A measuring apparatus having multi-joint for manufacturing adjustment tube

The present invention relates to a measuring device having multiple joints. The measuring device includes a joint row in which a plurality of joints including motors having encoders are connected in series by links; a first jig connected to a first joint of the joint row; a second jig connected to a second joint of the joint row; and a computation part which computes a location relation between the first jig and the second jig based on the value measured by the encoder and the length of the link.
