"It's the claw machine all over again," said a flustered Mac Cline as he tried to maneuver his robot to pick up a hexball on the giant game board last week. Cline and his classmates paired up and faced off against one other as their robots worked to score on the playing field. The battling robots tucked away in the in-school suspension room at the back of Dawson County Middle School are now a part of the curriculum thanks to a mini-grant received through the Dawson County Schools charter.
