The robot control apparatus, which judges the restart an operation program

A robot control device includes a stop command unit that stops a robot. A first evaluation value of an external force, which is less than a stop judgment value, and a second evaluation value of the external force which is smaller than the first judgment value of the external force, are determined in advance. The stop command unit prohibits a restart of the execution of an operation program, when, in a state in which the execution of the operation program is temporarily stopped, an external force is continuously equal to or smaller than the first judgment value of the external force during a period of a first time period, and Moreover, the external force continuously exceeds the second judging value of the external force during a period of a second period of time.
