RobCo facility The RobCo facility is a factory owned by RobCo Industries . It is located slightly northeast of Tenpenny Tower and south west of Fort Independence . The many protectrons scattered across the D . C . area were once manufactured here . Background . Tinker Joe can be found in the parking lot outside the facility along with his robots , including potential companion Sergeant RL - 3 . The parking lot is also a random encounter location . Inhabitants include mole rats , radroaches and protectron s . There are a number of unused protectrons which remain in their charging stations and a few Nuka - Cola vending machine s on the various levels . After installing the mainframe processor , the option to reconfigure the mainframe to stop all the protectrons in the facility from attacking presents itself , as long as the Lone Wanderer has at least 50 Science skill . Once hacked , the mainframe will have a few options : Layout . RobCo factory floor . The first room has five protectrons on display in various positions . Two will be more specialized and in the spotlights : a Nuka - Cola protectron and a military - issued protectron . The other three are standard protectrons . Two rooms on the left are restrooms . To the northwest there ' s a small room with two storage closets with minor loot and ammunition . To the right of the entrance are two paths . The left path going to a room with a few lockers and shelves that then leads to a larger room which seems to be a small part of the assembly line for the robots . To the right from coming through the entrance is a much smaller room with a workbench . After this room are some stairs that lead to overlooking the previous large room . The right path is simply a winding flight of stairs that also leads to overlooking the large room . Offices and cafeteria . When entering this room , there will be two pool tables , with the right one having a couch on top of it . There are two Nuka - Cola fridges , and one regular refrigerator to the right . If heading to the left from this room , there will be a long hallway . Going through the hallway there should be a mannequin , along with three ammunition boxes . A little further down , there ' s a gate with a leaf blower and two lawn mower blades . Right before the hallway ends there is a room to the left . In there is a first aid box and not much else . Going straight from the first room is a small cafeteria with four tables on the right . Continuing from this room one can go straight or turn left . To the left and another left there is a small room where the first hallway ended and past that there is another room with minor caps and loot . Turning left and then going straight leads upstairs . If heading right from the original room , there will be a short hallway with restrooms on either side . Past that there is the office with four office spaces with minor loot . From there there ' s a hallway with three rooms on the sides . The first looks like an office / storage area . The second room is a larger office with four desks and file cabinets . The last room is again an office / storage area with several boxes and a first aid box . Now continuing upstairs it makes like a trident pattern . The left path there ' s a storage closet and past that is a small monitor room with two lockers . The right path is the same but a bit more destroyed . The storage closet is caved in and the monitor room messed up . Lastly , continuing straight from the stairs is the main computer room for the whole building . There ' s a first aid box , a pre - War book , and a Stealth Boy in there . Appearances . RobCo facility appears only in " Fallout 3 " . Bugs . Immediately after entering the door to the cafeteria area from the factory floor , you ' ll notice , in the pod to the left , that the protectron ' s arms slowly move down to its sides , even though it ' s supposed to be deactivated .
