to empower communities with the ability to properly maintain their drinking water supply, and to transform people’s lives by decreasing the occurrences of waterborne diseases.

Currently, the VWOS team is partnering with Friends in Action to design and implement two drinking water treatment systems for the community living on Rama Cay, an island in the Bluefields Lagoon on the eastern coastline of Nicaragua. The wells on the island are contaminated with E. coli and other bacteria and contain high levels of salt that cause the water to be unhealthy, distasteful, and corrosive to metal equipment in the system. The team hopes to design a system that will disinfect the water, remove salinity from the well water with a safe and efficient disposal of all byproducts, and decrease corrosion agents.

VWOS is partnering with Forward Edge International for the third time (Nicaragua 2009 and Mexico 2016) to design water treatment systems for communities in Oaxaca, Mexico and Kijabe, Kenya. The system for Oaxaca is ready for implementation and awaits availability to travel. The system for Kijabe is in the initial stage of communicating with the client on specifics for the design.
Prosthetic Knee for CURE Kenya

Isaiah D. Bryner, Sarah N. Kelchner, Carter D. Urich, Samuel R. Burgess, Nathan E. Jaloszynski, Josiah D. Moyer, Kay Laura Sindabizera, and Jamie R. Williams

Lower limb amputations are common in sub-Saharan Africa due to the prevalence of disease and infection in communities that lack access to adequate healthcare. Our project, Prosthetic Knee, partners with the CURE International Hospital in Kijabe, Kenya. In the region surrounding our client’s facility, there is a large number of lower-extremity amputations due to various infections and diseases. While many of these amputees only require a through-knee amputation, the lack of an affordable through-knee prosthesis often forces patients to undergo a more invasive transfemoral amputation to enable them to use a cheaper above-knee prosthesis. The goal of our project is to design and manufacture a financially accessible and user-friendly prosthetic knee for knee-disarticulation patients that can be manufactured in Messiah University’s machine shop (and ultimately, at the orthopedic facility in Kijabe).

This year, the team’s work has included finalizing the prototype design, conducting finite element analysis in SOLIDWORKS to evaluate the knee’s static and fatigue strength, and beginning the process of physical manufacturing. Additionally, a damping mechanism driven by a spring-loaded system has been developed and integrated into the design after completing motion analysis and SOLIDWORKS modeling. Our future goals include manufacturing a complete metal prototype of the knee, conducting physical strength and fatigue testing on the metal prototype, and continuing iterative prototyping of the damper in preparation for physical implementation.
Landmine Neutralization: Air Excavation Unit

Josh Card, Ethan R. Cornwell, Evan Poust, and Donald G. Pratt

The Landmine Neutralization team’s poster will present our team’s progress towards designing and prototyping an air excavation unit. To accomplish this, the project team is working with the HALO Trust, the world’s largest demining NGO. The HALO Trust works in many countries to remove the remnants of war, including improvised explosive devices (IEDs) and unexploded ordnance (UXOs). This project seeks to help deminers by providing a device that blows air at high velocity to clear dust and other debris away from potential IEDs and UXOs in war-torn areas to help in their effort of demining. We have focused on designing our prototype to operate reliably in harsh environments while fulfilling our client’s specifications. Our client requested that we design our excavation unit to be easily installed onto their Volvo 220 backhoes and their custom-made backhoe attachments. The current design is modular and consists of a hydraulic motor powering a fan from a backpack leaf blower, all of which is assembled within a steel frame that attaches to the rake of the HALO excavators. Due to circumstances beyond our control, our project will be wrapping up at the end of this semester, which is sooner than anticipated. This means the goals of our project have been narrowed to having a functional prototype and relevant documentation that we can present to our client.
Fatigue Testing a Mechanized Percussion Well Drilling System for Water Access in Western Africa

Micah T. Clark, Tommy Denlinger, Robert H. Donley, Benjamin R. Gates, Matthew R. Higgs, and Philip M. Tan

The Mechanized Percussion Well Drilling (MPWD) Collaboratory project seeks to design a simple mechanized well drilling system for drilling shallow water wells in Western Africa. Our client, Open Door Development (ODD), seeks to make water accessible to all in the region, but has had difficulty drilling through hard soil layers. To combat this problem, the MPWD team has worked closely with Mr. Joseph Longenecker to develop a mechanized percussion well drilling rig that is capable of drilling through these harder layers. Currently, the MPWD team is seeking to provide recommendations to improve the lifetime of our client’s new, fully mechanized rig design. This year, our team’s work has been focused specifically on analyzing the lifetime of the rig’s driveline chains and also on its frame. For the driveline chains, the team will be conducting fatigue testing on a model of the driveline system to determine which type of chain should be used on the rig. To determine the lifetime of the frame, the team will be performing a series of static, buckling, and fatigue finite element analyses on the rig’s frame. The most recent accomplishments of the MPWD team have nearly proved that their design for the loading application will be feasible for use on the actual testing rig and that multiple studies of finite element analysis can be performed to simulate the different rig frame loading scenarios.
Adjustable Prone Trolley Design for People Suffering from Spinal Cord Injuries in Nepal

Blake N. Clemmer, Abby Miller, Jared T. Pavlovich, Dylan J. Derstine, Derek A. Thrush, and Timothy J. Van Dyke

For people suffering from spinal cord injuries, it is important to stay active. However, with spinal cord injuries, the use of a wheelchair isn’t feasible. These patients require a prone trolley. A prone trolley is a horizontal pad with four wheels that a patient can maneuver and control while lying in a prone position. Our partner, International Nepal Fellowship (INF), deals directly with patients who suffer from spinal cord injuries on a daily basis. INF, a Christian, medical organization, manages a hospital in Pokhara, Nepal which specializes in treating patients with spinal cord injuries. The Nepal Prone Trolley Team’s goal is to provide our partner with a sustainable prone trolley design and create the required manufacturing documentation to enable them to produce the prone trolleys in country at their Green Pastures hospital. The team began our work by researching what a prone trolley is, how it functions and what is currently available. During the research, the team discovered that there weren’t many examples of a manually powered prone trolley or critical dimensions for ergonomics for manually powered trolleys. This drove the team to develop testing methods and preliminary designs specifically for INF. Various basic designs were considered, but, through communication with INF, a single design was chosen. Computer modeling of this design was used to decrease the overall weight of the trolley and simplify the frame. With most of the design finalized, the team is ready to begin prototyping next semester.
Sustainable Agriculture

Jacob Dean, Madalyn A. Heckman, Brandon M. Bickom, Micah J. Hess, Miggy Matanguihan, Aleesa Wu, and Michelle L. Lockwood

The Sustainable Agriculture team is dedicated to developing alternative and sustainable agricultural solutions to alleviate poverty in western Africa. The team is currently working with Sheltering Wings in Yako, Burkina Faso and Trans World Radio in Parakou, Benin. Both clients currently have a working aquaponics system, but the type of system varies between clients. Sheltering Wings has a flood and drain system and Trans World Radio has an ebb and flow system.

Throughout this year, our team has focused on reducing power consumption and costs for our clients. The development of the ebb and flow prototype was a consequence of this mission as we reduced power consumption by one pump using a manual siphon. We have also worked towards lowering the costs of water quality testing kits by introducing a Nutrient Film Technique with basil plants. Lastly, we have strived to research best practice methods for fish food making and fish feeding in order to keep the biology of the prototypes healthy. To support present and future clients, the year will conclude with final deliverables for the ebb and flow prototype including an operations and maintenance manual, a construction manual, and a troubleshooting manual.
A Sustainable Mobility Solution for Persons Living with Disability in Burkina Faso

Rachel Delate, Rachel Rashford, Joey Sinsel, Katie Bunch, Sam Fino, Faith N. Kerlen, Erin T. Logsdon, Julia M. Neborg, John Meyer, and David T. Vader

The Sustainable Mobility project of the Collaboratory empowers people living with a disability in rural West Africa to pursue educational and work opportunities and more fully participate in family and community life. Our electric, 3-wheeled, off-road wheelchair has transformed the lives of dozens of clients through partnerships with the Center for the Advancement of the Handicapped in Mahadaga, Burkina Faso and the Center of Hope in Fada, Burkina Faso. Now, to reach more people in new locations and with more partners, Sustainable Mobility is working to reduce manufacturing time and cost, author image-driven fabrication guides to enable local fabricators to build trikes, create instructional trike assembly videos, and develop supply chains to bring parts and materials to build sites. We seek to put local fabricators to work building tricycles wherever they are needed.
Panama Bridge Project

Luke T. Fetterman, Jordan T. Barner, Mikayla R. Eyster, Crosby Harro, Zachary C. Hartman, Noah Ling, Drew W. Moyer, Noah W. Thrush, and Brian D. Swartz

The Panama Bridge project has partnered with Rio Missions Panama to design a bridge for the village of La Gigi, Panama. The mountain community of La Gigi experiences heavy rainfall during the rainy seasons. A stream runs along the community, restricting their access to schools, employment options, and other communities. While passable during dry seasons, the stream floods and becomes impassable after heavy rains. The residents are effectively cut off from their livelihoods, church, health services, and other communities during this time.

To accommodate this need, the Panama Bridge Team has spent the last two academic years designing a 90 foot aluminum truss bridge. The design includes a unique construction strategy to deal with challenging site constraints.
Fluency Assistance Device (FAD): Masker Upgrades

Jake T. Finkbeiner, Chad M. Long, Corey Bean, Michael D. Jenkins, Larry A. Vegas, and Harold R. Underwood

Around seventy million people internationally have a stutter, a form of a fluency disorder. Some fluency assistance devices are available to the public, but most are highly expensive or unreliable. The Fluency Assistive Device (FAD) team seeks to assist a niche community of these individuals who currently rely on a device known originally as the Edinburgh Masker by partnering with Dave Germeyer. Utilizing his expertise in repairing the Edinburgh Masker, FAD is developing two new versions of the masker to increase its portability, functionality, and cost-effectiveness. The first is an update of the original called the Analog Masker (Version 1.1). A prototype of the Analog Masker v1.1 has been developed, tested and is currently being revised based on the results. Revisions include updating the layout of the board and finalizing the power supply circuitry. The second version, known as the Digital Masker (Version 1.0), will use a Bluetooth-enabled microcontroller to achieve masker functionality. Bluetooth audio output for the Digital Masker has been tested, and two algorithms have been created for the masking output. The supporting software for the Digital Masker is nearing completion. The schematic and the layout design have been started for future implementation of the hardware.
Design of a Transradial Myoelectric Prosthesis

Lindsay L. Haseltine, Jaymie R. Monday, Meghan L. Sampson, Sam Sparks, Samuel F. White, Eddie J. Yesilonis, and Tim Howell

Due to the rapid growth of children and the high cost of myoelectric technology, children are not given the same opportunities to use myoelectric prosthetics as adults. The Muscle Activated Prosthesis (MAP) team is developing an affordable, transradial, myoelectric prosthetic for a thirteen-year-old girl. The MAP team is designing a myoelectric prosthetic that will cost under $1,000, over 90% less than custom myoelectric devices on the market. This device has an EMG sensor, a microprocessor, a printed circuit board (PCB), linear actuator motors, and a battery organized within a 3D-printed transradial prosthesis to open and close the hand grip when the EMG detects electrical signals via muscle contractions in the client’s flexor carpi radialis. Currently, the team has fully assembled a prosthetic prototype and will obtain feedback from the partner, Ability Prosthetics, and the client to deliver a final prototype. This poster details the recent mechanical and electrical design optimizations, grip strength testing, and integration of mechanical and electrical components to build the current functioning prosthesis.
Trans World Radio - Culvert Design

Warner C. Hockenberry, Gabriel J. Tiday, Darren J. Heisey, Logan J. Horst, Seth M. Kline, Daniel O. Thomas, and J Scott Heisey

Trans World Radio (TWR) is a mission organization focused on broadcasting the Gospel around the world. TWR now serves 190 countries by transmitting in 275 languages, using radio to deliver the message to as many people as possible. The organization’s West Africa Transmitter Site in Benin currently has accessibility problems due to high streamflows and saturated ground conditions during the rainy season. The site also needs a secure perimeter to reduce trespassing and theft.

To address these issues, our client, Garth Kennedy, Director of the West Africa Transmitter Station, has asked the team to design two culverts, one at the upstream property boundary and one at the downstream boundary. Culverts are advantageous for this scenario because they can act as a bridge, while the pipe size can be restricted to inhibit trespassing. Once the culverts are built, the fence and perimeter road can be extended over them.

For both sides of the property, the team has designed a series of U-shaped, pre-cast concrete box culverts. The team calculated the design flows based on rainfall data and the topography of the site to determine the size and number of box sections. The team has also designed the culverts and the supporting concrete structures to bear the load of vehicles and the machinery on site. TWR plans to construct the pre-cast culverts on-site, and then build the supporting structures and install the culverts during their dry season.
Better Pumps: Reliable Handpump Infrastructure

Andrea Hunsberger, Joshua L. Maxson, Matt J. Caldwell, Caleb E. Danehower, Darren Kulp, Darin M. Landis, Jacob Valentine, Emma L. Workman, Tony Beers, Matthew Schwiebert, and David T. Vader

Approximately 90 million people in Africa lack access to safe drinking water, despite having water infrastructure installed in their community. The India Mark II and the Afridev handpumps are among the most widely used handpumps in the world. Sadly, studies show that approximately 30% of these handpumps are non-operational due to failures of the bearings, seals, head flange, and other common components. The Better Pumps team of the Collaboratory provides engineering support for partners who are working to improve handpump sustainability. We partnered with Tony Beers and AlignedWorks to validate a bearing test methodology for the India Mark II handpump. By modifying the loading conditions in our handpump test machine, we were able to replicate failures observed by AlignedWorks in a field trial of their bearing design. We partnered with Matt Schwiebert and Living Water International to test new seal designs for the India Mark II and Afridev handpumps and to measure head flange deflections in the India Mark II handpump. Seal performance data collected by the team was used to validate a new design in advance of field trials by Living Water International. Head flange deflection data was collected for partner benchmarking of their computational analysis. Test methodologies and results are reported.
Land Development - Tree 4 Hope

Caleb R. Light, Jorge O. Zambrano, Olivia R. Albee, Corey B. Englehart, and J Scott Heisey

The Land Development Team has partnered with Tree 4 Hope and Hope Academy in Santa Lucía Milpas Altas, Guatemala to improve the outdoor facilities of the school. Jenn and David Hope-Tringali are the client/partner representatives of the school for this project. The goal of the project is to provide design and construction drawings for three main elements of the proposed land development: (1) a parking lot for buses and school vehicles that enter the site, (2) a single sports court that can accommodate basketball and soccer, and (3) a playground that is directed towards themes associated with STEAM (science, technology, engineering, art, and math). The team has completed project drawings to allow construction by local personnel, or by student or church mission teams when travel is allowed to resume post-pandemic.
Preparing For Extended Field Tests of the Intelligent Water System

Josiah J. McCarthy, Daniel J. Labrie, Evan Freed, and Randall K. Fish

The Intelligent Water System, which improves access to clean water by autonomously monitoring and reporting on the health of hand pumps in developing countries, has been under development for several years. This development has included short-term prototype field tests in several countries. The design has matured to the point that an extended field trial to demonstrate performance and reliability has been requested by our client. In light of this, the team has implemented design changes to address issues from our most recent prototype field test and begun manufacture of the first five systems intended for installation in Burkina Faso. This poster highlights the code changes enabling more accurate determination of the volume of water pumped and the simplified mounting of the system’s Handle Motion Sensor.
A Low-Cost, Portable Fluorescence Correlation Spectrometer for Disease Diagnosis

Jessica E. Paulus, Al W. Mokris, Brittany Shirk, Nathan E. Cordell, Castine L. Donoff, Jeffrey Gao, Sam J. Gulinello, and Matthew J. Farrar

The DVD team is developing a cost-effective technique for measuring HIV load in resource-restricted regions. Our client is Dr. Phil Thuma and the Macha Research Trust in Zambia. Our design is based on advanced fluorescence spectroscopy that utilizes a fluorescence protein probe, confocal optics, and low-cost, low-power electronics to assess viral load in a patient blood sample. Our timeline for a functional exploded prototype is Fall 2021.

Specifically, we are employing a method of spectroscopy that seeks to identify individual viruses in dilute samples by characteristic “bursts” in fluorescent and elastically scattered light. We have assembled a housing for a custom-designed detector, associated electronics, and signal processing hardware. One project goal is to integrate this modular design into a single printed circuit board. Communication between signal processing hardware and a software-based user interface implemented on a Raspberry Pi and touchscreen is achieved by the use of a Serial Peripheral Interface (SPI) protocol. The entire system is battery-powered. This system will allow for fast, effective viral load determinations in remote settings.
On-Campus Solar PV Lab: Component Selection is Only the Beginning

Noah A. Rood, Jonas E. Kolb, Christian Pilawski, Garrison Shields-Seelig, and Randall K. Fish

The work of the Solar PV Team is to design and install Solar PV systems which enable our clients to fulfill their mission in the presence of unreliable or non-existent electrical power. In order to experiment with different Solar PV configurations and train new members, the Solar PV team last year designed a Solar Lab to be installed in and next to Frey 70. This work paralleled the design/component selection typically performed prior to an installation site trip. This year, the team modeled the efforts typically done at the installation site by building and configuring the Solar Lab design. This poster will focus on the lessons learned about decisions that need to be made in the field to convert a Component Selection level design into a Functioning PV System.

Force Characterization and Manufacturing of a Dynamic Unilateral Clubfoot Brace

Leigha R. Southall, Michelle Lo, Clint M. Meekins, Jacob R. Cornwell, Brittney D. Fouse, Sam J. Rasinske, Jordan M. Witt, and Tim Howell

Clubfoot is a musculoskeletal birth defect characterized by an inward twisting of an infant’s feet. Currently, a series of casts are used to correct the clubfoot, and a boots-and-bar brace is used to maintain the correction. However, this method has concerns with compliance, comfort, and social stigma. Hope Walks and their clinic in Kijabe, Kenya are interested in implementing a new maintenance brace that addresses these concerns. Mr. Jerald Cunningham, CPO, designed and is utilizing a unilateral clubfoot maintenance brace called the Cunningham Clubfoot Brace. He asserts his brace reduces treatment time, lessens social stigma, and increases child mobility. However, to date, there is not enough published research on its biomechanics and patient success rates to confirm his findings.

The Cunningham Clubfoot Brace Collaboratory project seeks to validate the effectiveness of the Cunningham design through biomedical testing and increase brace availability through sustainable manufacturing. To do this, the team is measuring the biomechanical forces applied by the brace with multiple force sensor systems and an infant foot model. The team is assisting Mr. Cunningham in his plans to use injection molding to increase brace production by scanning and creating CAD files of the brace. The team is also completing a failure and reuse analysis of the Cunningham Brace for the clinic in Kijabe. Furthermore, the ongoing clinical study at CURE International's hospital in Kijabe, Kenya, and Dr. Emily Farrar’s research paper will provide greater insight into the effectiveness of the Cunningham Brace. These collaborative efforts will allow for further understanding of the effectiveness of the Cunningham Brace and its acceptance as an alternative clubfoot maintenance brace.
A Low-Cost Egg Incubator to Provide Zambian Churches with Income and Food Security

Claudia M. Tolley, Jacob M. Barton, Aaron Bashore, Matthew D. Eells, Lydia Reber, Shekinah Ellis, Brandon Koehnke, and Philip M. Tan

Partnering with Brethren in Christ (BIC) Church in Zambia, the Egg Incubator Team is seeking to help provide a source of income for the growing churches in Choma, Zambia. They will accomplish this by designing and building a high-quality, low-cost egg incubator fabricated from local parts and cheap internationally available parts for The Nahumba Mission, in Choma, Zambia. The team’s design will provide the means for the Mission to hatch and sell chickens to provide both food security and a sustainable supplemental income. With the specifications to maintain temperature, humidity and constant ventilation, the team selected heating and humidity concepts for their incubator series. The team completed both mechanical and electrical designs for the setter and hatcher. In preparation for testing the incubator design with fertilized eggs, the team has also produced an incubation and hatching plan and achieved IACUC approval. Currently, the team is in the prototyping phase, while simultaneously monitoring the temperature and humidity in an existing incubator setter design. Once the team finishes their hatcher prototype and verifies that the temperature and humidity specifications are met, they will be ready to test designs using fertilized chicken eggs.
