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.

Abstract: A robot may perform emergency stopping. The robot includes: a driving device configured to perform movement of the robot; a stop switch configured to output a stop switch signal; a controller configured to output a stop signal; and a stop circuit configured to output a first control signal and a second control signal for stopping the driving device. The stop circuit may output the first control signal and the second control signal in response to the stop signal and the stop switch signal.

Abstract: A robot control device for a robot comprises a case and a connector board which is coupled to the case and includes a plurality of connectors which are disposed in a first region and a second region adjacent laterally to the first region. The plurality of the connectors may comprise a power connector which is disposed at a bottom of one of the first region or the second region and is coupled with a power supplier; and a processor connector which is disposed in a region different from that of the power supplier and is coupled with a processor.
