摘要： A method for processing a moving workpiece (1), in particular a vehicle body (1) which is moved using of a conveyor belt (10). A processing tool (5) is used which is attached to the hand (12) of a robot (7) and comprises a sensor system (18) which is permanently connected to the processing tool (5) and has at least one sensor (19). During the processing, the processing tool (5) follows the moving workpiece. This following movement is based on a closed-loop control process in which the processing tool (5) is oriented periodically towards reference areas (9) of the moving workpiece (1) using measured data of the sensor system (18). The measured data of the sensor system (18) is compared with setpoint data which is generated within the scope of a set up phase (I) of the processing tool (5), and a movement vector of the processing tool (5) is calculated from the difference between the measured values and setpoint data using a Jacobi matrix calculated within the scope of the set up phase, the processing tool (5) being moved by an amount equal to said movement vector. This process is repeated in a control loop.

摘要： A method for producing a connection area (4) on a work piece (1), in particular on a vehicle body plate which is to be positioned precisely with respect to a reference area (8) on the work piece (1). A robot-guided processing tool (9) is used which is permanently connected to a sensor system (13) and forms a tool/sensor combination (16) with it. In a first step, the tool/sensor combination (16) is moved, within the scope of a positioning phase (II), from a proximity position (24) which is independent of the position of the work piece (1) in the working space (23) of the robot (11), into a preliminary position (18) in which the tool/sensor combination (16) is oriented precisely with respect to the reference area (8) of the work piece (1). To move to the preliminary position (18), an iterative closed-loop control process is run through, in the course of which firstly an (actual) measured value of the sensor system (13) is generated and compared with a (setpoint) measured value generated within the scope of a setup phase. A movement vector of the tool/sensor combination (16) is calculated from the difference between the (actual) measured value and (setpoint) measured value using a Jacobi matrix which is calculated within the scope of the setup phase, and the tool/sensor combination (16) is moved by an amount equal to this movement vector. To carry out this positioning task it is possible to dispense with a metric calibration of the tool/sensor combination (16).

摘要： During welding with high output power, the gaps between the pieces being joined may not exceed a maximal gap width. It is the task of the present invention to provide a process for laser beam welding, which on the one hand ensures maintaining (not exceeding) a maximal gap width between the sheets and on the other hand makes possible a maximal utilization of the achievable welding speed. This task is solved in that the sheets, prior to welding, are first spot welded, wherein they are clamped only during this spot welding in order to ensure the maintenance of a maximum gap width.

摘要： A method for the mounting of an add-on part (3) on a workpiece (1), in particular on a vehicle body, the intention being for the add-on part (3) to be aligned on the workpiece (1) in a precisely positioned manner in relation to a reference region (12, 13). Use is made of a robot-guided mounting tool (5) which is connected fixedly to a sensor system (20). In order to achieve the precisely positioned alignment of the add-on part (3), an iterative control operation is run through, in the course of which first of all an (actual) measured value of the sensor system (20) is produced and is compared with a (desired) measured value produced within the context of a setting-up phase. A movement vector of the mounting tool (5) is calculated from the difference between the (actual) measured value and (desired) measured value using a Jacobi matrix calculated within the context of the setting-up phase, and the mounting tool (5) with the add-on part (3) fixed therein is iteratively displaced in relation to the workpiece (1) by these movement vectors until the desired position is reached. This positioning task can be resolved without a metric calibration of the sensor system (20).

摘要： A vehicle-useful, high-resolution 3D-detection of the environment of a street vehicle with environment scanning sensors is not possible today. Depending on application the first commercially available vehicle integrated systems may be a comprise between resolution of the sensors and size of the sampled area. With the inventive two dimensional distance resolution sensor device it becomes possible, in contrast to those which are known, to produce a system which, installed in a street vehicle, detects and preferably processes complex dynamics scenarios such for example street traffic, from the prospective of the active dynamic moving vehicle. Therein a three dimensional image of the environment is produced using a distance sensor, which produces a two dimensional distance profile (depth profile), and on the other hand, using a data processing and a storage unit, which process and store sequential distance profiles and sequence a series of distance profiles into the three dimensional image of the environment.
