Abstract
Ultrasonic sensor arrays enable autonomous robots to explore the multidimensional space of their immediate surroundings. The aim of the demonstration is to show to what extent a 5cm broad array of three piezo-ceramic ultrasonic transducers is appropriate for getting two-dimensional impressions of the surroundings. Therefore, deviating from the pulse echo measurement techniques used so far, the time-continuous transmitting and receiving from modulated pseudo-random sequences are used. Thus the narrow bandwidth of a piezo-ceramic transducer can be compensated by an increased measuring period. Furthermore, the application of several robots in joined surroundings without interference will be possible, if suitable sequences are selected and appropriate correlation measuring procedures are used. Different software tools for the two-dimensional interpretation of the measured data show the efficiency as well as the limits of the demonstrated sensor.
