Abstract: A method for forming a glass sheet includes forming a glass ribbon. A robot arm is operated to move an end effector through a preprogrammed cycle. The cycle includes engaging a segment of the glass ribbon with the end effector, separating the engaged segment from the glass ribbon to generate a glass sheet, and moving the glass sheet away from the glass ribbon. The preprogrammed cycle designates predetermined positions of the end effector at predetermined points in time. While the robot arm is operating through the preprogrammed cycle, a parameter indicative of a force being exerted on the glass ribbon by the end effector is sensed. A position of the end effector is altered to differ from the predetermined position at the corresponding point in time when the sensed parameter deviates from a target value. An excessive force applied to the glass ribbon can be reduced in real-time.
