Screwbot Factory

"Robot assembly is a precise task. You'll need to tighten the final screw just the right amount."

- Screwbot Factory Description (US version)

Screwbot Factory (ロボット工場 robotto koujou lit. robot factory) is the second game on Rhythm Heaven Fever. It features headless, lifeless bots called Screwbots that move along a conveyor belt and need to be built. The sequel Screwbot Factory 2 appears later during game progression and is the eighth sequel to be unlocked. Getting a Perfect on this game rewards the player with the Screwbot Factory soundtrack. It's also an Extra Game unlocked in Rhythm Heaven Megamix that can be bought for 4 Flow Balls in the shop in which its japanese name has been changed to Robot Factory Screw.

Gameplay
The object of the game is to re-attatch a screwbot's head onto their bodies the correct way through rhythm. Screwing them on too tight or not enough will not make them function properly. The robot arm cues vary but is usually four beats longs, it grabs a robot on the first and and places it on the fourth. Occasionally, the cue will be only three-beats long where the robot is dropped on the third beat, particularly on consecutive robots. White robots make an additional whistling cue when being lifted by the arm. The claw must grab the robot one beat after it has been placed and must be released three beats after for grey robots and two beats after for white robots.

In Megamix, the controls of this game were changed to use just A button instead of using B together.

Timing Notes

 * Hit: Grabbing a robots' head in time will cause the claw to start screwing immediately. Releasing at the right time will cause the robot raise its arms and for a heart to light up on it's body; this happens regardless whether the robot was grabbed in time or barely. It will also shout "Oh yeah!" for grey robots, or "Let's go!" for white robots.
 * Barely: Barely grabbing the robot with the claw causes a popping sound to be made, and will briefly drag the robot towards the claw before it starts screwing. Releasing the claw bit too early makes it stick a sideways position, with the robot frowning. Screwing on a bit too much causes the robot's body to crack, sending it down the conveyor belt with blank white eyes and a dazed stance.
 * Miss: Missing the robot's head entirely causes it to go by on the conveyor belt. Hitting it too early or late causes it to fall over. Barely screwing on the robot's head causes it to fall over. Screwing the head on way too much causes the body to lift up and start turning, eventually sending the broken robot down the conveyor belt as it fall over. Releasing only A or B knocks the robot to the right or left, respectively, leaving it only partially screwed.

Trivia

 * Screwbot Factory greatly resembles the game Fillbots from Rhythm Heaven.
 * This is the only game in Rhythm Heaven Fever that gives a unique response when pressing the B button by itself.
 * In the Japanese version, there is an engraving on the robot arm that brings up the Screwbots to the conveyor belt that said "Safety first" (安全第一). This was removed in the English version.
 * Dead robots are on the Try Again Rating Screen.
 * In Rhythm Heaven Megamix, The Rhythm Game's japanese title was changed to Robot Factory: Screw (Japanese: ロボット工場ネジ) due to the DS version being included with the same title that became Robot Factory: Oil.
