Abstract: A method for monitoring a robot arrangement, which robot arrangement has at least one robot includes capturing optical signals from a plurality of signal sources at least one sensor, wherein the signal sources and/or the sensor is/are positioned on the robot arrangement and triggering a monitoring reaction if a deviation of an actual arrangement of the captured optical signals from a desired arrangement of these signals exceeds a limit value. In one aspect, a reaction may be triggered if at least a predefined minimum number of signals from the desired arrangement is not present in the actual arrangement of the captured optical signals.

Abstract: A method for operating at least one robot includes determining the minimum distance of the robot from an obstacle, in particular the closest obstacle to the robot, in particular excluding at least one previously known, in particular temporary, obstacle; reducing the maximum speed of the robot if this minimum distance is below a first minimum distance; and reducing this maximum speed of the robot more if the minimum distance is below a second minimum distance which is smaller than the first minimum distance.

Abstract: A robot includes a robot arm having a plurality of motor-driven joints and a plurality of links, each of which interconnect two adjacent joints. At least one of the links has a supporting structural component configured to transmit forces and/or torques from an adjacent joint to the other adjacent joint. The structural component is provided with at least one covering that at least partially covers the structural component and at least one contact sensor. The at least one contact sensor is configured as a switching strip arranged between the structural component and the covering. Movable mounting of the covering on the structural component, which mounting is spring-preloaded into the basic position of the covering, is adjusted by an inherent elasticity of the switching strip.

Abstract: An autonomous vehicle includes a vehicle body having a receiving device configured to receive an object to be transported, a chassis having at least one driven wheel, and at least one sensor device having a detection region surrounding the autonomous vehicle for recognizing obstacles which enter the detection region in the immediate surroundings of the autonomous vehicle. The autonomous vehicle includes a joint arrangement configured to adjust the sensor device relative to the vehicle body such that the sensor device can be operated in a first arrangement which monitors the basic peripheral contour of the vehicle body, and in at least one second arrangement which monitors a total peripheral contour including the basic peripheral contour and an expansion contour of the autonomous vehicle that is formed when an object to be transported is received.

Abstract: A camshaft for an internal combustion engine has a fundamental shaft which has a first toothing designed as external toothing and has at least one cam element which is arranged on the fundamental shaft and has a second toothing designed as internal toothing, The cam element can be displaced in the axial direction relative to the fundamental shaft and is connected to the fundamental shaft in a rotationally fixed manner via the toothings. At least one of the toothings has teeth whose respective tooth width varies in the axial direction of the fundamental shaft.
