    Background of the invention
    The present invention relates to a method of treating a surface, and a corresponding automaton. More particularly, the present invention relates to a method of painting a surface by a robot assistant.
    There are already robots for treating a surface, for example to paint or sand. Such robots are used in the automotive field, for painting the bodies of vehicles. These robots are autonomous and are programmed to perform a series of operations without the control of an operator: they then replace one or more people by performing the tasks previously programmed in the robot control computer.
    However, these robots-painters, like other robots used on assembly lines, are motionless on the ground, and only the arm holding the tool, is mobile: their field of action is geographically limited. Moreover, and in order to avoid accidents with possible people who may be near the robots, they are generally surrounded by a safety zone in which the robot is brought to work and in which the individuals must not enter.
    There are also robots in the building. Such robots are used in particular to work in places that are difficult to access by individuals, or even banned. This is the case for example when the surface to be treated comprises high ceilings, or is located in an area with radiation risks. An example of a robot that can intervene under such conditions is described in particular in application FR 2 902 038.
    It can be seen that the robot is directly controlled by an operator, to treat the surface in its place and under its control. Thus, such robots are not autonomous, and need to be controlled continuously by an operator: the use of such a robot then makes it easier for the operator to work, but always requires his presence, whether next to or remote from the robot. The robot then does not replace the operator to perform the operation, but rather acts as a tool that remains under the control of the operator and does not act alone.
    Thus, the robot does not allow to perform work in place of an individual, but still requires supervision. In particular, the robot can treat a given surface only with the instructions given by the operator during the processing of said surface, in order to adapt the actions performed by the robot in real time.
    Object and summary of the invention
    The present invention aims to solve the various technical problems mentioned above. In particular, the present invention aims at providing a method for treating a surface by a PLC, and the corresponding PLC, enabling said PLC to autonomously and efficiently process said surface. Furthermore, the present invention also aims at providing a method of treating a surface allowing an automaton to operate alone, and in the presence of people around him.
    Thus, according to one aspect, there is provided a method of treating a surface to be treated, by means of an automaton comprising: a base configured to move on a floor, a platform mounted on the base and configured to moving, at least in part, perpendicularly to the base, for example vertically, and - a processing means, for example an arm, mounted on the platform and having a movable end configured to treat a given area, in which process: a) dividing the surface to be treated into subdivisions of area less than or equal to the given area, b) treating the surface of each subdivision by displacement of the processing means, and c) changing subdivision by displacement, for example vertical translation. , the platform and / or by moving the base on the ground.
    The method makes it possible to plan the treatment of the surface to be treated. More particularly, the method takes into account the structure of the automaton carrying out the surface treatment, to subdivide the surface to be treated. Thus, the automaton comprising a base moving on the ground, that is to say substantially horizontally, and a platform moving perpendicularly to the base, is substantially vertically, the method provides a cutting of the surface to be treated in contiguous subdivisions. The junctions between neighboring subdivisions may in particular be vertical or horizontal, so that the passage from one subdivision to another can be done, respectively, by horizontal displacement of the base or by vertical displacement of the platform. Each subdivision corresponds to the area that can be processed by the displacement of only the processing means on the platform. The method is therefore chosen so as to optimize the movements of the automaton during the treatment of the surface. Furthermore, the method allows the machine to move on the ground, to allow it to operate in any place, without having a limited action area, and while remaining predictable for people nearby by a sequenced work in subdivisions.
    More particularly, the automaton treats the surface to be treated in portions, and moves from subdivision to subdivision: it is thus easy, especially for people working near the automaton, to anticipate the movements thereof, and therefore to act accordingly: for example by avoiding to treat a surface close to the subdivision which will be treated by the automaton for example. The automaton can then work in collaboration with the people working around him: the automaton carrying out the repetitive and not technical tasks, while the professionals carry out the more specific works. Work scheduling by the PLC facilitates the simultaneous work of people nearby.
    We thus obtain a PLC that can work autonomously, without requiring the continuous supervision of a person. The operator intervention time on the PLC is therefore reduced, the operator can in turn perform a treatment of the surface at the same time as the automaton, for example by carrying out the work requiring a technicality or knowledge. -make special such as the treatment of specific surfaces such as the outline of wall outlets, the back of pipes, stairs, ...
    Preferably, the moving end of the processing means is configured to treat the surface of each subdivision by displacement parallel to the surface of the subdivision to be treated, for example in a vertical plane. The moving end of the processing means fulfills the role of the hand of a person performing the surface treatment. In the case of a spray treatment (paint or coating), this end is configured to remain substantially always at the same distance from the surface to be treated, so that the treatment performed by the moving end is uniform on the entire surface of the subdivision, or to change the distance separating it from the surface to be treated, in order to adapt the treatment to varying conditions. In the case of a contact treatment, for example sanding or painting with a brush or a buffer, this end is configured to substantially always exert the same force on the surface to be treated, so that the treatment carried out by the movable end is uniform over the entire surface of the subdivision, or to change the force exerted on the surface, to adapt the treatment to varying conditions.
    Preferentially, the method also comprises, between steps a) and b), a step a ') in which a chronological order of treatment of said subdivisions is determined. A step of determining the subdivision processing order makes it possible to optimize the displacements of the automaton and thus the duration of the treatment of the surface. Moreover, the automaton can thus limit movements on the ground, especially when working alongside people, in order to avoid any contact or interference with their work.
    Preferably, during step b), the platform and the base remain stationary, and / or, during step c), the processing means remains stationary. The movements of the automaton are deliberately programmed to be carried out separately from one another, ie: it is the platform and / or the base that move, or it is the means of treatment, but not both. same time. It then becomes easier for the people who can work around the automaton to anticipate and anticipate its movements, in order to act accordingly. Furthermore, the surface treatment method implemented by the automaton also allows, or even favors, a decorrelation of the movements of the automaton.
    Preferably, in step b), the processing means is displaced in a vertical and / or horizontal direction, and / or is oriented by rotation at least about an axis parallel to the surface to be treated, during the treatment of the area. As previously indicated, the processing means performs the work traditionally performed by the hand of a person; it is therefore planned to imitate as much as possible the movements of a hand, in order to reproduce as effectively as possible the technique implemented by a person.
    Preferably, at least one of the subdivisions of the surface to be treated comprises a peripheral contour delimiting an inner surface, and, in step b), the processing means is moved so as to first treat the peripheral contour and then the inner surface. of said subdivision. Such a method of implementation can be used in particular in painting: indeed, the method of rechampi vee / o \ i application of paint along the edges of the surface to be painted, before painting the painting. inside the surface. The automaton can therefore apply the same technique, at the level of each subdivision, to obtain a similar result.
    Preferably, during step b), the position of the treatment means relative to the surface to be treated is determined and monitored. The control method of the controller can thus include the control and management of different sensors to verify that the controller performs the correct surface treatment. Such a control can in particular be carried out on the distance separating the treatment means from the surface to be treated.
    Preferably, the treatment of a surface to be treated is a painting of said surface to be treated, a sanding of said surface to be treated and / or a projection of coating on said surface to be treated.
    Preferably, the surface to be treated comprises one or more walls, one or more facades, one or more ceilings and / or one or more floors. More precisely, the work that can be done by the automaton is not limited to a single continuous surface, but may comprise different surfaces identified and distinct from each other.
    According to another aspect, the invention also relates to an automaton for treating a surface to be treated, comprising: a base configured to move on a floor. a platform mounted on the base and configured to move, at least in part, perpendicular to the base, for example vertically, and a processing means, for example an arm, mounted on the platform and having a movable end configured to treat a given area.
    In particular, the automaton also comprises an electronic control unit configured to: a) divide the surface to be treated into subdivisions of area less than or equal to the given area, b) treat the surface of each subdivision by controlling the displacement of the treatment, and c) change subdivision by moving the platform, for example vertically, and / or by moving the base on the ground.
    Preferably, the automaton also comprises one or more location sensors in space and with respect to the surface to be treated, for example ultrasonic sensors, laser sensors, flight time sensors, video systems or even sensors with tags delimiting at least a portion of the surface to be treated. The purpose of the sensors is to favor the positioning of the automaton in its environment, in order to facilitate the identification of the surfaces to be treated, as well as the delimitation of said surfaces in space.
    Preferably, the automaton also comprises presence sensors and is configured to limit or even avoid contacts with potential obstacles, for example with people. Such sensors are intended in particular to preserve the physical integrity of people likely to work or be near the controller. Thus, thanks to the various sensors, the controller is configured to detect the presence of such people, and act accordingly so as not to hurt or annoy them. The automaton then becomes collaborative. since he can come to support people in their work, by doing his nearby. The term "collaborative" means an automaton able to work close to individuals, without barriers.
    Preferably, the automaton also comprises an interface configured to allow the input of instructions by an operator and / or the display of information relating to the operation of the automaton. Such an interface makes it possible in particular to control the automaton, and to give it instructions. In particular, insofar as the automaton is autonomous, the instructions are given to him at first, before leaving him alone to perform the programmed tasks.
    Brief description of the drawings The invention and its advantages will be better understood on reading the detailed description of a particular embodiment, taken by way of non-limiting example and illustrated by the appended drawings in which: FIG. a schematic perspective view of an automaton according to the present invention, - Figure 2 is an example of division into subdivisions of a surface to be treated, by the method according to the invention, and - Figure 3 is a flowchart of an exemplary mode of implementation of the method of treating a surface according to the invention.
    Detailed description of the invention
    FIG. 1 schematically illustrates a perspective view of a treatment automaton of a surface to be treated, according to the present invention. The automaton 1 thus comprises a base 2 for moving the automaton on the ground, and comprising: displacement means, in this case wheels 4, and a wheel drive means, for example an engine (not shown) The base 2 constitutes a frame for the PLC 1, and supports all the elements of the PLC 1 which are described below. The controller 1 also comprises a platform 6. The platform 6 is mounted on the base 2, for example via two rails 8 mounted substantially perpendicular to the base 2. The platform 6 is configured to move along the rails 8, that is to say substantially perpendicular to the base 2, by means of a drive means (not shown), for example a motor. A platform 6 is thus obtained which can move for example vertically to reach different heights of the surface to be treated. The automaton 1 also comprises a processing means, in this case an arm 10. The arm 10 is mounted on the platform 6 and comprises on the one hand a processing end 12 at which the tool is mounted. treatment of the surface 14, in this case a paint spray nozzle 14, and secondly one or more joints 16 connecting one or more arm portions 18. The joints 16 can move and orient the tool of treatment 14 as desired, over an entire area of given area. The area depends in particular on the length of the arm portions 18 and the amplitude of the joints 16. Moreover, the arm 10 also makes it possible to move the treatment tool 14 parallel to the surface to be treated, in order to obtain a result uniform treatment.
    Finally, the controller 1 comprises a control unit 20. The control unit 20 can be mounted on the base 2 of the controller 1, or be located remotely (relocated), or be partly mounted on the base 2 and partly relocated. The control unit 20 may in particular comprise a screen 21. The control unit 20 makes it possible to control the various means of the automaton 1, in particular the drive means of the base 2, the platform 6 and the arm 10. The commands are in particular determined by the control unit 20 according to the instructions and data that are communicated to it.
    More specifically, the electronic control unit 20 is configured to plan the treatment of the surface to be treated, taking into account the structure of the PLC 1, and facilitating the work of individuals near the PLC 1.
    Thus, the control unit 20 is configured to, initially, divide the surface to be treated into subdivisions of area less than or equal to the given area. In other words, the surface to be treated is subdivided into portions that can be treated individually only by moving the arm, the platform 6 and the base 2 remaining stationary. Then, the control unit is configured to treat the surface of each subdivision by controlling the movement of the arm 10. When the subdivision is processed, the electronic control unit 20 then commands to change subdivision by moving the platform 6 vertically, and / or by moving the base 2 on the ground. The automaton 1 thus works by subdivision, or cell, each subdivision corresponding to the surface that can be processed by the single movement of the arm 10 of the automaton 1. Then, the automaton 1 moves from subdivision to subdivision, by displacement of the platform 6 and / or the base 2.
    FIG. 2 illustrates an exemplary planning of the work to be performed to treat the entirety of a surface to be treated 22. More precisely, although the surface to be treated 22 is not a regular surface, it is considered by the electronic processing unit 20 as a set of subdivisions 24 whose areas are not equal to each other, due to the irregularity of the surface to be treated 22.
    The subdivisions 24 are obtained by cutting the surface to be treated 22 according to a regular grid whose lines correspond to the movements of the platform 6 and the base 2, in this case vertical and horizontal lines.
    Once the cutting of the surface to be treated 22 carried out by the control unit 20, it can then control the automaton 1 to successively treat said different subdivisions 24. Preferably, all the subdivisions 24 corresponding to the same position of the base 2, that is to say requiring only the displacement of the arm 10 and the platform 6, are treated successively. Then, the base 2 is moved to another position to successively treat all the corresponding subdivisions 24, and so on. In this way, the movements on the ground of the automaton 1 are limited, which favors the work of the automaton 1 with individuals nearby.
    Within each subdivision 24, the processing applied by the PLC 1 can also be planned, in particular to give a rendering close to that provided by a professional. For example, in the case of a painting treatment, the control unit 20 can be configured to control the treatment first of an edge or contour of the surface to be treated 22: such treatment does not occur. applies only where the subdivision in question is positioned at the edge of the surface to be treated 22, and is irrelevant if the subdivision in question is entirely surrounded by other subdivisions 24. Such a method corresponds to rechampi, a technique consisting of first work the contours of the surface before working the center.
    Once the contour is achieved, the control unit 20 can then control the arm 10 so as to process the remainder of the area of the subdivision 24, that is to say the interior of the subdivision 24. For this work , the control unit 20 may in particular provide for a displacement of the arm 10 in a horizontal or vertical grid, that is to say, to treat the interior of the subdivision 24 along certain contour lines of said subdivision 24 (horizontal contours or vertical).
    Similarly, when the subdivision 24 comprises a particular element, such as a switch or an electrical outlet, the same technique can be used: the control unit 20 can be configured to perform the treatment along the contour of the particular element, before processing between the particular element and the contour of subdivision 24.
    When all the subdivisions 24 are processed, the automaton 1 can then stop. It should be noted that in the example described above, the surface to be treated 22 is a single surface. However, the work of the machine 1 according to the invention does not stop at such surfaces, but can treat a surface to be treated with several separate and separate parts and each other. In this case, each part of the surface to be treated is worked as indicated above, that is to say is specifically divided into subdivisions that are worked successively. When a part is finished, the control unit 20 controls the base 2 and / or the platform 6 so as to move to another non-treated part of the surface to be treated.
    Such a displacement can in particular operate, in practice, on the one hand by attributing to each distinct part of the surface to be treated, a specific reference work used by the controller 1 for the treatment of said distinct part of surface, and on the other hand by positioning, in a single global repository, the different specific reference frames of work between them, in order to allow the automaton 1 to move from a distinct part of the surface to be treated to another distinct part of the surface to be treated. For example, the different surface portions to be treated may be two walls of a room, for example two walls contiguous but having an angle between them, or two parallel walls distant facing each other. In both cases, the controller 1 is forced to reorient with respect to the portion of the surface to be treated, as it passes from one surface portion to another, before starting the treatment of said surface portion. The control unit 20 may also allow an operator to specify the tasks to be performed and their parameters, as well as to be aware of the various status messages or alerts detected by the control unit 20. Thus, the unit of command 20 can allow the operator to specify: the processing parameters, for example sanding (speed, effort, ...), or painting (number of layers to apply, type of paint, quantity of paint, pattern, interlacing of layers, overlapping of two contiguous passes, ...); the different areas of the surface to be treated, especially when the treatment parameters must not be uniform over the entire surface to be treated, but must change according to determined data. The control unit 20 can also be used to define the surface to be treated, and in particular to position it in space so that the PLC 1 can identify and delimit it.
    In order to allow the controller 1 to locate and move in space to treat the different surfaces, it may include sensors. The sensors can be of different technologies, depending on the amplitude and / or the precision of the distances concerned. Thus, the automaton 1 can comprise two distance sensors, for example ultrasonic sensors, mounted in the treatment plane of the arm 10 and making it possible to determine, on the one hand, the distance between the surface to be treated and the controller 1, and on the other hand the angle between the axis of the automaton 1 and the surface to be treated. This ensures, thanks to these sensors, that the arm 10 performs the treatment well at the right distance from the surface to be treated, and by moving parallel thereto.
    Alternatively, when the treatment requires contact with the surface to be treated, for example a sanding, the determination of the distance to the surface to be treated, and optionally the angle between the axis of the controller 1 and the surface to be treated, can be directly evaluated by the treatment tool, from internal resistance sensors used to control the force applied to the surface to be treated. The automaton 1 may also include flight time sensors, for example laser sensors, to control the position of the controller 1 in its environment. For this purpose, beacons can also be positioned at different locations identified by the controller 1, to ensure that it is well in front of the surface portion to be treated. Such sensors also make it possible to ensure that the movements of the base 2 are parallel to the surface to be treated, so that the junctions between the different subdivisions 24 coincide.
    Alternatively, it is also possible to provide, in addition to sensors or as a replacement for sensors, one or more cameras allowing the controller 1 to position itself in its environment in three dimensions. Thus, two stereoscopically positioned cameras can allow the control unit 20 to be in space by determining the distance and the angle separating the controller 1 from the surfaces to be treated or the surfaces delimiting its moving environment. This may also allow the automaton 1 to move from one part of the surface to be treated to another, when these are distinct and separated from one another, as described above.
    In all cases, a preliminary step of identifying the surface to be treated in the environment detectable by the PLC 1, as well as a calibration of the initial position of the PLC 1 in its environment, may be necessary for the implementation of the positioning and positioning steps during the treatment of the surface to be treated.
    Finally, the controller 1 may also include presence sensors, to ensure that the controller 1 can work close to individuals without hitting or injuring them. For example. the automaton 1 may comprise optical sensors forming a barrier between the evolution zone of the automaton 1, and more particularly the evolution zone of the platform 6 and the arm 10, and the rest of the part. Thus, in the event of detection of an intrusion of an object in said zone of evolution, the control of the platform 6 and the arm 10 can be interrupted in order to ensure that it does not injure anyone or damage the PLC 1. Furthermore, or alternatively, the control unit 20 can monitor the control of the various means of movement of the controller 1, for example those of the base 2 or the platform 6, in order to detect a possible obstruction to a displacement command. In this case, the command can be stopped, or even reversed, and the controller 1 can wait until a person comes to check the reasons for the obstruction. It is then ensured that the automaton 1 can actually evolve in the middle of individuals without the risk of hurting them.
    FIG. 3 illustrates a flowchart of an exemplary method 26 for treating a surface to be treated by the PLC 1 described above. The method 26 firstly comprises a first step 28 in which the area to be treated is divided into subdivisions of area less than or equal to the given area. Then in a second step 30, a chronological order of treatment of said subdivisions is determined. In step 32, the surface of each subdivision is treated by displacement of the arm of the automaton, and in step 34, subdivision is changed by vertical translation of the platform and / or displacement of the base on the ground. .
    Thus, thanks to the invention, it becomes possible to treat, with the aid of an automaton, a surface to be treated, while allowing individuals to intervene in the vicinity of the automaton. In particular, even if the machine is autonomous, the movements of it are planned to limit problems with people working nearby. The automaton can thus serve as an assistant within a construction site, in order to perform in particular the most repetitive tasks and without particular technicality. It may in particular perform a painting treatment, for example by spraying paint on the surface, or sanding, for example by rotating an abrasive means to the surface to be treated, or even the application of coating, by example by projection.
