PURPOSE: To provide a robot offline teaching system and a robot operation analysis device which allow a robot to work even if there is any difference between work environment represented by an environment model and actual work environment by providing a target state determination program creation part for creating a target state determination program for determining whether or not target state has been achieved based on information from the robot.

CONSTITUTION: A command interpretation part interprets commands which direct a target position for a robot operating point or position as well as mutual target state for the robot operating point and a work target, and an operation program creation part 5 creates a robot operation program for generating a target track which a robot operating point should follow within work environment represented by an environment model based on the results of interpretation and controlling the robot so that the robot operating point can shift its state along the target track. Then, a target state determination program creation part 6 creates a determination program which determines whether or not the target state has been achieved based on information from a sensor in the robot.
