Abstract
A transmission coupling for manipulator head includes a support body (50) connected to the manipulator head (4), an intermediate transmission member (76) slidable on the support body (50) along a first line (C), and an attachment member (28) slidable on the intermediate member (76) along a second line (B) perpendicular to the first line. The attachment member can pivot relative to the support body (50) about at least two mutually-perpendicular axes substantially parallel to the plane defined by the first and second lines. The present invention also relates to a rapid attachment device for an interchangeable tool for a manipulator head (104) including a base body (106) connected to the manipulator head and a generating device for providing a force for retaining the tool (102). The base body and the tool have respective cooperating abutment surfaces which are kept in contact as a result of the force exerted by the generating device and are adapted to establish the position of the tool relative to the head along a first line of constraint. Constraining members (118, 120) are provided for constraining the two degrees of freedom of the tool in a plane substantially perpendicular to the first line of constraint.
