Robotic “tentacles” that can grasp and grapple with a wide variety of objects have been developed by US researchers.

Most robots rely on mechanical gripping jaws that have difficulty grabbing large or irregularly shaped objects. Replacing these with tentacle-like manipulators could make robots more nimble and flexible, say the scientists.

The tentacle-like manipulators, known as “Octarms”, resemble an octopus’s limb or an elephant’s trunk.
