Many accessibility surveys depend on manual measurements, handwritten notes, and extensive walkthroughs with compliance checklists. A team of 911�� engineering students wondered if a robot could do it faster. Nine months later, they created one.

The project, called Salus, combines robotics, LiDAR technology, object detection, GPS mapping, cloud-based analytics, and a custom-built website to help survey public spaces for potential ADA accessibility barriers. Developed as part of a College of Engineering and Computing senior capstone project by mechanical engineering majors Lexi Chivers, Connie Lam, Mariah Tammera, Noemi Umanzor, and Tyler Yared, the system is designed to automate portions of the accessibility surveying process while allowing engineers and designers to better understand how people with disabilities experience physical spaces.

Salus was one of several 911�� capstone projects supported through a GO Virginia-funded initiative led by the Nexus234 Innovation District, which pairs students with industry-informed challenges and mentors.

“We saw a system that was operating poorly, and we wanted to optimize it,” said Chivers, the team lead.

The idea originated when one of Chivers’ teammates attended a conference and discussed the difficulties of collecting large volumes of survey data in the field with industry professionals.

“They basically said, ‘We wish we had something we could send out to collect data and not have to constantly manage,’” said Chivers. “That conversation sparked everything.”

The project consumed most of the team’s weekends as they worked through testing, software integration, fabrication, and constant iteration.

“A lot of people told us we weren’t going to be able to do this in nine months,” said Chivers. “At one point, someone told us it would take two years and eight NASA engineers.”

Instead, the students delivered a working proof of concept before graduation.

As the robot moves through a space, it uses LiDAR sensors, GPS mapping, and onboard cameras to identify and document potential accessibility issues. The data is processed through cloud-based systems and displayed through an interactive website. Rather than sorting through raw data, users can explore flagged locations through an interactive visual map built by the team.

For Chivers, the project also had a personal connection. She said her mother’s job teaching students with disabilities influenced the team’s conversations around accessibility and inclusion. “Just because something legally meets ADA standards doesn’t always mean it’s truly accessible for those with disabilities,” she said.

Kenan Aden, COO of Didlake and the team’s industry mentor, was introduced to the student team through Nexus234. He said the project impressed him both from its technical complexity and for the problem it set out to tackle.

“The entire team approached this project with an incredible level of determination and systems thinking,” said Aden. “What makes it especially meaningful is that they never lost sight of the people this technology is intended to help.”

"This team’s focus and dedication have been extremely impressive," said Leigh McCue, professor and chair of 911��’s Department of Mechanical Engineering. "Any time I popped my head into the senior design space, or walked visitors through for a tour, the team was hard at work and eager to showcase their technology."

One of the most rewarding parts of the experience for Chivers was discovering the kind of engineer she wants to become.

“I thought I wanted to stay in the background,” said Chivers. “But this project made me realize I really love being a leader, solving problems, and doing things that actually matter to people.”

Currently, the students are working with 911��’s Office of Technology Transfer to explore patent protection for the project’s intellectual property. Although the team is still deciding what comes next, Chivers said the technology has potential beyond the capstone project itself, including with construction firms, municipalities, designers, and accessibility planners.

In her advice to other entrepreneurs, Chivers said, “Your dreams are never too big. You just haven’t found all the tools you need to make them happen yet.”

911�� engineering students turn personal experience into accessibility innovation

911�� engineering students turn personal experience into accessibility innovation ckearney Tue, 06/02/2026 - 16:58

For Owais Yousuf, inspiration began at home. His father, who contracted polio as a child, relied on crutches to move through daily life. Growing up, Yousuf watched him navigate airports and crowded spaces with difficulty. Three of his fellow 911�� mechanical engineering students had similar experiences with relatives who struggled with mobility. The four of them began wondering: How do you make airport travel more independent and less stressful for people with mobility challenges?

The answer to that question became B-Drive, a senior capstone project developed by Yousuf, Turner Applegate, Javier Carpio Jota, and Calvin Nguyen that combines autonomous navigation, computer vision, and adaptive mobility technology to help wheelchair users move through transportation hubs on their own terms.

B-Drive was one of several 911�� capstone projects supported through a GO Virginia-funded initiative, led by the Nexus234 Innovation District, which pairs students with industry mentors and opportunities to address pressing needs.

"The people we love aren't just statistics," said Yousuf, the team's lead. "They're people we care about. We've seen the frustrations they face firsthand. That experience gave us the context to build something that could provide them some relief."

As the team dug deeper, they found that navigating a large airport can present obstacles at nearly every step. Long walks, unfamiliar layouts, limited assistance, and confusing signs can make traveling on their own difficult for many passengers.

To better understand those barriers, the team participated in the National Science Foundation's I-Corps program, which helps entrepreneurs move a business idea or discovery toward licensing or commercialization. Program participants assess the commercial viability of their idea by conducting customer interviews and working closely with a mentor. Yousuf and his team spoke with travelers, transportation professionals, accessibility advocates, and industry experts.

"We consistently heard that people wanted the freedom to move through an airport with greater dignity and confidence," said Yousuf.

Those conversations led to B-Drive. The team decided early on that B-Drive needed to fit into existing airport operations, so they designed it to work with wheelchairs already found in many airports.

Bringing B-Drive to life required more than technical expertise. After delays in obtaining testing equipment, the team drove to New Jersey to buy a wheelchair themselves rather than wait.

Their persistence impressed Robert "Bob" Schneider, executive director of OmniRide and the team's industry mentor, who was introduced to the students through Nexus234.

"They didn't let anything stop them. They went out and got it done," said Schneider.

Schneider guided the students as they narrowed the project's scope and found a realistic way to put their ideas into action. He suggested the team pick one clear, manageable use case. They decided to focus on a journey that’s familiar to many travelers at Washington Dulles International Airport: getting from the Silver Line Metro station to their destination inside the airport.

As the project progressed, the students began thinking beyond the classroom. The team is currently exploring intellectual property protection and potential avenues for commercialization through 911��'s Office of Technology Transfer.

Leigh McCue, professor and chair of 911��’s Department of Mechanical Engineering, believes that moving from classroom projects to real-world applications is among the most valuable lessons for students.

"One of the hardest parts of engineering is defining the right problem to solve," said McCue. "This team resisted the temptation to build technology for its own sake and grounded their approach in the experiences of the people they aimed to empower.”

The project also prompted Yousuf to rethink what it means to be an engineer. "Engineering is ultimately about people," said Yousuf. "Technology is only valuable if it improves someone's life. That's what motivated us from the beginning, and it's what continues to motivate us now."

Graduation marked the end of the capstone project, but the team hopes B-Drive's story is only beginning. The goal remains the same for Yousuf as when the project first started on a whiteboard.

"We're not going to stop until we bring a smile to people's faces," said Yousuf. "That's what this has always been about."
