You would only be pentalized if it hit the floor and went outside the 84 inch diameter circle that your robot can expand to in the finale. as long as your grappling hook stays inside the circle you are fine, but if your robot is short then your grappling hook may need to extend farther and go outside the circle the finale dimensions are 7 and1/2 ft tall and an 84 inch diameter circle as stated in section 8 of the rule book. Hopefully this helps you.
