Why Robots Should Grow Like Vines

Abstract

When a vine grows up the side of a building or through a crack in the sidewalk, it lengthens from its tip. This allows it to easily grow around obstacles and squeeze through small holes. Its body forms a path back to its roots, where it draws water and nutrients from the soil to continue growing. This idea has inspired growing “vine robots”, soft, air-powered robots that lengthen from the tip by pushing out material stored inside their bodies. Acting like robotic plants, vine robots can move easily through cluttered areas like vines can, and they can also do robotic tasks, like carrying cameras and other tools. This combination can help doctors reach inside the human body, archeologists see inside ancient ruins, inspectors see inside pipes, and more. It is exciting to think about how robots that grow like vines will help people in the future.
