Inmate Vital Signs Bracelet Monitor

bracelet monitorThe project we were assigned was an inmate vital signs bracelet monitor. Our goal was to be able to produce a bracelet monitor that is equipped with the ability to track and record vitals and location, along with monitoring that feedback on a single device. Although it is impossible to prevent these things from happening the idea is to decrease response time when possibly fatal incidents occur so that there is a greater chance of stopping them before it is too late. The plan was to create a locking mechanism similar to that of a handcuff. The band itself will have to be made out of very durable and strong material, while still being flexible and comfortable enough to wear around the wrist.

Wheelchair for Ice Fishing

modified scooterThe objective of this project is to modify a mobility scooter so that it can be used for various outdoor activities, mainly ice fishing. The scooter that was generously donated by The Ability Center of Greater Toledo is the Rascal 130 model, which is a three-wheeled mobility scooter with an electric seat lift. This scooter is being modified to assist a local resident of Adrian, Michigan, Gloria Miller, who has recently suffered a stroke and is unable to partake in the outdoor activities that she used to. As a result, the scooter will be required to traverse harsh terrain including ice, snow, and uneven surfaces. The client also had several requests as well including a canopy for protection from the elements, a fishing pole holder, and cup holder to make the scooter more user-friendly. During the initial dynamic field tests on the ice at the Ottawa Park Ice Rink, the scooter’s start and stop ability was adequate, but its maneuverability was not acceptable. The group determined that three large-diameter, all weather tires would be the most practical solution that would align with our budget of $500. The main priority for the project was then to modify the underbody of the scooter to accommodate for the larger diameter tires. This includes the design, fabrication, and testing of an adapter, new rear wheel hubs, and a modified front tire bracket. The next priority was to order and assemble a canopy and cover for the scooter that will adequately protect our client from the rain, snow, or harsh winds.

Historic Pratt & Whitney R-4360 Aircraft Engine

group members with projectThe Pratt & Whitney R-4360 “Wasp Major” has been an ongoing project in senior design, with completed work spanning multiple semesters.  The goal for this semester was to continue restoration of the engine and complete design related tasks associated with the project. 

The Pratt & Whitney R-4360 Wasp Major was introduced and mass-produced in the mid-1940s to mid-1950s in the United States. This radial engine has 28 cylinders (4 rings of 7) and is the largest piston displacement engine to be mass produced in the US. The R-4360 which is currently being restored at the University of Toledo originally belonged to a C-119 Flying Boxcar at the New England Air Museum.  In 1979, A tornado struck the museum and destroyed the aircraft along with others.  In the early 1980s, Kevin Cameron acquired the engine and later donated it to Dr. Hixon at the University of Toledo. The engine has become a restoration project for multiple senior design groups. For this semester, our task was to lift the seven remaining cylinders in order to free the crankshaft of the engine. This process involves removing all the nuts surrounding the cylinder heads and lifting them with hydraulic fluid, one at a time. After successfully lifting every cylinder, we soon found out that there had been moisture trapped inside the engine.  This moisture has lead to the formation of rust inside the cylinders and pistons themselves.  Once the rust is removed, the cylinders are honed or replaced, and the main bearings are oiled, the crankshaft should be able to rotate freely.

Plastic Film Disposal Appliance for Ocean Plastic Reduction

group members with plastic film disposal applianceThe objective of this project was to research, design, modify, test, and evaluate improvements to an existing home appliance that recycles plastic film.  Plastic film waste is a large issue, with more than one-hundred thousand marine animals being killed each year due to plastic film waste entering oceans and waterways.  Almost all households utilize the most common form of plastic film on a weekly basis: the plastic grocery bag.  The goal of this home appliance improvement was to reduce cycle time and improve ergonomics.  The device, “Puck-It,” was created by a previous senior design group to meltdown and fuse plastic bags together.  The device succeeded with fusing the plastic bags into an easily recyclable puck, however, it had some obvious drawbacks.  The cycle time was slow, taking around an hour to make one plastic puck.  Only two bags could get melted down and fused into a puck, which leads to very low throughput and efficiency.  The handle and compacting apparatus were also awkward and not user-friendly.  The project goal was to increase the throughput of the device, reduce the cycle time, and increase user-friendliness.

Hospital Head Restraint for Stroke Patients

head restraintsDuring surgery, stroke patients are brought into an operating room to quickly remove a clot from their brain. During this procedure, the patient is awake as a scope is inserted near the groin. Due to the nature of this surgery, the head must be restrained to provide a clear x-ray picture. The Omega head restraint combines engineering functionality with artistic design. With a slide-on design that fits Toledo hospital’s operating table, the base piece of Omega is quick and easy to set up for nurses. It provides a solid, U-shaped barrier that prevents side-to-side movement of the patient’s head, and a soft cushioned base to keep the patient comfortable during the surgery. Padding is also added around the patient’s head to provide a snug fit. A Velcro forehead strap is added to prohibit vertical movement, and an optional chin strap may be utilized in special cases to further prevent movement.

Soft Robotics grasper 

grasperSoft robotics is an area of robotics in which robotic actuators are made of soft, compliant materials. Because of their high flexibility, soft robotic actuators can replicate biological movements that are difficult for a typical robot to perform. A proof-of-concept project was developed to test different 3D printable materials that could possibly be used for soft robotics. To accomplish this, our team created a functional, 3D printable pneumatic grasper design than compared the performances of our design printed in different flexible materials. The results of the materials’ performances were tabulated in a matrix that offers insight into choosing the best material and printer properties for the needs of future soft robotics applications.

Design, Build and Testing of a 10-foot door

building doorOur team was tasked with designing, testing, and building a 10-foot door. More specifically, we needed to determine what modifications needed to be made to the structural components of a fiberglass door do ensure adequate performance if the door was increased to 10’ x 5’. This project was done in tandem with Therma – Tru, a locally headquartered company that specializes in fiberglass doors. At this time Therma – Tru does not have the capability to build or test a full-scale 10-foot door. We simulated a 10-foot door by lowering the handle and lock on a standard door to approximately 8” above the bottom of the door. Doing this simulated the length of stile above the lock that a 10 food door would have.

Five doors were built (3 standard doors, 2 modified doors) and were tested using differential pressure and the deflection in the top former of the door, above the lock, was measured. Using the data from these tests we were able to develop a relation equation that would allow Therma – Tru to set either the thickness or width of the structural rail and the equation would give them the minimum other dimension needed for adequate performance.

Compost Processing Study for Zero-waste Athletic Events

Sullivan Athletic ComplexOur group was tasked with performing a research study on Savage Arena, and its current waste streams and athletic processes, and designing a zero waste process that diverts 90% of this waste stream from the landfill. A variety of recommendations and improvements can be made on the existing facility and processes as a result of our waste audits of Savage Arena’s main concourse level, where a majority of the solid waste is produced during events. Along with this research data, we were also tasked with providing a range of alternative product options for UT to adopt zero waste processes. Through these alternative options and existing facility recommendations, UT will be able to perform a research study of their own on Savage Arena using our recommendations. What is successful among these recommendations can be upscaled to other facilities on campus and accelerate UT to become a zero solid waste campus.

Lexan Bender

lexan benderMotion Controls Robotics Inc. is a custom robotic system builder who provides robotic solutions all over the world. Due to their diverse product line, MCRI regularly needs to produce unique guarding for each of their systems. To accomplish this, MCRI uses Lexan, a clear polycarbonate (similar to plexiglass) due to its high strength. It is very common for MCRI to need to apply bends to the Lexan in order to provide optimal guarding for their systems. MCRI’s current method for bending Lexan is not efficient, operator friendly or safe and takes more time than they would like it to.

This is where our team comes in. Our goal was to create a mobile workstation that was safe, and operator friendly. Our system had to and does provide a better-quality bend than the current method and in a fraction of the time. The Lexan Bending Workstation heats the material in a covered heater from both the top and the bottom, allowing for even heating. Then the material is moved out of the heater, to the bender where it is pinned by a rotary clamp. After clamping the bending arm is raised and performs a sharp corner bend of high quality. All of this can be done by a single operator. As of 5/1/2019, the Lexan Bending Workstation has been delivered and integrated into MCRI’s production system. After demonstrations and operator tutorials MCRI has stressed that they are very pleased with the outcome of this project and are looking to work with the University of Toledo in the future.

Rocket-SAT1: Deployment and Orientation Mechanism for Small Satellites

small satellite mechanismThe goal of this student challenge is to employ shape memory alloys in the design and demonstration of a deployment and orientation mechanism for a 3U CubeSat (10x10x30cm microsatellite). The deployment mechanism will be used to deploy one or more solar panels, while the orientation mechanism will be used to orient the panels to maximize power collection. The deployment mechanism will be an active system (feedback controlled), while the orientation mechanism will be a passive system.  Both designs require the use of shape memory alloys in order to satisfy the weight and volume specifications. This project is part of an international collegiate competition hosted by academic, government and industrial members of the Consortium for the Advancement of Shape Memory Alloy Research and Technology (CASMART).
