Abstract: An autonomous mobile robot can include a body, at least one sensor configured to detect aspects of the environment in the vicinity of the autonomous mobile robot, and a control unit configured to process data received from the sensor to identify a position of a workpiece of the autonomous mobile robot and to define a safety field that has a position referenced to the position of the workpiece. The safety field is an area or a volume in which the presence of an object triggers a safety response by the autonomous mobile robot.

Abstract: A dual band antenna (AN) configured for being position on a surface of a pit lid and capable of wireless signal transmission at two frequency bands in response to an electrical signal applied via a feed wire. A convex conductive surface, e.g. 5 dome-shaped, is placed above a conductive ground plane element, wherein at least a part of an edge, e.g. 20-40% of the edge, of the dome-shaped radiator element is in electrical contact with the conductive ground plane element. Further, the convex conductive surface is connected via the feed wire. This antenna design allows first and second resonance frequencies within a factor of such as 1.8-2.2, 10 which allows the antenna to be designed e.g. for both of the frequency bands 450-470 MHz and 902-928 MHz which are relevant for meter reading data and with smaller dimension than what could be expected from conventional antennas.

Abstract: Automatic height control of a dozer blade, the input from the slow absolute height sensor is combined with an input from a gyroscope that measures the instant rotation and recalculates it into a vertical height change using the length of the supporting arms. The combination obtains the accuracy of the absolute height information and an increased speed of measurement resulting in a compensated height estimate that is input to a hydraulic control system of the feedback type. This enables much more aggressive control even though the hydraulic system has an unknown linearity and delay associated with it. The gyroscopic sensor forms an IMU with one degree of freedom to compensate for drawbacks of the absolute height sensor with regard to delay, noise and update rate to obtain a frequent, time-correct height position with a reduced level of noise by means of a calculation based on both types of sensor output.
