A robot program production system includes: a storage block that saves pieces of information on teaching points to be taught to a robot and information on an ambient environment model representing the robot and others; a programming unit that produces off-line a robot program; and a robot control unit that controls the action of the robot so as to move the robot to a teaching point. The programming unit includes a means for determining a path, along which the robot is moved from the current position to a teaching point, which should be corrected, without interference with a work and obstacles, on the basis of the pieces of information on teaching points and the information on the ambient environment model. The robot control unit includes a means for moving the robot to the teaching point, which should be corrected, along the determined path. Information on the teaching point that should be corrected is replaced with information on an actual teaching point acquired after completion of the movement, whereby the information on the teaching point described in the robot program is corrected quickly. This results in a program capable of protecting the robot and ambient facilities from being damaged.
