Universal Weight Machine, Oscar Andrade, Bibiana Koch, Robert Molloy, Haley Rentfro, Emily Woods

Mechanical Engineering

The purpose of this project is to design and build an inexpensive, universally accessible multi-station exercise machine for the physical and mental well-being of athletes of the Special Olympics and Pathpoint Life Education & Advancement Program. The machine has three sides tiered to higher resistance: the first station offers a minimal resistance aerobic exercise focused on moving the arms with an ergometer, the second station provides numerous locations to latch on resistance bands that will build strength in the athlete’s arms and chest, and the final station has a donated weight machine that offers lat pulldowns and flys with maximum …

Automated Bearing Press, David Baker, David Brock, Engelbert Diec

Mechanical Engineering

Our group was presented with a challenge to design an automated machine to replace Micro-Vu’s current manual pressing operation. We moved, planned, and scheduled our tasks for the three quarters we will be working on this project by using a Gantt chart. In designing the machine, we generated concepts and used analysis and prototyping to select the most promising ones. Our final design uses a pneumatic press to press the parts, and it includes magazines to hold the parts before pressing, pneumatic actuators to move the parts to and from the pressing location, and a lever to separate the defective …

Testing Feasibility Of Inductive Power Coupling For Modern Applications, Andrew Burman

BioResource and Agricultural Engineering

This project takes two bifilar tesla coils and uses them to find a % efficiency of power transfer as distances between the coils decrease. The reason this experiment is being conducted is to find possible implications for wireless charging of vehicles using similar style coils. This project conducted experiments on 60 Hz, 400 Hz, and 1 kHz frequencies for a small input signal. The general conclusion is that as the frequency increases more power can be transferred and higher efficiency of power transfer is seen. This project also concluded that it could be possible to get higher efficiency at a …

Design And Implementation Of A Three Dimensional Printer Using A Cylindrical Printing Process, Brandon Hoy

Electrical Engineering

Many 3D printers utilize a Cartesian (XYZ) printing process. Implementing a polar coordinate printer providing a faster printing method and introduces new printing algorithms, increasing printing efficiency. This cylindrical 3D printer applies a circular-moving baseplate and a heating printer head (extruder) moving radially and vertically. A processor accepts pre-processed polar data points and transpose the appropriate programmed printing commands to the motors units. The extruder also has a control loop, keeping the temperature inside the desired range. This prototype prints using polylactic acid (PLA) filament. Additionally, a display screen updates every second the: printing time, extruder temperature, and status notifications.

Rapid Battery Exchange (Rbx), Daniel Rostom

Electrical Engineering

Electric vehicles have begun to hit the main stream market, with sales raising form under 20,000 in 2001 to over 110,000 per year since 2014 [1]. With new models hitting the market every year, and more people becoming conscious about their fossil fuel usage, this trend will only continue until there are more electric vehicles than combustion vehicles on the road. A major drawback of electric vehicles is their limited range, and relatively long recharge times. Even with advancements in battery charging speed, such as the Tesla super charger, able to provide up to 90 miles of range in just …

Automatic Water Pump Controller, Alam D. Salguero, Kyle Russell Marquez Weeks

Electrical Engineering

In countries including Indonesia, Mexico, Guatemala, and El Salvador, a city water authority supplies the clean water and pumps it into large ground-level storage tanks. A resident’s water pump then pumps the water to a water tank on top of his/her house. When the water level in the ground-level storage tank becomes too low, the pump siphons air and shuts down, requiring a resident to manually prime the water pump to get it running again. Residents struggle to monitor the water level of the tanks effectively and keep the pump running properly. To remedy the issue, the Automatic Water Pump …

Active Charge Balancing For Cardiac Stimulation, Maci Miri

Electrical Engineering

Worldwide, there are about 3 million people who have pacemakers, with 10,000 new implantations of ICD’s each month. [heart.org] Due to the gravity and importance of the function that ICD’s provide, these devices must be extremely reliable and highly effective. However, because of the high tolerances of IC manufacturing, stimulation circuits for pacemakers may be slightly unmatched and over time, may have a net DC charge applied to the tissues in the heart. Extra charge pumped into body tissues is dangerous for the patient’s health; the pH of the tissue can be raised and corrosion of the stimulating electrodes may …

A Stroke Therapy Brace Design, Evan Kirkbride

Electrical Engineering

Victims of stroke often have difficulty with rehabilitation. With limited movement on their affected arm, patients often do not want to move much for physical therapy. In this project, we design a robotic brace that helps stroke patients move their arm more effectively in a reaching or pulling motion. By giving patients more movement in their affected arm than they would have otherwise, patients gain more from rehabilitation. The brace also adapts to the patient’s needs, providing more inclination or resistance as needed for their physical therapy. This kind of therapy engages patients rather than relying on their likely dwindled …

Car Safe, David Van Workum

Electrical Engineering

The Car Safe project helps protect parents and caretakers from the dangers associated with leaving children in hot vehicles. The device supports parents through notifying them of the child’s wellbeing and status while within an automobile. Specifically, the device monitors the child’s ergonomic experience and the spatial proximity between the caretaker and child. Car Safe utilizes this information and determines if the child finds himself in a dangerous environment. Due to its compact design, the device functions independently of a specific car seat design, allowing customers to integrate Car Safe in the car seat environment of their choosing.

Led Slackline, Kristina Forystek

Electrical Engineering

A Slackline is a nylon rope that uses tension to suspend itself above ground. Slacklines are usually tied between two trees while the user walks across the line. Slacklining provides a daytime activity as user vision weakens after the sun goes down. A LED slackline allows users to practice tight roping at night. The lights let the user know when they perform well. The slackline uses a three axis system to determine how much the user moves. The slackline senses how much the user shakes in three dimensions and then relays it back to the LEDs. If the user shakes …

Tilt-Rotor Drone, Benjamin Stone, Zachary Crandall

Electrical Engineering

A drone is defined a "an unmanned aircraft that can fly autonomously[2]." In the year 2016, there exist many applications for small scale drones. Drones, having had primarily military applications, now have use in hobby robotics, photography, and even in surveying. But drones have not yet been perfected and still have room for much improvement. Several problems with drones come in the form of battery life, stability, and size. Large drones can fit many sensors and probes, but are heavy and have less flight time. For autonomous drones, stability can be an issue even though there exist many stable drones. …
