Senior Design Competition
As the capstone of Penn’s practice-integrated mechanical engineering curriculum, the two-semester senior design sequence challenges students to bring theory, skills, general knowledge, and inventive energy to bear on substantial engineering problems. There is no “typical” project and the variety is always surprising: some projects lead to marketable products; some explore a theoretical principle; some are just for fun. But taken together, they reflect the breadth and diversity of mechanical engineering.
Team Posterra, comprised of Chris Fox, Hanna Kim, Mona Lee, Rakesh Ravi, Seth Rogers, and Lucille Stinn, were winners of the of the Judges’ Choice Award for excellence based on the discretion of the judges.
Posterra is a handheld underwater device that aims to be the ultimate assistant to SCUBA divers participating in clean-up dives. It accomplishes this goal by allowing divers to safely remove solid waste at depths up to 10 meters within the sublittoral zone of the ocean, while also providing an effective storage solution for the collected waste. The device, designed and manufactured by the team, functions using a venturi pump that interfaces with a hose and mesh containment unit attached to the diver’s air tank. Once the diver is underwater, the device’s suction force can easily be turned on and off by flipping a single switch. The venturi pump directs the waste through the hose into the containment unit on the back of the SCUBA diver without threatening the diver’s safety and maintaining the necessary degrees of freedom required during swimming. An additional quick release mechanism allows the diver to quickly remove the entire device in the event of an emergency by removing a pin on the back of the SCUBA tank. Currently, there are no commercially available devices that provide aid during the process of clean-up dives. Existing technology only targets solid waste within the top 1-2 meters of the water column. The team has designed and built the device to operate in the conditions of underwater clean up dives while prioritizing diver safety and mobility. A prototype has been robustly tested within a submerged environment to ensure maximum waterproofing and suction capabilities.
Team PVRE, comprised of Nicholas Genovese, Andreana Izotov, Nelson Ngouenet, Paul Owens, and Andres Voyer, were winners of the William K. Gemmill Memorial Prize for outstanding creativity.
Water borne illnesses are a great health risk across the globe. Roughly 2.5 billion people still do not have access to safe water sanitation and over 3.5 million people die each year from water-related disease. These deaths are more prevalent in developing nations, where inadequate water purification is unable to eliminate bacteria from the water supply. Team PVRE’s goal is to create a cost-efficient, low-maintenance device that allows countries to have accessible and easy methods of water purification for implementation in local water storage locations. Ghana is a developing nation that suffers from a dangerously high quantity of water borne illnesses, with 25% of all child deaths under the age of 5 due to diarrhea, and 80% of all diseases caused by unsafe water. Based on discussions with stakeholders in Ghana, Team PVRE has a better understanding of the needs of the community. Team PVRE has designed a self-sustaining, long term, low maintenance water purification and filtration system to implement at the exit of communal storage tanks in developing communities. Their system relies on solar generated energy which is stored in a battery and used to power an ultraviolet germicidal lamp. The water is filtered through a sediment spindown filter and passes through a chamber that contains the ultraviolet light, deactivating any bacteria or protozoa within the water. This project will culminate in sending the PVRE system to Kumasi, Ghana, where it will be implemented to provide clean drinking water.
Team BEND, comprised of Kelly Babitz, David Bunn, Kathie Jin, Lilian Stoesser, and Christopher Valencia, were winners of the Francis G. Tatnall Prize for an outstanding project showing ingenuity, proficiency and usefulness.
Makers and engineers often integrate bent sheet metal parts into their designs to achieve complex geometry without excessive material removal. Yet, small shops and educational spaces often lack the tools to help engineers create cheap, accurate parts. BEND is a precise, reliable, compact, and low-cost sheet metal bending machine, suited for the needs of academia and makerspaces. A hydraulically actuated system, this machine allows users to bend aluminum and steel sheet metal up to 12” in bend length and at thicknesses up to 0.25”. Users would line up their sheet metal using the manual backstop positioning system and actuate an electric pump to create their parts using air bending tooling. BEND also comes with a lookup table to aid the user in accounting for spring back in their bends, resulting in accurate and predictable results. Total time to complete a bend is less than 1 minute, about 6 times faster than manual tools. Final items produced on BEND have tolerances of +/- 2° on bend angle, and +/- 0.050” on bend location. Due to high loads in the system, all components were designed with safety factors and analyzed using FEA to ensure reliability and safety. The team conducted extensive safety tests to verify these calculations before proceeding into validation tests for locational and angular accuracy and material thickness feasibility. BEND allows students and makers to produce custom made sheet metal parts with angular and locational tolerances comparable to industry standards, with only a fraction of the cost and time.
Team ReActive, comprised of Alice Bian, Jack Lanzi, Madison Magee, Jimmy Ni, Mustafa Shabazz, and Huen-Yee Tso, were winners of the John Couloucoundis Prize for the best senior design presentation.
Despite dramatic strides in gait and balance clinic technologies, only 35% of physical therapy patients fully adhere to their plans of care when home. Patients struggle with a lack of positive feedback, recalling instructions from their therapist, and brace discomfort during extended wear. The core of ReActive R1 is a Digital Light Synthesis 3D printed leg brace which seamlessly integrates three inertial measurement units and associated electronics. Using 3D printing, ReActive R1 is able to provide a custom brace while going directly from clinician measurements to CAD – skipping the cost and time associated with leg casting. These custom braces, keeping brace junctures within 2” of joints, have been shown to improve walking results. Measurement protocol and design has been validated to minimize brace slippage, the major source of patient discomfort. Through fall testing and finite element analysis, ReActive R1 is designed to survive everyday impacts. ReActive R1’s sensors provide ankle and knee flexion within 3° of markerless motion capture, the leading standard in gait mapping research. These data are compiled into the ReActive App, which provides patients a portal to communicate with their physical therapist and track their progress. With all day battery power, users can charge ReActive R1 overnight for easy integration with their current habits. The ReActive R1 brace brings a revolution to remote rehabilitation with gait insights powered by a custom KAFO brace.
Team MARV, comprised of Gabriel Blanchard, Adarsh Kulkarni, Samantha Lunt, Sarah Pasquale, and Madeline Rice, were winners of the Francis G. Tatnall Prize for an outstanding project showing ingenuity, proficiency and usefulness.
NASA is planning to land the first woman and next man on the Moon by 2024. The goal of the program is to achieve a long-term presence on the Moon, establish a moon economy, and provide a stepping-stone to send humans to Mars. Launching humans into space continues to be a risky endeavor and safety systems are paramount. In the event of a rocket failure during launch, the crew capsule will jettison from the main rocket and land in the ocean. The crew must then board an inflatable lifeboat. There is risk that a crew member is separated from the main group during this disembarkment. The Maritime Autonomous Rescue Vehicle (MARV) is an autonomous watercraft that may be used to accurately locate the stranded crewmember and provide them with water, first aid supplies, and communication equipment while search and rescue first attend to the crew on the lifeboat. MARV was designed with a catamaran hull for stability and payload capacity and can autonomously navigate safely within reach of the stranded astronaut. The system achieves autonomous navigation using three redundant and progressively more accurate sensing techniques. As NASA intends to drop MARV from the air, the team designed the craft to operate under any landing orientation, survive up to a 15-foot fall, and demonstrate water-tightness when encountering significant impact forces.
Team SAFFIRE, comprised of Arjun Dave, Brian Chirikjian, Chris Stanczak, Matthew Fohner, and Pranav Garg, were winners of the William K. Gemmill Memorial Prize for outstanding creativity.
Saffron is used as a spice and colorant in many popular culinary dishes, cosmetics, and perfumes. At $5000 per kilogram, it is the most expensive spice in the world! This cost is a result of its labor-intensive production process. The source of the spice is the three small stigma of each saffron flower, which are currently plucked by hand. The process requires almost 200 person-hours per kilogram of spice. Domestic production of the spice would provide an important rotational and cash crop for farmers, but the high cost of human labor in the United States is prohibitive. SAFFIRE was designed to lower the cost of processing. Saffron flowers that have been cut in the field are placed into the machine. A vibrating array of troughs aligns the flowers, the petals of the flowers and stigma are cut from the stems, and then the mixture is sorted using a blower and conveyer system. The SAFFIRE system was designed to yield a 95% stigma recovery rate to enable profitable domestic saffron production.
Team Crampr Dampr, comprised of Folatomi Alli-Balogun, Malini Rao, Vlasta Schutzenhofer, Abigail Szabo, Audrey Walsh, and Xinyue Wei, were winners of the John Couloucoundis Prize for the best senior design presentation.
Menstrual pain, caused by contractions of the uterus during monthly menstruation, affects roughly 50% of people who menstruate. 10% report pain so severe that they are unable to carry out normal daily activities. Common forms of pain management such as nonsteroidal anti-inflammatory drugs, heating, massage, and exercise come with limitations due to health restrictions, cost, and conflict with everyday routines. Crampr Dampr is a discreet device (only 1.25 inches thick) that the user wears around their abdomen like a belt and provides both heat and massage. Unlike existing heating pads and massage devices that are bulky and need to be plugged into a receptacle, Crampr Dampr is diminutive enough be worn unnoticeable under clothing and provides freedom of movement via a rechargeable battery source. Silicone-coated nichrome wires distribute the heat across the abdomen and a quiet pump and custom air bladder system produces massage-like pressures. The team performed research on over 100 users to determine efficacious and safe temperature and pressure envelopes. The team also prioritized the safety and comfort of the design. Crampr Dampr employs a quick release system in case of malfunction and engineered fabrics were integrated to wick moisture away from the wearer’s skin.
Team Aqualus, comprised of Phoebe Altenhofen, Joseph Auckley, Leora Korn, Andrew Levine, and Caroline Weiss, were winners of the Judges’ Choice Award for excellence based on the discretion of the judges.
Microplastics, plastic particles with sizes less than 5 millimeters, have been detected across the world’s waterways. This pollution poses a serious threat to marine life and aquatic ecosystems. Informed and impactful policy can mitigate the hazards of these pollutants providing a robust understanding of their magnitude and dispersion. Current microplastics sampling methods are inefficient and imprecise – they rely on labor intensive practices that yield error prone and incomparable data sets. Enter Aqualus! This boat-mounted microplastics collection device processes massive amounts of water (up to 500 liters per sample) through a stack of filters to isolate microplastics ranging in size from 10 to 500 microns. The solution features a hose, reel, and pump system to allow collection of samples up to depths of 50 feet. Moreover, the system is semiautonomous and low-cost. Aqualus provides researchers with an efficient, accessible, and accurate method to track the health of our aquatic ecosystems.
Team Aerate, comprised of Spencer Collins, Jake Fine, Ashwin Kishen, Yann Pfitzer, Connor Sendel, and Sam Weintraub, were winners of the Francis G. Tatnall Prize for an outstanding project showing ingenuity, proficiency and usefulness.
The number of air conditioners is expected to triple by 2050, which will result in unsustainable demands on the energy grid and even more perilous carbon dioxide emissions. The majority of this growth will occur in humid regions that are unsuitable for existing, highly efficient evaporation-based air conditioners. To address this problem, the team developed a 2/3 scale evaporative air conditioner that utilizes nascent and efficient membrane dehumidification on the input stream and evaporative cooling on the output stream. The development of the Aerate system required a deep understanding of heat and mass transfer, detailed characterization of dehumidification membrane performance characteristics, vacuum pump analysis, advanced manufacturing, and a series of increasingly capable prototypes.
Team TerraNova, comprised of Jonah Arnheim, Claire Brundage, Allison Grey, Dylan Hawkes, Gregory Robinov, and Raphael Van Hoffelen, were winners of the William K. Gemmill Memorial Prize for outstanding creativity.
Tunnels on the Moon may provide insight into its geologic history, access to valuable minerals, and safe harbor for long-term missions. Skylights above these tunnels, the result of tunnel roof collapses, provide a means of entry. However, traditional wheeled rovers would get stuck in these rubble-filled entryways. To address this problem, the team devised and manufactured the TerraNova rover, which features a novel cam and follower jumping mechanism to surmount these obstacles. The team performed aggressive strength and weight analysis of the system’s structural components in order to deliver a robot capable of traversing difficult terrain while carrying impactful sensor systems deep into lunar tunnels.
Team SharpShooter, comprised of Bennet Caraher, Paul Flores, Karina Gunadi, Miltos Kitsios, Matt Oslin, and Jake Welde, were winners of the John Couloucoundis Prize for the best senior design presentation.
Photographers today often use long shutter speeds to take high dynamic range, low light, or high depth of field pictures. Camera movement during these shots leads to unsuitable image blur. Currently, long-exposure photographs require the use of bulky equipment such as tripods and gimbals. The significant setup time required for these devices often leads to lost photographic opportunities. SharpShooter is a compact, portable camera accessory that can be attached to any conventional camera and provides stability approaching that of a tripod – all with near-zero setup time. The system utilizes reaction wheels, much like those used to change the attitude of satellites, to counteract external disturbances and provide crisp long-exposure images. The development of SharpShooter required significant stakeholder testing, a deep understanding of the mathematics behind image sharpness, thermal analysis, a lightning-fast control algorithm, and design for assembly.
Team S.S. MAPR, comprised of Sherry (Xiaoyi) Chen, Frank (Fangyi) Fan, Quinn Wu, Eunice Lee, Vanessa Howell, and Mia Mansour, were winners of the Judges’ Choice Award for excellence based on the discretion of the judges.
River ecosystems, which are often a source of drinking water, are constantly threatened by the discharge of harmful substances from industry and farming. Current water quality monitoring methods require significant labor costs and capital investment, which leads to infrequent and low-resolution measurements. Water authorities need a method to efficiently and economically track water quality across rivers and at multiple depths. Enter S.S. MAPR! S.S. MAPR is a low cost (approx. $3000) watercraft that is capable of collecting water samples and performing in situ water quality measurements to a 50-foot depth. The system is easily transported by one to two persons and collects measurements autonomously at waypoints specified by the user. The system promises to shorten the time between data collection from 1 year to 6 days while reducing operating costs by up to 80%.

SeaSeacher is an autonomous, reverse-bow catamaran for coral reef data collection. Coral reefs have a large economic impact on coastal communities and existing coral reef data collection is unnecessarily time consuming and expensive. Working in conjunction with ecologists, team SeaSearcher devised a highly portable and stable vessel that can be remotely instructed to map a coral reef with 50 cm accuracy and cover an area of 40,000 square meters within a 6-hour time period. The project required a deep understanding of fluids, system dynamics, controls, and electronics.
Team Daedalus, comprised of Rome Arnold, Eugenia Bejar, Pele Collins, Max Newberger, Michael Pearson, and Rosalind Shinkle, were winners of the William K. Gemmill Memorial Prize for outstanding creativity.
Currently, space vehicle recovery parachutes open in discrete stages (disreefing stages). These discrete stages result in large peak impulse forces that require overdesigned and costly vehicle support structures. Working in conjunction with SpaceX and NASA engineers, team Daedalus devised a novel disreefing system that utilizes a passive capstan device and active friction brake system to continuously control the disreefing process. Ultimately, the device promises to reduce vehicle launch costs by lowering peak impulse forces during vehicle descent. The development of the Daedalus system required an intricate understanding of strength of materials, controls, and friction.

Their project is entitled StoRC: Search to Rescue Craft. Unmanned aerial vehicles (UAVs) provide a way for taking pilots out of harm’s way during dangerous missions, either from weather or military threats. StoRC explores the application of autonomous flight and payload delivery on a model airplane. The system presented uses a UAV to deliver supplies to a target location via a parachute. The UAV’s guidance system uses GPS technology to autonomously navigate to a target location. Once on target, the system would combine data from its sensor package with a drop trajectory model to calculate a release point for its payload. After releasing its payload, the UAV would then autonomously flies back to its home base for human-controlled landing. Models of the UAV’s physical dynamics and the autonomous control scheme were created and used to develop initial parameters for the control code. By performing test flights and logging flight data, these models were validated and were used to build more complex autonomous behaviors. Stabilized flight, autonomous drop trajectory calculations with payload release, and autonomous navigation methods were all implemented and successfully tested, though full start to finish missions are still pending.
