<p>PURPOSE:To unreasonably pull no substance gripped by a slave arm by displacing the slave arm by following to a master arm with maintaining the positional deviation of the master arm and slave arm, and after releasing the slave arm performing positional setting by opening a shift function switch. CONSTITUTION:A master arm 22 is hung down prior to its actuation and on the other hand a slave arm 14 is taken to grip the substance of an electric wire, etc. In this state, since a control command signal Sc of form the master arm 22 is fed to a servo valve 24 as an operating signal with maintaining the positional deviation of the master arm 22 and slave arm 14 by inputting a shift function switch 38, the slave arm 14 is displaced by following the master arm 22. When the slave arm 14 is thus released from the body of an electric wire, etc., gripped thereby, positional setting is performed by opening the shift function switch 38 and the breakdown of the gripping body by its unreasonable pull is evaded.</p> |
