A mall security robot has effectively redefined the term artificial intelligence after it barreled into a toddler last week at a northern California shopping center, running him over and leaving him with various bumps and bruises. The robot, weighing in at 300 pounds and standing at 5 feet, is typically an attraction for patrons at the Stanford Shopping Center in Palo Alto. But this time around it was more of an attractive nuisance, the 16-month-old boy's mother told KGO-TV, the local ABC affiliate. "The robot hit my son's head and he fell down facing down on the floor and the robot did not stop and it kept moving forward," said Tiffany Teng said. The runaway robot caused the young boy to experience a sore head, swelling in a foot and bruising on a leg.
