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.

Articulated structure of a multiple-axis robot and robot comprising such a structure

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.

Articulated structure for a multi-axis robot, and a robot including such a structure

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.

SCARA-type robot structure and corresponding robot

The robot comprises: &#x2014;a controller (C), including power modules () for supplying the motors () of the arm (A) of the robot (R), a CPU unit (), for calculation and processing and connection means (, B), between the arm (A), the power modules () and the CPU unit (). The connection means (, B) comprise a single functional bus (B) which connects a control unit (), associated with the CPU unit (), firstly to the power modules () and, also, to the digital interfaces () with the sensors () of the arms (A). Said interfaces () are either integrated with the arm (A) or located in the immediate vicinity thereof.

Multi-axis robot provided with a control system

In order to fabricate an epicycloidal reducer including at least one circular cam () whose outer peripheral edge () is provided with a first set of teeth () suitable for co-operating with a stationary second set of teeth, said cam being pierced by at least a first bore () for receiving a drive finger held stationary in a second bore () formed in a support () secured to an outlet shaft of the reducer, the first bore () in the or each cam () and the second bore () in the support () are machined at least in part in a single operation while in alignment (X) one with the other.

Method of fabricating a reducer, and a robot incorporating such a reducer

A process for assembling and an epicyclic reduction gear comprising a plurality of planets provided with outer toothings moveable rotatable about a shaft which are engaged with the toothings of, at least one adjacent gear ring. The shaft of the planets is mounted on a planet-holder so that it is adapted to move with respect to said planet-holder both radially and angularly in a plane perpendicular to the principal shaft of the reduction gear. The rotation shaft of each planet may be radially and angularly adjusted to a position where its outer toothing meshes with the toothing of the adjacent gear ring and may thereafter be secured in position.
