Mechanical Engineering Capstone Day Launches Senior Design Projects (aka Capstone)

Just before graduation, George Mason mechanical engineering Senior students displayed their flagship projects during their end of year day.

students on Capstone Day

The students showed the considerable efforts made during their last year, and demonstrated the intricacies of project findings. Arranged around the atrium of the Nguyen Engineering Building and the lawn outsideprojects included a remote sensing boat, a wheelchair transfer ramp solution, and an alert system for auditory impairritated, as well as several others.

As the Director of Capstone Projects for the Mechanical Engineering program, it is a pleasure to see the hard work of students throughout the year come to fruition to a successful conclusion,” said AAssociate Professor Nathan kathir. Our program has ABET accreditation and required ABET criteriae a culminating design experience for students before graduation. Mason offers more than design experience; with 100 percent From our projects sponsored by external partners, we provide real-world experience and prepare graduates to enter the world of engineering.

Maritime RobotX Challenge

RobotX

The Hermès, Poseidon and Athéna teams have all worked together on the Maritime RobotX Challenge, which is an international university competition level. The objective is to create an automated system maritime remote control vesselwithout the need for human control on the spot.

Yasmin, Hermès team leader Alamine says this project seemed the coolest of all the capstone projects because of the international component and the ability to demo the autonomous boat in Australia.

I felt that the experience as a team leader allowed me to pursue a career in engineering consulting,” says Alamine. “We went through a lot of experiences with this project like programming learning curves (as ME)technical challenges and effective management of everyone’s time.

Jafar Hussainyleader of the Poseidon team, says the project made him appreciate the boats much more and the competition is an opportunity to put Mason on the map, and of course, to win.

“This will be Mason’s first year participating in the Maritime RobotX challenge,” says Hussainy. “Participating in this project taught me to be more flexible in my mindset and to ask for help from others.”

It was an interesting project to work on, says The Athena team leads Reginal Lockhart.

“I love engineering in all its shapes, and it was an interesting challenge to take on,” he says. “We had a navy captain who offered help and contacts within the CIA. It was a cool project.

The Maritime RobotX The challenge will take place in November 2022 in SydneyAustralia.

Wheelchair transfer Solutions

design a lightweight, portable and easy to carry wheelchair transfer device was the goal of flagship project Wheelchair transfer solutions (WTS.)

WTS

The team designed a U-shaped aluminum transfer system that could be easily disassembled and assembled. The device comes with a portable ramp so wheelchair users can use the system for a variety of purposes, such as getting in and out of a car with more ease.

“We chose aluminum as the construction material because it is lightweight and durable.“, says Joe, team member and senior mechanical engineer Barbazette. “It’s useful for traveling and being on the go.”

The system safely supports up to 400 pounds, is weather resistant and can adjust the wheelchair up to six inches vertically.

Autonomous vehicle warning systems

As their flagship project, Team Spider-Sense and Team Vibe-Vision worked on a sound recognition system for drivers with a hearing impairment. The objective is to enable a smooth adoption of autonomous vehicles by the deaf population and to improve safe driving conditions.

Warning system works by detecting sounds of potential hazards, such as a siren, and alerting the driver where does the sound come from by a real-time visual displayed on a screen near the console. Simultaneously, the driver seat cushion will be vibrate.

Team Spider Sense and Team Vibe Vision

The system has a library of sounds that the team increase include additional sounds such as barking dogs, police sirens, gunshots and car horns.

Team Member and Senior Mechanical Engineering Faiza Al-Bahrani says she uses a cochlear audience implant and for her, the autonomous vehicle warning system has an accuracy of 90%.

“I can’t always hear everything going on, and that’s a great safety feature while driving,” she says.

The feature essentially listens for you, she adds, and it can detect the location of a sound so drivers can maneuver around potential danger.

According to the team, the alert system is intended to integrate into any type of vehicle.

A podcast episode featuring student interviews from the wrap-up day is available as The Mason Mechanical Engineer, on most podcasting platforms.
