The students and staff of Carnegie Melon University are either lazy or hate walking to the nearest vending machine in the student hall. Why? Ask Dr. Paul Rybsk. With the assistance of his students and 17 faculty members, he created the SnackBot: a mobile robot that delivers snacks throughout the campus. SnackBot is equipped with a laser navigation system, sonar sensors, and stereo “camera-eyes,” allowing it to navigate through congested environments and interact with near-by pedestrians. Every college should have one of these.
