This attack makes R.O.B. spin around rapidly with outstretched arms. The attack also grants R.O.B a bit of horizontal lift, 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 [[reflection|reflect]] any incoming projectiles that hit the outstretched arms. The move can be a 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 other, faster reflectors. Finally, it can be extended by mashing the special move button. If R.O.B. moves left or right while performing this move, his torso will also bend.

 

In ''[[Super Smash Bros. 4]]'', the move ends with an uppercut that deals increased damage and knockback. The spins also trap enemies more reliably, allowing the entire move to combo well into the final hit. However, the move was still slow and highly punishable, with its KO power being limited.

 

The move was dramatically improved in ''[[Super Smash Bros. Ultimate]]'', where the move now starts more quickly, and is active for less time overall, making the move slightly harder to punish. The KO potential of the finishing blow was increased significantly, making Arm Rotor a devastating KO move when used off stage, especially when directly following up a thrown [[Gyro]] or forward aerial.

 

|ssbudesc=Hops forward with an arm-spinning attack. Can also reflect projectiles.

Special Move customization was added in ''[[Super Smash Bros. 4]]''. These are the variations:

{{CustomSet|ROB|Side|name1=Arm Rotor|desc1=Hop forward with an arm-spinning attack. Can also be used to reflect projectiles.|name2=Reflector Arm|desc2=A longer arm spin that makes it easier to reflect projectiles. No forward movement.|name3=Backward Arm Rotor|desc3=Spin opponents around while knocking them away. Its slow start leaves you open to attacks.}}

# '''Backward Arm Rotor''': Hits less and has an incredibly short spin, but the uppercut comes out much quicker and the move is also able to combo into itself. The attack always leaves opponents facing away from R.O.B. Can stop projectiles and certain attacks. Note that the description says it has a slow start, but it has the same startup as the regular version.

The move is an original creation; however, the spinning animation is similar to R.O.B.'s victory pose in ''{{s|mariowiki|Mario Kart DS}}''. The R.O.B peripheral in real life could also rotate its arms, albeit at a much slower pace than Arm Rotor.
