A new developed approach to 3D printing has produced an octopus-inspired robotic device claimed to offer an unprecedented level of agility. Engineers crafted the artificial muscle using commercially available material and say it points to a future of advanced robotic devices inspired by nature.

"The rigidity of current surgical instruments means it is sometimes only possible to remove part of a brain tumour. Limitations such as these led Professor Paul Breedveld to develop a fundamentally new class of flexible surgical instruments, inspired by the anatomy of octopus tentacles. [...] The tentacles of an octopus are made up of an ingenious composition of muscles which work together in various layers, rings, bundles and packages. Breedveld's early instruments were based on a single ring of steel cables surrounded by coiled springs, whereas the new instruments are based on a so-called dendritic mechanism, with branched extensions. They consist of a flexible stem which ends in a number of manoeuvrable arms. Each arm is made up of a densely structured package of flexible steering elements. The instruments also possess shape memory, therefore they 'know' where we have been."

"Surgeries might be easier and safer due to a new invention by researchers from the Sant'Anna School of Advanced Studies in Italy, a robotic arm that was inspired by tentacles of an octopus. The robotic arm device moves by using its inflatable chambers, imitating the natural motion of an octopus twisting and elongating its tentacles in any direction it desires."
