They are the main antagonists of the No Man’s Sky universe. Those retards will proceed to attack you after you try to:
-Get some natural resources near them
-hit them
-Kill creatures
If they’ll start to attack you the best option for a new player is to run away or hide in the ground. If you run away they will seek you for 10 seconds (depends which wanted level you have) and will eventually leave you alone.
Giga chad option: you decide to fuck them up
This method will get harder as you proceed, you will get wanted levels as you progress:
Wanted lvl 1 - armoured drones, healer drones and summoner drones, the 2 last ones have very small health.
Wanted lvl 2 - more of the previously mentioned
Wanted lvl 3 - everything above but a fucking boston dynamics robot aswell
Wanted lvl 4 - a medium mech will enter aswell
Wanted lvl 5 - OH MY GAWD A FUCKING AT-ST WALKER WILL PROCEED TO FIRE LASERS AND ROCKETS (You have to destroy his armour so you can kill this shit)
Alright
In order to win the battle you would have to get a good weapon module for ur multitool. I use the pulse spitter. Its very good if you have 4 more pulse spitter S class upgrade modules which you can get at space stations.
After you kill them all they will be turner off for a long period of time.

Exosuit: SENTINEL DRONES ALERTED
Me without any weapon modules: oh god oh fuck
