Freshman Si Ya “Wendy” Ni Presents Semi-Automatic Subway Track Cleaner at White House Science Fair
In April 2016, President Obama hosted the annual White House Science Fair to showcase the work of young students who excel in science and mathematics. Over 130 students displayed their projects at the fair, including Si Ya “Wendy” Ni.
Ni began her engineering project while attending Baruch College Campus High School in New York City. Her team of 11 received a Lemelson-MIT InvenTeam grant of $10,000 with their proposal for a semi-automatic vacuum cleaner. The teams include students, educators, and mentors who invent solutions for real-world problems. The vacuum was designed to clean the subway tracks of New York. It attaches to the flatbed car of a work train, and is semi-automatic using light and ultrasonic sensors and four pneumatic cylinders.
