It looks almost like any other shopping cart, except sensors let it follow the shopper around the supermarket and slow down when needed so items can be placed in it. And it never crashes into anyone's heels.
"The immediate thing that jumped to my mind was all those times as a kid when my sister would accidentally hit me with a cart," said its inventor, Gregory Garcia. "It seems like the public would really want this, since everybody shops."
His cart, also known as B.O.S.S. for Battery Operated Smart Servant, was one of about 30 robots displayed last week by University of Florida students.
