- the present invention relates to the technical field of performing all operations, for example cutting, welding, marking, stripping, painting, surfacing, positioning a sensor or any type of tool. analysis, etc., on an object present in a working environment, the positions and geometries of the object and of the working environment possibly being scalable and / or insufficiently defined to be able to carry out said operations.
- the invention applies to the technical dismantling sector, in which measuring, cutting and gripping operations are carried out on objects possibly presenting risks associated with radioactivity, without this being limiting.
- the invention relates more precisely to a method and an installation for automatically performing an operation on an object with a tool carried by a polyarticulated system and movable in a working environment, the positions and geometries of the object and of the working environment being scalable and / or insufficiently defined to be able to perform said operation in automatic mode.
- the operation can be of any nature whatsoever in any type of environment, with any type of tool and carried out especially type of object.
- the present invention for example finds an advantageous application for performing an operation on an object in a risky and confined environment, inaccessible to an operator or in which an operator operates with difficulty.
- dismantling operations can be carried out manually by an operator in a confined environment.
- Dismantling operations include operations of measuring, cutting and gripping the object.
- the purpose of the cutting operation is to generate elements of smaller dimensions with the aim of optimizing the filling of the waste containers into which they are introduced, for example.
- the operations cannot be carried out on contact by an operator, the tool (measuring, cutting, gripping) must then be carried by a polyarticulated system to carry out this operation.
- the operator controls the system remotely using a control reference, in indirect vision using cameras and screens.
- the drawbacks of such a system are on the one hand its high cost, on the other hand the imprecision of its control in terms of speed, effort and positioning, leading to a long implementation time and premature wear of the consumables of the tools ( blades, discs).
- the invention aims to remedy the drawbacks of the prior art by providing a method and an installation for performing an operation on an object in a working environment, making it possible to ensure optimum conditions of safety, precision and speed. .
- the method comprises at least:
- step A consisting of: o capturing an image of the object and all or part of the working environment, with at least one 3D sensor, in the form of an overall point cloud, o in merging this image with a pre-existing CAD model of the polyarticulated system and a possible pre-existing CAD model of all or part of the environment as built, resulting in a working image and o defining anti-collision parameters;
- step B consisting in defining, preferably by the operator, a trajectory of the tool on the part of the working image representing the object, and in carrying out a simulation of the corresponding displacement of the polyarticulated system and of the tool in the working picture to ensure that the operation is feasible;
- step C consisting, if the operation can be carried out according to step B, in performing the actual movement of the polyarticulated system carrying the tool along the path defined in order to perform the operation on the object.
- 3D sensor is understood to mean any means for digitizing an object or part of an object in the form of a three-dimensional image, and includes in particular 3D cameras, laser scanners, video means, webcams. ..
- the anti-collision parameters are for example threshold distances from which safety actions are carried out automatically such as the total stopping of any movement or the reduction in the speed of movement of the polyarticulated system and of the tool. , for example up to a threshold speed which then constitutes an anticollision parameter.
- the invention makes it possible to carry out operations in automatic and remote mode in an environment that is initially uncertain or unknown or inaccessible while guaranteeing their correct execution.
- the invention is advantageous in that, before any movement of the polyarticulated system, the working environment is digitized in the form of an overall point cloud. In this way, the position of the various obstacles vis-à-vis the movement of the polyarticulated system, namely the elements present in the working environment and the object on which the operations must be carried out, is known. Thus, any collision between the polyarticulated system or its tool and the elements of the environment can be avoided, thanks to the anti-collision parameters.
- the operator views the working environment and the object in a cloud of points on the display, and defines a tool movement path to perform the desired operation, for example a cutting operation.
- the invention is also advantageous in that the method makes it possible to carry out a simulation, in particular in CAD, of the corresponding displacement of the polyarticulated system and of its tool in order to ensure that the displacement is achievable without collision.
- the simulation of the displacement confirms its feasibility
- the actual displacement of the polyarticulated system carrying the tool can be executed to perform the operation as such on the object.
- the method is thus carried out in at least three steps, namely: a step A of securing the environment and the object by digitization in the form of an overall point cloud, a step B of definition and simulation trajectories, and an execution step C.
- the method also comprises a step A ', between step A and step B, consisting in controlling the movement of the polyarticulated system to capture detailed images of areas of the object with a 3D sensor carried by the polyarticulated system, in the form of a point cloud denser and more precise than the overall point cloud and to integrate into the working image the captured images of the corresponding area of the object, replacing the part corresponding value from the aggregate point cloud.
- a step A ' between step A and step B, consisting in controlling the movement of the polyarticulated system to capture detailed images of areas of the object with a 3D sensor carried by the polyarticulated system, in the form of a point cloud denser and more precise than the overall point cloud and to integrate into the working image the captured images of the corresponding area of the object, replacing the part corresponding value from the aggregate point cloud.
- This additional step makes it possible to provide an improved working image, with increased precision in order to define the different trajectories of the operation to be carried out. Moreover, this additional step also makes it possible to capture images of the areas not visible by the sensor used for step A, thanks to the displacement of the polyarticulated system, and thus to complete the working image.
- the 3D sensor carried by the polyarticulated system can be permanently attached to it, or else be stored nearby.
- the method comprises a step A ", between step A is step A ', consisting in automatically moving the polyarticulated system to grip and connect to the 3D sensor stored nearby.
- the method comprises a step C ', between step B and step C, consisting in automatically moving the polyarticulated system in order, optionally to disconnect and remove a 3D sensor, and to connect to the tool. stored nearby.
- This characteristic makes it possible to have a plurality of tools available stored nearby, intended to be connected to the polyarticulated system.
- the method also comprises, prior to step B, a step B ′ consisting in selecting, in and for the simulation of step B, in a database of tools , the tool to perform the operation.
- the method is also remarkable in that, during step C, the speed of movement of the polyarticulated system carrying the tool in direct contact with the object perhaps, according to need, regulated in real time according to a direct or indirect measurement of the force undergone by the tool.
- the displacement speed of the polyarticulated system is automatically reduced when the 3D sensor or a part of the polyarticulated system approaches the object or a part of the working environment, and movement is automatically stopped when the 3D sensor or part of the polyarticulate system is at a safe distance from the object or part of the working environment, depending on the parameters collision avoidance defined in step A.
- the definition of the tool path on the part of the working image representing the object according to step B consists of positioning on the working image either at least one starting point - end point pair, or at least one predefined geometric figure chosen from a library composed for example of at least one line, planes, masks, etc.
- the invention also relates to an installation for implementing the method described above, characterized in that it comprises a polyarticulated system and at least one 3D sensor, connected to a computer processing system and to a display, designed for : represent on the display an overall point cloud of the object and all or part of the working environment from images captured by at least one 3D sensor; represent a working image resulting from the fusion of the overall point cloud, a pre-existing CAD model of the polyarticulated system and a possible pre-existing CAD model of all or part of the environment as built, the processing system computer system being also designed to make it possible to define a trajectory of the tool on the part of the working image representing the object, and to perform a simulation of the corresponding displacement of the polyarticulated system and of the tool in the working image to ensure that the operation is feasible, and if the operation is feasible, to perform the actual displacement of the polyarticulated system carrying the tool along the path defined to perform the operation as such on the object.
