Definitions
- the present invention is in the field of industrial robotics.
- the invention more particularly relates to a nacelle for a parallel robot intended to act on an object, the nacelle comprising:
- each armature comprising at least two pairs of ball joints
- each of the armatures respectively by four hinges oriented along four axes of hinge substantially parallel to an axial direction, the four hinge axes defining a parallelogram in a plane perpendicular to the axial direction, the parallelogram being movable between a plurality of configurations in which the two sides corresponding to the two armatures are substantially parallel to an orientation direction (D1) substantially perpendicular to the axial direction, and
- a base mounted on the nacelle and intended to be connected to an effector own to act on the object.
- the invention also relates to a parallel robot intended to act on a parallel object intended to act on an object, characterized in that it comprises:
- each of the articulated arms being mounted respectively on one of the pairs of ball joints of the nacelle, and
- the invention finally relates to a method implementing such a robot.
- the axial direction is generally substantially vertical.
- Such robots are intended to perform object manipulations (so-called pick-and-place
- the robot known as "Quattro” includes an articulated pod and four actuating arms. This robot has four degrees of freedom: three translations in space, and a rotation around the vertical to change the orientation of the manipulated object.
- the nacelle has the shape of a deformable parallelogram in a substantially horizontal plane. The rotation of the object is controlled by the deformation of the nacelle.
- a first solution consists, through the control of the four articulated arms, to impose a given orientation to the base and thus the effector and the object.
- the accelerations printed on the object result in a torque exerted on the base around the axial direction.
- Such a torque is transmitted to the actuators of the robot, which reduces all the possibilities of printing efforts in translation, and thus to achieve high dynamic performance.
- a nacelle rigid that is to say, not deformable in its plan.
- a rigid nacelle provides the three degrees of freedom in translation and constrain the rotational movement of the effector, but has the disadvantage of over-compressing the four actuators. Indeed, since three actuators are sufficient to produce the three translational movements, the fourth actuator must be perfectly synchronized with the other actuators, under penalty of deformation, or even dislocation of the robot. Such a perfect synchronization is difficult to achieve because it requires control of the actuating forces and thus significant computing power to control the robot.
- An object of the invention is therefore to provide a nacelle adapted to a parallel robot with four articulated arms and to constrain the rotation of the object around the axial direction, while achieving high dynamic performance, and does not require too much computing power.
- the invention relates to a nacelle of the type described above, wherein the base is connected to each bridge respectively by at least one hinge oriented along a connecting axis substantially parallel to the axial direction, both axes connecting the base defining in said plane a segment parallel to the direction of orientation in all configurations of the parallelogram.
- the nacelle comprises one or more of the following characteristics, taken separately or in any technically possible combination:
- the connecting axes of the base are respectively located substantially in the middle of the sides of the parallelogram corresponding to the bridges;
- each segment of the parallelogram corresponding to one of the armatures has a length L1 and each segment of the parallelogram corresponding to one of the bridges has a length L2, the ratio L1 / L2 being greater than or equal to 2.0;
- the frames and bridges of the nacelle came from material, the hinges of the nacelle being made by local thinning of the nacelle.
- the invention also relates to a parallel robot intended to act on an object, the robot comprising:
- each of the articulated arms being mounted respectively on one of the pairs of ball joints of the nacelle, and
- the robot comprises one or more of the following characteristics, taken separately or in any technically possible combination:
- the articulated arms are adapted to print a translation movement to the nacelle with respect to the support, and to deform the parallelogram between the configurations of said plurality, the direction of orientation remaining fixed relative to the support during the translational movement and in all configurations of said plurality;
- the axial direction is substantially vertical
- Each articulated arm comprises a proximal portion rotatably mounted on the support, and a distal portion connected to the proximal portion by two ball joints, and connected to the nacelle by one of the ball joint pairs.
- the invention finally relates to a method implementing a robot as defined above, comprising the step of acting on the object using the effector.
- the method comprises the following steps: - To translate a translation movement to the nacelle relative to the support by means of the articulated arms, the orientation direction remaining fixed relative to the support, and

- the effector 60 is fixed on the base 88 so as to be integral in rotation with the base 88 around the central axis M.
- the segment EF defines the orientation of the entire base 88.
- the nacelle 55 is movable between the configuration shown in Figure 2 and a plurality of configurations, two of which are shown in Figures 3 and 4.
- the configuration of the nacelle 55 shown in FIG. 3 is such that the parallelogram ABCD is no longer a rectangle.
- the angle ABC is then an obtuse angle.
- Such a configuration results from the configuration shown in FIG. 2 by translating the armatures 80, 82 relative to one another in the direction of orientation D1.
- the nacelle 55 is in a configuration in which the parallelogram ABCD is such that the angle ABC is acute.
- Such a configuration is obtained from the configuration shown in Figure 2 by translating the armatures 80, 82 relative to each other in the direction of direction Dl, in a direction opposite to that which gives the configuration represented in FIG.
- the configurations of the parallelogram ABCD are for example defined by an angle ⁇ formed by the segment AB with the transverse direction T.
- the angle is substantially zero. In the configuration of Figure 3, the angle is for example +5 degrees.
- the angle is for example -5 degrees.
- the angle a is for example in a range of -5 degrees to +5 degrees.
- the actuators 15, 20, 25, 30 respectively make it possible to rotate the proximal portions 68 of the articulated arms 35, 40, 45, 50 respectively about the axes D1, D2, D3, D4 relative to the support 10. This has the effect of moving the spheres 72, 74 along circular paths in planes substantially parallel to the axial direction V.
- the uprights 76, 78 of each distal portion 70 of each articulated arm 35, 40, 45, 50 remain parallel to each other.
- the nacelle 55 maintains its orientation in space with respect to the support 10. In the example shown, the nacelle 55 remains substantially parallel to the plane P and does not rotate relative to the support 10 around the axial direction V.
- the four articulated arms 35, 40, 45, 50 constitute four kinematic chains to which correspond three degrees of freedom in translation of the nacelle 55, and an additional degree of freedom corresponding to the deformations of the parallelogram ABCD defined by the nacelle 55.
- to the four angular positions of the proximal portions 68 of the articulated arms 35, 40, 45, 50 corresponds to a single position of the nacelle 55 in space relative to the support 10, and a configuration of the parallelogram ABCD formed by the nacelle, that is, ie a value of the angle a.
- the articulated arms 35, 40, 45, 50 deform the nacelle 55 so that the segments BC and AD remain substantially parallel to the direction of orientation D1.
- the segment EF is itself parallel to the segments AD and BC.
- the orientation of the base 88 around the axial direction V does not change, whatever the configuration of the parallelogram ABCD, because the orientation of the base is determined by the orientation of the segment EF.
- the force torques possibly acting on the effector 60 around the axial direction V do not transmit to the articulated arms 35, 40, 45, 50, and therefore are not transmitted to the actuators 15, 20, 25, 30.
- the robot 1 is adapted to constrain the rotation of the object 5 around the axial direction V without this soliciting the actuators and without this requires too much computing power.
- This achieves high dynamic performance and also increases the life of robot 1.
- the pod 55 makes it possible to use a standard control with independent axes typical of robots with four articulated arms. This makes it possible to increase the gains of the servo loops, and thus to improve the performance of the robot 1.
- the fourth kinematic chain represented by the fourth articulated arm makes it possible to homogenize the performance of the robot 1, that is to say that they do not degrade so quickly at the edge of the workspace of robot 1.
- the use of the degree of internal mobility of the nacelle 55 constituted by the plurality of configurations of the parallelogram ABCD in the plane P does not affect the transmission of the mechanical forces of the actuators 15, 20, 25, 30 towards the effector 60.
- This degree of internal mobility of the nacelle 55 allows movements, advantageously infinitesimal, to compensate for the possible errors of the command control models and the engine beats of the actuators 15, 20, 25, 30. This internal mobility also releases the internal stresses. Actuation of the robot 1.
- the lifetime of the robot 1 is increased, particularly that of expensive elements of the actuators 15, 20, 25, 30 such as motors, reducers and power amplifiers.
- the robot 1 has more homogeneous performances than those of a robot with three articulated arms for the same work space, that is to say say the zone of displacement of the object 5.
- the hinges of the nacelle 55 55 are preferably mechanically stressed.
- a pair of external forces possibly acting on the effector 60 around the axial direction V does not solicit the motors of the articulated arms 35, 40, 45, 50 contrary to what occurs in a robot with four conventional articulated arms.
- the four articulated arms 35, 40, 45, 50 are controlled independently and slaved in position.
- the robot 1 has a kinematic redundancy, instead of an actuation redundancy. It is thus possible to use a conventional industrial control system, whose minimum sampling period is only 1200 ms.
- the robot 1 is also more efficient than a rigid nacelle robot type "Delta” in terms of its acceleration capacity and its resistance to external forces.
- the robot 1 is hyper static of degree 1, which is an advantage in terms of rigidity, thanks to a better distribution of forces in the uprights 76, 78 of the articulated arms 35, 40, 45, 50.
- the hinges 1 16, 1 18, 120, 122, 124, 126 are made by thinning material.
- the nacelle 25 is achievable by molding. It is of course possible to use more conventional joints between the different elements of the nacelle 55.
- the orientation of the effector 60 around the axial direction V does not change either during translational movements of the nacelle 55 caused by the articulated arms 35, 40, 45, 50"
- the orientation of the effector is not affected by the displacements in translation of the nacelle made by the articulated arms, nor by the more or less crushed shape that the parallelogram ABCD is made to take during these displacements in translation.
- the orientation of the effector 60 around the axial direction V is the same as that of the base 88 and is given for example by the segment EF.
- the effector 60 comprises for example a portion 61 fixed on the base 88 of the nacelle 55, and a portion 62 of the gripping of the object 5 ( Figure 1).
- the portion 61 is fixed in orientation around the axial direction V relative to the base 88 during the movements of the nacelle 55 and / or during the deformations of the parallelogram ABCD.
- the gripping portion 62 is for example a simple gripper. In a variant (not shown), the gripping portion 62 is a more complex tool, known in itself to those skilled in the art.
- the portion 62 is for example rotatable about the axial direction V relative to the portion 61, and is advantageously actuated by a motor (not shown), as already mentioned above.
- the axial rotation of the portion 62 relative to the portion 61 is in no way the result of a deformation of the parallelogram ABCD.
- the nacelle 55 is shaped so that it is not a deformation of the parallelogram ABCD which causes axial rotation of the portion 62.
- the axial rotation of the portion 62 relative to the portion 61 is the result of a specific actuation and is not related to the shape of the parallelogram ABCD.
