In this paper, a technique to acquire modulation pulses for simultaneously working multiple supersonic wave sonars so as to decrease their errorneous measurement is proposed. Because the structure of the sonar can be implemented simply and cheaply, the multiple sonars are usually equipped on an autonomous mobile robot which moves the inside/outside of a building. Therefore, it is necessary to compose of the modula-tion pulses to meet the requirement to decrease the errorneous measurement between the sonars. Besides, a technique to minimize the length of the signal of the modulation pulses by using the genetic algorithm (GA), known as one of the optimization algorithms, is proposed in this paper. As a result, the more suitable modulation pulses can be obtained.
