Overview:
This esp-free file restores the fatigue level of any robot-type creature to max on every hit, to ensure that they aren't knocked out.

If you don't have a mod which overhauls fatigue damage, you can knock robots out with weapons which deal fatigue damage.
If a single hit performs a complete 0-100% knockout in one hit will still result in the robot being knocked out, although their fatigue will be instantly restored and they'll get up right away.

Any decent scripted fatigue overhaul should be excluding robots anyway, so if you use a mod like that, you probably don't need this.

Requirements:
JIP LN, xNVSE, Johnny, ShowOff, the usual stuff.

OWB is required. If you would like to alter the script to function without OWB, simply change the line
if (GetCreatureType rSmacked == 6) || (rSmacked.GetInFaction RobotFaction == 1) || (rSmacked.GetInFaction NVDLC03RobotFaction == 1) 
to 
if (GetCreatureType rSmacked == 6) || (rSmacked.GetInFaction RobotFaction == 1)

Installation:
Regular installation.
Please endorse and vote if you appreciate the mod.

Compatibility:
Compatible with any mod added robots that are either marked as robot in their creature type field, or in the robot faction.

Permissions:
Do whatever.
