1. A robot comprising:
- at least one receiver for receiving a signal transmitted from a boundary, the transmitted signal including at least one positive pulse and at least one negative pulse within a predetermined interval;
a detector electrically coupled to the at least one receiver for detecting peaks in the signal; and
a processor in electronic communication with the detector for receiving the digital data associated with the detected major negative peaks and programmed to determine the location of the robot with respect to the boundary in accordance with the digital data;
wherein the detector for detecting peaks is for detecting major negative and positive peaks;
wherein the detector is configured for converting the detected major negative peaks into digital data;
wherein the processor programmed to determine the location of the robot with respect to the digital data includes being programmed to count the digital data in the form of pulses, and compare the pulses to predetermined pulse counts to determine the location of the robot.

Abstract
A system is employed for defining a position (location) of a receiving element inside an area surrounded by a wire loop, along the perimeter (a perimeter wire loop), of a work area or other bounded area. In particular, the system can determine whether the receiver is inside or outside the loop, and evaluate its distance from the perimeter wire.

2. A method for determining by a processor the location of a receiver, comprising:
-
providing a first loop including a first portion and a second portion; providing a second loop including the second portion and a third portion; providing a signal over a first loop and providing the signal over a second loop at a predetermined providing interval, the signal providing such that at least the first portion is always receiving the provided signal, the second portion and the third portion are receiving the provided signal in accordance with the predetermined providing interval; receiving the signal; converting by the processor the signal to pulses; counting by the processor the pulses for a predetermined receiving interval; and analyzing by the processor the counted pulses for the predetermined receiving interval against predetermined pulse counts for the predetermined receiving interval in accordance with the predetermined providing interval to determine the location of the receiver. - View Dependent Claims (3, 4, 5, 6)
