Father by Ray Nayler

Father by Ray Nayler (Asimov’s SF, July-August 2020) is set in an alternate 1950s America,1 and begins with the narrator of the story, a young boy, answering the door to find that the Veterans Administration have sent his mother a robotic “father unit”; it starts to perform that role for the boy (whose real father died in the Afterwar—the invasion of the Soviet Union after WWII) by pitching baseballs to him.
Later on, after some more robot-boy bonding, a local delinquent called Archie—who has previously verbally abused the narrator, mother and robot—does a low-level fly-by in his aircar and hits father with a baseball bat:

We ran out of the house in time to see Archie’s hot rod arcing off into the sky, wobbling dangerously from side to side on its aftermarket stabilizers.
There were four or five faces sticking out of it. Laughing faces: a girl in red lipstick with her hair up in a kerchief, and the hard, narrow greaser faces of Archie’s friends. As the hot rod zipped off one of them yelled: “Home run!” and hooted, the sound doppling off in the crickety night as they lurched away against the stars.
Father was laying on the ground. His head was dented, and one of his eyes had gone dark. As we came over to him, he was already getting up to his feet.
“Are you all right, Father?” I said.
He swung around to look at me. It was awful—his dented head, the one eye snuffed out. But the other one glowed, warm as a kitchen window from home when you’re hungry for dinner.
“That’s the first time you called me Father,” he said. “I couldn’t possibly feel better, hearing that word from my boy.”
“We should call the cops,” my mom said.
“I doubt they’ll do much,” Father said. “And that young man and his friends really have trouble enough as it is. I feel none of them are headed toward a good end.”
“I’ve said the same myself, many times,” Mom said. She was rubbing a dirty mark off of Father’s head with a kitchen cloth. “What did they get you with?”
“A baseball bat, I’m afraid.” He paused. “Perhaps they mistook me for a mailbox.”
“Hilarious,” Mom said.
“I’m here all week, folks . . .” Father’s bad eye flickered back to life for a moment, then went dead again.  p. 49

The rest of the story largely develops around Archie’s continued persecution of the family, which includes the house getting bricked from the air when the father-robot and the narrator are out trick-or-treating (although the next time Archie flies over, the robot throws a hammer at him and hits him in the face). During this period there are also a couple of visits by an ex-military repairman, the first time to fix the robot’s head and the second time to visit the narrator’s mother. On the latter occasion the repairman says something vague that suggests that father-robot may be partially or all of Archie’s real father and, re the hammer attack by the robot on Archie, something about malfunctioning “sub-routines”.
The final part of the tale (spoiler) involves Archie supposedly making peace with the narrator by taking him to Woolworths for a milk shake—while the rest of his gang lure the robot out of town and attack and kill it (but not before the robot gets one of them). The repairman appears again at the narrator’s house in the aftermath of this event, discusses with another military man the robot’s lethal behaviour, and then what the pair did in the war (which includes a mention of their sub-routines).
The bulk of this story, with its small town America, father-robots, air-cars, and amateur rocket fields, has a likeable Bradburyesque vibe. That said, the later material about the robot’s true identity and its sub-routines is never adequately resolved, and it almost unravels the last part of the story. A pity—if this had continued in the same vein as it started, it would have been a pretty good piece rather than a near-miss.
