Abstract: A gripper device for an object and a changing robot having such a gripper device. The gripper device includes a housing having an inner contour that is a negative contour adapted at least partly to the contour of an object. Also disclosed is a charge plug for a transportation vehicle.

Abstract: Cleaning vehicle sensors, wherein position data of a vehicle are received (1). An unmanned aircraft suitable for cleaning vehicle sensors flies to the vehicle on the basis of the received position data of the vehicle, positions itself, on the basis of location data of a sensor of the vehicle that is to be cleaned, near the vehicle in such a way that the sensor to be cleaned can be cleaned, and cleans the sensor. The vehicle can transmit the position data of the vehicle to a Service Station via a mobile data connection, wherein the Service Station causes the unmanned aircraft to fly to the vehicle and, after the end of the cleaning operation, to return to the Service Station.

Abstract: A service station for vehicles of an autonomous vehicle fleet. The service station includes at least one service module that is designed to identify the dirtiness of at least one vehicle component of the vehicle. The service module also includes at least one mobile robot and/or a robot arm on which a tool is arranged for identifying dirtiness. The tool includes at least one optical sensor and preferably at least one light source and/or at least one vapor emitter.

Abstract: A parking robot for a transportation vehicle having at least two wheel axles and a method for operating a parking robot. The parking robot includes a main robot part and a secondary robot part which each have a pair of wheel support arms on two opposite sides. The two-part parking robot then moves under the transportation vehicle with respective folded-in wheel support arms and disconnects the secondary robot part from the main robot part to position the main robot part and the secondary robot part each in a region of one of the wheel axles beneath the transportation vehicle and to lift up respective wheels of the respective wheel axle of the transportation vehicle by folding out the respective pairs of wheel support arms.

Abstract: A mobile charging station for the electric charging of electric transportation vehicles having at least one battery unit, at least one charging interface for charging the battery unit, at least one second interface for charging an electric transportation vehicle from the battery unit, a method or mechanism for automated navigation of the mobile charging station and a method or mechanism for receiving a charging request. A method for charging an electric transportation vehicle.

Abstract: A transportation vehicle having a data interface for transmitting data to a robot, wherein the transportation vehicle includes a controller that produces control signals for controlling the robot for a specified working task and transmits the control signals to the robot via the data interface. Also disclosed is a method for controlling a robot by a transportation vehicle.

Abstract: A dual clutch transmission, especially of a motor vehicle, includes a hydraulic circuit with a pump for delivering a hydraulic flow, a cooler for cooling the hydraulic flow, and a volume control valve for adjusting the hydraulic flow for a cooling system associated with two clutches of the dual clutch transmission. The volume control valve is constructed as a switching valve with at least two switching position ranges, supplying the hydraulic flow to a first cooling system associated with a first clutch in a first switching position range with a constant flow cross-section, and supplying the hydraulic flow to a second cooling system associated with a second clutch in a second switching position range with a constant flow cross-section, wherein the entire switching position range of the volume control valve is substantially formed by the first and second switching position ranges and only a narrow transition range therebetween.
