Originally a yardstick was a rod one-yard-long.  You'd use yardsticks to find out how long other items were.  People started to use the term to mean any standard they use judging similar items.  Children use the Roamer to picture how many steps they must make their robot move to hit a target.  This develops their estimation skills.
