Abstract:
A robot movement programming method for creating a program for moving a robot along a movement path using an information processing device, said method comprising:creating at least one sample program for defining a plurality of sequence patterns of movement of the robot for at least one sample workpiece; preparing conversion formulas as mathematical functions representing geometric figures for obtaining position data of teaching points of the at least one sample program, said conversion formulas including geometric quantities of said sample workpiece as dimension variables such that movement data for multiple workpieces with the same or common shapes but differing geometric dimensions can be determined by changing values of the dimension variables, to define a movement path for the sample workpiece; registering the at least one sample program and conversion formulas for one of the plurality of sequence patterns in a pattern library; changing dimension variable values in said conversion formula for the one sequence pattern for a new workpiece of the same or common shape but having different geometric dimensions; calculating teaching point position data for the movement sequence determined by software means based on said conversion formula for the sequence pattern and said changed dimension variables for said new workpiece; and obtaining a robot movement program based on said calculated teaching point position data for said new workpiece.
