Airless wheels Ukraine robots keep battlefield bots rolling

Ukrainian researchers have completed battlefield testing of inflation-free, 3D-printed wheels for unmanned ground vehicles. The wheels are designed to remove the need for air pressure entirely, aiming to keep robotic platforms moving after damage on the front lines.

Developed by Print&Live UA, iSCALE 3D and participating specialists, the wheels use large-scale 3D printing to create a closed, lattice-based interior and a rounded tread. The approach replaces traditional pneumatic tires with a durable, pressure-free design that resists punctures and blast effects, which are common on modern battlefields.

Weights for the wheel sets range from 32 kg to 56 kg, with conventional pneumatic sets typically in the 30 kg to 72 kg range. Designers say the airless design can still reduce energy demands and rolling resistance due to its lighter, more compact internal structure and curved tread geometry.

One key benefit highlighted by the team is ease of field servicing. The two-piece rim design allows damaged tires to be installed or replaced without the specialized presses usually required for traditional tires. This could be especially valuable for frontline repair teams working in limited conditions.

Independent field data is still forthcoming, but the developers claim the wheel set could extend a robot’s operating distance by as much as 30% compared with some foreign airless options. The complete wheel set is quoted at about €680, though the announcement notes the price may vary depending on configuration and replacement parts.

For readers, what matters is what this could mean for ordinary users who rely on robotics and remote sensing on the frontline or in industrial settings. Inflation-free wheels can keep mobile robots moving even when damage prevents tire inflation or when terrain makes punctures likely. In practical terms, that could translate to longer mission time between maintenance, lower downtime for repairs, and fewer trips to service depots.
