"LoMoR" - Lets Orientate & Map Our Robots (Sonar Based)
Also Blogged as Mystery Object Here
My System Uses a LCD display to Map an area which is scanned by an Ultrasonic or IR Distance_ing transducer.
The Angle of the Probe is converted from polar Coordinate to Cartesian Coords and then displayed X,Y fashion on the LCD Display.
The System works pretty well i must say, however the "Extra" echos of Ultrasonic signal can be miss-leading.
