Robot program production system

A robot program production system comprising 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, a work to be processed by the robot, and obstacles to a process performed by the robot, a programming unit that produces off-line in advance a robot program which instructs the robot to perform a series of actions, and a robot control unit that controls the action of the robot so as to move the robot to a teaching point, wherein:

• the programming unit includes a means for determining a path, along which the robot is moved from the current position of the robot to a teaching point, which should be corrected, without interference with the work to be processed and the obstacles to the process, on the basis of the pieces of information on teaching points described in the robot program produced in advance and the information on the ambient environment model;
• and
• the robot control unit includes a means for moving the robot to the teaching point, which should be corrected, along a determined path, and replaces the information on the teaching point, which should be corrected, with information on an actual teaching point acquired after completion of the movement so as to thus correct the information on the teaching point described in the robot program.
