Robot Octopus Shows Off New Sculls

Robot Octopus Shows Off New Sculls | Biomimicry | Scoop.it
"Octopi are pro swimmers, thanks (at least in part) to that octet of arms they've got going on. They've adopted a particular swimming gait called sculling, which works great for them, but until they start publishing scientific papers, we're missing out on all of their gait testing data. Roboticists have had to start from scratch, and along the way, they've experimented with some swimming gaits that we've never seen a real octopus try and pull off."

How Squid and Octopus Might Point the Way to Nanotechnology-based Stealth Coatings

How Squid and Octopus Might Point the Way to Nanotechnology-based Stealth Coatings | Biomimicry | Scoop.it

"For a long time, scientists have been fascinated by the dramatic changes in color used by marine creatures like squids and octopuses, but they never quite understood the mechanism responsible for this. Only recently they found out that a neurotransmitter, acetylcholine, sets in motion a cascade of events that culminate in the addition of phosphate groups to a family of unique proteins called reflectins. This process allows the proteins to condense, driving the animal's color-changing process. The latest findings revealed that there is a nanoscale mechanism behind cephalopods' ability to change color."

3-D Printed Octopus Suckers Help Robots Stick

3-D Printed Octopus Suckers Help Robots Stick | Biomimicry | Scoop.it

"Legions of animal-inspired robots are being created to improve military missions and disaster response efforts—from crawling cockroach-like RHex bots to leaping Sand Flea robots and the speeding Cheetah machines. Now, a squishier source for smart robo-tech has joined the ranks: octopuses."

This article invesigates biomimetics, 3D printing and the prospect of better grip for robotic hands. As control over the suckers improves, the way could be opened for less rigid gripping digits. This may overcome some of the challenges associated with robots gripping unknown and irregularly shaped objects.

'Octopus Tentacles' Make Future Operations More Flexible

'Octopus Tentacles' Make Future Operations More Flexible | Biomimicry | Scoop.it

"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."

Octopuses Inspire 3D-printed Propulsion Systems for Boats

Octopuses Inspire 3D-printed Propulsion Systems for Boats | Biomimicry | Scoop.it

"Octopuses and squid are amazing animals. Their unique attributes have already inspired invisibility cloak technology and more comfortable medical implants. Now, their ability to flee quickly from predators has inspired a new propulsion system for boats and other water craft."
