CONTROL METHOD FOR INDUSTRIAL ROBOT

PURPOSE:To facilitate correction works for a sensing operation and a sensing point by replacing a bit of position information at each teaching point in a manual mode with a bit of teaching position information. CONSTITUTION:In an operation by every step given to a robot RO, when a bit of teaching command position information in the bit of position information of a working line at a work 1 is required to correct because of an individual difference in the work 1, a correction process is performed switching a mode change-over switch SM to a test mode. The correction process is performed in the test mode to the preceding step of a step to be corrected setting the switch SM at the test mode. Next, the switch SM is switched to the manual mode, and a welding torch 4 is moved to a new point position, and also, a linear interpolation is set by a ten-key TK. And the interpolation by a sensor is performed, and an old bit of teaching information is eliminated, and a new bit of position information is written on a memory in CPU 7 (computer).
