Definitions
- the present invention relates to a method and system for operating a robot and a computer program or computer program product for carrying out the method.
- Robots have various components, for example kinematic structural bodies, drive motors, gears, brakes, bearings, sensors and the like, which each have different load limits with regard to different loads and are also loaded differently depending on the current pose and movement of the robot.
- the object of the present invention is to improve the operation of a robot.
- Claims 13, 14 represent a system or computer program or
- a robot which in one embodiment has a robot arm, in one embodiment is a robot arm, has several, preferably at least three, in one embodiment at least six, in one embodiment at least seven, joints, in one embodiment swivel joints, on which are adjustable or adjusted by, preferably electric, joint drives in order to cause the robot to move.
- a current one- or multi-dimensional load value is determined for the respective joint or joint-specific; and based on this current load magnitude value and a one- or multi-dimensional predetermined limit value for the respective joint, in one embodiment based on a difference between the limit and load magnitude value for the respective joint, a one- or multi-dimensional load value is determined for the respective joint or joint-specific .
- components or dimensions of the load magnitude values, limit values and load values are assigned to one another in one embodiment, preferably in such a way that the component j of the load value for the joint i is based on the corresponding dimension or component j of the load magnitude value for the Joint i and the corresponding dimension or component j of the limit value for joint i is determined or in general form:
- B(i,j) Component j of the load value for joint i
- L(i,j) Component j of the load magnitude value for joint i
- G(i,j) component j of the limit value for joint i;
- the limit value is or is specified in one embodiment (in each case) based on permissible loads of one or more components, in particular at least one kinematics structural body, drive motor, bearing, sensor, gear and/or at least one brake, of the robot.
- One embodiment of the present invention is based on the idea of specifying joint or axle-specific limit values for various components based on permissible loads and comparing current values with these. In this way, it can be determined in which joints or axes loads are currently how far away from their permissible maximum values, and an advantageous reaction can be made to this in order to influence the operation of the robot, preferably to avoid unwanted overloads.
- the load magnitude value and/or load value for a joint depends (in each case) on a torque at the (respective) joint; in particular, a component of the load value can indicate such a torque.
- mechanical loads can be advantageously taken into account in one embodiment.
- the load magnitude value and/or load value for a joint in one embodiment depends (in each case) on a speed at the (respective) joint; in particular, a component of the load value can indicate such a speed.
- dynamic loads can be advantageously taken into account in one embodiment.
- the load magnitude value and/or load value for a joint depends on both a torque and a speed at the (respective) joint.
- the load magnitude value and/or load value in particular a component of the load magnitude value or load value, can depend on, and in particular indicate, a product of torque and (rotational) speed, in particular a power.
- wear can be advantageously taken into account in one embodiment.
- the multidimensional load value can be a component that depends on a torque at the (respective) joint, this in particular, and / or a component that depends on speed at the (respective) joint, this in particular and/or have a component that depends on a product of torque at the (respective) joint and speed at the (respective) joint, indicates this in particular. This means that different loads can advantageously be taken into account together.
- a torque or a speed at a joint includes a torque or a speed between two mutually rotatable members of the joint, in particular a torque or a speed of a joint drive, in particular a motor and/or gearbox, of the joint, and/or between two mutually rotatable structural members of the joint.
- At least one component of the load magnitude values for the joints is measured by the corresponding sensors, for example torques by torque sensors and/or (rotational) speeds by (rotational) speed sensors, with the measured values being further processed in a further development, for example by filtering, averaging , smoothing, scaling or the like.
- load magnitude or load values can be determined precisely in one version.
- At least one component of the load magnitude values for the joints is determined based on a mathematical model or observer, for example torques using a model or observer based on measured positions, speeds, temperatures, currents and / or voltages of drive motors or the like.
- a mathematical model or observer for example torques using a model or observer based on measured positions, speeds, temperatures, currents and / or voltages of drive motors or the like.
- an action of the robot is carried out to reduce one or more components of the load values or with the proviso or in such a way that (through this action) these component(s) are reduced.
- One embodiment of the present invention is therefore based on the idea of carrying out different actions depending on how far the loads in the individual joints of the robot are from their permissible limit values, thereby preferably preventing unwanted overloading of the robot to be avoided if possible. In this way, the robot can be brought closer to its permissible joint- and component-specific load limits in one version, thereby improving its operation.
- a load situation of the robot is signaled based on the load values, in one embodiment optically and /or acoustically to an operator who cooperates with the robot in one execution, and/or data-technically to an application program, which in a further development in response to this causes the robot to carry out an application program-specific (predetermined action, in one execution an action).
- the load values temporarily exceed specified limit values.
- signaling a load situation of the robot is according to an embodiment of the present Invention based on the load values, a load situation of the robot is stored and, in a further development, the stored load situation of the robot after execution of at least one work process, in one embodiment after execution of several process cycles, of the robot, during which the load size values have been determined, for an analysis , in particular damage and/or wear analysis.
- the idea behind this is to document during operation whether, when and/or how long and/or how often which components or joints (how) have been operated close to their respective load limits or, if necessary, have exceeded them. This can be used advantageously, in particular, for predictive maintenance, to clarify damage to the robot and/or to plan future work processes.
- an action of the robot which without limitation of generality is also referred to as the first action and in particular can be one of the actions described here, in particular a speed reduction, evasive movement or the like, and/or another action, is carried out , if a component of the load values, which is also referred to as the first component without loss of generality, lies in a predetermined range, which is also referred to as the first range without loss of generality, an action to reduce this (first) component in one execution Load values.
- another action of the robot which is also referred to as a second action without limiting generality, and in particular one (other) of the actions described here, in particular a speed reduction, evasive movement or the like, and/or another action,
- another action can be carried out to reduce the one or first component of the load values.
- a disruption to or an intervention in a working operation(s) of the robot can be advantageously reduced.
- an action of the robot is carried out when another component of the load values, which is also referred to as the second component without limiting generality, is in a predetermined range, in one embodiment in the one or first predetermined one area or another specified one area, lies.
- This action can in particular be one of the actions described here, in particular a speed reduction, evasive movement or the like, and/or another action. It can be an action to reduce this other or second component.
- it it is the one or first action
- another execution is a different action or action different from the one or first action, which is also referred to as the second action without loss of generality.
- the one or first action and/or the other or second action is or is predetermined by the application program to which the load situation of the robot is signaled and which, in response thereto, causes the robot to perform one or more of these application program-specific actions To carry out an action, wherein the action is or is selected from several predetermined actions in one execution based on user input.
- the robot can react in a particularly suitable manner to stressful situations depending on the application program or the user can specify particularly suitable reactions of the robot to signaled stressful situations by appropriate input or configuration of the application program or the action(s) through or in the application program, so that a particularly advantageous operation of the robot can be realized.
- the robot in one version reacts specifically to different loads or load situations and can thus preferably avoid or reduce overloads in a more targeted manner.
- the robot can react in different applications or when executing different application programs in a manner specific to both the application (program) and the load value components and can thus avoid or reduce overloads particularly well in one embodiment, whereby, as explained elsewhere, overloads are also accepted in a specific application program manner can be taken.
- the one or first and other or second components can be both components of the load value for be the same joint.
- the robot can react differently to avoid or reduce overload either through a torque or through a speed of the joint, depending on which component of the corresponding load magnitude value is closer to a permissible maximum value.
- the one or first and other or second components can also be components of load values for different joints.
- the robot may react differently to avoid or reduce either an overload caused by a torque of one joint or an overload caused by a torque or speed of another joint, depending on which component of the corresponding load magnitude value is closer to an allowable maximum value .
- the load value for a joint (each) has one or more current or momentary components. This is particularly advantageous in order to reduce load values during operation of the robot, in particular to avoid selective overloads due to peak loads, through an action of the robot that is determined or specified based on these current components.
- the load value for a joint in one embodiment has one or more single or multiple time-integrated components. This is particularly advantageous in order to carry out an analysis after completing at least one work process, in one embodiment after completing several process cycles, and/or to signal a load situation on the robot, since in this way a cumulative load on the robot can be advantageously taken into account.
- an action by the robot that is determined or specified based on such time-integrated components can also reduce load values during operation of the robot or current components can also be signaled, for example so that a user or application program can intervene during operation. or saved, for example, so that maximum values can be used for analysis.
- a time-integrated component is determined in one embodiment for a predetermined time interval, in one embodiment since a predetermined point in time, for example commissioning, maintenance or the like, and/or for a predetermined period of time, in one embodiment a predetermined period of time up to a current or current time, for example for the last 1, 5 or 10 seconds or the like.
- a time integration to form a time-integrated component only current load magnitude values or load magnitude value components are taken into account that have at least a predetermined minimum amount, which in one embodiment is or is predetermined based on the corresponding limit value or the corresponding limit value component.
- cumulative loads can be taken into account particularly well in one embodiment, in particular in addition to or as an alternative to an acute overload caused by a current peak load, a cumulative overload can be taken into account by a corresponding load collective.
- a speed of the robot that is predetermined, in particular in a work program, in particular when traveling along a path that has already been determined before the current load value values or by the work program is determined, is reduced in order to reduce at least one component of the load values.
- this predetermined speed is a path speed or speed of a robot-fixed reference, in particular an end effector and/or TCP.
- a load on the robot or a corresponding component of the load values can be reduced in a simple and/or safe manner.
- the robot continues to follow the specified path (“track-true”) during this speed reduction, preferably with its robot-fixed reference. Additionally or alternatively, the robot stops at this speed reduction (if applicable). As a result, in one embodiment, the predetermined path can then advantageously be traveled further. Additionally or alternatively, particularly safe behavior of the robot can be achieved in one embodiment.
- the robot in addition or as an alternative to a speed reduction, in a further development after the aforementioned speed reduction, the robot carries out an evasive movement that is dependent on the load values in order to reduce at least one component of the load values.
- the robot preferably with its robot-fixed reference, deviates during this evasive movement from a path specified in one embodiment before the current load value values are determined or by the work program.
- such an evasive movement makes it possible to react particularly advantageously to (imminent) overload or to avoid or reduce it.
- the speed reduction and evasive movement can be combined with one another in a particularly advantageous manner, in that in one embodiment the robot is first braked, preferably along the path, if necessary until it comes to a standstill. (Only) if this is not enough to sufficiently reduce the load values, does the robot carry out an evasive movement in which it deviates from the path in one execution.
- the avoidance movement has, in particular can be, a movement of the robot anti-parallel to a projection, in particular transformation, of load values to be reduced into a Cartesian work space of the robot.
- the (components of the) load values correspond to loads at the joint level and can thus be transformed from the joint into the Cartesian working space of the robot in a similar way to a known forward transformation.
- the Cartesian working space of the robot in the sense of the present invention comprises the, in particular one-, two- or three-dimensional space of a position of a or the robot-fixed reference, in particular an end effector or TCP of the robot, and / or the, in particular a , two- or three-dimensional space of an orientation of the robot-fixed reference, whereby Denavit-Hartenberg descriptions, quaterion descriptions and the like can of course also be understood as a Cartesian work space of the robot in the sense of the present invention.
- a robot-fixed reference preferably an end effector or TCP, of the robot is further predetermined by one, in one embodiment, the or one of the above-mentioned path(s). Execution is held in a predetermined position before determining the current load size values or the path predetermined by the work program, whereby in a further development an orientation of the robot-fixed reference predetermined by this path is abandoned during the evasive movement.
- the robot-fixed reference is held at the specified location during the avoidance movement, but is rotated in order to avoid an overload situation. This means that a work process is disrupted to a small extent in one execution.
- a robot-fixed reference preferably an end effector or TCP, of the robot is further predetermined by one, in one embodiment, the or one of the above-mentioned path(s).
- Execution maintains a predetermined orientation before determining the current load size values or the path predetermined by the work program, whereby in a further development a position of the robot-fixed reference predetermined by this path is abandoned during the evasive movement.
- the robot-fixed reference is held in the predetermined orientation during the avoidance movement, but is shifted to avoid an overload situation to avoid.
- a thrust direction of a robot end effector or tool can advantageously be maintained and a work process can thus be advantageously continued.
- Both versions are combined with one another in a further development by exploiting a kinematic redundancy of the robot in one version and, during the avoidance movement, a robot-fixed reference, preferably an end effector or TCP, of the robot is further used in one version by one of the above mentioned, predetermined path(s), in one embodiment a path, predetermined position and orientation predetermined before determining the current load size values or by the work program is maintained.
- a work process can be advantageously continued in one embodiment.
- a predetermined speed of the robot is reduced in order to reduce at least one component of the load values, reduced in this way in one embodiment that the robot continues to follow the specified path and/or stops during this speed reduction;
- the robot in one embodiment after this speed reduction or also according to an independent aspect, carries out an evasive movement dependent on the load values in order to reduce at least one component of the load values.
- a robot-fixed reference of the robot is further held in a position that is predetermined by the path that was predetermined before the current load size values were determined, an orientation of the robot-fixed reference predetermined by this path being abandoned; or b2) during the evasive movement, a robot-fixed reference of the robot is further held in an orientation that is predetermined by the path that was predetermined before the current load size values were determined, a position of the robot-fixed reference predetermined by this path being abandoned; or b3) during the evasive movement, by exploiting a kinematic redundancy of the robot, a robot-fixed reference of the robot is further held in a position and orientation that is specified by the path that was specified before the current load size values were determined.
- an emergency stop of the robot is carried out, preferably after carrying out the above-mentioned aspect a) and/or b), in particular b1), b2) or b3), in which, in one embodiment, the brakes of the robot are closed.
- a system for operating the robot in particular hardware and/or software, in one embodiment programmatically, is set up to carry out a method described here and/or has:
- system or its means has:
- a system and/or a means in the sense of the present invention can be designed in terms of hardware and/or software, in particular at least one, preferably data or signal-connected, in particular digital, processing, in particular microprocessor unit (CPU), graphics card (GPU) or the like with a memory and / or bus system, and / or have one or more programs or program modules.
- the processing unit can be designed to process commands that are implemented as a program stored in a memory system, to detect input signals from a data bus and/or to deliver output signals to a data bus.
- a storage system can have one or more, in particular different, storage media, in particular optical, magnetic, solid-state and/or other non-volatile media.
- a computer program product can have, in particular, a storage medium, in particular a computer-readable and/or non-transitory storage medium, for storing a program or instructions or with a program or with instructions stored thereon.
- executing this program or these instructions by a system or a controller causes the system or the controller, in particular the computer or computers, to implement a method described here or to carry out one or more of its steps, or the program or the instructions are set up for this purpose.
- one or more, in particular all, steps of the method are carried out completely or partially automatically, in particular by the system or its means.
- the system includes the robot and/or the application program.
- the present invention is particularly suitable for operation of the robot in which it cooperates with at least one human during the movement caused by joint drives, since unforeseen loads can often occur, for example because a human exerts unexpected forces on the robot. Further advantages and features result from the subclaims and the exemplary embodiments. This shows, partly schematized:
- Fig. 1 a system for operating a robot according to an embodiment of the present invention.
- Fig. 2 a method for operating the robot according to an embodiment of the present invention.
- Fig. 1 shows a system for operating a robot 1, which has several joints, of which, for example, a carousel joint 11, a wrist 15 and a rocker joint 12 as well as a rocker joint drive 12.1 and a sensor arrangement 12.2 with a torque sensor and a speed sensor are identified with reference numbers.
- Speeds of the joints or drives are indicated by ni , ... , n 6 , a control by reference number 2 and an end effector of the robot by reference number 17 .
- FIG. 2 illustrates a method carried out by the controller 2 or the system for operating the robot 1 according to an embodiment of the present invention.
- a three-dimensional load value [BTi, BNi, BPi] for the respective joint i is determined based on these load size values and a predetermined three-dimensional limit value [TMi, NMi, PM for the respective joint i. This can in particular be the difference between the current values and limit values. Additionally or alternatively, time integrals can also be used.
- a load situation of the robot is signaled and/or saved based on these load values before the method or the controller 2 returns to step S10. An application program can react to this signal in a specific way. Additionally or alternatively, a damage event can then be analyzed based on the stored load values.
- an action by the robot to reduce one or more components of these load values is carried out based on the load values.
- a step S40 it is checked whether one of the load values is in a predetermined range, for example one of the components of [BT i, BNi, BPi] standardized to 1 is at least 0.9, i.e. at least 90% of a permissible one for the respective joint Load, for example a torque permissible for this joint, a speed permissible for this joint or a power permissible for this joint. If this is not the case (S40: “N”), the method or control 2 returns to step S10.
- step S50 the speed specified for traveling along the path is reduced according to the path, if necessary until the robot stops on the specified path.
- the robot 1 carries out an evasive movement in a step S70.
- step S90 If this is sufficient so that none of the load values no longer fulfills the criterion (S80: “Y”), the method or control 2 also returns to step S10. Otherwise (S80: “N”), an emergency stop of the robot is carried out in step S90.
- step S10 When returning to step S10, if necessary, the reduced speed is increased again to the predetermined speed (step S55) and/or through Reversal of the evasive movement returned to the specified path (step S75).
- steps S30 and S40-S90 were shown together in FIG. 2, although step S30 or one or more of steps S40-S90 can of course also be omitted.
- the application program may implement one or more of steps S40-S90 in step S30.
- Examples of components of a robot whose load limits can be used to specify the limit values are, in particular, motors, gears, brakes, torque sensors, bearings and structural components or joint bodies.
- Monitoring the load situation can generate warnings or signals in a user program in such a way that the overload situation can be prevented, or in such a way that the overload situation is possibly consciously addressed, with the service life of the robot being deliberately shortened. Additionally or alternatively, entries can be made in a log file in which the overload is recorded for later viewing.
- the axis or joint-specific configuration or storage of the limit values or nominal “maximum ratings” can be done in vector form, as can the processing of the load magnitude values or load value.
- Unexpected stress situations can advantageously be taken into account, such as can occur in particular in human-robot collaboration/cooperation applications, for example when a human pulls on the robot while it is executing a predetermined path movement.
- the stress values can in particular have the following components: a) acute or momentary stress. This acute situation is signaled to the application in a prioritized manner and/or is digitally documented in a, preferably persistent, file; b) integral load: Even if the robot is operated just below its load limit for a longer period of time, its service life decreases. Therefore, in one embodiment, the invention also offers an indication of the components that are subject to the greatest wear in continuous operation, preferably without triggering an acute situation.
- load integrals are created for all joints and made available to the user for evaluation. In particular, this can be implemented as follows: For each joint, a percentage limit is defined and stored in relation to a stored static upper limit, from which the joint should be monitored, for example 90% of the maximum permissible load.
- the current load contributes to the formation of an integral.
- the contribution can also be non-linear, for example as follows: M is a current torque of a joint, Mx is the limit value stored for this. Then in During execution, a time integral is formed using the term (
- -80%*Mx) 2 , which only contributes to the integral if the amount of M is also greater than 90%. So B f [(
- B and S are provided in one version within the controller per joint for the application developer. This gives the user a quantitative expression for the mechanical stress to which they subject their robot.
- B and S are preferably each vectors over the quantities to be considered. If you subtract from the current B(t) a B(tx) from the past time (which existed x seconds ago), then you get a picture of the load situation in the time tx to t. This allows you to advantageously ignore long-ago stress periods and (B(t)-B(tx))/x gives an advantageous measure of the stress situation of the robot in the last x seconds. With these tools you can easily find out at which points in a program flow the movements can perhaps be “defused” in order to extend the life of the robot.
- Acute overload situations are signaled in one execution via a call-back call to a function that the user or programmer can define in order to achieve their own behavior or an interrupt immediately upon detection in the application.
- the application can then react quickly and individually to this.
- An advantageous aspect lies in providing the load situation in the form of a data structure that can be read by the user program: all current vectors with the percentages of the current loads per axis or joint. From these vectors you can directly see which values are critical at the axis or joint level, for example torque, speed or power. Vectors can also be transformed forward into Cartesian space from these axis or joint values, with which the user or programmer can use the Application can easily recognize which countermeasures should ideally be taken in the event of an impending load situation in order to Cartesianly avoid the overload situation. The load magnitude vector points in the Cartesian direction in which the load would increase the most.
- the Cartesian forward-transformed vector for the torque load situation points in the direction in which the current axle or joint load would become even greater.
- its amount can be calculated as a percentage of the maximum load. If the robot's end effector were then pulled in this direction, the load would continue to increase. Conversely, the situation can be relaxed if the end effector is pressed in the opposite direction.
- the application developer can design his application in such a way that the robot independently stays away from overload situations in permissible situations.
- At least one of the following countermeasures is preferably carried out: a) Emergency stop: The robot interrupts its work and switches to emergency stop, with braking. b) Path faithful overload avoidance: The control is set programmatically so that it automatically reduces the speed and tries to to prevent the overload situation without leaving the programmed path. If the overload cannot be circumvented, the robot will ultimately stop, but without initially triggering an emergency stop. If the situation clears up (for example through support through human interaction from outside or mechanical relief, or program-controlled actions), then the robot continues its work while adhering to the limit values. It can also reach the target speed again. The speed is preferably used as a controlled variable here in order to avoid an overload situation.
- Path-true avoidance in defined redundancies The control is set programmatically so that it automatically avoids the load and thereby tries to avoid the overload situation.
- User-specific behavior The controller can be set programmatically to signal the user program that the robot is (potentially) overloaded, and the application can itself implement a treatment strategy. This method offers maximum flexibility, whereby short overload situations are consciously accepted, even if the robot repairs more quickly must become. This can still be the cheapest solution.
