Tiny AZAK robot hauled a military truck 100 times its own weight

[00:00:00]Tiny Aakk robot hauled a military truck 100 times its own weight. Picture a robot you could carry up a flight of stairs, remotely towing a military truck that outweighs a fully loaded school bus and doing it without breaking a wheel.

[00:00:14]That is the scene an American robotics company says it captured on video from a recent US Army demonstration. And if the footage holds up, it says something striking about where battlefield logistics are headed. The company behind the video is AAK, a Denver-based defense technology firm that posted the clip describing a 500 lb unmanned ground vehicle towing a palletized load system truck, the US Army's primary heavy hauler for ammunition and supplies, which the company says weighs 53,000 lb, 24,040 kg empty. That figure lines up closely with published specifications for the Army's PLSA1 model listed by its manufacturer Oshkosh Defense at a curb weight of 53,000 lb before any cargo goes on board. In the video, the small robot is also hauling an extra 1,000 lb 454 kg of ammunition at the same time, meaning the tiny machine is moving more than 100 times its own weight in raw towing capacity. According to Isach's own numbers, the math seems impossible, as Zach wrote in the post. The footage from a recent army demonstration event says otherwise. Understanding why this matters starts with what a palletized load system truck actually is. Built by Oshkosh Defense, the PLS is the backbone of how the Army moves ammunition and supplies to the front. a five- axle truck that can load and unload standardized cargo pallets on its own using a hydraulic arm without needing a forklift or a crew of soldiers standing around. It has been in service since 1993 and has hauled supplies through Bosnia, Kosovo, Iraq, and Afghanistan.

[00:01:54]Getting a machine that size to move at all, let alone getting it towed by something a soldier could pick up with both hands, is not something that happens by accident. That is where Zach's design philosophy comes in. and it looks nothing like a typical military robot. Instead of building a vehicle with a chassis, axles, and a central engine, AZAC puts the entire propulsion system, motor, battery, gearbox, and control electronics inside each individual wheel. The company calls its will module the S26, roughly 26 in 66 cm in diameter and weighing about 86 lb 39 kg on its own, capable of producing around 47 pound- feet of torque per wheel. Because each wheel is a self-contained power unit, AZ can bolt four, six, or more of them onto almost any frame, even a wooden log in past company demonstrations. And the torque scales up with every wheel added. A four-wheel configuration is rated to haul up to 1,500 lb, 680 kg of payload, which starts to explain how a robot in that weight class could get real traction against a stalled multiton truck. A Zach frames the video as proof that the machine performs outside a sanitized lab setting, not inside one.

[00:03:12]Notice the large bump in the video, the company wrote. This isn't a controlled lab test on a flat floor. This is a 53,000 lbs dead weight hitting real world resistance and the AK didn't flinch. What is independently verifiable is that AK has been steadily working its way into the Army's unmanned ground vehicle pipeline over the past year. The company took part in a full training rotation at the National Training Center with the Army's first cavalry division in 2025, testing its platform on terrain where conventional vehicles struggled or could not go at all. It won the Army's Extrike Ground Competition, a program built to find promising new tactical technologies, and it joined GTA, a marketplace designed to connect military buyers with emerging tech suppliers. In March 2026, Azac brought a second generation version of its platform to the A USA Global Force Symposium in Huntsville, Alabama, one of the Army's biggest annual showcases for ground vehicle innovation. None of that guarantees the towing video shows exactly what ak claims, but it to show a company that has spent real time in front of army evaluators rather than only posting demo footage online. The bigger picture here is the problem the army is actually trying to solve.

[00:04:30]Something the service has started calling the last tactical mile the final most dangerous stretch of ground between a supply point and frontline troops where enemy drones and artillery make every truck run a gamble. The Army has already tested other autonomous haulers for this job, including a six- wheeled robot called Hunterwolf used by the 101st Airborne Division to move cargo during a training exercise earlier this year. And it has an open request out to industry for ground robots that can both carry cargo and evacuate wounded soldiers without worsening their injuries. A robot that is small enough to hide, light enough to carry, and strong enough to move a stuck multiton truck would check a lot of boxes for commanders trying to keep soldiers away from that stretch of road in the first place.
