It constantly just stares at the animatronic prisoners while they try to get the worm to trade the prison key in his mouth for either a bone or a leash. It is one of the many animatronics in Glove World! Jail. It holds a golden prison key in its mouth. It is a small light green robot worm with yellow eyes and black pupils.
The animatronic guard worm is a robot worm who appears in the episode " Escape from Beneath Glove World." Who knows: Maybe worm robots in space isn’t quite as crazy as it sounds!Ī paper describing the work was recently published in the journal Science Robotics." Escape from Beneath Glove World" List of characters However, the team is currently collaborating on a project with NASA to cover some of these exact applications. The idea of using this technique to explore low-gravity environments in space might sound farfetched. “Example applications include thermal sensor placement on Mars, volcanic tunnel exploration on the moon, asteroid sampling or anchoring, and granular ice exploration on Enceladus, a moon of Saturn.” It’s that “more,” perched non intrusively on the end of granary inspection, that makes for the most compelling (and science fiction) use-case of them all. “We think that the robot is particularly well suited for dry, low-gravity, extraterrestrial environments, where reactive forces may be difficult to produce,” continued Naclerio. “Other applications include search and rescue, geothermal loop installation, granary inspection, and more.”

“One of the earliest visions we had for this project, is that the robot would burrow down, under, and up on the other side of a driveway to install an irrigation or communication line without the need to dig a trench,” Naclerio said. So what applications could this burrowing snake/vine robot have, then? And, more importantly, could it be scaled up to displace large quantities of sand or earth? “We believe that the principles presented in this paper could be used to expand the capabilities of conventional burrowing methods, particularly in horizontal and steerable burrowing,” said Naclerio.Īs far as use-cases go, the more pedestrian terrestrial ones might include assorted ditch-digging activities. We addressed this by blowing air straight down, to reduce the strength gradient that causes lift, and by adding wedge to the tip of the robot.” Burrowing snake robots on the moon “It turns out that a symmetric object moving horizontally through a granular media experiences lift, because it’s easier to push material up and out of the way than it is to compact it down. The elongated robot will slither along terrains in space using spinning wheels on its body and its target is the vent systems on Saturns small icy moon Enceladus. “When we first tried to burrow horizontally, our robot always surfaced,” he said. This unique design helped the team to overcome the “challenge of lift” in horizontal burrowing. This was inspired by the sand fish lizard, which uses its wedge-shaped head to help it burrow into sand.” UCSB Hawkes Lab Lastly, we used an asymmetric airflow direction and angled wedge at the tip of the robot to help control lift forces. Our robot blows air from its tip to fluidize the sand near its tip, reducing the force it needs to burrow into the ground. We also took inspiration from the southern sand octopus which expels a jet of water to help burrow into the seafloor. “By extending from its tip, the robot avoids friction along its sides, and can turn in any direction. “Our robot is directly inspired by plant roots, which grow from their tips to extend deep into the soil,” Naclerio said. Naclerio said he was unfamiliar with the Tremors Graboids (although the Sandworms of Dune are another story.) In fact, while the robot was definitely nature-inspired, it seemingly wasn’t based on worms or snakes at all. The robot’s movement is pneumatically driven by compressed air or nitrogen, allowing it to move under the surface. Just like a real inchworm, the robot extends its body, attaches its front foot (aka pressure. A carbon fiber braid adds torsional stiffness, while a Teflon sheath reduces friction. The pneumatic actuators and suckers work together synchronously propel to the robotic inchworm forward. A nylon tube supplies air to its tip, which blasts aside the particulate in front of it to clear a path as it wends its underground way. Its body is made of an airtight, ripstop nylon fabric. The robot itself is surprisingly low-tech. Robotic burrowing with tip extension and granular fluidization Sandwormvines go digging
