According to this article there is a robot that can mimic the movement of a worm.
Soft robots have emerged as a new frontier in robotics technology, offering exciting possibilities for a wide range of applications. These robots are made of materials that are flexible, stretchy, and can deform easily. As a result, they can move in ways that traditional robots cannot, making them ideal for tasks that require a high degree of dexterity and adaptability. These traits make soft robots well suited for applications in many fields, including medicine, manufacturing, and search and rescue.
Many soft robots are modeled after creatures found in the natural world, which have soft bodies that allow them to move in unique ways. For example, a soft robot inspired by an octopus might have tentacles that can bend and stretch in all directions, allowing it to grip objects in a variety of ways. Similarly, a robot inspired by a jellyfish might have a bell-shaped body that can contract and expand, allowing it to swim through water in a fluid motion.
