Robot control device having operation route simulation function

A robot controller having a function of simulating a motion path of a robot, comprising:

• means for storing a first and a second operation program,
• means for performing a playback operation of said first operation program,
• path memory means for storing data indicative of a first motion path described in said first operation program including data indicative of an interpolation point when said first operation program is played back,
• means for performing a playback operation of the second operation program so that said robot does not perform a real motion,
• path comparison means for comparing data indicative of a second motion path described in said second operation program with said data indicative of said first motion path when the second operation program is played back,
• evaluating means for evaluating a difference between said second motion path and said first motion path, and
• output means for outputting result of the evaluation by said evaluating means.

A method of simulating motion path of a robot controller, comprising:

• storing a first and a second operation program;
• playing back said first operation program;
• storing data of a first motion path corresponding to said first operation program;
• playing back the second operation program;
• comparing data of second motion path corresponding to said second operation program with said data of said first motion path when the second operation program is played back;
• and
• outputting a result indicating differences between said first motion path and said second motion path.
