Mining droids are the most basic and weakest of the Rovers. They don't do too much damage, although their attack is most effective against other Rovers. It is recommended to use them in groups in order to deal noticeable damage. Contrary to the in-game description, they are fairly short-ranged compared to most other units.
The main upside of Mining Droids is how easily they are mass produced. They're cheap, quick to build, and don't take up much unit space.

Mining Droids seem to be based on Sojourner, one of the first rovers to be sent to Mars.
