Professor Goodfeels

Professor Goodfeels is a character appearing in Fallout 4.

Background
Found by two men, Jack and Allen, the Mister Handy robot was being reprogrammed to be "free from slavery". Now scouting the area around Sunshine Tidings co-op, Professor Goodfeels can be reprogrammed by the player character to perform various actions. For reasons unknown, this Mister Handy is in poor condition, with his exterior being rusty and dented with pieces of its casing missing.

Effects of player's actions
The Sole Survivor can re-program Goodfeels by using the terminal inside the main building.

Jack and Allen have programmed a "Just Be" mode, in which Goodfeels will simply wander the area and say things such as, "Whoa, man", "Groovy", and "Far Out!" After hacking the terminal in the main building, the player character can reprogram Goodfeels to either guard them in the area or "report back for repairs". Choosing this option adds the area Hesters Consumer Robotics to the player character's map. The Sole Survivor does not have to have Goodfeels travel to the area in order to receive the location on the map.

One can also choose to shut down Goodfeels. Doing so will cause him to simply stop in the area he's in and go dormant.

If player character leaves the location he can disappear. But he will be in game just in disabled state. You can bring him back if you want with console commands.

Appearances
Professor Goodfeels appears only in Fallout 4.

Behind the scenes

 * Also when set to 'Guard Protocols' he will continually repeat the word Exterminate (he drops the 't' at the end) as he follows. This is possibly a reference to the Daleks who infamously use the same word in the British TV show Doctor Who.
 * Professor Goodfeels is a reference to the Motley Crue song Doctor Feelgood.

Bugs
It appears the only way to ensure he remains at Sunshine Tidings co-op is to either set him to 'Just Be' hippy mode or 'Deactivate' him. Uncertain whether this is intended behavior or not as there is no way to interact with him like a companion. Trying to leave on foot he follows for some distance then seemingly returns. Only to suddenly teleport to the player character which is unsettling. Fast travelling away and back he seems to despawn (a noted bug).
