Use the hand to rotate the large gear wheel or select the play button to see gears and legs in motion. Notice how the teeth on the gear wheels interlock with each other to produce motion and power that is transferred from one leg to the next. Scuttle uses its eight legs much like the wave of a centipede with each leg running out of phase with the next. This means that on either side of the robot, only one leg at a time touches the ground. When the last leg touches down, the first one is just coming into place to do the same in continuous sequence.
