Abstract: The articulated multiple-axis robot structure has a frame, an arm and a forearm, a shaft for attaching a tool, an actuator commanding the pivoting of a slide-socket, an actuator commanding the pivoting, a rotatable nut-socket, and a coupling device for securing the sockets in rotation. The coupling device having a coupling washer between the sockets and connected in rotation with one of the slide-socket and the nut-socket. The coupling washer is movable between a coupling configuration, in which the translation of the shaft relative to the forearm is locked, and an operating configuration, in which the translation and rotation of the shaft relative to the forearm are freed by a first electromagnet.

Abstract: The articulated multiple-axis robot structure according to the invention has a frame, an arm and a forearm, a shaft (15) for attaching a tool, an actuator commanding the pivoting of a slide-socket (14A), which is rotatable relative to the forearm and translatably connected to the forearm, an actuator commanding the pivoting a nut-socket (14B) that is rotatable relative to the forearm and connected in translation to the forearm and a coupling device capable of securing the sockets (14A, 14B) in rotation. This device comprises a coupling washer (18), arranged between the sockets (14A, 14B) and connected in rotation with a first socket from among the slide-socket (14A) and the nut-socket (14B).

Abstract: An articulated structure for a multi-axis robot includes a base having an arm hinged to the base about a first axis and a forearm hinged to the arm about a second axis parallel to the first axis, and wherein the forearm forms a deformable parallelogram structure which includes two connecting rods that are hinged to two plates about respective axes that are perpendicular to the first and second axes. The structure also includes a first electric actuator controlling pivoting of the arm about the first axis, a second electric actuator controlling pivoting of the forearm about the second axis, and a third electric actuator mounted directly on one of the base and the arm for controlling pivoting of one of the connecting rods relative to the plates about the axes that are perpendicular to the first and second axes.

Abstract: A robot structure that has a base, at least a first arm that moves with respect to the base both in translation and in rotation, a movement mechanism for moving the first arm with respect to the base, a member for accepting a tool, and a power supply assembly. The movement mechanism includes a hollow member which moves in translation with respect to one of either the base or the first arm, while being incapable of translational movement independently of the other of the base or the first arm, and the hollow member being movable in rotation with respect to one of either the base or the first arm, while at the same time being incapable of rotational movement independently of the other of the base or the first arm.

Abstract: The articulated structure for a multi-axis robot comprises a stationary base; an arm hinged to the base about a first axis; a forearm hinged to the arm about a second axis parallel to the first axis, the forearm forming a deformable parallelogram structure and comprising two connecting rods that are hinged to two plates about respective axes that are perpendicular to the first and second axes. This structure also comprises a first electric actuator controlling pivoting of the arm about the first axis; a second electric actuator controlling pivoting of the forearm about the second axis; and a third electric actuator controlling pivoting of one of the connecting rods relative to the plates about the axes that are perpendicular to the first and second axes. The third actuator is mounted on the base or on the arm.

Abstract: This robot structure comprises a base structure (2), at least a first arm (40) that can move with respect to this base structure, both in terms of translation and in terms of rotation, movement means (12, 22, 32) for moving this first arm with respect to the base structure, an accepting member (70) for accepting a tool (72), and a power supply assembly (80).

Abstract: A mechanism for manoeuvring a door more particularly designed to be associated with a bar for avoiding panic. The mechanism comprises a pivoting bolt (26) provided with a slot wherewith it can co-operate with a lock-bolt keeper, a pivoting cam (35) for preventing the bolt from rotating towards a so-called loose escaping position and a member actuating (45) the cam to release the bolt.
