Robot with a lot of heart

Does anyone have some tips and tricks for how to get this achivement or is it just plain luck? My drones are never low on health when returning and I only send out one through out the whole cave so that I´ll know it has full cargo upon returning.

I was very lucky yesterday: I already got the hint to use aMagnetic Drone as the inventary is always fulland then I useed the strategy tostay on a lava field to pull an object from a an attached field. And 2 or 3 radioactive fields did the rest :)
So firstcheck how much you lose when passing a lava or radioactive field and then calculate andhave some luck :D

I had been trying with the Basic Drone and gave up... saw I earned it a couple of days ago and was ???? but must have accidentally done it with a MD.

I did it with a lvl3 basic drone and 85% speed bonus from relics
1st I waited for a lava field near the entrance and sent the basic drone to collect 3 treasures
2nd I sent out a magnetic drone to pull 1 treasure into the lava
3rd I sent a healing drone to heal the basic drone back to 290 life before it reached the lava field again
The basic drone dropped down to 14 hp.
