<p>A method of controlling an industrial robot along an arc wherein the position of a working member attached to the wrist of the industrial robot is controlled along an arc by interpolation, while the angle of the working member with respect to a surface being worked is controlled. The method comprises the steps of obtaining corresponding points (P1, P2 ...: Q1, Q2 ...) of the far end and near end of the working member (TC) attached to the wrist (HD) of the robot at a plurality of instruction points, for controlling the far end of the working member (TC) along an arc; obtaining interpolation points of the far end and near end of the working member from interpolation using the pairs of corresponding points; and obtaining command quantities for the operational axes of the robot from both interpolation points. </p> |
