Buddy Drinkin ' Buddy , also called Buddy , is a modified protectron , located in the basement of the Shamrock Taphouse in 2287 . Background . The owner of the Shamrock Taphouse , Patrick Merryweather , was contracted by the Hotel Rexford to design and manufacture a specialized brewing robot capable of producing beer at an accelerated rate , with the intent of serving ice cold beer to hotel patrons . To build the robot , the entrepreneur purchased a consumer RobCo protectron . He stripped out the robot ' s main assembly and replaced it with a custom miniaturized microbrewing unit fabricated with unlicensed parts that was capable of flash - fermenting mash , in turn producing alcohol quickly . In doing so , he voided the robot ' s warranty as the modification was not authorized by the manufacturers . He designed the robot to accept recipe holotapes thus allowing it to brew a wide range of different types of beer , also programming in a wide variety of jokes to be told for the customer ' s amusement . Unfortunately the Hotel Rexford was under contractual obligations to only serve Gwinnett beer . As a result , Patrick was unable to use his own recipes . However , he managed to get in contact with a person who was able to illegally crack the encryption on one of the brewery ' s proprietary brewing holotapes . This allowed the robot to produce Gwinnett pale ale by default . After days of tinkering and perfecting , Patrick managed to finish the robot . He had no respect for copyright considering the recipe holotapes and the unlicensed microbrewing equipment and modifications , but he was able to complete the robot before the Gwinnett Brewery ' s lawyers caught up with him . The final product was Drinkin ' Buddy - the ultimate automated drinking experience . He designed the robot to be ready for mass - production with the main customers being bars and restaurants . Patrick had the original prototype unit scheduled for delivery via truck to the Hotel Rexford . Unfortunately this was cut short by the Great War , leaving Buddy still inactive in his charging pod , his delivery 210 years behind schedule . Character overview . He can be given holotapes containing alcohol recipes that he will store in his inventory . He can also change regular beers and soft drinks into their ice cold variants granting 35 AP in addition to the usual STR / CHR + 1 , INT - 1 ; this is done by following the dialogue option to request a beer , but instead placing drinks into his inventory . Alternatively , the recipes may also be removed just by trying to talk to him . Drinks that one can give to him to make ice cold are any Gwinnett beverage , any Nuka - Cola and any Vim . Brewing . Giving Buddy any " Gwinnett , " " Nuka " or " Vim " will cause it to become ice cold after about 12 hours in - game time . This increases the benefits of the item upon consumption by a variable amount but does not remove the rads present in the beverage . Buddy cannot make generic beer ice cold . To give Buddy recipes , one must play the recipe holotape on their Pip - Boy . Once this is done , the Sole Survivor automatically initiates dialogue by stating " Buddy , I have some recipes for ya . . . , " after which they are removed from the inventory and Buddy will be able to produce them in the future . If this dialogue doesn ' t trigger when speaking to him with a recipe in one ' s inventory , try dropping the recipe from the inventory and picking it up again . This especially helps with recipes obtained prior to meeting Buddy . Combat . Buddy is equipped with a flamer and a laser gun . Buddy alternates between them when in combat .
