Such adaptive techniques might eventually help robots trek across the many different surfaces and environments found in the real world, without having to tote an extra propulsion system that might make them move less efficiently. Kramer-Bottiglio’s team found that ART uses about the same amount of energy as robots built for just one environment. Mr Toys may elect to return the product to the manufacturer's repair agent to determine the nature of the problem.

A new transforming turtle robot can explore treacherous regions where the land meets the sea—and may lead to future machines that navigate complex real-world conditions. This article was originally published with the title "Mighty Morpher" in Scientific American 328, 1, 13 (January 2023) Integrating both soft and traditional robotics gives ART its transforming ability, says Tønnes Nygaard, a roboticist at Oslo Metropolitan University, who did not contribute to the new study. “Very strict, rigid modes of locomotion [are] a necessity when you use traditional robotic techniques,” he adds. “But now with techniques like these from soft robotics, you might be able to do something that’s a bit more fluid.”

Combining the best mobility features of an ocean-swimming turtle and a land-walking tortoise, the Amphibious Robotic Turtle (ART), described recently in Nature, can morph its limbs from turtlelike flippers to tortoiselike legs. “Most amphibious robots … use dedicated propulsion systems in each environment,” says Yale University roboticist Rebecca Kramer-Bottiglio, who is the senior author on the paper. “Our system adapts a single unified propulsion mechanism for both environments: it has four limbs, and those limbs can transition between a flipper state for aquatic locomotion and a leg state for terrestrial locomotion.” Where a failure does not amount to a major failure, Mr Toys is entitled to choose between providing you with a repair, replacement or other suitable remedy. The robotic tortoise isn’t at the finish line yet: the current prototype still requires a tether to provide power and communication, and its movements are slow and awkward. But the researchers are working to improve these issues. “I’m very excited to see how far they’ve come,” Nygaard says. “And I’m very interested to see what will come out of this group in a couple of years.”
