iRobot working on a robotic mower

So iRobot the creators of the robot vacuum are working on a robot lawn mower. Which to me is real cool but I can't afford either or. This article talks about how NRAO (national radio astronomy observers) is mad because it uses low power radio. So as of right now they are beefing. They call it the battle of the mega minds. But I truly thing a robot lawn mower is a cool idea. It would be bad for the economy because loss of jobs.
