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.

A demarcating system is discussed that includes a control system, a wire loop arrangeable by a user to indicate to an object path as part of a boundary of an area: a signal generator controlled by the control system, wherein voltage signals applied by the signal generator to the loop are controlled by the control system; and current sensing circuitry that senses current signals present within the loop wherein processors of the control system analyse such current signals and—operate in a calibration mode to: cause the signal generator to apply to the loop a series of test voltage waveforms that generate corresponding current waveforms within the loop; and analyse the corresponding current waveforms to determine an operating voltage waveform that, when applied to the loop, generates a corresponding operating current waveform with substantially the same shape as a predetermined current waveform.

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.

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.

The robot also includes a plurality of sensors, including one or more local environment sensors that are configured to receive signals from exterior sources local to the robot. The system further includes data storage, which is operable to store boundary information that defines the path of a predetermined boundary within which the robot is permitted to move. The robot is programmed to operate in at a reference trail recording mode and a navigation mode. In the reference trail recording mode, the robot moves along a reference trail while receiving sensor information from its sensors, with the path of the reference trail being calculated by the system based on the stored boundary information so as to be spaced apart from the path of the predetermined boundary. Also in the reference trail recording mode, the system stores reference trail information corresponding to a first plurality of points along the reference trail. This reference trail information is derived from the sensor information corresponding to the first plurality of points. In the navigation mode, the robot moves within the working area and navigates by: receiving current sensor information from its sensors; and, when it is in the vicinity of the reference trail, comparing the current sensor information with the reference trail information in order to determine its current position.
