Abstract: Disclosed herein are a motor safety control method that can efficiently detect an abnormality of a motor sensor configured to sense a rotational motion of a motor and control a safety operation of the motor based thereon, and a robot for implementing the method. The motor safety control method for a robot may include receiving a first motor value from a high-resolution sensor of a motor, receiving a second motor value from a low-resolution sensor of the motor, and comparing a threshold with a difference between the first motor value and the second motor value, and transmitting an operation signal to a motor driver for the motor to continue or stop operation of the motor.
