1. A robotic system comprising:
- a beam transmitter operable to emit a plurality of angularly-spaced beams of radiation in an area;
a robot operable to move within said area and to detect when it is in the path of one of said beams;
a reference transmitter operable to transmit a reference signal;
a timer, mounted on said robot, configured to commence timing upon transmission of said reference signal;
a pressure wave transmitter provided adjacent said beam transmitter, configured to transmit a pressure wave to said robot upon transmission of said reference signal, anda receiver, mounted on said robot, operable to receive said pressure wave;
wherein said robot is further operable, upon moving through a distance across the paths of two or more of said beams, to determine the relative position of said beam transmitter and said robot by using information relating to said distance and information relating to the spacing of said beams, andwherein said timer is operable to determine a time interval between the transmission of the reference signal and the receipt of the pressure wave and using the determined time interval to determine information regarding the position of the robot relative to the beam transmitter.

Abstract
A robotic system comprises a transmitter emitting a plurality of angularly-spaced beams of radiation in an area; and a robot moving within said area and able to detect when it is in the path of one of said beams. On moving through a measured distance across the paths of two or more of the beams, the robot can determine the relative position of the transmitter and the robot by using the distance and the angular spacing of the beams.
