Ultrasonic Sensory System for Mobile Robots and Autonomous Vehicles

This work presents the proposal of a novel ultrasonic sensory system intended to be installed on mobile robots and autonomous vehicles. The system is capable to detect obstacles at distances up to 3 meters providing also information about their angular position, and all this information is computed rapidly enough as to be useful for the moving vehicle. The system proposal comprises the selection of suitable transducers, the design of appropriate driving modules, the planning of an adequate geometrical distribution of the transducers, the proposal of new encoding and modulation schemes, the development of signal processing algorithms, and finally, the hardware implementation of the detection modules.
