INSUBCONTINENT EXCLUSIVE:
Popular culture typically depicts military robots as unstoppable bipedal killing machines—think Battlestar Galactica’s Cylons. Even
real-life, non-violent robots, like Boston Dynamics’ somersaulting and door-opening robots, are usually designed for two- or four-legged
maneuvers. But US military researchers apparently believe that any robot with a rigid skeleton can’t achieve the maneuverability and
agility necessary for effective combat
So they’re turning to an unexpected source of design inspiration from the animal kingdom: invertebrates. The US Army Research Laboratory
announced a joint research project today with the University of Minnesota to design soft, spineless robots for “covert maneuvering” in
“highly congested and contested urban environments”. "Successful stealthy maneuvering requires high structural flexibility and
distributive control to sneak into confined or restricted spaces, operate for extended periods and emulate biological morphologies and
adaptability," said Army researcher Dr
Ed Habtour, who specializes in nonlinear structural dynamics.Squid-like robots, like the spineless crawler built by Harvard researchers seen
above, have been around for a while
But the Army’s new bots need to be much more agile to have much use in war zones. Their newly designed robot is fully flexible, made of
an elastic material that responds to electrical stimuli with a “high bending motion” in any direction

material layers will eventually fuse into one elastic material (Credit: US ARL)(Image: © US Army Research Laboratory)In the research paper
documenting their discoveries, lead author Ghazaleh Haghiashtiani said that their 3D printer “does not require post-processing steps, such
as assembly, drying or annealing”, so that new squid robots can be built quickly in combat zones with “minimal prior
expertise”.Mass-producible, fully maneuverable robots mounted with surveillance equipment, potentially capable of squeezing under doors or
sneaking silently in the shadows, could be an uncomfortably efficient asset for intelligence-gathering. Building battle-ready
squidbotsAlthough the Army Research Lab is excited about the potential of their new tech, they still have a long way to go before we start
seeing spineless robots crawling into battle. Habtour said that they’ve started studying biological organisms like cephalopods to better
understand and improve DEA’s “flexible locomotion and resilience”. Eventually, they want the robots “designed to be self-aware,
self-sensing and capable of adjusting their morphologies and properties in real time to adapt to a myriad of external and internal
conditions." Like self-driving cars need to respond to and avoid objects without human oversight, these robots will only be considered
useful if they can navigate dangerous environments and respond to threats independently. Of course, then we’ll have self-aware,
easy-to-build, unstoppable squid bots designed for warfare out in the world
We’ll wait and see how that goes for humanity. Via TechCrunchvX3qNKatAz3tyAsSh97AP9.jpg#
