Abstract: A domestic robotic system includes a moveable robot having an image obtaining device for obtaining images of the exterior environment of the robot, and a processor programmed to detect a predetermined pattern within the obtained images. The processor and image obtaining device form at least part of a first navigation system for the robot which can determine a first estimate of at least one of the position and orientation of the robot. A second navigation system for the robot determines an alternative estimate of the at least one of the position and orientation of the robot. Calibration of the second navigation system can be performed using the first navigation system.

Abstract: A demarcating system for indicating the boundary of an area to an object (for example a robot, such as a robotic lawnmower), which has a receiver for receiving electromagnetic signals. The system includes a control system, a wire loop, a signal generator, and current sensing circuitry. The wire loop can be arranged by a user along a path, so as to indicate the path to the object as part of a boundary of the area. The signal generator is under the control of the control system with the voltage signals applied by the signal generator to the wire loop being controlled by the control system. The current sensing circuitry senses current signals present within the wire loop and the processors of the control system analyse such current signals. The processors of the control system are programmed to operate in a calibration mode whereby they: cause the signal generator to apply a series of test voltage waveforms to the wire loop, each of the test voltage waveforms generating a corresponding current waveform within the wire loop; and analyse the series of corresponding current waveforms, as sensed by the current sensing circuitry, so as to determine an operating voltage waveform that, when applied to the wire loop, generates a corresponding operating current waveform that is substantially the same shape as a predetermined current waveform.

Abstract: A mobile outdoor power equipment machine for performing a controlled task within a work area includes a drive system for providing movement of the machine, a working apparatus for performing the task, and a scanning system for scanning an area surrounding the machine. The scanning system is configured to provide detection of physical elements in the environment to aid in navigation of the machine. In an embodiment, the scanning system and a control system are configured to scan the area, determine the presence of a physical element in the area, determine that the physical element is located within the work area, determine the proximity of the physical element to the machine, and direct a behavior of the machine.

Abstract: A demarcating system for indicating the boundary of an area to an object (for example a robot, such as a robotic lawnmower), which has a receiver for receiving electromagnetic signals. The system includes a control system, a wire loop, a signal generator, and current sensing circuitry. The wire loop can be arranged by a user along a path, so as to indicate the path to the object as part of a boundary of the area. The signal generator is electrically connected to the wire loop in order to apply voltage signals thereto, such signals causing the emission of corresponding electromagnetic boundary indicating signals from the wire loop that may be received by the receiver of the object. The signal generator is under the control of the control system with the voltage signals applied by the signal generator to the wire loop being controlled by the control system. The current sensing circuitry senses current signals present within the wire loop and the processors of the control system analyse such current signals. The processors of the control system are programmed to operate in a calibration mode whereby they: cause the signal generator to apply a series of test voltage waveforms to the wire loop, each of the test voltage waveforms generating a corresponding current waveform within the wire loop; and analyse the series of corresponding current waveforms, as sensed by the current sensing circuitry, so as to determine an operating voltage waveform that, when applied to the wire loop, generates a corresponding operating current waveform that is substantially the same shape as a predetermined current waveform.

Abstract: A domestic robotic system includes a robot and data storage operable to store data defining a boundary of a working area, the robot includes a payload actuable to perform work on a portion of the working area adjacent the robot, at least one processor, a first positioning system, one or more sensors operable to sense directly the boundary of the working area and a current distance of the robot thereto, a second positioning system, which uses data from the sensors. The processor is programmed to operate in (i) an area coverage mode, wherein the processor, using the first positioning system and the stored data defining the boundary of the working area, navigates the robot around the working area, with the payload active, and (ii) a boundary proximity mode, wherein the processor, using the second positioning system, navigates the robot around the working area, in proximity to the boundary.

Abstract: Vehicle-mounted line trimmers and/or edgers for weed and vegetation, along with methods of operation of such trimmers, are discussed. The trimmer/edger can have a variety of features such as maintaining and/or adjusting the height of the trimmer/edger and maintaining the same orientation of the trimmer/edger at a variety of heights. The methods of operation can include methods for recording a path for the trimmer/edger and/or following a pre-recorded path for the trimmer/edger, trimming/edging around small obstacles, and trimming/edging along large obstacles.

Abstract: A system and method for proximity determination can include receiving an RF signal transmitted from a target location, the receiving performed by an antenna of an autonomous moving device, extracting received signal strength indicator (RSSI) values by processing the received RF signal, receiving distance measurements provided by a sensor associated with the autonomous moving device and storing the distance measurements in the memory of the autonomous device. The extracted RSSI values can be correlated the with the distance measurements to obtain a proximity value. A distance to the target location can be determined based on the proximity values.
