Abstract

An operation line searching method in which an operation start position is automatically approached and a robot/sensor system having such function of detecting the operation line. A robot having a laser sensor and an operation tool attached to a distal end thereof approaches an operation start position Q1 using various searching motion path patterns (a) to (d). Pattern (a) is determined to avoid an obstacle F or an obstructively-shaped portion G. The path thereof, for example, can be determined by specifying a coordinate axis of a coordinate system w. Patterns (b) and (c) are carried out by teaching, to the robot, data for determining the paths thereof in order. Pattern (d) is carried out in the following manner: an initial parameter , an angle of rotation and a norm increase factor are specified as parameters, and at the time when incremental travel quantity of a (i+1)th occurrence (i=0, 1, 2, . . . ) Should be obtained, it is obtained by calculating -, where the vector is obtained from the last obtained vector based on the illustrated relationship (the angle of rotation and the norm growth factor).
