"OU professor invents robotic lawn mower"

"Have you ever wished your kid would mow the lawn without complaints or excuses? OU engineering professor Ka C. Cheok has a better way to get the task done. He has invented a robot that will do the task and it won't ask for an allowance. His robotic lawn mower is designed to start up at a preprogrammed time set by the owner, drive itself out of the garage, mow the lawn, and then put itself away for recharging."
