A British Army commander testing war robots says they aren't always the right tool for the job

The commandant of a British Army battalion tasked pinch experimenting pinch caller technologies said that his portion has tested retired dozens of crushed robots. He concluded that they tin beryllium useful, but only for definite missions. And they travel pinch a agelong database of challenges.

As Western militaries unreserved to sorb lessons from the war successful Ukraine and merge much uncrewed systems into their respective forces, soldiers are uncovering that immoderate systems mightiness look bully connected insubstantial but aren't effective successful each combat scenarios.

Ground robots, successful particular, tin look weight, navigation, cost, and powerfulness constraints that raise questions astir erstwhile and really they should beryllium used. In Ukraine's case, the systems person seen usage successful logistics operations, replacing soldiers successful highly vulnerable areas of the battlefield, but soldiers person besides said they're not a catch-all solution.

At a caller US Army-led workout astatine Fort Irwin successful California, a fistful of American friends and partners gathered pinch US forces to research pinch caller systems successful a simulated conflict against a near-peer adversary. The British Army's experimentation unit, the 2nd Battalion, The Yorkshire Regiment, was coming for the arena alongside the portion that will return complete their experimentation role, the 1st Battalion Irish Guards.

During the caller exercise, Lt. Col. John Black, commandant of the 2nd Battalion of the Yorkshire Regiment, told Business Insider that he and his portion person seen and tested a wide scope of uncrewed crushed vehicles, aliases UGVs.

"Any usage lawsuit you tin deliberation of, we've tried it," he said, adding that they're not conscionable driving it astir to spot really it works; rather, they are focused connected "trying to employment it successful a tactical scenario."

Through that experimentation, Black and his troops person encountered problems that tin make UGVs difficult to use. For instance, galore of the medium- to large-sized UGVs they tested required trailers aliases flatbed trucks to transport. Depending connected really soldiers are moving and what they're carrying, that creates a logistical burden.

And erstwhile they've moved it into position, troops still person to fig retired really to get it into the fight.

"Even if they've sewage rather agelong scope and bully speed, there's still going to beryllium a process wherever you're moving them into the fight," Black said.

UGVs tin besides create power and refueling challenges. Depending connected the system, specifically it's size, range, and capabilities, troops successful the section whitethorn request to transportation other batteries, generators, aliases substance — aliases periodically bring the robot backmost to a charging point.

Remote power introduces different group of problems, from maintaining a reliable relationship to keeping the robot connected course. The systems tin besides struggle pinch difficult terrain.

Often, their advertised scope doesn't construe cleanly to real-world conditions, specified arsenic uneven ground. Obstacles "confound" astir UGVs, Black said.

Whether UGVs tin trust connected autonomous features is simply a peculiarly thorny subject. Autonomy has go a awesome area of liking crossed uncrewed capabilities, but Black said immoderate manufacturers person moved distant from offering autonomous UGVs.

"We person seen, complete the past fewer years, these vendors extremity offering autonomous ones because it's unworkable," he said, explaining that specified autonomous features tin consequence successful the strategy being much costly and difficult to use.

Despite those limitations, Black said location are definite situations wherever he sees value, including breaches and excavation removal.

Both missions are incredibly vulnerable for soldiers. For that reason, militaries person been utilizing remote-controlled technologies for breaching fortified positions and removing mines for decades. Certain UGVs coming online now could beryllium the adjacent improvement successful that technology, but different methods could beryllium much practical.

Ground robots are seeing increasing usage successful Ukraine, sometimes operating arsenic a safer action than sending soldiers into "the termination zone" to present supplies and ammo. Ukraine has besides utilized them offensively, specified arsenic driving 1 equipped pinch a weapon disconnected a drone vessel successful a first-of-its-kind robotic amphibious assault.

However, their increasing usage successful that conflict hasn't settled the statement connected their wide usefulness. Black indicated that they mightiness beryllium a niche tool, astir effective only successful those cases wherever keeping a worker retired of harm's measurement matters most.
