An idea: RC sized electric car that can deliver a tank mine under the tread of a tank.

implementation: Using cheap, off the shelf parts: raspberry Pi (such as this one in the post), camera, GPS...

It allows operator to choose a tank target and then this bot self-drives in front of a track.

The only way a tank mine can detonate is if a tank rolls over it. So as long as you are not a tank.. this little bot would be pretty safe.

Would possibly be a game changer for the ukraine war if these could be made en masse cheaply.
