<p>Articulated device with three degrees of freedom in translational movement having an active end (6) intended to interact with an external environment, a first pantograph (100) and a second pantograph (200) which are combined in series, the first pantograph (100) being acted upon directly at one of its ends (A1, B1) by a linear actuator (110), the second pantograph being acted upon at two of its ends (A2, B2, M2) by two actuators, the first (110), second (210) and third actuators each having a direction of travel (Y, X, Z) that is orthogonal to the other two directions of travel, the active end being supported by one end (M1) of the first pantograph in such a way that the relationship connecting the movement of the active end in each of the directions of the actuators and the movement of each of the actuators is invariable.</p> |
