Robot dogs armed with AI-aimed rifles undergo US Marines Special Ops evaluation

Quadrupeds being reviewed have automatic targeting systems but require human oversight to fire.

The United States Marine Forces Special Operations Command (MARSOC) is currently evaluating a new generation of robotic "dogs" developed by Ghost Robotics, with the potential to be equipped with gun systems from defense tech company Onyx Industries, reports The War Zone.

While MARSOC is testing Ghost Robotics' quadrupedal unmanned ground vehicles (called "Q-UGVs" for short) for various applications, including reconnaissance and surveillance, it's the possibility of arming them with weapons for remote engagement that may draw the most attention. But it's not unprecedented: The US Marine Corps has also tested robotic dogs armed with rocket launchers in the past.

MARSOC is currently in possession of two armed Q-UGVs undergoing testing, as confirmed by Onyx Industries staff, and their gun systems are based on Onyx's SENTRY remote weapon system (RWS), which features an AI-enabled digital imaging system and can automatically detect and track people, drones, or vehicles, reporting potential targets to a remote human operator that could be located anywhere in the world. The system maintains a human-in-the-loop control for fire decisions, and it cannot decide to fire autonomously.

On LinkedIn, Onyx Industries shared a video of a similar system in action.

In a statement to The War Zone, MARSOC states that weaponized payloads are just one of many use cases being evaluated. MARSOC also clarifies that comments made by Onyx Industries to The War Zone regarding the capabilities and deployment of these armed robot dogs "should not be construed as a capability or a singular interest in one of many use cases during an evaluation." The command further stresses that it is aware of and adheres to all Department of Defense policies concerning autonomous weapons.

The rise of robotic unmanned ground vehicles

The evaluation of armed robotic dogs reflects a growing interest in small robotic unmanned ground vehicles for military use. While unmanned aerial vehicles (UAVs) have been remotely delivering lethal force under human command for at least two decades, the rise of inexpensive robotic quadrupeds—some available for as little as $1,600—has led to a new round of experimentation with strapping weapons to their backs.

In July 2022, a video of a rifle bolted to the back of a Unitree robodog went viral on social media, eventually leading Boston Robotics and other robot vendors to issue a pledge that October to not weaponize their robots (with notable exceptions for military uses). In April, we covered a Unitree Go2 robot dog, with a flame thrower strapped on its back, on sale to the general public.

The prospect of deploying armed robotic dogs, even with human oversight, raises significant questions about the future of warfare and the potential risks and ethical implications of increasingly autonomous weapons systems. There's also the potential for backlash if similar remote weapons systems eventually end up used domestically by police. Such a concern would not be unfounded: In November 2022, we covered a decision by the San Francisco Board of Supervisors to allow the San Francisco Police Department to use lethal robots against suspects.

There's also concern that the systems will become more autonomous over time. As The War Zone's Howard Altman and Oliver Parken describe in their article, "While further details on MARSOC's use of the gun-armed robot dogs remain limited, the fielding of this type of capability is likely inevitable at this point. As AI-enabled drone autonomy becomes increasingly weaponized, just how long a human will stay in the loop, even for kinetic acts, is increasingly debatable, regardless of assurances from some in the military and industry."

While the technology is still in the early stages of testing and evaluation, Q-UGVs do have the potential to provide reconnaissance and security capabilities that reduce risks to human personnel in hazardous environments. But as armed robotic systems continue to evolve, it will be crucial to address ethical concerns and ensure that their use aligns with established policies and international law.

Giving guns to AI which is prone to hallucinations. What could go wrong?

I know this won't being much comfort to anyone, but the article didn't specify LLMs. There are object segmentation and decision making algorithms that aren't stochastic neural networks.

I’m surprised it’s taken this long with how dystopian other areas in tech like lack of privacy have become. The software to make a computer aim and fire a gun has been around for over a decade.

The video AI has been around in open source machine vision (or at least open source vision libraries + university research dataset) for at least 15 years. Similarly the kinematics math for aiming a gun has been around as long as the attack helicopter with the front mounted cannon.
A single board computer with nVidia Tegra could have powered the necessary compute without needing too much unreliable cooling or big batteries.

It would not stop a batallion in its tracks. First, 1200 .50 BMG rounds...I can't find an exact weight on the internet but 30 lbs per hundred rounds fits within several estimates. So you've got 360 lbs of ammo alone in your payload before adding the guns and everything else.

And it won't actually do much against an armored advance, they'll just use Bradleys or Russian/Soviet BMPs, armored enough to withstand .50cal and usually armed with autocannon.

What actually stops batallions in their tracks these days are RPG-7 warheads on FPV quadcopter drones. Lots of them. In swarms. And one or two up top to coordinate, and more to drop grenades on the wounded.
Legged robots will also be stopped by trenches, walls, barbed wire, and all the other things designed to stop humans from getting somewhere on the battlefield. Quadcopters are far quicker and more agile.

Boston Dynamics did some trials of their bigger legged robots with the marines many years ago, and the end conclusion was that they were too loud to be useful: US marines reject BigDog robotic packhorse because it's too noisy . There are some niches where a land robot makes sense, like bomb disposal, and there will probably be people who are convinced to get legged robots in spite of their unsuitability, but there's good reasons why legged robots are still doing trials and quadcopters are actively being used in warfare.
