More specifically, it relates to a motorized joint secured by a brake activated by default spring effect, an actuator for disabling the brake and release the operation of the joint. The human body has a very large number of joints connecting bone or limbs. For example, there are about 40 joints in a lower human limb, from the hip to the ankle. These joints are movable by means of muscles, and have various forms to allow varied movements. Many attempts have been made in humanoid robots to reproduce the behavior and movements of the human being. Various types of joints are known which are capable of driving one member relative to another according to one or more degrees of freedom by means of an electric motor. A delicate situation is that of a power failure that can for example intervene following a faulty computer or a loss of battery charge. The drive by the electric motor is interrupted, the joint is free and the robot is likely to fall. This situation is all the more delicate as the robot is of large size and mass. In the perspective of widespread use and by any public, we seek to improve the safety of use of humanoid robots.

Advantageously, the hinge is configured so that: the bell is made of a metallic material and is substantially cylindrical in shape, the pad is made of an elastomer material and is configured to come into contact with the bell along a radial section of the bell.

FIGS. 1a and 1b show two examples of humanoid robots that can be equipped with a secure hinge according to the invention; FIGS. 2a and 2b represent, in a first perspective view, a first example of secure articulation, respectively in a 3a, 3b and 3c represent in a top view the example of secure articulation, respectively in the secured position, the operational position, and in the two superimposed positions, FIGS. 4a and 4b represent, in a second perspective view, the example of secure articulation, respectively in the operational position and the secure position, FIGS. 5a and 5b show, in a third perspective view, the example of secure articulation, respectively in the position in the operational position and the secure position, FIG. secure articulation. For the sake of clarity, the same elements will bear the same references in the different figures.
    [0007] Figures la and lb represent two examples of humanoid robots developed by ALDEBARAN ROBOTICSTM. The humanoid robot 10 shown in FIG. 1a comprises a head 1, a torso 2, two arms 3, two hands 4, two legs 5 and two feet 6. The humanoid robot 10 'represented in FIG. 1b comprises a head 1, a torso 2, two arms 3, two hands 4 and a skirt 7. These two robots comprise several articulations allowing the relative movement of the different members of the robot in order to reproduce the human morphology and its movements. The robots 10 and 10 'comprise, for example, a hinge 11 between the torso 2 and each of the arms 3. The hinge 11 is motorized about two axes of rotation to enable the arm 3 to be moved relative to the torso 2 in the manner of possible displacements by a shoulder of a human being. The humanoid robot 10 also includes a plurality of joints for moving the robot's legs and reproducing the movement of the walk, particularly hip-like joints between the torso and the thigh, at one knee, between the thigh and the leg. , and at an ankle between the leg and the foot. Several forms of motorized joints are implemented, causing one of the members to move around one or more degrees of freedom in rotation.
    [0008] The humanoid robot 10 'has a different architecture. To improve the stability and lower the center of gravity of the robot, the robot does not include a leg but a skirt 7 comprising at its base a tripod 14 capable of moving the robot. The skirt also comprises a first hinge 12 resembling a knee, between a leg 7a and a thigh 7b. A second articulation 13 resembling a hip is mounted between the torso 2 and the thigh 7b. These two joints 12 and 13 are motorized pivot links about an axis of rotation. The axis of rotation Xa of the hinge 12 and the axis of rotation Xb of the hinge 13 are substantially parallel to an axis connecting the two shoulders of the robot, for tilting the robot forward or towards the back.
    [0009] The humanoid robot 10 'standing up is about 1.1 to 1.2 meters for a total mass of about 25 to 30 kg. We try to ensure that the upper part of the robot can not rotate the joint under the effect of its own weight. The secure hinge according to the invention is intended to prevent the fall of the upper part of the robot, for example from the thigh to the head by rotation around the hinge 12, even in the event of a break. power supply of the joint. More precisely, the articulation according to the invention makes it possible to block the rotation of the articulations when the upper part of the robot is inside a cone with a vertical axis and an angle of the order of 10 degrees. The invention is described below for a motorized articulation with a degree of freedom of the pivot connection type, implemented in a large robot similar to the humanoid robot 10 ', and in particular for a knee-like or a knee-like joint. hip. It is understood that the invention is not limited to this particular application. More generally, the articulation according to the invention is intended to be mounted between a first and a second member of a robot, such as a humanoid robot, an animal robot or even an industrial robot. The first and second members are generally mechanical subassemblies that are intended to move relative to one another. By member, we mean in the following a mechanical subset of the robot such as a leg, thigh, torso, a head, an arm, a hand, or a combination thereof. Note also that if the following figures detail a particular example of a hinge-type articulation with a degree of freedom, it is understood that the invention applies in principle to any type of joint, for example a hinge to two degrees of freedom in rotation, or an articulation with one or more degrees of freedom in translation. In general, the invention relates to a hinge comprising a motor capable of moving a second member relative to a first member. Figures 2a and 2b show in a first perspective view an example of secure articulation, respectively in a secure position and an operational position. The hinge 20 is intended to be mounted between a first and a second member not shown in the figures. The hinge 20 comprises: a motor 21 capable of driving the second member in motion relative to the first member, the motor comprising a fixed part intended to be connected to the first member and a mobile part that can be moved in relation to the part fixed and intended to be connected to the second member, - a brake 22 capable of exerting a force on the movable part of the motor 21 by spring effect, to prevent the movement of the movable part relative to the fixed part, - an actuator 23 able to move the brake 22 by opposing the spring effect, so as to release the movable portion of the motor 21 of the brake force and allow the motor 21 to drive in motion the movable portion relative to the part fixed.
    [0010] The motor 21 is preferably an electric rotary motor, comprising a motor base 25 and a shaft drivable in rotation with respect to the base 25 about an axis X. The motor base 25 forms the fixed part of the motor and comprises a base in the form of disc to be fixed to the first robot member by means of six brackets 25a angularly distributed around the base of the base. The shaft (not visible in the figures) forms the movable part of the motor and is integral with a motor bell 26 of substantially cylindrical shape. The shaft passes through the motor base and is intended to be connected to the second member preferably via a gear device (not shown). Thus configured, the electric motor 21 drives the shaft in rotation with respect to the base, causing the second member to rotate relative to the first member. The hinge 20 also includes the brake 22. In FIG. 2a, the hinge is shown in a secured position, in which the brake exerts a force on the moving part of the motor to prevent the rotation of the shaft. In FIG. 2b, the articulation is represented in an operational position, in which the brake is displaced so as to release the motor from the braking force and allow the shaft to be rotated. In the secure position, the brake 22 exerts a force on the motor bell 21 preferably consisting of a metallic material, by means of a pad preferably consisting of an elastomeric material, coming into contact with the cylindrical bell along a radial section of it. The pad exerts a force on the motor bell so as to prevent by friction the rotation of the shaft relative to the base. In the example shown, the brake 22 comprises a fixed arm 27 secured to the motor base 25 and a movable arm 28. The movable arm 28 has a half-moon shape between a first end 50a and a second end 50b, forming a half -cover partly covering the motor bell. The movable arm 28 is connected by the first end 50a to the fixed arm 27 by means of a pivot connection 29 of axis X 'substantially parallel to the axis X of rotation of the shaft. In this first example of articulation, the pad is fixed on an inner surface of the movable arm, so as to come into contact with the radial surface of the bell 26, during a rotation of the movable arm about its axis X '. The pad is fixed substantially equidistant from the first and second ends 50a and 50b of the movable arm 28. The brake 22 also comprises a spring mechanism, preferably a helical spring 45 wound around the axis X 'and taking support on the fixed arm 27 and the movable arm 28 so as to exert a force tending to move the movable arm and the fixed arm. The force exerted by the spring between the movable arm and the fixed arm, is transmitted to the pad in contact with the bell, to lock the shaft in rotation. By default, the joint is locked in rotation. The joint also comprises an actuator 23 capable of moving the brake by opposing the spring effect, so as to release the motor from the brake force and allow the motor to drive the shaft in rotation. In the example shown, a linear actuator (not shown) is mounted between the fixed arm 27 and the second end 50b of the movable arm 28. The linear actuator comprises a rod movable in translation between two positions along an axis Y inside a sheath. The sleeve is fixed on a support 31 secured to the fixed arm 27. The rod has at its end a spherical shape cooperating with a spherical imprint 32 arranged in the movable arm 28. The stroke of the rod between its two positions defines the movement of the arm mobile between the secure position and the operational position. By default, for example when the joint is not electrically powered, the rod is held by the effect of the spring in its most extended position. Conversely, when the joint is energized, the actuator can be controlled to retract the rod into the sleeve exerting a force counteracting the spring effect. Various embodiments of the linear actuator are possible, in particular a linear actuator controllable by electromagnet.
    [0011] The hinge also includes means for manually moving the brake to release the rotational movement of the two members. In particular, an inclined plane 40 is arranged on the movable arm, near its second end, so that a tool moved parallel to the axis X of rotation of the shaft, and against this inclined plane 40, can move the movable arm from the secure position to the operative position, counteracting the spring effect. A second inclined plane 41, visible in Figures 4a and 4b, is also arranged near the center half-moon shape of the movable arm. In practice, the motorized articulation shown in the figures is integrated on the robot, inside an outer casing shown in Figures 1a and 1b conferring the external appearance of the robot. Advantageously, the outer casing comprises an orifice arranged facing the inclined plane of the articulation, allowing the insertion of a suitable key to release the brake and allow manual folding or unfolding articulated members.
    [0012] According to one aspect of the invention, securing the joint therefore consists in providing the drive motor with a brake mechanism activated by default by means of a spring mechanism, and means for disabling the brake mechanism. countering the spring mechanism. Thus, the joint is blocked in case of power failure of the joint, related to a loss of battery charge, a computer crash, or a voluntary emergency stop. The means for deactivating the brake mechanism comprise electronically controllable means, it is the role of the actuator, and manual means is the role of inclined planes.
    [0013] Figures 3a, 3b and 3c show a top view of the example of secure articulation, respectively in the secure position, the operative position, and in the two superposed positions. In the example shown, the diameter of the motor base is about 90 mm, the height of the joint is about 40 mm. In the secure position, the movable arm 28 comes to press the elastomer pad against the motor bell 26. The half-moon shape of the movable arm is advantageous. It allows to fit the shape of the movable bell so that the elastomeric pad can be brought into contact with the bell along a radial section of the shaft. The pad is not visible in the figures, its location is represented by means of the mark 43. Typically, a substantially rectangular pad approximately 15 mm in height and width is retained. The half-moon shape also makes it possible to secure the joint in a small space. Typically, a 2.5 mm stroke of the linear actuator, corresponding to an angle α of about 4 degrees, separates the secure position from the operative position. Note also that the joint is advantageously intended to be connected to the two members of the robot so that the mobile arm in the form of a half-moon is positioned in the upper part of the motor bell. Thus configured, the movable part of the brake comes to press the shoe, not only by spring effect but also in a natural way by the effect of gravity. In the absence of energy and in the case of a weakening of the power of the return springs, the articulation naturally remains braked by the pad. The joint remains locked as an external force exerted between the movable part and the fixed part of the engine, remains lower than the force exerted on the engine by the brake. When the force applied between the movable part and the fixed part of the motor is greater than the force exerted by the brake, the moving part is driven in motion. The friction force being insufficient to immobilize the bell against the pad, the shaft slides in rotation despite the braking exerted by the pad. The moving part is braked but not immobilized. It is possible by a suitable dimensioning of the spring and the shoe to define the force exerted on the motor by spring effect. In other words, the brake may be configured to prevent movement of the movable portion relative to the fixed portion to a predetermined threshold force; a force greater than this threshold force, exerted between the movable part and the fixed part generating a movement of the movable part relative to the fixed part. The ability to adjust the value of this threshold force is a particularly advantageous feature of the invention. It becomes possible to adapt the behavior of the joint according to the 35 situations encountered. In the case of the humanoid robot 10 ', the threshold force is determined in such a way that the articulation remains locked in rotation as long as the upper part of the robot (here including the thigh 7b, the torso 2, the arms 3 and the head 1) is inside a cone of vertical axis and angle of the order of 10 degrees. Outside this cone, the force exerted on the articulation by effect of the gravity of the upper part of the robot is greater than the threshold force and the members are rotated; the joint being simply braked. The speed of the braked rotation is advantageously configurable by the dimensioning of the pad and the spring. The braked rotation movement is also advantageous to secure the joint, avoiding the rupture of components exposed to significant effort. In other words, it preserves the mobility of the parts involved in the gear chain following the engine. This mobility makes it possible, for example, to withstand a violent impact on a joint implementing the braking system in its frictional position, since the gears can rotate, even slowly, in order to dissipate the energy of the impact. In the opposite hypothesis of a blockage of the joint by mechanical means independent of the force exerted, the impact force in the event of a fall or violent impact would be reflected on the entire chain of articulation training. , ultimately causing the breaking of the most fragile components, for example the motor or the gear device. This implementation of a brake acting by friction is advantageous because it defines two ranges of use, a first range in which the joint is blocked, any force exerted between the members not causing movement of the joint; and a second range in which a force exerted between the limbs causes movement of the limbs; the articulation being braked. Figures 4a and 4b show in a second perspective view the example of secure articulation, respectively in the secure position and the operational position. This second view illustrates the implantation of the linear actuator on the motor base 25, near the second end 50b of the movable arm 28. The linear actuator comprises a sleeve, fixed on the support 31 arranged in the fixed arm 27, and a rod whose spherical end cooperates with the spherical imprint 32 arranged in the movable arm to form a ball joint. In the absence of power supply or control of the actuator, the rod is held in the retracted position by the effect of the spring. The displacement of the rod in translation along the Y axis, controlled by the linear actuator, makes it possible to counter the spring effect and to release the shaft from the grip of the brake.
    [0014] Advantageously, the fixed arm 27 and the movable arm 28 are made of a thermoplastic material filled with glass fiber, preferably of PA66-GF35 type. Various components, such as the support 31, can be reported on the movable arm by an overmolding type process. The pad may be made of an elastomeric material based on polyurethane. The pad is preferably attached to the movable arm by a bi-injection type process, allowing molecular cohesion adapted to the forces that can be exerted on the pad. Advantageously, the assembly comprising the fixed arm, the movable arm, the shoe, the coil spring and the actuator is assembled in a first step. The pre-assembled assembly is then mounted on the engine base 25. For this purpose, the engine base and the fixed arm comprise means making it possible to preposition the assembly relative to the engine, before fixing by means of the three fastening tracks. arranged in the fixed arm and the motor base.
    [0015] Figures 5a and 5b show in a third perspective view the example of secure articulation, respectively in the secure position and the operational position. This last perspective view shows the detail of the pivot connection 29 between the fixed arm 27 and the movable arm 28. The spring 45 is wound around the axis X 'and bears against a surface of the movable arm and a surface of the arm fixed, so as to exert a force tending to spread the fixed arm and the movable arm. Advantageously, the fixed arm also comprises means 47 of force recovery, between the motor base and the fixed arm, to reflect the force exerted by the spring on the fixed arm to the motor base. It is also envisaged to fix means for measuring the position of the movable arm, the measured position information being transmitted to an electronic control unit for controlling the motorized articulation. In particular, it is envisaged optical measurement means. For this, the movable arm comprises an end 48, visible in Figure 2b, configured to intercept - in the secure position only - an optical beam axis parallel to the X axis. Figure 6 represents a view from below a second example of secure articulation. This second example of articulation has many similarities with the first example already described. Like before. the brake comprises a fixed arm secured to the base and a movable arm 28 connected to the fixed arm by a pivot connection 29. In Figure 6, only the movable arm 28 of the brake is shown. The definition and principle of operation of the other components, such as the motor, the actuator or the fixed arm of the brake, are not systematically repeated in detail. This second example of articulation is distinguished from the first example by the definition of the pad coming into contact with the motor bell. In this second example, a shoe 50 intended to come into contact with the motor bell 15 to brake the latter, is mounted on a plate 51 mounted on a swivel on the movable arm 28. The wafer 51 has a specific shape configured to flow under the the combined action of static and dynamic tangential friction forces and pressure. This deformation being possible symmetrically, whatever the direction of rotation of the motor bell.
