Definitions
- the present disclosure relates to a self-propelled robotic tool comprising a work implement, a driving arrangement for moving the robotic work tool, a control device for controlling the driving arrangement, and an acquisition device, configured to record a signal transmitted in bursts by a boundary wire loop, wherein the control device is configured to determine whether the robotic work tool is located within an area defined by the boundary wire loop based on the recorded signal.
- Fig 3 illustrates an example of burst with certain signatures or patterns.
- the method may begin with clearing 45 the buffer 41 or memory.
- the system waits 47 an estimated period time P est , and thereafter samples 49 data input from the coil 23.
- the sampled data is added 51 to the buffer 41.
- adding is here meant that the received signal is added to corresponding data from previous pulses such that the value at a time t, v t is added to the corresponding value of previous pulses v t -p+v t -2 P +... etc.
- the sum in the buffer thus corresponds to an average of pulses received since the last clear event, even if not divided by the number of pulses.
- other and different FIR- and MR filter configurations are possible.
