At the same time as establishing a means of recording operation data 4, to
record the operation data of robots 2 and 2.multidot. .multidot., monitor
cameras 5 and 5.multidot. .multidot., to film the operation status of
robots 2 and 2.multidot. .multidot., and a means of recording visual data
6 and 6.multidot. .multidot., to record said visual data from said monitor
cameras, a central computer 7 is installed, into which an advisor can
collect both said operation data and said visual data by means of the
Internet N, wherein, if an error occurs in either robot 2 or robot
2.multidot. .multidot., the advisor is able to collect operation data and
visual data from before and after the occurrence of the error into said
central computer 7, analyze both said types of data in order to
investigate the cause of the error, following which, images of the site
filmed by monitor camera 5 can be downloaded by means of the Internet N,
wherein said advisor is able to issue instructions to an on-site operator
