Abstract: A method of planning works for robots includes creating a work plan for a plurality of robots, each having a work tool, sharing at at least one station a work to a plurality of work parts of the workpiece. The method includes the steps of calculating a distribution of the work parts to the robots, calculating, as a robot operation, a work order of the work parts and a moving path of the work tool for each of the robots based on the calculated work distribution, and calculating a disposed location of each of the robots with respect to the workpiece and a station where the robot is disposed so that an inter-robot interference does not occur during execution of the calculated robot operation.

Abstract: An offline programming device includes an input unit that receives input of a plurality of teaching points, a creation unit that determines intermediate point located between adjacent teaching points and creates an operation program for the robot, a simulation unit that simulates a movement trajectory of the robot when the operation program is executed, and a display unit that displays a GUI screen representing the movement trajectory. The GUI screen includes a first display area showing a time series sequence of the plurality of teaching points and a second display area. When an error is detected in the movement trajectory, a section between the teaching points including the point in time when the error occurs is displayed in the first display area according to a first error display method.
