Scientists have presented a new robot that can crawl on any surface. It will be useful during research missions on Earth and on Saturn’s moon Enceladus.
Researchers have unveiled a snake-like robot made up of screws and flexible artificial joints that can move over hard or loose surfaces and penetrate tiny spaces such as pipes and tunnels. This device could become a key one in the study of the icy moon of Saturn – Enceladus.
While the wheels or legs can move efficiently over a level surface, snake-like robots have several advantages. They can accommodate sharp bends, and their small cross-section allows them to crawl into tight spaces that might be blocked by other robot structures.
The researchers note that, unlike previous robots that work with wheels, the new version of the device functions on any surfaces, so it will be useful during any research and navigation missions, not just in space. In this development, they presented a new approach that combines serpentine robots with the principle of Archimedean screw locomotion to provide several effective mobility strategies over a wide range of environments.
Specifically for testing the ARCSnake robotic system, researchers have turned it on in multiple locations and environments and have proven its control and navigation capabilities. The robot was able to cope with a wide range of scenarios and successfully moved over any terrain.
