FM sonar sensors have been used in mobility aids for the visually-impaired. However, previous FM sonar systems have generated continuous audio signals and rely on the user interpreting them. Our research work is carried out to solve the problem of overloading users of FM sonar system with excessive information by machine interpreting the audio signal. The(More)
In this paper, we describe the use of a broadband, frequency-modulated sonar sensor (a CTFM sonar) for generating maps of structured environments for robots and autonomous systems. The major advantage of using these sensors is that the information generated is reliable enough to extract the geometry and type of certain features with very few measurements;(More)
