A servo control apparatus and method, the servo control apparatus including an input unit configured to receive an execution command with respect to one of a first control mode and a second control mode that are configured to control a motor, a plurality of detection units each configured to detect sensing data required for executing each of the first control mode and the second control mode, and a control unit configured to receive a feedback of the plurality of pieces of sensing data detected through the plurality of detection units while executing the first control mode, determine a point of time when a control mode is needed to be changed if the execution command with respect to the second control mode is input through the input unit, and check the sensing data required for executing the second control mode among the plurality of sensing data that are fed back.

Servo control apparatus and method for controlling the same

A robot which is able to complete all or a part of desired operations and take a safety countermeasure in order to prevent an unexpected result from being obtained, even when a power source of a motor-based robot is unintentionally and suddenly cut off. A method of controlling a robot, which includes a main power source, a subsidiary power source and a motor to receive power from at least one of the main power source and the subsidiary power source, includes driving the motor using power supplied from the subsidiary power source if power supplied from the main power source is cut off, selecting at least one of a plurality of safety control modes to stably control the robot in consideration of a current state of the robot, and controlling the robot to operate in the selected safety control mode.
