Please balance the maintenance robot.

In a safe place, I use this equipment to threaten vehicles without leaving my home. First, I place a few landmines behind the vehicle, then, like a terrorist robot, I move under the vehicle and attack it or force it to trigger the landmines. This is a cost-free anti-vehicle behavior. Imagine if I were concentrating on fighting an enemy vehicle and was attacked like this, even being blown up, I would be very frustrated. So I request a balance for the repair robot, or at least I can crush it.
