Abstract: A robot includes a hand motor configured to independently rotate a first hand and a second hand around a hand axis along a vertical orientation. The hand motor includes: a first output shaft fixed to the first hand; a first stator configured to apply a rotating magnetic field on the first output shaft in the arm link; a second output shaft extending through the first output shaft and fixed to the second hand; a second stator configured to apply a rotating magnetic field on the second output shaft in the arm link; a first bearing held by the arm link and holding the first output shaft or the second output shaft; and a second bearing held by the second output shaft between an outer periphery of the second output shaft and an inner periphery of the first output shaft.
