These teenage sisters have taught robotics to youth around the world

Twin sisters Hannah and Rachael Tipperman have taken their youth robotics class, Robot Springboard, to Alaska, Costa Rica and Philadelphia — to Drexel, to be precise.

The Tippermans, 17, are rising seniors at The Baldwin School, a private school for girls in Bryn Mawr, Pa. They’ve won about $7,500 in grants from the National Center for Women & Information Technology to bring the program, designed specifically for middle school girls, to Drexel two years in a row, the Philadelphia Inquirer reported. (The same grant helped a Penn student run a programming camp for girls last summer.)

Robot Springboard will begin at Drexel next month. The program, which costs $50, is already at capacity but you can sign up for the waitlist (and to get to the top of the list for next summer) here. It’s one of several summer youth STEM programs hosted by Drexel.

The Tippermans work with Drexel computer science professor Jeffrey Popyack to run the program at Drexel. Popyack is also the faculty advisor for another STEM outreach effort, the Drexel University Computer Science Teach group that teaches programming at Philly schools.
