If the arm is built so that it's pivoting mount is at one end of the robot, and the arm is less than 72" long fully extended, you'll be ok. Consider making the arm so that it only can pivot up and down, it cannot swing sideways (or not very far sideways). A 66" long (total extended length) arm/hand mounted on a 56" high mast at the "back" of a robot, would be able to reach the floor and also score high ringers, I think. Make some sketches, see how the geometry works. There seems to me to be no need to make the robot extend further than 72" in length/width to perform it's task.
