A virtual reality piano, 3D-printed concrete, and robots (lots of robots!) were just some of the marvels on display at this year's showcase of innovative work by engineering students and faculty. The annual event showcases dozens of the most promising and exciting research projects from every academic department within the Tandon School, as well as exhibits from the school’s Center for K-12 STEM Education, which is dedicated to boosting science, technology, engineering, and math education in New York City’s public schools.
