Abstract: A transfer robot includes one arm, another arm, and a motor. The one arm has a first connection portion. The other arm has a second connection portion that is connected to the first connection portion of the one arm via a shaft such that the other arm is rotatable relatively with respect to the one arm around a shaft axis of the shaft. The motor is provided inside the first connection portion of the one arm. The motor includes a rotor rotatable around the shaft axis to rotate the one arm or the other arm around the shaft axis.

Abstract: A transfer robot includes one arm, another arm, a motor, and a brake. The another arm is connected to the one arm via a shaft such that the another arm is rotatable relatively with respect to the one arm around a shaft axis of the shaft. The motor includes a rotor rotatable around the shaft axis to rotate the another arm around the shaft axis, and a stator connected to the one arm. The brake is provided at the another arm to apply a force to the stator so as to suppress relative rotation between the stator and the rotor when electric power is not supplied to the motor.
