Crow's room is a portion of the SOL occupied by Crow T. Robot.
Crow keeps his possessions in his room, including a television set that he loots when the power goes out (slyly claiming that he'll never miss it). Crow has also mentioned that he has a blender ripe for the looting in his room (which may be the same one that Tom Servo flirted with in the first season).
It may be too that Crow has decorated his bedroom with a Schmidt beer sign and his prized chicken puppet.
