Arm Rotor (アームスピン, Āmu Supin Arm Spin) is R.O.B.'s side special move. The attack causes R.O.B. to spin with an arm outstretched. The attack also lifts R.O.B. into the air slightly, allowing it to be used to aid R.O.B.'s recovery a bit (though this is rarely necessary). It deals minor damage (normally 4%), hits multiple times and has decent stun and knockback. This attack can also reflect any incoming projectiles that hit the outstretched arms. The move can be bit difficult to use as a reflector, as there is bit of delay before R.O.B. starts to spin his arms, thus requiring more accurate timing than the other faster reflectors. Finally, it can be extended by rapidly tapping the special move button. If R.O.B. moves left or right while performing this move, his torso will also bend.
The move ends with an uppercut that deals increased damage and knockback in Super Smash Bros. 4.
Customization
In Super Smash Bros. 4, Arm Rotor has two custom variants - Power Spin and Quick Spin. Power Spin halves the duration of the spin, but increases the damage and knockback, and also replaces the move's multi-hit properties with a single hit. It also reflects projectiles with a 1.8x damage multiplier. Quick Spin has the shortest spin duration among all three moves, but the uppercut comes out much quicker and the move is also able to combo into itself.

Origin
The move is an original creation, however the spinning animation is similar to R.O.B.'s victory pose in Mario Kart DS.
