Army researchers are developing a self-aware squid-like robot you can 3D print in the field
By: Todd South
In case you weren't already terrified of robots that can jump over walls, fly or crawl, Army researchers are developing your next nightmare — a flexible, soft robot inspired by squid and other invertebrates.
And they want soldiers to be able to use 3D printers to make them on the battlefield.
The U.S. Army Research Laboratory and the University of Minnesota are developing materials that can be 3D printed based on the flexibility and nimbleness of invertebrates such as a squid, according to an ARL release.
Traditional materials are too rigid and limit certain types of movement that robots might require to get into “confined or restricted spaces,” said Ed Habtour, an ARL researcher.
The prototypes that Habtour and fellow ARL researchers developed gave 3D-printed actuators three times the movement as what's been tested before.
The material that they've used in their testing will bend in any direction when hit with electricity.
“In the initial phase of the project, our team began by investigating new methods for emulating the locomotion of invertebrates,” said Michael McAlpine, a professor at the University of Minnesota.
That helped researchers learn how to apply the natural movement of invertebrates like squids to produce “high bending motions without skeletal support,” McAlpine said.
Because the material doesn't have to be dried, heated or assembled, it would require little training and could be used for printable robots that soldiers could make and use whenever and wherever they're needed.
“If we can understand these interactions, then we can use those insights to fabricate dynamic structures and flexible robots which are 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,” Habtour said.
The material is still in early development stages, so don't expect to see a robot squid in the foxhole next to you tomorrow.

How the Marine Corps wants to improve oversight of its network
By: Mark Pomerleau The Marine Corps is creating new network battalions and companies in an effort to improve oversight and the command and control of its network. These new organizations — described as a “huge, huge deal” — are part of an effort to reduce the number of organizations charged with network functions. The move will also allow for more accurate readiness reporting, said Col. Ed Debish, commanding officer of the Marine Corps Cyberspace Operations Group. “Currently, we have six different commands that have something to do with managing the Marine Corps Enterprise Network,” he said at a Jan. 31 lunch hosted by the AFCEA Quantico chapter. Now, one commander — the head of Marine Corps Forces Cyberspace Command — will oversee and manage these groups. “Primarily, what they're going to do is deliver enterprise business services down to the end user device," Debish told C4ISRNET following his remarks. "They're also going to be responsible for managing the BAN and LAN — the building area networks and the local area networks on the bases and stations around the Marine Corps.” The new commands will absorb the organizations that previously performed many of these functions, including the Marine Air-Ground Task Force (MAGTF) Information Technology (IT) Support Centers, or MITSCs. “The problem that it was designed to solve was unity of command and unity of effort on the Marine Corps Enterprise Network. It's going to give us visibility all the way down to the end user device where we didn't have that visibility before,” he said. The arrangement will also help Marines better understand readiness of the network. Previously, it could be difficult to determine what equipment was working and part of the network. Now, with one command, those assessments should be easier, Debish said, as they'll be managed under a single entity. Additionally, the new organizations will help with one of the Marine Corps' top IT priorities: to deploy its network abroad in a more agile and mobile way. “The idea is to move that enterprise capability to the tactical edge with the deploying force,” Debish said. “If you were to just remotely connect back into the enterprise network, you're going over a VPN connection to a data center somewhere that might be thousands of miles removed from it. But if you lost that connection, then what happens? You don't have any access to any of your data or your network.” The first battalion will be created this year at Camp Pendleton. The battalion commander will assume command around April. The first company is expected to be created this year and be based out of Marine Corps Forces Europe/Africa, located in Germany. Next year, leaders expect to create the second and third network battalions at Camp Lejeune and Okinawa, respectively. https://www.c4isrnet.com/newsletters/daily-brief/2020/02/03/how-the-marine-corps-wants-to-improve-oversight-of-its-network/
