Octopus-Inspired Robotic Arms Lend a Hand in Surgery

Mashable reports that a robotic arm inspired by octopus tentacles could make it easier for surgeons to access hard-to-reach parts of the body.
A new robotic device uses a series of inflatable chambers to mimic how an octopus can twist, elongate and bend its limbs in any direction. The mechanical arm also imitates the way an octopus can change the stiffness of different sections of its tentacles, allowing the cephalopods to interact with objects.
The device could help make it easier for surgeons to reach parts of the body that are usually tough to access.
