American firm AZAK has introduced a ground‑based unmanned vehicle (UGV) that successfully knocked down a U.S. Army logistics truck weighing more than 24 tons and carrying roughly 450 kg of munitions. The robot itself weighs just 227 kg but can lift loads over 100 times its own weight. Its high‑torque capability comes from a design that places the motor, battery, gearbox and control system inside each wheel, allowing each wheel to drive independently. The U.S. Army is evaluating the technology for “last‑mile tactical” missions, such as moving ammunition, supplies, and evacuating wounded soldiers from near‑front‑line areas without exposing personnel to enemy fire.
