Security Robot Suspended After Colliding With a Toddler

A mall in Silicon Valley this week suspended its security robots after a collision involving one of them resulted in a toddler getting a bruised leg--a reversal from children harassing robots at the mall. The accident could reignite fears about evil robots that many robot makers have tried to overcome with cute designs. The robot company, Knightscope Inc., designed its 300-pound machine to protect against malicious humans. Children usually present the greatest risk to robots' ability to get their jobs done, previous incidents showed. Knightscope was the subject of a Wall Street Journal page one article last month.
