Mems 411 Final Report - Plate Pourer Ii, Minsoo Ha, Patrick Champlin, Timothy Young
Mems 411 Final Report - Plate Pourer Ii, Minsoo Ha, Patrick Champlin, Timothy Young
Mechanical Engineering Design Project Class
The objective of this project is to create a machine that has the capability to pour Petri dishes. The usage of this machine must be easier than simply performing the task by hand, be automated, capable of producing 120 plates per hour, be sterile, prevent the plates from sloshing, fit in a fume hood, and stack the plates while they are cooling so that they may cool properly. This all was accomplished with a device that drops the plates vertically down, fills them, and then lowers them into storage thanks to their now increased mass and a spring-loaded platform.

Mechanical Engineering Design Project Class
The 2015 ASME Challenge was to construct a device which manufactures a projectile from a piece of copy paper then launches it as far as possible. At the competition, each team has five minutes to assemble their machine, craft three projectiles and fire them for a cumulative distance. In addition to launching paper projectiles as far as possible, the machines must also be designed to take up as little space as possible while still performing its main function effectively. A team’s final score is the ratio of the cumulative distance of all three projectiles to the volume of a box …

Mechanical Engineering Design Project Class
The goal of this project was to build a cost-effective automated system that can handle the process of pouring agar into plates, but is also easily sterilized and operates with no supervision. This agar plate-pouring machine is intended to increase productivity in small-scale biology and research labs by pouring at least 120 plates per hour while keeping the agar sterile and preventing contamination. This was accomplished with a multi-valve system controlled by an Arduino board which could also fit inside of a fume hood.

Human Powered Ice Resurfacing Machine, Nicholas Furman, Kameryn Truman, Meagan Leonard
Mechanical Engineering Design Project Class
The purpose of this project was to design and build an ice-resurfacing machine that was entirely human powered so it could be used safely on outdoor rinks and prevent harmful emissions indoors. This required analysis of several different mechanical systems and many different attempts to produce a working prototype. The prototype reduces the amount of water used when compared to a current ice-resurfacing machine by recycling snow from the ice. The sources of risk were determined, analyzed and solved throughout the project.

Designing A High-Lift Performance Wingsuit, Kimon Stephanopoulos, Ben Levy, Ignacio Rabadan Jr.
Mechanical Engineering Design Project Class
Many current wingsuits are at their aerodynamic limit due to poor performance from the fabric that makes them up. We propose to evaluate the benefit of adding a rigid wing to the wingsuit, using rapid prototyping in a 3D printer and non-dimensional wind tunnel analysis.

From Quadcopter To Submarine, Everett C. Brown Ii, Juan Matheus, Sam Gardner
Mechanical Engineering Design Project Class
The goal of this project was to create a quadcopter that is capable of going underwater and returning to the surface to take off again. This concept was created after speaking with a customer that had very specific user needs. The project included creating several different designs and doing a concept selection based on these user needs. After selecting a concept, a design was created and adjusted based on an engineering analysis. The parts were selected based on a budget that was assigned to the project and a prototype was created. The final prototype was capable of flight and was …

Mechanical Engineering Design Project Class
This project, Plate Pouring III, is an automated device that fills petri dishes with a liquid solution called Agar. This is done in a sterile environment, not needing any human interaction for the mechanism to function. It safely removes the lid individually from petri dishes, injects the solution, reinserts the lid, and stacks the filled petri dishes.

Mems 411 Design Report - Modular "Do-It-All" Drone, Nicholas Okafor, Jordi Turner, David Brablec, Ike Witte
Mechanical Engineering Design Project Class
The main objective of this senior design project is to design and build a capability that allows different attachments (i.e. camera, flashlight, speakers, hook) to be attached and detached electromechanically from a drone. The main challenge in this project was our cost constraints. Weight is one of the most important constraints in aerial vehicles, and with a small budget, it was very challenging to find a powerful drone and manufacture light and durable parts. The modular system involved two general components: a drone retrofit and the attachments. The drone needed to be retrofitted to house additional electronics (i.e. Arduino, remote …

Mechanical Engineering Design Project Class
Dr. Kirk Quigless has designed the Golden Bite™ athletic mouth guard to properly align the jaw. Literature suggests that the proper alignment of the jaw will provide users with increased performance gains. Accurately determining these gains without bias is a difficult task. Dr. Kirk Quigless needs to quantify the performance gains from his mouth guard. The portable device designed in the Golden Bite™ Mouth Guard Project will record the force exerted by an individual over a period of time. From this data, Dr. Kirk Quigless can determine the change in force output from individuals with and without the mouth guard, …

Saran Wrap 2: Clip Handling Device, Alex Arteaga, Brian Lockwood, Cameron Adams
Mechanical Engineering Design Project Class
The common household Saran Wrap has been in production since 1933. A common problem comes in the handling of the plastic sheet after being torn from the roll. Corners frequently fold on themselves, the sheet bunches up, and renders some pieces useless. Our objective was to create a device along with a system to eliminate these problems, without compromising the simplicity and speed of the original box cutter.

Plate Pouring Iv, Alexander F. Kwakye, Carey D. Haefele, Arjay Parhar
Mechanical Engineering Design Project Class
From a high school biology class to a small research facility, this machine will cheaply (relative to its competitors) automatically pour a layer of agar into a large number of Petri dishes in order to grow bacteria micro-cultures. Designed to be powered within a fume hood, the user simply needs to open up the containment facility, insert stacks of Petri dishes, and pour in a batch of premade agar. Within the hour, approximately 120 Petri dishes should be layered and ready for further experimentation.

Mechanical Engineering Design Project Class
The American Society of Mechanical Engineers has challenged us to create a machine that forms a projectile from a single sheet of paper, and then launches that projectile. The success of the device will be measured by how far the projectile is effectively propelled, how straight the projectile is propelled, and how much volume the device takes up when packaged.

1.1 The objective of this senior design project was to design and build an aerial drone with a landing gear system that would allow leveling and take off from a sloped terrain. The drone should be able to level on a slope with a maximum incline of 20 degrees and the leveling process should not exceed 30 seconds. In addition, the leveling system must be automatic and deployed using the flight controller.

Mechanical Engineering Design Project Class
Our design problem was to create a solar radiation tracking device. The primary goal of this device was to keep a solar panel perpendicular to the solar radiation with 95% efficiency throughout the day. The tracker had to be able to account for the sun’s seasonal angle in St. Louis, and the design would be even better if it could account for the sun’s seasonal angle at any latitude. Another important aspect of the solar tracker design was that it must be able to reset itself each day for the sunrise without human input. Other aspects to consider were weatherproofing …

Treadle Driven Lathe, Eleanor B. Mullard, Daniel Kronthal, Aaron Cohn, Robert Borovsky
Mechanical Engineering Design Project Class
The main objective of this senior design project was to design and build a treadle-driven, metal-cutting lathe that has the ability to cut 3/4" diameter material and produce small parts up to 3" long. The main challenge in this project was to successfully generate enough power through the treadle driven system to successfully cut metal at the proper specifications, while simultaneously meeting all of the user-needs. The entire system needed to be operated and pedaled by a single person, which put constraints on the location of the treadle relative to the lathe itself so the user could comfortably operate both …
