Delay getting hit by the Atomic for as long as possible, then fall off the ledge and clip through the first Workrobot. Move partway across the room and keep the Atomic just off screen, which is where Samus can see approximately one full tile of the vertical doorshell. Wait for the Workrobot to appear, then hold right as it enters the screen to get hit by the Atomic and kago through the Workrobot. Quickly use the camera scroll blocks just left of the bomb blocks, in order to overload PLMs and go through them before the Atomic hits Samus.
