๐ฅ In Ukraine, a kamikaze ground robot was created for the Armed Forces: how it is used by the military
Brave1 developers have created a new technology for the Ukrainian military - the ground-based kamikaze robot Ratel S. It allows you to hit enemy targets from a safe distance.
This kamikaze robot is capable of carrying anti-tank mines or a combat module at a speed of 24 km/h. In addition, it can travel a distance of 6 km and remotely blow up an enemy tank or dugout.
Weight isn't as much of a consideration for a ground based unit, so you can have a bigger boom. I don't know if that's really required, but it could be useful for clearing entrenched positions.
For armor, the least armored location is usually (pretty much always, maybe with some weird exception) on the bottom. If you can drive under it, especially with a bigger explosive, even the most heavily armored vehicle is toast.
That said, you do need to reach it which will be harder on the ground obviously. It will be interesting to see how useful it'll be. If it's cheaper or similarly priced to an airial drone, I'm sure it'll come in handy. It'd be a cool bonus if it can deploy its payload and leave before detonating it and be recovered, but I'm assuming that isn't an option.
