First Claim
1. A parallel-type displacement device, comprising:
- at least three arms each pivoting about a pivot axis, the pivot axes defining a polygon as seen from a point above said device,wherein each of the arms is actuated by an actuator and each said arm is further connected to a head defining a small base through linking members respectively articulated on the head and on the arms,each said arm and its respective head forming a hinge having two degrees of freedom such that the head always maintains its position and orientation,wherein in a neutral position, each arm is arranged so that, if drawing from the geometrical centre of the polygon a straight line which is parallel to the pivot axis of any one of the arms, said straight line intersects the arm considered.

Abstract
A parallel-type displacement device having at least three arms each pivoting about a pivot axis, the pivot axes defining a polygon as seen from a point above the device, wherein each of the arms is actuated by an actuator and each of the arms is further connected to a head defining a small base through linking members respectively articulated on the head and the arm, each said arm and its respective head forming a hinge having two degrees of freedom such that the head always maintains its position and orientation, and in which in a neutral position, each arm is arranged so that, if drawing from the geometrical centre of the polygon a straight line that is parallel to the pivot axis of any one of the arms, the straight line intersects that arm.
