- Fig. 1 a system for checking a predetermined path of a robot according to an embodiment of the present invention.
- Fig. 2 a convex hull of a portion of a path of a robot according to an embodiment of the present invention.
- Fig. 3 a method for checking the predetermined path of the robot according to an embodiment of the present invention.
- Fig. 1 shows a system for checking a predetermined path of a robot 1 using a visualization device in the form of an AR device 2 or a tablet 3 by a test person 4.
- FIG. 2 shows a robot 1 that performs a movement with part of its limbs that runs along a section of a predetermined path.
- the movement is discretely represented in time-successive poses together result in the movement along the section of the specified path.
- the movement is shown as a convex hull 8 and an imaginary hull 9 spaced from the convex hull. Both the convex hull 8 and the imaginary hull 9 have an intersection with the environment 6.
- the existence of an intersection can be represented by issuing a warning, particularly a visual warning. Based on the warning, a test person can, for example, modify the specified path until a path is found that does not intersect with the environment 6 and accordingly no warning is issued.
- a real environment 6 of the robot is created using a detection device 5A or 5B arranged on the visualization device 2 or 3, preferably integrated or detachable, for example a 3D camera system, lidar sensor or the like recorded and in a step S20 a computer-implemented environment model is determined using this data.
- the environment model can additionally or alternatively be created on the basis of target data of the environment or can only be provided, for example retrieved from a memory.
- a step S30 an intersection between a computer-implemented model of the robot and the environmental model is determined for various sections, in one embodiment points, of the convex hull, in particular the imaginary hull, of the path, the path being determined, for example, using a simulated environment or by teaching or teaching was specified.
- the robot model can have geometry primitives in the form of cuboids, cylinders or the like, which are each assigned to one of the movable members of the robot and whose pose or position changes accordingly according to the respective section or path point or when the robot simulates the path changes.
- the environment model can, for example, have a grid or an approximation surface that approximates a point cloud captured when capturing the real environment. The minimum distance between all these geometry primitives and the grid or the approximation surface is then determined as the distance between the robot and the environment model. As an intersection between robot and The environment model is then used to determine, for example, an overlap between all of these geometry primitives and the grid or the approximation surface, or points, in particular volumes, that are simultaneously occupied by the robot model and the environment model.
- a virtual representation of the convex shell of the path is visualized using the visualization device 2 or 3 in an augmented reality for testing the path, for example a shell around the poses of the robot or its model (via the time), whereby the hull can be or is a convex hull or where the hull can be or is an imaginary hull, which is in particular spaced from the convex hull.
- a warning is issued for a section of the path if an intersection exists for this section, in particular if the distance determined for this section between the convex hull, in particular the imaginary hull, and the environmental model is in a predetermined warning range, and for an all-clear is issued for a section of the path if there is no intersection for this section, in particular if the distance determined for this section is in a predetermined all-clear range, for example in the manner described above by highlighting corresponding sections or the like.
- test person 4 can check in step S40 whether there is a risk of the robot 1 colliding with the environment when traveling along the specified path or how great this is.
- step S50 It can advantageously limit or concentrate on the sections for which a warning is issued, check them more closely and, if necessary, modify the path, especially in such sections, in a step S50, whereupon steps S30, S40 and If necessary, S50 can be carried out again.
- the tested path can be traversed with the real robot in a step S60.
