Awesome!

A new soft robot designed by researchers from the University of California, Santa Barbara can ‘grow’ like a plant — only much faster.

A team from Stanford Uni and the University of California, led by Elliot Hawkes of UoC’s Department of Mechanical Engineering designed and build a prototype soft-robot that can grow to explore its environments, akin to a vine of fungus. The design could help create a new class of robots which can traverse cramped or otherwise constrained environments.

The robot’s mechanical body is housed inside a plastic tube reel. The tube can be pneumatically extended, in a manner similar to how some invertebrates (such as Sipunculus nudus, the peanut worm) move around.

The plastic tube also allows the robot to change direction — one component handles the inflating process, while another allows the whole thing to shift direction. To see when it’s about to run into something, the robot also comes equipped with a nose-mounted camera.

Overall, the robot can extend up to 72 meters in length, at a speed of 10 meters per second. As a proof-of-concept of their prototype bot, Hawkes’ team had it crawl through flypaper, glue, even over a bed of nails.

They even programmed it to form various 3-D structures (such as a radio antenna), used it to turn off a valve, and had it act as a fire extinguisher.

A paper describing the robot, titled “A soft robot that navigates its environment through growth,” has been published in the journal Science Robotics.

Stunningly charming pun connoisseur, I have been fascinated by the world around me since I first laid eyes on it. Always curious, I'm just having a little fun with some very serious science.
