<p>Industrial robot comprising a movable arm (10), a wrist (14) mounted pivotably about an axis (16) at the end of the said arm and a cylindrical shaft (18), perpendicular to the said axis, mounted rotatably at the end of the wrist. In order to be able to be used to hold parts subjected to forces, for example during grinding operations, the robot comprises mechanical brake means comprising, in particular, jaws (46a-b) which can be applied to the shaft (18) and which are capable of preventing both the rotation of the shaft and the pivoting of the wrist (14). <IMAGE></p> |
