Abstract
A fixed point for confirmation is photographed by a camera prior to the start of a robot job, to obtain photographing data (S1, S2), a position data is determined from the photographing data (S3), and an error (.DELTA..epsilon.) between the position data and a reference position data (S4) is determined. When this error (.DELTA..epsilon.) exceeds a predetermined tolerance (.epsilon.a), a camera positional dislocation alarm is issued (S6). With this arrangement, the positional dislocation of the camera can be confirmed prior to the start of a job, whereby the job can be safely carried out.
