  • Barracuda cruise missile family targets discount swarm capacity

    Barracuda cruise missile family targets discount swarm capacity

    [ad_1]

    In response to the return to large-scale peer-to-peer warfare, Anduril has unveiled its new Barracuda family of autonomous cruise missiles, which can be built to “hyper-scale” for intelligent swarm attacks against hardened targets.

    The current geopolitical situation and conflicts in several parts of the globe have shown that the decades of counterinsurgency warfare after the Cold War is giving way to a return to the threat of massed armed forces facing off against one another.

    This is more than just a serious threat to world peace, it also highlights a major shortcoming for Western military powers. As the aid sent to help Ukraine fight the Russian invasion has shown, Western weapon stockpiles may include some remarkable state-of-the-art hardware, but those stockpiles aren’t very deep and would be rapidly depleted in a serious conflict.

    The Barracuda 100

    According to Anduril, the problem is so severe that the West’s reserves of precision weapons could be exhausted in a matter of days. If this wasn’t bad enough, such precision munitions are no longer designed to act alone. They are becoming increasingly autonomous and designed to work together as a team, independently deciding which targets to hit and which weapon to do the hitting.

    What this all boils down to is that the West needs to build up its stockpiles. And fast.

    The Barracuda family of three variants of Autonomous Air Vehicles (AAVs) is designed to address this.

    The Barracuda 100, Barracuda 250, and Barracuda 500 are air-breathing, software-defined expendable AAVs, with each variant having increased size, payload, and range. Each variant’s number indicates the turbojet-powered missile’s range in nautical miles: 100 nm (115 miles, 185 km), 250 nm (287 miles, 463 km), and 500 nm (575 miles, 926 km). They have a payload capacity ranging to over 100 lb (45 kg), can handle maneuvers at 5 gs, and can loiter for 120 minutes for direct, stand-in, and stand-off attacks.

    However, what sets the Barracuda family apart is that all share a common design that is compatible with a range of mission payloads. This configuration is intended to simplify not only the missile’s architecture, but to make it easier, cheaper, and faster to produce in large numbers.

    Instead of being highly complex and requiring specialized tools and technicians to put them together, the Barracuda has a software-defined modular design that, according to the company, allows it to be assembled in half the time of conventional missiles, while requiring 95% fewer tools and 50% fewer parts. Overall, this makes it 30% cheaper to make and suitable for mass production, including short-term surge demand.

    Not only does the Barracuda only need fewer than 10 tools to put it together, it doesn’t require the specially trained technicians that other missiles require. This means it can be built on standard automotive and consumer electronic factory lines, which gets through the bottleneck plaguing modern defense industries that have merged into a handful of companies. In addition, the Barracuda uses off-the-shelf components for its subsystems, which helps with logistics.

    The Barracuda uses Anduril’s Lattice for Mission Autonomy software, which allows it to be both collaborative and autonomous. This means it doesn’t just home in on a target, it can be deployed in intelligent swarms to work with other missiles and piloted aircraft, making decisions and delegating tasks, such as which missile will be best suited to taking out which target, whether to head in or loiter, act as decoys, and in what sequence the attack should be carried out for maximum effect.

    “That package can deliver the mission effect that you want, without having to bundle all of that into one air vehicle, and then radically drive up the cost per round of every single vehicle,” said a company spokesman.

  • Iron-shelled robo-snails swarm together for off-road tasks

    Iron-shelled robo-snails swarm together for off-road tasks

    [ad_1]

    Even though snails are slow and slimy-bottomed, they’ve inspired a new type of robot that could be quite useful. Groups of these bots can operate independently or join together in order to perform tasks that would otherwise be impossible.

    In recent years we’ve heard a lot about “swarm robotics.”

    This concept involves utilizing small robots that can work either on their own or as one facet of a group of identical bots. In the latter scenario, all the robots communicate with one another, coordinating their movements in order to get the job done.

    That job might entail searching for survivors at disaster sites, performing reconnaissance in hazardous environments, or even exploring the surfaces of other planets.

    For some applications, the robots have to physically link up with one another.

    Because aerial and underwater bots can move both horizontally and vertically, they’re able to form three-dimensional shapes when joined together. By contrast, because terrestrial (ground-going) robots can only move horizontally, they’re limited to forming two-dimensional shapes – thus limiting their potential uses. What’s more, most of the experimental models created so far can only move across smooth, flat surfaces.

    Things would be different, however, if there were “off-road” terrestrial bots that could climb up on top of one another, stacking themselves into three-dimensional configurations. That’s where the new snail robot comes in.

    Developed by Da Zhao and colleagues at The Chinese University of Hong Kong, the device was inspired by the White Jade land snail. Like that gastropod, it can move itself along while doing a pretty good job at sticking to surfaces, but then stop and use suction to form a much stronger bond when needed.

    The robot has a spherical ferromagnetic iron shell, inside of which are a battery, microprocessor and other electronics. On the bottom of that shell is a set of tank-like tracks made of rubber with embedded magnets. A retractable vacuum-powered suction cup is located between the two tracks.

    When the robot is moving in “free mode,” the suction cup is kept withdrawn and unpowered. The bot simply moves across both smooth and uneven terrain on its tracks, utilizing the magnets in those tracks to climb up on top of the shells of other snail robots.

    Once it’s in place up there, the bot switches to “strong mode” by lowering and powering up its suction cup. That cup then clings tightly to the shell of the other robot, holding the two bots firmly together. That said, the robot’s shell can still rotate relative to the cup, allowing it to pivot on the spot without losing suction.

    In outdoor tests performed so far, swarms of the snail robots have worked together to perform tasks such as climbing up over ledges, making their way across gaps, and forming a single robotic arm. Although the bots were remotely controlled for these experiments, it is hoped that their descendants could one day do such things autonomously.

    You can see the snail robots in action, in the video bellow. A paper on the research was recently published in the journal Nature Communications.

    And should you be disappointed that the bots don’t look that much like real snails, check out the self-healing robo-snail that was created last year at Carnegie Mellon University.
