SnackBot back with a vengeance

The SnackBot started off as a brainchild among students at the University of Pittsburgh and Carnegie Mellon University back in 2001 in the form of a Nursebot known as Pearl who rolled around offering snacks to old folks in retirement homes. 10 years later, you get a new and improved SnackBot that uses verbal and non-verbal communication to assist humans in everyday life, where one is able to interact through a touchscreen interface, coupled with a laser range finder and cameras, will help it perform research navigation, path-planning, and people/face detection at its optimal level in an office environment.
