Russia is building ground-based kamikaze robots out of old hoverboards

A Russian group is cobbling together hoverboards, a form of personal transport, to create four-wheeled robots capable of carrying out kamikaze attacks, moving supplies or laying a smokescreen. Both sides in the Russia-Ukraine war are using improvised aerial drones by the thousand, while in the Black Sea, Ukraine has deployed an armada of uncrewed vessels developed from Jet Skis and speedboats. Both sides are also developing cheap ground-based robots, and Russia's latest effort is an extreme example.
