  • TRANSFER ROBOT AND ROBOT SYSTEM
    Publication number: 20220001541
    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.
