Captured Russian soldiers have a rule for one stretch of the Kupiansk front: go anywhere, but not there.

That stretch is the “safety corridor” the “Orion” unit of Ukraine’s Offensive Guard brigade “Pomsta” says it has built for its ground robots. The zone is so lethal that, by the unit’s count, 88% of attacking Russians are killed before they reach their positions, and Russian armor cannot get within 25 kilometers, the military outlet ArmyInform reports.

Behind that shield, the unit says its ground robots have run dozens of fully autonomous missions through the most dangerous ground on the axis, with a success rate of 99.57%. The results made Orion the top-ranked unit for effectiveness on the South-Kupiansk axis in September within Ukraine’s battlefield management system, DELTA.

“You can go anywhere, just not into the Orion zone”

The claim that the Russians now avoid the sector, the unit says, comes from them themselves.

“Prisoners admit in interviews: 'You can go anywhere, just not into the Orion zone.' Eighty-eight percent of the enemy is destroyed before reaching their positions, and Russian equipment cannot approach closer than 25 kilometers,” the unit says.

That is what opens the corridor. Where a human supply run would be a death sentence, a robot can cross, and cross again.

The quiet blood of the front

The point, the unit says, is to take the soldier out of the deadliest job on the front: carrying ammunition and the wounded across open fire.

“We broke the stereotype that supplying the army takes truck convoys and hundreds of soldiers under targeted fire. Our robotic systems are the ‘quiet blood’ of the front,” Vladyslav Zolotarov, an officer in the unit’s staff control group, says.

When Russia thinks our positions are depleted, a tracked platform quietly comes in at night and brings in a ton of ammunition.

In September alone, the unit says, its wheeled and tracked robots ran 85 of the hardest combat missions and hauled more than 30,000 kilograms of cargo. Its evacuation record is the line it is proudest of: four missions pulling wounded soldiers out by robot, all four successful, not one man lost.

Ukraine has bet heavily on this kind of machine, aiming to field 50,000 ground robots to keep its troops out of the drone-ruled kill zone.

Ukrainian company Nodrics has developed MAT1LDA, an eight-wheeled amphibious ground robot that can carry supplies across water, swamps, and rough terrain, robot-maker Tencore said, Ukrainian military outlet Militarnyi reported on 17 October. The machine joins Tencore’s new family of ground robots, which the company has also shown in the US.

Ukraine’s ground robots now haul supplies and evacuate wounded soldiers through zones where drones make every move deadly, and the Defense Ministry has launched its first competitive tender for them.

500 kg on land, 400 kg afloat

A petrol engine drives MAT1LDA’s eight wheels, and side pontoons keep it afloat, so it can cross water, marshland, and rough ground without preparation, Militarnyi said. Its makers claim it carries up to 500 kg on land and 400 kg on water, with a range of up to 160 km on land and 50 km on water.

Its open frame lets crews swap equipment quickly to suit the task, fitting cargo containers or evacuation stretchers.

Four robots, one system

MAT1LDA is part of the Tencore Ecosystem, which brings together four classes of ground robots for military and civilian work, Militarnyi reported earlier. Besides the amphibious eight-wheeler, it includes the tracked TerMIT, the wheeled TOR 4×4, and the TRAX Utility firefighting and rescue robot. The company says it has delivered more than 4,000 robots to Ukraine’s armed forces since the full-scale invasion, used across more than 50 brigades.

Tencore calls it Ukraine’s first integrated ecosystem of its kind. Putting the platforms into one system is meant to make them easier to use, maintain, and fit with extra equipment. One of the first shared add-ons is AI KIT, a hardware and software module that lets a robot keep to its route or drive back on its own after losing contact with its operator.

On show in Washington

Tencore displayed MAT1LDA carrying a TerMIT robot at the Association of the US Army’s annual trade show in Washington this month, Breaking Defense reported.

Other Ukrainian makers have built swimming ground robots too: one switches from land to water in seconds, and another can tow 10 tons, its maker says. In April, Tencore formed a joint venture with France’s Shark Robotics.

Ukraine’s six-wheeled Frodo ground robot fired on targets during a demonstration in Kharkiv Oblast for the Pomsta (Revenge) Border Guard Brigade, a border guard detachment posted on Facebook. Frodo made its public debut only on 30 September.

Ukraine had contracted more than 22,000 ground robots for 2026 by July, mostly logistics carriers, with combat models the smallest group, the Defense Ministry said. Frodo’s first reported mission was an evacuation. The demo shows its armed version to a fighting brigade, the kind of robot Ukraine has ordered least.

What the armed version carries

The platform completed its tasks at a training ground in near-combat conditions, said the 3rd Border Guard Detachment named after Hero of Ukraine Colonel Yevhenii Pikus. The Buria turret mounted on Frodo can fire either a Mk 19 automatic grenade launcher or a Browning M2 heavy machine gun. It engaged targets at up to 1.3 km (0.8 mile), the detachment said.

The 47-kg (104-lb) module has a ballistic calculator, stores up to 256 targets, aims in three seconds, and has a stated autonomous run time of up to 48 hours, the post said. Frodo is rated for up to 150 km (93 miles) on paved roads and 75–80 km (47–50 miles) over rough terrain, the post added. A Frontline Robotics Zoom reconnaissance drone flew reconnaissance during the test.

The developer, Frontline Robotics, describes its core philosophy as arriving fast, doing the job, and leaving very fast—hit and run, the detachment’s post said. Familiarizing the brigade’s soldiers with such systems aims first and foremost to preserve personnel’s lives and health, the detachment said.

A robot first reported as a medevac

Frontline Robotics told Militarnyi at the unveiling that Frodo had passed Defense Ministry codification and was built for logistics, evacuation, and strike missions. The robot reaches 40 km/h (25 mph) and carries up to 200 kg (441 lb) of payload, or 400 kg (882 lb) at most, the company said. A single soldier can swap its batteries.

The 92nd Assault Brigade used an early test unit to evacuate a wounded soldier, Frontline Robotics told Militarnyi. An operator, callsign Tango, named the robot’s speed and its ability to handle complex maneuvers as its main advantages, Militarnyi reported.

Ukraine’s amphibious ground robot UNEX UGV can tow artillery guns, its project lead said in a video interview, Militarnyi reported on 13 October. The electric platform from ABRIS Design Group (ABRIS DG) also swims, climbs, and hauls cargo on its own deck.

The Defense Ministry’s robot tally, kept in its DELTA system, counts supply and evacuation runs. It logged 25,143 of them in August, a monthly figure that has climbed all year. In April, then-Defense Minister Mykhailo Fedorov said the goal was for robots to handle all frontline logistics. A robot that brings a gun and its shells to a position adds artillery moves to that workload.

A gun behind, shells aboard

The robot can pull a gun or another wheeled vehicle of up to 10 metric tons (about 22,000 lb), the project lead said. Ammunition can ride aboard, so the gun and its rounds reach the position together. No crew has to go with them, he said, and the team has already demonstrated the setup. On its own deck, ABRIS DG says, the robot carries up to 1.7 tons (3,750 lb) on land and 1.25 tons (2,760 lb) on water.

ABRIS DG said US Army testers ran UNEX through scenarios that included towing Joint Light Tactical Vehicles (JLTVs), which are armored US military trucks. The trials took place at the Army’s XTech competition in Vilseck, Germany, in March 2026. UNEX was picked as one of five winners, the company said.

Swims, climbs, backtracks

The robot can float for more than an hour. The team has already crossed the Desna River and narrow stretches of the Dnipro with it, the project lead said. Ultra-low-pressure tires spread its weight over soft ground and swamps. ABRIS DG says it climbs obstacles up to one meter (3.3 ft) high and drives out of water onto ice.

Ukraine turned ground robots into a frontline workhorse. Its first competitive tender may reward cheap copies over proven machines, an officer warns

Operators steer it via Starlink or radio. An escort drone can add an overhead view to the robot’s own cameras. If the link drops, the robot retraces its route to where the signal last held.

It runs on a Ukrainian-made 78 kWh battery. The project lead puts its work time at up to six hours and its range at up to 120 km (75 miles), with a top speed of 20 km/h (12 mph). Load and terrain cut into those figures, he added. With a generator now in development, a mission should stretch to about 12–14 hours, he said.

The robot is not built for the zero line, the project lead said. It works 20–30 km behind the front, at night, where armor would add little. Developers also plan demining and air defense versions. Ukraine’s Defense Ministry codified the robot and cleared it for use in its forces in April 2025.

Ukraine has turned ground robots into a frontline workhorse, and the state is now trying to buy them at scale through its first competitive, ministry-spec tender. Viktor Pavlov, an officer of the 3rd Separate Assault Brigade's UGV battalion, laid out the risks of that model to Army Inform, the Defense Ministry's outlet, in an interview. Once a robot clears the military's technical requirements, price becomes the main criterion, Pavlov says. The order is split into lots, and no maker can take more than half a class. He warns the model may not tell a cheap, makeshift machine from one that actually survives at the front.

Robots now handle the war's deadliest chores—driving supplies through kill zones and reaching the wounded where people can't—and Ukraine has already contracted more than 22,000 for 2026. How the military buys them now shapes whether the push yields machines troops trust or a stockpile of cheap ones they don't.

From disposable drones to the next mass weapon

Aerial drones became disposable, mass-produced weapons years ago. Ground robots—the tracked and wheeled machines that haul supplies, pull out the wounded, and attack Russian positions—are only now reaching serial state supply. In August, the Defense Procurement Agency (DOT), the body that buys Ukraine's arms, opened its first competitive tenders for logistics and strike robots built to specs set by the Defense Ministry. Pavlov, founder of Ukraine's UGV School, calls it an experimental format that can work where market prices are inflated. Splitting the order into lots also gives smaller engineering teams a real chance, he said, because many large producers are already busy with state contracts.

Why the lowest bid may beat the best robot

A tender rewards the cheapest product that formally meets the requirements, not the best one, Pavlov said. A thermal camera, for example, can be listed as desirable rather than mandatory, so a maker chasing the lowest price will most likely leave it off. On any given feature the machines diverge—suspension, cameras, comms channels, a winch—one has it, another doesn't, yet both can land in the same class.

The machines themselves are very different. One carries 250 kilograms, another up to 349, but both fall into the "200-plus" category. Unlike FPV drones, which share standard sizes and parts, ground robots have no common frame—Ukraine fields many local variants. Pavlov compared the choice to picking an iPhone over a cheaper Android: on paper the features match, but soldiers know which machine they can run and repair.

He also fears the model punishes innovation. A company can spend 18 months and a 20-person team building a robot, then watch a rival copy it, skip the research costs, and undercut it. A design troops already know how to run and repair—like the Ratel—is a known quantity. An untested bargain can break down mid-mission with no spare parts.

A mixed system, not tenders alone

Price competition should be one tool, not the only one, Pavlov argued. New robots should first reach units through pilot buys, letting soldiers test them and say what works. Proven systems can then be contracted in bulk, with tenders saved for classes where the offers are truly comparable. Ukraine's robots are too varied, he said, and what units need can't always be squeezed onto a spec sheet.
