You can't avoid the flying robot guard. It actually helps you by sending you off to the freezer room, where you can use the wire cutters to disable the security system (cut all three wires, in no particular order). Now you can get the Password from the Printing Room and return to the Processing Room.
(see related question)
Go (back) to the Processing Room to free the drones there. (If you have not been to the Printing Room to get the Password, you can do it on the way.)

All three of them. Once the security system is disabled, you can return to the Processing Room and free the drones there.
when your trapped in the warehouse do you mean caught by the security rabbot (yes, rabbot not rabbit)? if you do, then click the box that says security system. then use the wires found in the air vent to cut all of the wires. next jump all the way to the top and climb back through the air vent.
When you are transported to the freezer, cut the wires on the security system there. (You find wire cutters just before you enter the processing room).

the factory, get the crowbar to open the vent
The wire cutters are in the vent just outside the Processing Room (far right then down in the vent system). You will use them in the Freezer room to cut all the wires of the security alarms.
You go to the printer room and get the system password.
If you are detected by the automatic security in the Processing Room, you will be teleported to the Freezer on the far side of the factory. Since you have picked up the wire cutters in the vent, open the security system wiring box and cut all three wires. Now you can go back to the processing room and free the drones there. (see related question)
The Freezing Room is at the far right bottom of the vent system. There is no need to go there because the wire cutters you need are near the processing Room. Go to the Processing Room and trigger the flying security robot. You will be transported to the Freezing Room where you can disable the security system by cutting the three wires.
If you mean in 24 carrot island, you'll need wire cutters. So if you have them and you're in the frizzier, then click on a box that says, security system and cut the wires. (wire cutters are on you're way to processing room.)
