ShelfStocker Leonard Andrews, Justin Dick, Nasreen Lowder, Piper Smith WebSite A.K.A. Computer Engineering Senior Project University of Utah Fall 2001

Original Project Objectives The ShelfStocker will be a robot that reads in a bar code label and then stocks the item in a particular location based on that label. Automates a lot of shipping and receiving work in a general way. Can be scaled to any size product using different bodies.
