Hi,
I got the power for the robot going and it moved to the book knocking two cans off the shelf. I shot the third one off and I hit the book a few times but it didn't fall over. Do I need to keep hitting the book or hit it in a certain place? Or should I have knocked the cans down before powering up the robot?
Occasionally the elastic on the catapult ends up below the ground level and it cannot be used again.
