Abstract: In order to be able to automatically eliminate discrepancies, arising in the course of the configuration of a robot-object system environment, between the reality of the robot-object system environment and its digital representation as a CAD model, without manual on-site commissioning of the robot-object system environment with adaptation of the CAD model to the reality, the following is proposed for configuring a robot-object system environment having at least one object and having a robot for object manipulation and object sensing: synchronizing a digital robot twin, which digitally represents the robot-object system environment and controls the robot for the object manipulation on the basis of a control program, for expedient use of the robot in the robot-object system environment during the object manipulation, appropriately and, in this regard, in one or two stages.

Abstract: In order to control a technical system, a user control variable is read in and a plurality of control variable variants of the user control variable are generated. A respective trajectory of the technical system is extrapolated for the user control variable and for the control variable variants, for which a respective reliability is evaluated. Furthermore, a respective distance of each control variable variant to the user control variable is determined. The user control variable is then selected as a control signal for the technical system in the event that the trajectory extrapolated for the user control variable is evaluated as reliable. Otherwise, a control variable variant with an extrapolated trajectory evaluated as reliable is selected from the control variable variants as a control signal, wherein a control variable variant with a low distance is preferably selected. Finally, the control signal for controlling the technical system is emitted.

Abstract: A method for determining an N+1-dimensional environmental model is provided. According to the method, environmental information in N dimensions is determined using a sensor. In a further step, position and/or orientation of the sensor is/are determined. Then, the N+1-dimensional environmental model is determined based on the determined environmental information in N dimensions and the determined position and/or orientation of the sensor. Further, a device and a mining apparatus are provided.

Abstract: In order for a multiplicity of components of the same type to be fastened by bracing by means of dissimilar caulking pieces, a first component by an actuator is braced in a force-fitting manner in relation to a first caulking piece. A first bracing parameter herein is measured by a first sensor during the bracing procedure. A second caulking piece is then selected so as to depend on the first bracing parameter, a second component by the actuator being braced in a force-fitting manner in relation to said second caulking piece.

Abstract: A method for calibrating a first movable part of a crane. Position a first crane part above a calibration point at a first predetermined co-ordinate in a reference system. Measure a first distance between a first transmitter/receiver element of a first distance measuring device mounted on the first movable crane part and a second transmitter/receiver element of the first distance measuring device disposed in a stationary manner in the reference system. Measure an orientation of the first transmitter/receiver element in accordance with the first predetermined co-ordinate, the measured first distance and a first item of information concerning the surroundings. Perform a transformation in the reference system in accordance with the ascertained orientation of the first transmitter/receiver element for transforming distance measured during operating of the crane by means of the first and second transmitter/receiver elements to determine a position of the first movable crane part.
