How’s this for a sweet new invention: five students from Franklin W. Olin College of Engineering have built a cake-decorating robot for a class project.

Called AutoFrost, the machine combines electronic sensors, computer programming, and precise mechanics with delicious gooey confections. Just doodle your design on a basic Microsoft Paint-like program, hit the button that says, “I’m ready to design an amazing cake,” and watch the frosting begin.
