Fresh from their win at the Millard Chan Tech Challenge, the team behind MilkShaker demonstrated a practical and science-backed solution to prevent mastitis, providing professional level care without sacrificing time or requiring special training. Another group of seniors in the Department of Mechanical Engineering showcased a prototype for the CareCruiser, a wheelchair-to-stroller attachment designed to give wheelchair-using parents and caregivers greater independence when navigating with strollers and carseats.

Several projects also tackled infrastructure design, including a civil engineering and engineering mechanics team that unveiled Rethinking Resilience. The project envisions a new sustainable, flood-resilient train station to replace the existing Ardsley-on-Hudson station along the MTA’s Metro-North Hudson Line. 

And in the gaming arena, a team from the Department of Electrical Engineering demonstrated their physical tank game using modified remote-controlled cars. By reconfiguring the electronics of remote-controlled cars, the team enabled Bluetooth-based control of both the motors and onboard lasers. Players score by hitting opposing cars with laser pulses, while any car that gets hit is temporarily disabled with a five-second freeze penalty.

Dean Shih-Fu Chang greeted the students and commended them on their year-long efforts. “You all have started with an idea and brought it to life. That’s what engineers do! We bring ideas to life . . . Today’s showcase truly represents our Engineering for Humanity vision. This is a milestone in your Columbia experience and one I hope you remember for years to come.”

Each year, Columbia Engineering seniors work on a capstone project, aka Senior Design. They are challenged to solve real-world problems with innovative solutions, rooted in their foundational math, science and engineering courses. 

Here’s a look at some of the students and their innovations at Senior Design Expo 2025.

A day of innovation, teamwork, and STEM spirit

"We are so happy to have you here, and we hope to do more with New York City schools and our partners to share and promote our love of STEM,” said Dean Chang. “Columbia Engineering has a long history of supporting FIRST Robotics teams with mentors–we have hosted the FIRST Robotics kickoff for multiple years and plan to do so again in 2026.” 

Dean Chang also noted that more than 40 students from the Engineering School had signed up to volunteer. “Many of our engineering students are FIRST alumni, as well. They have personally benefited from this program and they know the impact being on a robotics team in middle or high school can have on a young person's life.”

“Today’s competition is more than just a contest. It is a testament to the dedication, the creativity, and the hard work of each and every one of you,” said Ray while addressing the students. “The innovation and approaches you took to source materials and build your projects were truly remarkable – it’s very inspiring.”

To win the robot challenge, alliances of two teams would compete against another alliance–and challenge their robots with a series of tasks, from collecting blocks and disposing them in the team’s bucket, or retrieving hooked blocks to hang in the middle of the arena. The Mayor’s Cup came to an exciting conclusion when the last two teams of alliances competed for first place. Teams Saturn and Mercury, an alliance team took home the first place trophy. Both teams were made up of students from the Staten Island Technical High School.

Robotics demos and campus exploration

In addition to the full day of competitions, Columbia Engineering faculty members presented a series of robotics demos. Highlights included demonstrations from Hod Lipson’s Creative Machines Lab, Sunil Agrawal’s ROAR Lab, Yunzhu Li’s RoboPI Lab, and Matei Ciocarlie’s ROAM Lab. The School’s Office of Outreach also showcased a creation from their flagship program SHAPE (Summer High School Academic Program for Engineers), a summer program that offers college-level courses taught by Columbia faculty. 

Additional demos were showcased by student groups representing the Engineering School, including Columbia Space Initiative, Columbia Robotics Club, Biomedical Engineering Society, and Columbia University Formula Racing. High school students participating in the competition also had a chance to tour the School and learn more about student clubs from Columbia students who shared demos of their past work.

“Thank you to the students for really putting in the effort to make this day a reality,” said Zigman at the competition. “Many of you will go on to careers in STEM, but for those of you who don’t, you’re going to be incredibly successful because of the mindset and skills you’ve learned that will serve you well in anything you choose.”
