For my 4th-year captsone project at Queen's, I'm working with 4 other Mechanical Engineering students to design a passive exoskeleton that reduces the energy cost of walking. Based on the proposed design, a reduction in mechanical energy cost of 8% is estimated. Current next steps include the creation of a prototype and the conducting of both mechanical and metabolic cost testing.
Machine learning was used to categorize walking, backwards walking, jogging, and skipping using data collected from an iPhone accelerometer and gyroscope. An accuracy of 100% was achieved during testing.
In this project, I worked with another biomechanical engineering student and three occupational therapy (OT) students to create a customized ileostomy bag for a client with severe vision impairment. Because the client could not see the ilesostomy bag, she had trouble aligning it properly with the stoma, resulting in unwanted leaking of fluid. IDDOV process was used to acheive six sigma, and the satisfaction of the client. Our solution was to add a medical-grade putty to the backside of the bag, where the stoma is inserted. Becuase the putty was flexible, it created a seal around the stoma, and prevented the leaking of intestinal fluid. It also required less precision than a standard ileostomy bag, so the clients declining vision was less impactful.
In this project, I worked with 3 other mechanical engineering students to design a gearbox that optimized speed and towing power. After the design phase, a 3D printer was used to print the gearbox housing, shafts, and gears. As part of the "MECH 323 - Machine Design" class, our gearbox was attached to a model vehicle, and tested on both its top speed and how far it could tow a load.
In this project, I worked with 3 other engineering students to solve a problem the Tea Room, a local coffee shop, was having with composting their used coffee grounds. While they had possession of vermicomposting bins (wigwams), they were usuccessful in vermicomposting due to the acidic nature of the coffee grounds. This acidity led to the soil in the bin becoming acidic, which made the environment unhabitable for the worms. The solution was for the shop to also compost eggshells and other basic organic products along with the coffee grounds, to balance the pH of the compost.
In this project, I worked with 3 other mechanical engineering students to create a prototype wind turbine. Special care was taken to follow proper engineering design process, to satisfy the stakeholders, and to create a prototype that was effective and environmentally friendly. The prototype was tested on maximum power output and average power output over a 5-minute span in a simulation of possible wind conditions.
I've been using computers since I was 6 years old, and all that time has made me pretty good at it. Whether it's using various programs, troubleshooting, or knowing about computer hardware, I'm your guy.
Public speaking has always come easily to me. While I can get a little nervous, I'm able to harness those nerves to keep me alert and on my toes. I'm confident in front of an audience, and can speak clearly and strongly.
In my time at PnuVax, I was able to gain a wealth of experience with scale-up documentation as the company was readying to move from the lab/testing phase to the full-scale production phase.
I'm incredibly driven to accomplish my goals, and that's what allows me to work hard. It doesn't matter how much I work I have to put in if it means that I'll get where I want to go.
At school, I've used CAD programs for various projects. Solid Edge was used to design and a portable speaker system, and Siemens NX was used to model all parts of a gearbox for 3D printing. I've also used AutoCAD for work with P&IDs.
I'm Steven Maddison and I'm a 4th-year Biomechanical Engineering
student at Queen's University. I decided to go into mechanical engineering (and
specifically biomechanical) because of a long-standing passion I've had for
prostetics and prosthetic technology. Prosthetics are able to dramatically improve
a person's quality of life, and it's an emerging and exciting field. I look
forward to a future where people with physical disabilities can receieve a
replacement that is equal, or even better, than the original, and I want to be
a part of bringing that future to the present.
My hobbies include reading books, playing basketball ... or pretty much any other sport, as well as singing and playing guitar (occasionally both at once!). I am extremely curious and spend a significant amount of my time searching for answers to questions that randomly pop into my head. I believe that knowledge is power, and I try to live my life accordingly.
I'm a very honest person, and open to construtive criticism. I'm level-headed under pressure, and am able to make the right decision when the times get tough. I am an extremely fast learner, and I pride myself on being able to pick up just about anything if I'm given a little time to practice it. Professionally, I'm a good team player, and I'm willing to go above and beyond to get the job done.
