In previous videos it was demonstrated how the robot can move like a caterpillar by periodically tilting its feet back and forth out of phase with each other. Such motion allows the robot to traverse narrow passages. This video demonstrates another advantage of such motion. Since robot's feet in this mode of locomotion doesn't need to turn full circle, robot would be able to move even if enclosed in a flexible material. For example, putting the robot in a plastic bag, waterproofs it without affecting ability to move.
